Science and Engineering

IMG_2813Back in November I wrote a blog about the excitement of launching marshmallows. Recently, though, I had a teacher ask me how do you turn a simply activity like that into an opportunity for students to practice thinking and working like an engineer? Simple-just ask them to S.C.A.M.P.E.R.!

 

SCAMPER is a mnemonic that stands for:

  • Substitute
  • Combine
  • Adapt
  • Modify, Magnify, Minimize
  • Put to another use
  • Eliminate
  • Reverse

Robert (Bob) F. Eberle was an educational administrator in Edwardsville, IL. He wrote about creativity for children and teachers. I like to think of SCAMPER as a creative thinking tool that helps people to think of changes they might make to an existing product in order to design something new.

Essentially students go through a brainstorming process that allows them to work through each letter and then pick one or two ideas they would like to try.

Here is how I used the strategy with my own children. As with any new strategy, it is better to teach them with something that had nothing to do with any content. We started with coming up with ideas to design a better Starbucks cup!

Before I tell you what my kids came up with, let me say I had to stop and do a little observing/researching first with them! I quickly realized my children had no knowledge or understanding of how the cups were made and the materials that were used. Without this understanding, the brainstorming process would have been a little more challenging.

Here is the list of observations we made about our cup:

  • Made out of cardboard
  • top is plastic
  • has a number 6 printed on it
  • green logo for company
  • sleeve around coffee cup is made of cardboard
  • cup is white

The observation about the number 6 on the top of the cup generated a question-what does that mean? So we googled it (what would we do without google!).  What we learned was really neat.

Did you know that number 6 stands represents that the object is made of  Polystyrene. It is a petroleum-based plastic made from the styrene monomer. You might know it under the name of Styrofoam.  Polystyrene is a light-weight material, about 95% air, with very good insulation properties and is used in all types of products from cups that keep your beverages hot or cold to packaging material that keep your computers safe during shipping. It can be recycled.

Of course, this led my children to ask more questions about the Starbucks cup. We found this great website and discussed why Starbucks did not use styrofoam for their cup design. My children also wanted to know the purpose of the cardboard sleeve that goes around the cup. To show my kids why it was important, I heated up hot water and poured it into the cup. They then felt the cup with and without the sleeve on. Both of my kids quickly announced you want to use the sleeve so you don’t burn your hands!

Although it took some extra time to do this researching process, it was well worth it!  I felt that when they started brainstorming, they were coming up with good ideas and not guesses.

Alright-time to SCAMPER!!IMG_2810

I created a template so my kids could write down what they brainstormed (we talked about how scientists and engineers write down their ideas!) in terms of ideas for improvements and the benefits.

Here is what my kids generated:

S-What if we used colored cardboard material? Benefit: we could color the cups to match the seasons. Cardboard Sleeve-put the Starbucks logo on it as well as on the cup. Benefit: when the sleeve is on the cup, the sleeve blocks the logo-better marketing!

C-What if we made a cardboard handle like a real coffee mug only made of cardboard. Benefit: easier to hold. What if we combined the coffee mug with water bottle. Benefit: you could carry coffee in your water bottle.

A-What if the lid had a built in straw? Benefit: easier to drink. Adapt the logo to have seasonal images. Benefit: fun and festive-think of leaves around the lady in the fall.

M-Enlarge the cardboard sleeve. Benefit: better protection for your hands. Modify the shape-use a square shape. Benefit-if you order drinks for your kids, less likely to drop them-squares are easier to hold.

P-Design the cup so it could be used as a planter-the material in the cup could be biodegradable and then it would break down as the plant grew. Benefit-you could save all your old cups and plant plants or flowers.

E-Redisgn the lid. Benefit: so it won’t leak

R-Rearrange colors for season. Benefit: People might like to have colors to represent the seasons.

As we were going through the process, my daughter kept saying she really liked the process. I loved how they would just ping ideas off of each other. They were generating so many ideas it was hard for my son to write them all down! I personally like the different colors for each season! Who wouldn’t want a fantastic cup of coffee in the springtime in a bright, pink cup!! Two things that make me very happy!

Have you tried this strategy in your classroom? If so, leave me a message and share how you use it!  If you are interested in more ideas, take a look at a lesson I wrote off of the launching marshmallow idea! Just click here! I also have the strategy and the sample template I used. You can find it here.

Go Science!

Sharing Science is an Adventure!

Click clack, click clack, squeak, squeak. Ommmmmm, Ommmmmm. Nothing like the sounds a train makes as it rolls down the tracks through fields, over rivers, and through small towns! Today I am heading off on a science adventure to Washington D.C. Yep, Dr. Jenny Sue is going to Washington!  Don’t worry I have not become a politician but instead will be representing the Virginia Association of Science Teachers at the annual Center for Excellence in Education’s Congressional Luncheon. Would you agree with me that a mentos and diet coke explosion is perfectly suited for the steps of the capitol building!

In planning my trip, I dreaded the thought of having to drive to D.C. You all who live here know how crazy traffic in Northern Virginia can be throughout the day! So when my wonderful husband said why don’t you take the train, I jumped on the idea! I had no clue Amtrak had extended coverage to include a stop in Norfolk. Check this out-you can get a round trip ticket to DC for just around $100. If you book your trip early enough, you can get the tickets for some really great prices. But know this-your day starts really early! I was up by 3 a.m. to ensure I was ready to walk out of the house by 4 a.m.! Train pulls in the station promptly at 4:30 a.m. and is off by 5 a.m. By 5:30 I had blown through Suffolk and by 6:30 a.m. was pulling into Petersburg!!

Food and beverages are served on the car (reasonable price) and will be excited to try dinner tonight (will post about my experience later)! Here are the things I love so far:

  • No traffic! Just the thought of having to find a place to park in DC made me sick! I have to say there is something relaxing about sitting and watching the scenery go by!
  • Virginia is a beautiful state! Nothing better than watching the sun come up from the window of a train! When we crossed the James River, it was impressive. With all the rain, the river was rushing to go downstream to the bay! Good day for a little rivah white water rafting!
  • Free WiFi that had incredible connection! I know what you are thinking! I should have just enjoyed the ride. But those of you that know me know I can’t sit still for very long. 8 hours on a train is a long time and if I can crank out some lesson plans or get some sessions developed, then I can have more free time this summer!
  • What other method of transportation allows you to race a freight train going 60 miles per hour? The cover picture was taken as we caught up and passed a huge freight train that rolled passed us in Petersburg! Felt a little uneasy and was praying I would not be reenacting scenes from the movie-unstoppable! But exciting none the less!

If you are up for an adventure, why not try the train next time you want to go to DC!!

 

 

Recycled Bottle Project

Sorry I have not posted in a while! Things have been really busy for me these days. I had several classes to develop and teach along with preparing handouts for my sessions at the I Teach K conference this summer. But I am back in the swing of things!

With Earth Day coming up, I thought I would share this activity with you! This is one of those activities where you can get a lot out of it. Not only can you use it to talk about reusing items in a different way, but if you are working with having your students show you they know how to create a pattern, this activity is perfect for that! I love when activities are simply and full of learning possibilities! But I have to admit, this is a really cute activity as well and kids from all ages love it!  Even my kids loved creating these whimsical creations! All you need are the following materials:

  • IMG_2399used water bottleIMG_2400
  • colorful sharpie markers
  • pair of scissors

 

 

Here is what you do:

IMG_24011.  Have the kids color the water bottle. If you want to connect the activity to math, have them first draw their pattern out. This is a great way to reinforce the idea of ABAB or ABCABC or even the ABCDABCD patterns!  I have even created a red, white, and blue pattern which will be hanging from our trees on the 4th of July!

2. Staring at the bottom of the bottle, use the scissors to cut a small hole. Then you simply cut around the bottle.

IMG_24033. Continue cutting around the bottle until you get to the top. At this point, you can actually pull the bottle apart and it should stretch out.

4. Tie a string through the opening of the water bottle.

 

IMG_24045. Hang and enjoy your beautiful work of art!  For a video showing you how to cut the bottle, click here.

I hope you have as much fun as I did with this quick and easy project.

Share Love with a Little Science!

When I was teaching I always made my kids a little something for Valentines Day! I knew that for many of my children, the handmade card they got from me would be the only card they would get! Many of my children just could not afford to buy cards to share.

Last year I shared with you how you could use coffee filters and a little science to make cards for your students or even have your kiddos make cards for their parents. As I was thinking about this year, I thought, hey-why not do a different version of the same idea. But this time, how about making some cute things for mom and dad!!

Here is what you need:

  • Rubbing alcohol
  • Dropper Bottle
  • Sharpie Markers
  • Bowl
  • Lots of space to work!

I actually found these really cool 80’s sharpies at Walmart!! I really liked the bright, bold colors!

IMG_2203Once you have all your materials ready, the next step is you draw! Think about using shapes, or patterns with spaces between them, or even dots. In terms of colors, remember what you learned in elementary school-which colors are primary and which are secondary? Primary colors are only made of one color. When the liquid is added, all you will have spreading will be that color.

If you want to have multiple colors spreading out, then you need to go with a secondary color. For example, if you use green, you will see yellow and blue colors bleed out.  For more on this process, check out my lesson plan What is Black-Looking at Color from a Different Perspective. This lesson plan has kids learn this process by using washable markers.

Here are the shapes and patterns I used:

IMG_2215IMG_2214IMG_2213IMG_2205

 

 

 

 

 

The materials I used consisted of a bandana from Walmart and a polyester hat from Michaels. I thought of the bandana because I knew I could cut out squares and have my kids make make handkerchiefs.

Really you can’t go wrong with this project. The key is to remember the more space, the more the colors will have a chance to run. Sometimes if they run into each other, they make their own colors!!

Here is a great connection to math! Kids have to learn to recognize patterns. Instead of doing patterns on paper, why not reinforce them with this project! Check out this again-do you see the pattern I made?

IMG_2214

If you look closely, you will see the bottom row reflects the ABAB pattern. The second row is ABBABBA, the third row is ABA, and the last row is back to ABAB!! What better way to have your kiddos show you they understand how to build a specific pattern by making them! And if the can make them into gifts for someone special, even better!!! To me, I would rather spend my instructional time assessing students on their understandings through activities like this instead of paper/pencil any day!

IMG_2207Okay-so once you have your design done, all you do then is just drop drops of alcohol onto the colors!! The reason we are using alcohol for this project and not water, has to do with the make up of the pens. Because they are permanent markers, they are made with colors that are not soluble in water. In other words, water is not strong enough to separate them out. Remember, chromatography is a process used to separate different compounds.  The origin of the word is from greek-chromatos meaning color and graphein-to write.  In essence, the process involves separating chemicals and identifying them by color!

In case you want to know what it is used for-here you go! The process has many uses. Commonly it is used to isolate new compounds, analyze differences between samples of objects, and it is even used in sequencing of DNA! Really all you need to do the process is a material (hat and bandana in this activity) and the “sample” (in this case the pen color) that is applied to the material. How the material is made will determine the rate of flow of the breaking apart of the sample. In other words, if you use a material that is very porous-like cotton, then you will be able to get the colors to bleed really well. That is why paper towels or coffee filters work so well!

Enough of the science, are you curious about how my projects turned out?? I think they all turned out really cute!!

Science is all about Repeated Trials!

IMG_2080I wish I could get every science student to understand this one key fact-the greatest discoveries have came from failure.

All too often, students think the “science fair” project is the end; but really it is just the beginning! Sometimes scientists experience times when things don’t work or don’t go as they thought it would. Simply put, what they learn is their data does not support what they hypothesized would happen. And you know what, it really is okay!

Take for example my  freezing bubbles activity. I managed to get it to work back in December when it was really cold. But the second time I tried to do it, it didn’t work. No matter what I did, I could not duplicate what happened the first time. This drove me crazy. In fact, I felt really bad. Several of my friends were trying it as well and could not get it done either!!

Then a friend of mine sent me a message with a different bubble solution. Since we had such cold temperatures today, I  experimented with changing the bubble solution. Guess what!! It worked!

Although the bubble did not freeze all the way like last time, you could see the ice crystals forming from the bottom up. Here are some pictures I managed to get:

IMG_2073

IMG_2054

In the first picture you can see the bubble before it pops! The second picture shows the frozen remains of the bubble. I love how you can see the colors!

Here is what my experimenting showed me-you need to add something to the bubble solution to make it stronger. I added Karyo syrup to my solution of dawn soap and water. In fact, here is the receipt:

3 cups water; 1 cup Dawn soap; 1/2 cup of clear Kayro Syrup

From Silly Putty, corn flakes, even the microwave oven, some of our greatest inventions came from mistakes! So if your children want to give up when their experiments don’t come out like they thought, just have them keep going!

 

 

 

Snow Day is Science Day!

We had a rare treat this morning-snow! Virginia Beach does not see too much of the white stuff so when we do, it normally shuts down the entire city! As I went outside today to play with my son, I was in awe of how beautiful snow makes the world!

IMG_1977

From the trees to the ground, everything was covered in snow. Of course those of you who know me well know I could not stop thinking about the science behind snow!

Not to take anything away from snow, but it is just water in a different form. Simply put, water is nature’s magical substance! At one temperature it can take the form of a solid known as ice or snow while at another temperature it is a gas. To make it change, you need to change temperature. It freezes at 32 degrees F and boils at 100 degrees F. We can’t live without it for more than three days. And yet, when it freezes, depending on how fast or slow it freezes we get two completely different things-ice and snow!IMG_1985

When the air temperature hits 25-32 degree, these crystals form in thin, hexagonal plates. If the temperature continues to cool-around 21-25, the crystals form in more needle-shapes. Beyond that you tend to get different shapes such as hollow columns or hexagonal plates with indentions, and even branched shapes.IMG_1984

Water also allows us to begin to teach young children how to work like scientists to compare and contrast. Using strategies such as a Box and T chart allow our young scientists to learn how to focus on differences while identifying those things that are the same.

If you were lucky enough to get some snow today, take your kids on a hike and look for the differences between the snow and ice! For more ideas, check out a free lesson plan I have on Teacher’s Pay Teacher’s site. Be sure and save some snow to take in tomorrow for your lesson! Just click here to find the lesson plan!

Frozen Bubbles

Wow!! It has been a while since my last post! I hope those pumpkins came out as fantastic as mine did!

Happy New Year! I can’t believe another year has come and gone! But I am ready to see what 2014 brings!

Back in November, a friend of mine sent me a link about activities you can do during the winter months. One of the ideas dealt with freezing bubbles. Today I saw another post (see here) and since we had temperatures below freezing (it was 29 when I did this), I decided to see if there was any truth to the story.

I have to say-this is so cool! Of course I think mine would have worked better if it was colder outside (in the original post it was 16 degrees-now that is cold!).

Here is how I did this activity:

I got a bowl and added some cold water to it. Then I added dish soap (Gain was what I used-I would recommend Dawn as it seems to make better bubbles). I then got something I knew would make a bubble (I did not have a bubble wand)-so I used a spoon with holes in it.  And presto!! Bubble on table.

IMG_1861

If you look carefully, you can see the crystals forming on the bubble. It took about 5 minutes for the entire thing to get crystalized and turn to a solid. Of course the scientist in me wanted to really see if it was frozen so I touched it-and sure it enough, it was! Here is the picture of the hole that was made after I touched it.

 

IMG_1869

Do you see the hole?? I then thought about this past summer when I blew bubbles with a  sock (click here for post) and thought-I wonder if a stream of bubbles will freeze?? So, I grabbed a sock and tried it out. I found out this does not work as well as a single bubble. I am thinking as the crystals started to form, due to the many bubbles, the action of growing the crystals made the bubbles very unstable because they started popping. I would love to see what kind of creations you come up with!!

Here are some more pictures of my science fun! Be sure and come back and share your pictures!! Go Science!
