Then I informed them of making a model this week. They were so excited, and so was I!!! I told them for homework they had to bring a batch of play dough (not store bought) to school by Thursday, and I supplied them with this recipe. We would color it Thursday, and make the models on Friday. FYI: We had lots of left overs from this recipe!
Wednesday the students researched through reading different books that I placed at their table, and wrote just facts under each flap of each layer of their foldable. The last 20 minutes or so we talked about making our model to scale. My students are 6th graders, and in math we do A LOT of proportional studies. So we naturally made our model to scale. Using some measurements given to us in our textbook, and this worksheet
- Crust : 1 mm
- Lithosphere (mantle part only): 1mm
- Mantle: 4 cm
- Outer Core: 3 cm
- Inner Core: 3 cm diameter.
The students were very careful with their measurements. Here are a few pictures of the project in motion....
Warning: Those of you who are afraid of chaos and mess ( like me) please take a deep breath before viewing.
|Each table placed their colored play dough in baggies and in a bucket which made it easy to pass out today.|
|Making that Outer core 3 cm. SCALE!!!|
|Careful tick marks at 4 cm makes it easy to keep the right measurements.|
|Love how they used their sheets, without me saying anything!|
|It's hard to make it 1 mm thin!!!|
|Lots of colors and lots of fun!|
|Keeping it accurate!!!|
|Thinning out the Lithosphere.|
|A final project with flag labels and all.|
|Another nicely finished model|
