Why: learn that an acid mixed with a base causes a reaction
Alignment: SC 7th grade standards 7-5.6 and 7-5.10
Need: For 1 Volcano
1 daily newspaper
1 trash bag
1 plastic or paper cup
4 pieces of cut up cardboard
4 cups of water
2-3 cups of flour
Paint- red, orange, brown, green, etc.
4 tsp of baking soda
Red food coloring- 6 drops
10ml of vinegar
Create a Paper Mâché paste out of 2 parts water and 1 part flour.
Here are some links for other ways to make Paper Mâché
Give students a cup, some cardboard and newspaper. Have students frame the cup (which will be the inside of the volcano) with the cardboard. Begin pasting the paper to your cardboard and building the frame of the volcano. I know that is a very vague description, so here is a video on how to do a Paper Mâché volcano! It varies a bit from mine but you will get the idea. You can also see the pictures below to see how it was built.
Paint your volcano after it dries. We let ours dry over night but you could leave them for about 2 hours.
Move your volcano outside or to an easy clean up area. Put 4 tsp of Baking Powder and 6 drops of red food coloring in your volcano cup. Pour vinegar into your volcano opening to see a chemical reaction!
Why: learn to translate between metric and American measurements and learn to follow a recipe.

Need: For approximately 18 cookies
1/2 cup butter (1 stick)
3/4 cup of sugar plus 1 1/2 tsp sugar

1 tsp cream of tartar
1/2 tsp baking soda
1/8 tsp salt
1 1/2 tsp cinnamon
Large mixing spoon
1 Ziplock bag
I know I know, baking cookies doesn't seem like a math lesson. That was what the kids thought until they saw the directions! First off, I they were give a full recipe and told to make a half recipe. That required the groups to divide all of their ingredients in half. Next surprise, all of their ingredients were in Metric measurements and all of their utensils were cups, teaspoons, and Tablespoons! They were so mad at me!! I don't care though cause by the end they knew their conversions!
I am attaching here the documents that I gave the students. It has the directions and the conversions.
Once they were done being mad at me for making them use math, they really enjoyed it!
