in case you were wondering what i might be doing this afternoon. here is a sample of a crazy program that i am teaching for 3rd and 4th graders in an afterschool setting. Food Science. fun time.
HOW TO MAKE SLIME
CUP 1: 1 TABLESPOON OF GLUE
1 TABLE SPOON OF WATER
1 DROP OF FOOD COLOR
MIX WELL
CUP 2: 1 TEASPOON OF BORAX POWDER
1 TABLESPOON OF WATER
MIX WELL
POUR CUP 2 INTO CUP 1 AND GENTLY STIR. YOU WILL SEE A CHEMICAL REACTION OCCUR. YOU JUST MADE A POLYMER.
WHAT IS A POLYMER? A SUBSTANCE THAT POSSESSES QUALITIES OF A LIQUID AND A SOLID . SOME OTHER EXAMPLES ARE GUM, RUBBER BANDS AND JELLO!
HOW TO MAKE GRAPE SODA
· POUR ANY JUICE INTO A CUP ABOUT 3/4 FULL
· DON’T OVERFILL YOUR CUP
· ADD 1/4 TEASPOON OF BAKING SODA
· WATCH IT FIZZ
· ENJOY YOUR NONSUGARY SODA
The fizz will happen because juice contains citric acid. There is a chemical reaction between baking soda and citric acid. You can experiment with different types of juice.
Do you think orange juice will fizz more than apple juice?
The sugar that is in this soda occurs naturally from the fruit. There is no added sugar like you have in a regular soda. now you really can have soda for breakfast!
Just a day in the life...I really do have the greatest job. after that, i plan to enJOY my weekend. hbu??
