Graphing - Who can blow a bubble?
(have kids write how to blow a bubble)
(have kids write how to blow a bubble)
Geometry / 3D solids - Shape of the gum out of the wrapper (cylinder). Shape of the gum when blowing a bubble (sphere).
Measuring - Measure the length of the gum before and after being chewed. Have kids stretch their chewed gum out (as far as they can) and lay it on a piece of wax paper (make sure they have clean hands!).
States of Matter
solid - gum out of wrapper
liquid - saliva when chewed
gas - blowing a bubble
solid - chewed gum
solid - chewed gum
Ask kids if they think the gum underwent a physical or chemical change.
Answer - Physical change, there was nothing new created. Matter wasn't destroyed.
Next, have them write about how their gum physically changed (density, color, and temperature).
What made the gum get soft? Was it the saliva? Have kids place their chewed gum in ice water (or take a drink of ice water). They will notice that the gum will get hard. Does temperature play a role?
Mass
Predict: Will un-chewed, chewed, and chewed exposed to water have the same mass?
Lay the gum on a square of wax paper and compare it to a piece of un-chewed gum. Then, weigh gum that has been chewed and then exposed to cold water. Did they all weigh the same?
Writing
Have kids invent a new flavor of gum!
Design a shape for the gum.
Design a logo.
Design the packaging.
What will they call their gum?
Where can you buy it?
How much will it cost?
