The peanut foams have an open-cell structure which will break down in water. Teacher will generate a discussion about packing materials to use to protect fragile items. Students are to decide which packing material is more useful for fragile items and will justify their answers. Teacher will ask two students to fill a box with the foam packing materials, place a jar or bottle inside the box, and seal the box with masking tape. The two students will decide on the height to drop both boxes to find out if the packing materials will protect the glass jars from breaking.
Students are to try again from a different height.
Teacher will ask students to tell what they noticed from both boxes being dropped. Students are to conclude that both foam packing material will protect the fragile items. Students are to observe what chemical reaction should occur from the mixture of the two and respond or record their answer. Students should notice that the yeast will bubble on the surface of the molasses causing a break down of the sugar in the syrup. Students will observe a chemical degradation.
