What to Do
-
Help your child to search your home to track down everything that she can that is sticky. See how many of the following she can find:
- Tape
- Peanut butter
- Postage stamps
- Envelopes
- Honey
- A decal on a t-shirt
- Spackle
- An adhesive bandage
-
Ask your child to make a list of things in nature—animals, plants and so forth—that have adhesive properties or are sticky. For example:
- Spiders that use sticky threads to create webs to catch their food
- Tree sap
- Barnacles that stick to boats, ships and rocks
-
Next, ask her to think of adhesives that are used in hospitals? in offices? in auto repair shops?
-
Help your child to make a poster or collage using adhesives by doing the following:
- Make three bowls of flour-and-water paste. In each bowl, add 1/4 cup water to 1/2 cup flour and mix until smooth. Add a different-colored food coloring to each of the three bowls and mix. Use the pastes to make colored shapes on a poster board or heavy paper.
- Crack open an egg and separate the white into a bowl. Use the white as a clear glue to attach aluminum foil, cotton balls, toothpicks, cloth, glitter, ribbon, yarn and colored paper—whatever works to create a collage.
