How do name-brand and non-name-brand baby deal- peers compare in terms of absorption? Suggested Time: Approximately 40 minutes. Materials: Each student will require: two clean baby diapers (name-brand and non- name-brand), two Zip-lock bags, two clear plastic cups, a pair of scissors, food color- Inning, a plastic spoon, and water. Preparation: Begin the lesson by talking about what actually composes a baby diaper.
Students will find out that there’s a lot more than meets the eye when It comes to the composition of these disposable diapers. Discuss the fact that there are crystals within disposable diapers, and that we will be experimenting with the water-absorb- tool properties of these crystals during the experiment. Doing the Activity. 1 . Cut down the center of the non-name-brand diaper. 2. Pull out the cotton. 3. Place the diaper and cotton into the Copilot bag. . Shake the bag for two solid minutes. 5. Pour the powder from the bottom of the bag Into the clear plastic cup. 6. Add water and food coloring to the cup. 7. Stir the concoction with the plastic spoon. 8. Turn the cup upside down (the mixture should remain firmly at the bottom of the up and should not fall onto the ground). 9. Repeat the previous eight steps with the name-brand diaper (but use a different color of food coloring).
Debrief/ Talk about it: What did we notice? The crystals from the name-brand diaper were able to absorb more water than the crystals from the non-name-brand diaper. This means that the crystals contained within name-brand diapers are stronger polymers than the crystals contained in non- name-brand diapers. Talk about what a polymer actually is, and why It Is important that polymers be strong and water- absorbent when It comes to baby diapers!
