You have probably seen it on You Tube™ — the exploding Coke® and Mentos® experiment. But what is it that makes the reaction happen, and what factors cause a larger or smaller eruption? In this science project, you will see if using crushed Mentos candies, instead of whole Mentos candies, will affect the reaction. Read more

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more

There are currently two different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g. Saran or Glad Wrap) and polyvinyl chloride (PVC) (e.g. Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film). Which of these materials is less permeable to oxygen? When you slice an apple, the surface of the slice turns brown as the apple is oxidized. Can plastic wrap seal out oxygen and prevent the apple from browning? Which plastic wrap works best? Do… Read more
