The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.

In this lab (Activity #2 on page), learners compare bacteria growth on two petri dishes containing nutrient agar. Learners touch the doors, faucets, etc.

Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

In this lab activity, learners act as fellow scientists and colleagues of Isaac Newton. He has asked them to independently test his ideas on the nature of motion, in particular his 2nd Law.

This is a great activity about human energy production. Learners will work out with a clothespin to investigate why hockey players jump on a stationary bike after an intense game.

In this activity, learners calculate the percentage of oxygen in the atmosphere by using steel wool's ability to rust.

This demonstration can be used to help learners visualize DNA by lysing (breaking open) bacterial cells on a slide and “stringing up” the DNA with a toothpick in less than one minute.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity (page 6 of the PDF), learners will observe both a chemical and a physical change.

In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th

Using indirect methods, learners determine the shape and size of a piece of carpet hidden under a piece of plywood.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this activity, learners explore clouds and how they form.

Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.
