In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

This laboratory exercise is designed to show learners how DNA can easily be extracted from lima bean bacteria. This experiment requires the use of a centrifuge (not included in cost of materials).

In this activity, learners explore the concept of how aerospace engineering has impacted sports, specifically exploring the design of golf balls.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

This activity is about collecting and analyzing DNA as part of a criminal investigation.

In this activity, learners construct a three-dimensional ambiguous cube to explore visual illusions and how our brains interpret or misinterpret information.

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.

Ancient trash tells archaeologists a lot about the past. In this activity, learners take a close look inside their trash can and think about the clues it offers about their lives.

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 four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

In this quick activity (page 2 of PDF under GPS: Lava Flow Activity), learners will model how large depressions near the top of a volcano are formed by using an inflating and deflating balloon submerg

In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.

In this activity, learners explore how pens have been engineered and re-engineered over time. Learners work as a team to develop a working pen out of everyday items.

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 activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.

In this activity, learners will test the strength of different brands of paper towels.
