Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.

This activity (on pages 7-13) has pairs of learners survey an array of similarities and differences between them.

In this activity, learners take on the role of various parts of the cell in order to model the process of protein synthesis.

In this weather activity, learners build their own wind detector and test for the presence of convection currents in their indoor location.

In this activity, learners will explore surface tension, what it is, and how we can change it.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this activity, learners use multiplication skills to get groups of aliens safely back to their planet.

In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

Even fast computers are limited to how quickly they can solve problems. One way to speed things up is to use several computers at once.

In this demonstration, learners observe the effects of density and pressure by attempting to make "balloon kebabs." Learners will try to insert a wooden skewer all the way through an inflated balloon

Learners develop an understanding of air pressure in two different activities.

Learners build devices from rubber bands to test for invisible air pollutants.

In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.

In this activity, learners design and build a toy top out of simple, everyday materials and have the option to use the toy as an artistic tool.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

In this activity, learners make and test fly paper helicopters. Learners use templates to create paper helicopters and then take take turns flying them in the air.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
