Roller Ball Painting
Source Institutions
This is an activity in which learners explore the effects of gravity, motion and momentum while creating art.

Changing the Density of a Liquid: Heating and Cooling
Source Institutions
Learners investigate how the temperature of water affects its density.

The Turing Test: Conversations with Computers
Source Institutions
This activity aims to stimulate discussion on the question of whether computers can exhibit “intelligence,” or are ever likely to do so in the future.

Space Elevator
Source Institutions
In this activity, learners imagine what the world might look like if we could build an elevator to space!

Electroscope
Source Institutions
In this activity about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.

Sweet Speedway
Source Institutions
In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

Flip
Source Institutions
In this amazingly simple physics activity (page 5 of the PDF), learners will explore how exerting a force on an object can give it kinetic energy and momentum.

Paint a Fresco
Source Institutions
In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

Exploring Magnetic Field Lines
Source Institutions
In this activity, learners explore the magnetic field of a bar magnet as an introduction to understanding Earth's magnetic field. First, learners explore and play with magnets and compasses.

The Face of Science
Source Institutions
Learners draw pictures of how they envision scientists. By comparing and discussing the features in their pictures, they can discover common thoughts and stereotypes about scientists.

Comparing the Amount of Acid in Different Solutions
Source Institutions
In this activity, learners use detergent solution to compare two solutions containing vinegar and cream of tartar.

Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Magnetic Pendulums
Source Institutions
In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

Dirty Oil, Oily Dirt
Source Institutions
In this activity, learners discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

Boats Afloat
Source Institutions
In this activity, learners discover what buoyancy is and determine the characteristics that make an object buoyant. Learners design, build, test, and evaluate boats made from a variety of materials.

Dinosaur Count and Sort
Source Institutions
In this activity, learners sort and count different colored plastic dinosaurs by various attributes including tail length, whether or not the dinosaurs have horns, etc.

Changing the Density of an Object: Adding Material
Source Institutions
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.

Balloon Impacts
Source Institutions
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.
