Create a Compass
Source Institutions
In this activity, learners use simple materials to build their own compass.
Magnetism
Source Institutions
In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

Move That Lighthouse!
Source Institutions
In this activity, learners explore how engineers work in a team to solve problems.

Rubberband Rollback
Source Institutions
In this activity about potential and kinetic energy, learners get to roll a can across the floor and then watch it roll back to them as if by magic. This activity is always great for looks of wonder!

Making Waves
Source Institutions
Investigate the interaction of liquids of different densities and experiment with wave patterns with this hands-on activity.

Chromatography Observations
Source Institutions
In this activity, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

Inner Space
Source Institutions
In this activity, learners discover that there is space between molecules even in a cup "full" of water. They first fill a cup with marbles, and then add sand to fill the gaps between the marbles.

Ice Cream Shake
Source Institutions
In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

Electric Gelatin
Source Institutions
In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.

Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.

Color Splash
Source Institutions
In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

Design a Flavor: Experiment to Make Your Own Ice Cream Flavor!
Source Institutions
In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

Wonderful Weather
Source Institutions
In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

Reason for the Seasons
Source Institutions
In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

Plastic Milk: You can make plastic from milk
Source Institutions
In this activity (on page 2 of the PDF), learners make a plastic protein polymer from milk. Adding vinegar to milk causes the protein casein to solidify or curdle.

Energetic Water
Source Institutions
In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

Energy For Life
Source Institutions
In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

Does Air Weigh Anything?
Source Institutions
The demonstration/experiment provides quick proof that air has mass.

Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.
