Source Institutions
In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

Pre-School Ball Run!
Source Institutions
In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.
Magic Wand Creations
Source Institutions
This is an activity in which learners create magic wands from a variety of materials making their choices by considering what kind of magic they want to make.

Water Sphere Lens
Source Institutions
In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

Eddy Currents
Source Institutions
In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

Real Glass Xylophone
Source Institutions
In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.

From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.

Planaria Fishing

The Ripple Tank
Source Institutions
In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.
Polarized Light
Source Institutions
In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Source Institutions
In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

Membrane Permeability with Beets
Source Institutions
In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

Get the Porridge Just Right
Source Institutions
Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

Lagging Sound

In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.

Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.

Feeling Pressured
Source Institutions
In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
Five Second Dash
Source Institutions
This is an activity about prediction. How far can you hop in 5 seconds? Could you make it to the door? Across the room? Everyone lines up and tries it.
