Before there were clocks, people used shadows to tell time. In this outdoor activity, learners will discover how to tell time using only a compass, a pencil, a handy printout, and a sunny day.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this activity, learners use simple materials to build their own compass.

In this activity about magnetism (page seven of the pdf), learners experiment with magnets to better understand how magnetic fields work.

In this activity, learners conduct an experiment to find out if steel wool will weigh more or less when it is burned. Learners will explore the effects of oxidation and rusting on the steel wool.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

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.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

"Exploring the Solar System: Hide and Seek Moon" is an engaging way for early childhood learners to experiment with some of the tools scientists use to study objects that are very, very far away, and
