Make a Sun Clock: Tell Time with the Sun
Source Institutions
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.

Launch Altitude Tracker
Source Institutions
In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

Light is Made of Colors
Source Institutions
Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

Design and Build a Wind Vane
Source Institutions
In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

Cool It
Source Institutions
In this outdoor activity/game, learners use thermometers to simulate how lizards survive in habitats with extreme temperatures.

Standing in the Shadow of Earth
Source Institutions
This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

Water Exploration Station
Source Institutions
In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

Sunny Day Painting
Source Institutions
In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

Cook Food Using the Sun
Source Institutions
Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

Solar Cell Simulation
Source Institutions
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.

Sunblock Investigation
Source Institutions
In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

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

Cook with a Solar Oven
Source Institutions
In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.

Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

Exploring Shadows
Source Institutions
This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

FlyBy Math: Distance-Rate-Time Problems in Air Traffic Control
Source Institutions
In this small-group activity, learners assume the roles of pilots, air traffic controllers, and NASA scientists to solve five Air Traffic Control (ATC) problems.
