This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.

In this activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this quick activity (page 1 of PDF under SciGirls Activity: Lift Off), learners will use the ever-popular soda geyser experiment to test the reactivity of the various sugar candies or mints.

In this activity, young learners will make their own flower seed nursery in an egg carton.

In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.

This fun, nighttime hands-on astronomy activity lets learners explore how long it takes for light from different objects in the universe to reach Earth.

In this activity, learners use their hands as tools for indirect measurement.

In this activity, learners will make their own prism and use a glass of water to separate sunlight into different colors.

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.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements.

In this activity, learners model erosion using a clear shoebox and sand or soil.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

In this activity (located at the top of the page), learners make an easy river strainer and see what they can catch.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.
