Exploring the Solar System: Pocket Solar System
Source Institutions
“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.

Molecules in Motion
Source Institutions
"Molecules in Motion" explores how materials behave and change in a vacuum.

Sand Grain Observations
Source Institutions
In this activity (on page 1 of the PDF under SciGirls Activity: Earthquakes), learners will use a magnifier to carefully examine samples of sand from different locations.

Zoom: Travel to a Star and Back to Earth
Source Institutions
This is an online activity about what would happen if we could travel at or near the speed of light.

Coral Snapshots: Biodiversity in Marine Protected Areas
Source Institutions
In this data activity, learners analyze data from coral reef snapshots taken by scientists at the Virginia Institute of Marine Science.
Pollution in Our Watershed
Source Institutions
By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

Build Your Own Solar Oven
Source Institutions
Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

To Topo Two
Source Institutions
In this activity, two groups of learners create two separate landform models out of clay (mountains and valleys).

What does Color have to do with Cooling?
Source Institutions
In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

Pie-Pan Convection
Source Institutions
It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

Why is the Sky Blue?
Source Institutions
In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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.

Glass and Mirrors: An Inside Look at Telescopes
Source Institutions
This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.
Bag of Bones
Source Institutions
In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

Discovering Rainforest Locations
Source Institutions
In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

Ocean Currents
Source Institutions
In this activity, learners will explore how density is affected by temperature and how that can create currents.

Why is the Sky Purple?
Source Institutions
This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

Exploring Black Holes and Gravity
Source Institutions
This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

Model Well
Source Institutions
In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

Finding Fossils
Source Institutions
This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.
