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.
Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Space Jell-O
Source Institutions
Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.
Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Stick to It: Adhesion II
Source Institutions
Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
Rocking Changes
Source Institutions
In this earth science activity, learners conduct a series of short experiments to explore how rocks change.
Stuck on You: Adhesion
Source Institutions
Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
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.
Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
