In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

In this activity (pages 17-31), learners are introduced to techniques that are used to determine the structures of solid materials.

In this activity, learners construct a robot-like hand to demonstrate how data is collected when using robotic technology.

In this activity, learners create their own archaeological profiles.

In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

In this outdoor activity/field trip, learners investigate the special shapes, holding structures and holding behaviors that real organisms use in streams, rivers, creeks or coast intertidal zones to a

In this activity, learners investigate passive solar building design with a focus solely on heating.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

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

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.
