In this activity, learners work in groups to create a time line representing significant moments in their lives.

In this activity, learners use simple materials to build their own compass.

In this data collection activity about crabs, learners use data from the Virginia Institute of Marine Science (VIMS) trawl survey to determine the areas of the Chesapeake Bay that are being used by bl

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.

In this outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.

Learners build models of sinkholes to gain an intuitive knowledge of their physical aspects.

In this outdoor activity, learners discover that plants aren't just shoots (stem, branches, leaves, and flowers) growing above ground, but contain plenty of roots growing underground—more than half th

In this activity (located on page 2), learners will construct tiny model geysers out of film canisters, warm water, and antacid seltzer tablets.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.

In this activity, young learners (2 years and up) explore dirt and what is in it by painting with mud.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this activity (page 1 of the PDF under SciGirls Activity: Dinosaurs), learners will model how paleontologists estimate the age of fossil discoveries by extracting “fossil” playing cards from newspa

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this activity, learners will build a bee hotel for pollinators. Learners will explore building and ecology through this activity.

Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.
