In this graphing activity (on pages 33-40), learners investigate how much and what kinds of food sea otter pups eat during their first year of life.

This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing).

In this activity (page 10 of PDF), learners approximate the area of the uppermost cross section of an impact crater using a variety of square grids.

In this activity, learners measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

This outdoor activity (on page 2 of the PDF under SciGirls Activity: Sand Dunes) is a full inquiry investigation into how the amount of moisture in a sand dune relates to the number of plants growing

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this activity, learners find Xi'an, the archaeological area in China where the Terra Cotta Army was discovered, on a map or globe and look more closely at the relationship of the warrior site to ot

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

This activity (on page 2 of the PDF under SciGirls Activity: Earthquakes) is a full inquiry investigation into aerial imagery.

In this activity (page 12), learners apply the concepts of pixilation and pointillism to the world of biomedical science.

In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

What is the optimal environment for hatching brine shrimp? Using a scaffold, learners design and conduct experiments testing the effect of a single abiotic factor on brine shrimp cyst hatch rate.
