In this interactive board game, learners "hire" different types of scientists to help canine character Ruff Ruffman solve unusual problems.

This hands-on astronomy activity lets learners hunt for different objects in the night sky that contribute to stellar and planetary formation, using a Treasure List.

In this activity on page 7 of the PDF (Water in Our World), learners make their own water treatment systems for cleaning water.

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity (page 23 of PDF), learners conduct an experiment to determine how the size and mass of a projectile affects the area and the volume of an impact crater.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

This activity shows how our experience of the Sun changes with time and location. The sun dagger at Chaco Canyon is thought by many to be a sort of ancient timekeeping device.

In this activity, learners construct a traditional handicraft toy that illustrates a motion commonly associated with violins and earthquakes.

Learners develop an understanding of air pressure in two different activities.

Learners build devices from rubber bands to test for invisible air pollutants.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

In this activity about saturation (page 1 of PDF under SciGirls Activity: Sand Dunes), learners will build a series of sand castle towers using a 16 oz cup.

In this family or group activity, learners conduct a chromatography experiment to reveal the colors that leaves "hide" under their green pigments.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

In this activity, learners explore dinosaur skeletons.
