The popular sudoku puzzles use numbers, but the game could played with any set of 9 different objects!

In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.

Using indirect methods, learners determine the shape and size of a piece of carpet hidden under a piece of plywood.

In this optics activity, learners explore diffraction by adding wax blocks to a ripple tank. The wedge-shaped blocks act as obstacles that the wave must bend around.

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

Learners explore the relationship between energy consumption, population, and carbon emissions in the countries of the Americas.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection

In this outdoor activity, learners first explore lizard feeding behavior by creating a "lizard rig" to dangle different objects in front of live lizards and see which objects the lizards try to bite.

In this activity related to rotational inertia (page 1 of the PDF under SciGirls Activity: Microgravity), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwi

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

In this health, cooking, and math activity, learners explore nutrition and examine nutrition labels.

In this activity, learners will explore how the human brain interprets environmental stimuli.

In this activity (on pages 2-8), learners experience how scientists use classification in their study of animals.

In this activity, learners build water-propelled engines from soft drink cans.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.

In this math lesson, learners participate in several activities where they apply measurement skills.

In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
