Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

This activity (on page 3 of the PDF under GPS: Roller Coaster Design Activity) is a full inquiry investigation into g-force and acceleration.

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 activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.

In this activity, groups of four learners must complete a set of four manual tasks. The restrictions are that they must complete the tasks in a limited time while wearing garden or rubber gloves.

Build a musical ice theremin by programming a micro controller, like a Pico Cricket to respond to resistance generated by the ice melting, or the ice being touched.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

Learners participate in a variety of activities modeling different disabilities.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this activity, learners explore the concepts of natural selection and observable traits in a game that can be played at home.

This activity (on page 2 of the PDF under SciGirls Activity: Rabbits) is a full inquiry investigation into observing, recording, and graphing animal behavior.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this activity, learners conduct a scientific investigation involving decomposition and discover that the life cycle of trash is affected by its organic or inorganic nature.

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 activity, learners make a black box device that serves as an excellent analogy to Rutherford's famous experiment in which he deduced the existence of the atomic nucleus.

In this demonstration, learners explore a variation of a Foucault pendulum, but upside down.

In this chemistry demonstration, acid rain is simulated in a petri dish.

In this activity, learners make a model of a beehive using simple materials.

In this classic memory game (on pages 37-45 of PDF), learners turn over tiles to reveal images on the back.
