In this goopy activity (page 2 of PDF under GPS: Glaciers Activity), learners will model glacial movement with “gak,” a white glue and liquid starch mixture.

In this math activity, learners earn "money" by completing simple tasks. Learners complete as many "jobs" as possible in a set amount of time.

In this math activity, learners play a game using their number sense to make the highest or lowest number possible. Use this activity to explore place value and/or decimals.

In this activity, learners will use static elecricity to bend a stream of water without touching it. Learners will explore physics and cause and effect through this activity.

In this Cyberchase activity, learners make decoders to send and receive secret messages. Learners make the device out of two 8-ounce cups and two code strips.

In this math activity, learners use a "function machine" to collect and organize simple data. The function machine in this case is a cardboard box and the input/output data are paper fish.

In this online interactive simulation, learners will test the pH of liquids like coffee, spit, and soap to determine whether each is acidic, basic, or neutral.

In this math lesson, learners follow step-by-step directions for making tangram pieces out of folded and torn paper. First, learners read "Grandfather Tang's Story" by Ann Tompert.

In this game, learners are stuck in a right turn only world! Learners take turns rolling a die and moving their game pieces along the lines of a grid to get "home," by only making right turns.

In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this activity (26th on the page), learners construct an easy-to-build device and test motor learning.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners make three different "seed" types and determine which design flies the farthest.

In this mathematics activity (page 4 of the PDF), learners will explore the relationship between the diameter and circumference of an object.

In this activity, learners participate in fun movement activities while playing on a giant game board. Use this activity to get learners involved in physical activity.

In this quick activity about the properties of water (page 1 of PDF under SciGirls Activity: Malformed Frogs), learners will use an eyedropper to slowly place one drop of water at a time onto a penny,

In this activity, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.
