In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this online game, learners must purchase power plants for their city.

In this activity, learners design a bungee jump for an egg using nylon stockings.

In this math lesson, learners use simple addition facts to compute values (in dollars and cents) for their names.

In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.

In this activity, learners will take a walk with their family and incorporate a scavenger hunt. They will explore topics like ABC’s, numbers, colors, and shapes as they search for related items.

In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

This quiz lets you estimate your annual radiation exposure.

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.

In this activity, learners explore the concept of force and how pulleys are used in everyday life to make work easier.

Learners build 3D representations of constellations, which show not just the position of the stars as seen from Earth but also their relative distance from Earth.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

In this activity, learners will explore the foods that are in their kitchen and what sugars are inside of them. Explore nutrition and food labels to better understand the foods you eat.
