In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

Los jugadores toman turnos para añadir figuras de tres cuadrados a la cuadrícula. Intenten encajar sus figuras en la cuadrícula de modo que bloquee al otro jugador.

In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this activity about problem-solving, learners build a house for the Three Little Pigs using twenty straws and two index cards.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.

In this activity, learners explore geometry and spatial relationships as they figure out how to arrange tables for a party.

In this math activity, learners use cubes to calculate how many blocks it would take to build stairways with different heights.

In this activity, learners explore fractions as they help gators share pies.

In this math activity, learners make a set of fraction cards to play a game that will help relieve their fraction frustrations.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.

In this activity, learners conduct an experiment to help Pharaoh design a better insulated tomb.

In this activity, learners will decide together on a question about how far, long or high the group could reach together.
