In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

Learners look at labels on items in the room to determine where each item was manufactured, then write about the item on an index card.

In this engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.

In this activity, learners will use household items to design and build an elevator that will carry 2 passengers to a height of 16 inches...or higher!

This activity about cryptographic techniques illustrates how to accomplish a simple, but nevertheless seemingly impossible task—making a fair, random choice by flipping a coin between two people who d

In this outdoor activity, learners use pegs (like tent pegs) and string or elastic to simulate drill sites and roads in Northern Canada.

In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.

This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.

In this chemistry activity, learners use chemical reactions to observe the composition of an alloy.

In this activity, learners design and build a simple wind vane —one of the oldest kinds of weather tools— and use it to show wind direction.

In this activity, learners build an electromagnet using a nail, a cork, a battery, and electrical wire. Use this activity to demonstrate how electric currents produce magnet fields.

In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.

In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this design challenge activity follow up to "Kicking Machine", learners add a hands-free feature to their Kicking Machine.

In this design challenge activity, learners build a car that uses a battery-operated motor to "drive" at least ten feet.

Experiment with force and pressure by building a balloon rocket. When launched, the balloon will run a track wherever you place the string.

In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!
