Magnetic Pendulum
Source Institutions
In this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet.

Our Sense of Touch: Two-Point Discrimination
Source Institutions
In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

Junk-in-the-Box
Source Institutions
In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.
Bag of Bones
Source Institutions
In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.

Keep Out!
Source Institutions
In this technology activity, learners build an "alarming" doormat to keep siblings out of their rooms. Use this activity to teach learners about circuits, switches, and sensors.

Kick Stick Challenge
Source Institutions
In this design challenge activity, learners investigate series circuits and motors to build a hand-held "kick stick." Their goal is create a battery-operated device that sends a Ping-Pong ball across

That's the Way the Ball Bounces: Level 3
Source Institutions
In this activity, learners prepare four polymer elastomers and then compare their physical properties, such as texture, color, volume, density, and bounce height.

Kicking Machine
Source Institutions
In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.

Generations of Traits
Source Institutions
In this hands-on activity, learners track and record the passage of colored "pompom traits" through three generations of gingerbread people.

Finding Fossils
Source Institutions
This activity (located on page 4 of the PDF under GPS: Baby Dinosaurs Activity) is a full inquiry investigation to determine the age of fossils based on where they are discovered.

Growing Plants
Source Institutions
In this "Sid the Science Kid" activity from Episode 107: My Shrinking Shoes, learners observe how plants change as they grow.

Hot Spoons
Source Institutions
In this physics activity (page 2 of the PDF), learners will explore the concept of thermal conductivity and learn the differences between high and low thermal conductivity.

Clam Hooping
Source Institutions
In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

Silent Stalking
Source Institutions
In this outdoor game, learners role play predator and prey to explore the importance of keen hearing and silent stalking skills in the animal world.

Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

Isolation of DNA from Onion
Source Institutions
This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.

There’s No Place Like Home!
Source Institutions
In this activity, learners make their own bug boxes and test the habitat preference of selected "minibeasts" (bugs).

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

The Crayon Rock Cycle
Source Institutions
In this activity, learners use crayons to draw conclusions about rocks and the rock cycle.
