Rhythm Painting
Source Institutions
In this activity, early learners create paintings by making music and rhythm. Learners place paper in cans, add paint-soaked beans (or pebbles) and put the tops on.
Model Eardrum
Source Institutions
In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.
Magnet Powered Pinwheel
Source Institutions
Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.
The Incredible Journey
Source Institutions
In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.
Don't Throw it in the Garbage
Source Institutions
In this activity, learners discover why only some types of plastic can be recycled.
Sugar/Salt Crystals
Source Institutions
In this chemistry activity (page 1 of the PDF), learners will observe a physical change.
Bendy Bones
Source Institutions
In this activity (on pages 19-24 of PDF), learners soak chicken bones or eggshells in vinegar for several days.
Cave in a Cup
Source Institutions
In this activity (page 2 of PDF under GPS: Cave Swallows Activity), learners will model how caves are formed by placing one piece of chalk in a cup of vinegar and another piece in a cup of water, then
Static Cling
Source Institutions
In this activity, learners investigate static electricity using everyday objects at four different stations.
Soap Bubble Art
Source Institutions
Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.
Blimp Jet Challenge
Source Institutions
In this design challenge activity, learners add a jet-propulsion system (i.e. a balloon) to a blimp so it flies straight and far under its own power.
Melts in Your Bag, Not in Your Hand
Source Institutions
In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
Heavy or Light
Source Institutions
In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.
Apartment Buildings and More
Source Institutions
In this engineering activity, young learners investigate multi-level buildings.
Exploring Properties: Surface Area
Source Institutions
This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
Exploring the Nanoworld with LEGO Bricks: Structure-Property Relationships at the Nanoscale
Source Institutions
In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.
Heavy Air
Source Institutions
In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
Pickle Lab
Source Institutions
In this online activity, learners experience the thrill of pickle making, and explore how a cucumber becomes a pickle.
Balloon Drive
Source Institutions
In this challenge, learners make a helium balloon hover in one spot and then move it through an obstacle course using air currents.
Headphone Helper
Source Institutions
In this design challenge activity, learners add headphones to a previously built instrument (see "Build a Band" activity) to make it easier to hear.
