Photosynthetic Pictures Are Worth More Than a Thousand Words
Source Institutions
This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
Portable Potable Pressure
Source Institutions
In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.
What's the Matter
Source Institutions
In this activity, learners identify different classes of matter based on physical properties.
String Thing
Source Institutions
String Thing is an interactive online game in which learners change a virtual string's tension, length, and gauge to create different musical pitches.
Resonant Rings
Source Institutions
Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.
Exploring the Nanoworld with LEGO Bricks: Structures and Their Construction at the Nanoscale
Source Institutions
In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
Building with Wonderful Junk
Source Institutions
In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.
AM in the PM
Source Institutions
In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.
Mini Vortex
Source Institutions
In this activity, learners will build an air cannon out of simple materials you can find around the house. Although air is invisible to the eye, it is not by any means empty space!
Measure the Pressure II: The "Dry" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Make a Balance / Scale
Source Institutions
In this activity, learners create a kind of balance device using a wire coat hanger, some string, and paper cups.
Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.
Shadow Puppets
Source Institutions
In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.
Airplane Wing Investigation
Source Institutions
This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.
Edible Ink
Source Institutions
In this chemistry activity (page 6 of the PDF), learners observe a chemical change. Learners write and reveal a secret message using edible ink.
Light and Dark
Source Institutions
Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.
How Sweet It Is
Source Institutions
In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea
Heavy Metal
Source Institutions
In this activity (on pages 25-31 of PDF), learners soak sponges with different amounts of plaster of paris to simulate different levels of calcification in bone formation.
Shrinking Cups
Source Institutions
This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.
Arrows
Source Institutions
In this activity, learners surprise their eyes with an optical illusion involving arrows made out of pipe cleaners.
