Discovering Rainforest Locations
Source Institutions
In this activity, learners will examine various world data maps to combine the information and predict which areas could be tropical rainforests.

As The Stomach Churns
Source Institutions
In this chemistry activity, learners fill two test tubes with a solution of "artificial stomach fluid," consisting of hydrochloric acid in the same concentration as in human stomachs, some soap to cre

Making Music in Nature
Source Institutions
In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

Owl Pellets
Source Institutions
In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

Scavenger Hunt
Source Institutions
An outdoor scavenger hunt helps learners consider the theme of "What Is Life?" Learners explore what living organisms are, including how organisms meet basic needs of food, shelter and water to surviv

What is a Fossil?
Source Institutions
In this activity about dinosaurs, learners explore how and why fossils form. First, learners are introduced to dinosaur fossils by reading the book "Bones, Bones, Dinosaur Bones" by Byron Barton.

Stiff Bones, Bendy Bones
Source Institutions
Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.

Germ Tag
Source Institutions
In this version of tag, a large group of learners model how the body fights infection. Learners act as germs, as lymphocytes, and as the body's cells threatened by germs.

Seashell Journal
Source Institutions
In this activity, learners make homemade journals featuring seashell rubbings. First, learners transfer the texture of a seashell onto a piece of paper using a crayon.

Building Bingo
Source Institutions
In this on site "field trip" activity (located on pages 6-9 of PDF), learners get hands-on experience identifying building materials by playing "Building Bingo".

How We Know What The Dinosaurs Looked Like: How Fossils Were Formed
Source Institutions
In this activity (p.7-8 of PDF), learners examine fossil formation.

What's In Your Breath?
Source Institutions
In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

Antigen-Antibody Testing: A Visual Simulation or Virtual Reality
Source Institutions
In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.

Water Striders
Source Institutions
In this outdoor activity/field trip, learners catch and observe water striders to explore their movement and feeding behaviors.

Parabolas: It's All Done with Mirrors
Source Institutions
In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

Vegetable Revival
Source Institutions
In this activity, learners use food scraps from the kitchen to grow new vegetables.

Making a Battery from a Potato
Source Institutions
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
The Earth's Timeline
Source Institutions
In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

Natural Buffers
Source Institutions
Learners use a universal indicator to test the amount of sodium hydroxide needed to change the pH of plain water compared with the amount needed to change the pH of gelatin.
Moving Pictures
Source Institutions
In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.
