In this activity (on pages 23-29), partners use the Plant Traveler Cards, along with a world map and map worksheets, to follow plants such as cassava, chocolate and coffee that grew first in one part

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells using simple materials.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

In this challenge, learners figure out how to make a juice stain disappear.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

This is a classic exercise for visualizing the scale of the Solar System.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

In this activity, learners examine their tongue and taste buds.

In this activity, learners stain fabrics--on purpose!

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

In this activity, learners mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).
