Do the Mystery Samples Contain Life?
Source Institutions
In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

Fruity Electricity
Source Institutions
In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.

Bend a Carrot
Source Institutions
In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

Ship the Chip
Source Institutions
In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

Thymus DNA Extractions
Source Institutions
This laboratory exercise is designed to show learners how DNA can be extracted from a chunk of thymus (sweetbread) or liver.

Inside DNA
Source Institutions
In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.

Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

Amphibian Skin
Source Institutions
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

Web It!
Source Institutions
In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves.

A Dissolving Challenge
Source Institutions
In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.

New Sense about Cents
Source Institutions
In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

Cooking With the Sun
Source Institutions
In this activity, learners build a simple solar oven out of household materials to melt chocolate and marshmallow between graham crackers--known as s'mores.

Temperature vs. Height: Soda Geyser Series #6
Source Institutions
In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.

Gummy Growth
Source Institutions
In this activity related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

Bird Feeder
Source Institutions
In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

Mystery Writing: Write and develop a secret message
Source Institutions
Learners write an invisible message using lemon juice on a piece of paper. They then develop the message by soaking the paper in a dilute iodine solution.

Ice Cream
Source Institutions
In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

Kosher Dill Current: Make Your Own Battery!
Source Institutions
This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

Racing M&M Colors
Source Institutions
Learners design their own experiment to determine which M&M color dissolves the fastest in water.
