DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Iron for Breakfast
Source Institutions
Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?
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.
Root Beer Float
Source Institutions
In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.
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.
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.
Inside DNA
Source Institutions
In this activity (on pages 34-39), learners make a fairly detailed model of DNA using licorice and gumdrops.
Amphibian Skin
Source Institutions
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
Making Connections: What You Can Do To Help Stop Global Climate Change
Source Institutions
In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.
Testing for Life's Molecules
Source Institutions
In this activity, learners conduct tests for proteins, glucose, and starch.
DNA Nanotechnology
Source Institutions
In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
Mapping Sea Level Rise
Source Institutions
In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.
What Molecules Make the Holes in Bread?
Source Institutions
In this activity, learners will discover why there are holes in bread.
Natural Indicators
Source Institutions
Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).
Pickle-oh!: Musical Pickle Instrument
Source Institutions
What's a Pickle-Oh? Two pieces of pickle on a stick are connected to a Pico Cricket (micro controller). When you slide the pickles apart the note changes.
Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
Pom Pom Potential
Source Institutions
In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.
How Does Water Climb a Tree?
Source Institutions
In this activity, learners conduct an experiment to explore how water flows up from a tree's roots to its leafy crown.
Fuel for Living Things
Source Institutions
In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.
Neural Network Signals
Source Institutions
In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.
