Cleaning with Dirt
Source Institutions
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

Neurotransmitters Contain Chemicals
Source Institutions
In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

Lean, Mean Information Machine: Using a Simple Model to Learn about Chromosomal DNA
Source Institutions
Learners observe a model of a cell and its chromosomal DNA made from a plastic egg and dental floss. Use this model to illustrate how much DNA is held in one cell.

Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Digestion
Source Institutions
In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

Crossing the Synaptic Gap
Source Institutions
In this neuroscience activity, learners conduct a simulation to demonstrate how multiple incoming signals influence the action of neurons.

Modeling Day and Night
Source Institutions
In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

The Geophysical Light/Dark Cycle
Source Institutions
This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

Latent Prints
Source Institutions
In this activity, learners examine fingerprints. Learners leave a hidden print on a surface and then make their own print detecting powder from graphite (found in pencils).

Baroreceptor Reflex Role Play
Source Institutions
In this activity about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

DNA Extraction
Source Institutions
In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

How Do Viruses Recognize a Target Cell?
Source Institutions
This activity demonstrates the specificity of viral vectors for target cells in gene therapy delivery methods using two approaches: 1) STYROFOAM® models demonstrate viral ligand binding to receptor pr

Measuring Your Breathing Frequency at Rest
Source Institutions
In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

Skin Deep
Source Institutions
In this activity, learners explore how to protect their skin while applying pesticides to plants.

Is That DNA in My Food?
Source Institutions
In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.

Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.

Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.

Animal & Plant Cell Slides
Source Institutions
In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.
