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.
Our Sense of Sight: Color Vision
Source Institutions
In this activity, learners investigate color vision as well as plan and conduct their own experiments.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.
Adherence to HIV Treatment
Source Institutions
In this activity, learners simulate taking HIV antiretroviral drugs by using Tic Tac mints and Kool-Aid packets.
Smelly Balloons
Source Institutions
In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.
Sound Dampeners
Source Institutions
In this activity, learners will experiment with water- and air-filled balloons as a way of dampening sound before it reaches their ears.
Starting Your Container Garden
Source Institutions
This guide outlines how to plant a garden even if you don't have a yard!
Invisible Sunblock
Source Institutions
In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.
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.
Our Sense of Touch: Two-Point Discrimination
Source Institutions
In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.
Bone Stress
Source Institutions
In this optics activity, learners examine how polarized light can reveal stress patterns in clear plastic.
Personal Fan
Source Institutions
Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.
Digestive System: A Kinesthetic Lesson
Source Institutions
In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.
Smooth Operator
Source Institutions
In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.
Chemical Methods of Control
Source Institutions
In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.
How Do Antacids Work?
Source Institutions
You just ate a big meal and feel heartburn coming on. You take an antacid and feel better. Why? Heartburn is caused by stomach juice (an acid) burning the esophagus.
Burn a Peanut
Source Institutions
In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.
Pick the Risk: The Polygenic Pedigree Challenge
Source Institutions
In this activity, learners are challenged to track and record the passage of colored pom poms (representing genes) through generations of a family using a pedigree.
Milk Makes Me Sick: Exploration of Lactose Intolerance
Source Institutions
Why does milk make some people sick? In this activity learners explore this question and explore the chemistry of milk, and our bodies!
Glitter Slime
Source Institutions
In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.
