Metal Reactions
Source Institutions
This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.

Algae in Excess
Source Institutions
Plants need nutrients to grow. This is why we apply fertilizers to grass and food crops. In this activity, learners will explore how fertilizers can affect lakes and other bodies of water.
Bee Talk
Source Institutions
In this activity, learners smell bottles containing bee pheromone molecules (or herb/spice extracts as a substitute). Bees release these molecules to send messages to each other.
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.

The Missing Link
Source Institutions
In this activity, learners collect, analyze, and interpret information about objects in order to classify them into a cladogram. Use this activity to talk about how scientists classify things.

Building a Basic Series Circuit
Source Institutions
This activity was designed for blind learners, but all types of learners can use it to build and examine a basic electrical circuit.

Bicycle-Wheel Gyro
Source Institutions
In this activity, a spinning bicycle wheel resists efforts to tilt it and point the axle in a new direction.

Water Body Salinities II
Source Institutions
In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

Toxic Popcorn Design Challenge
Source Institutions
In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

Rearing Monarchs
Source Institutions
As a long-term project, you can rear monarch butterflies at home or in a classroom.

Giant Chromosomes: Fruit Fly DNA and You
Source Institutions
Many of the genetic sequences found in the fruit fly genome are similar to those found in humans.

Power To Go
Source Institutions
Learners observe an electrochemical cell constructed from a small jar containing zinc and copper strips immersed in separate solutions. The strips are connected to a motor that turns a small fan.

Envirolopes
Source Institutions
In this outdoor activity and observation game, learners hunt for a variety of textures, colors, odors and evidence of organisms in the activity site.

Observing Insects at Night
Source Institutions
In this activity, learners set up a night time insect observation station with a light and sheet.

Water Quality and pH Levels in Aquatic Ecosystems
Source Institutions
In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

Evolutionstechnik or Selection and Variation in the Egyptian Origami Bird (Avis papyrus)
Source Institutions
In order to examine the random nature of mutations and natural selection, learners "breed" clutches of Egyptian Origami Birds (Avis papyrus) using random number generators (dice and coins) to mutate s

Over the Hill
Source Institutions
In this physics activity, learners construct a small-scale version of a classic carnival game.

Convection Current
Source Institutions
In this activity, learners make their own heat waves in an aquarium.

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.
