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.
Trading Places: Redox Reactions
Source Institutions
Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.
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.
Forwards and Backwards: pH and Indicators
Source Institutions
Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).
Plugged in to CO2
Source Institutions
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.
The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.
The Recycling Conservation Calculator
Source Institutions
In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.
You Can't Take It With You
Source Institutions
This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
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.
Glow Up
Source Institutions
In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.
Make a Terrarium
Source Institutions
In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.
Your Energy Needs
Source Institutions
In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Make Your Own Batteries!
Source Institutions
This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.
Power Up!
Source Institutions
In this online game, learners must purchase power plants for their city.
The Carbon Cycle and its Role in Climate Change: Activity 1
Source Institutions
In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.
Nutritional Challenges
Source Institutions
In this nutrition activity (page 26 of PDF), learners consider the nutritional needs of people with specific dietary requirements, such as athletes, persons with diabetes and vegetarians, and create a
