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.
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).
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
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.
Rotating Light
Source Institutions
In this activity, learners explore what happens when polarized white light passes through a sugar solution.
Water Body Salinities I
Source Institutions
In this activity, learners investigate the different salinity levels of oceans, rivers and estuaries.
lambda DNA Fingerprinting Simulation
Source Institutions
The purpose of this lab activity is to demonstrate (through simulation) how DNA fingerprinting (or DNA profiling) might be used to solve a crime.
Fragile Waters
Source Institutions
In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.
Bready Bubble Balloon
Source Institutions
Learners discover the bubble power of living cells in this multi-hour experiment with baker's yeast. Learners make a living yeast/water solution in a bottle, and add table sugar to feed the yeast.
Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Water Clean-up
Source Institutions
This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.
How Plants Grow
Source Institutions
In this biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.
What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
Odors Aloft
Source Institutions
Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.
Do the Mystery Samples Contain Life?
Source Institutions
In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.
Leaves: Extracting Pigments
Source Institutions
In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.
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.
Amazon Water Cycle Roleplay
Source Institutions
In this creative roleplay activity, learners will explore the various processes of the water cycle using movement, sound, and props to aid in comprehension.
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
