Laser Jello
Source Institutions
In this activity, learners use gelatin as a lens to investigate the properties of laser light.
Oil Spot Photometer
Source Institutions
In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
Super Gelatin
Source Institutions
Can gelatin (like Jell-O ®) change the speed of light?
Pupil to Pupil
Source Institutions
In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.
Illuminations on Rates of Reactions
Source Institutions
In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
Inverse Functions: Pennies, Pressure, Temperature, and Light
Source Institutions
The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.
Mirror, Mirror
Source Institutions
In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.
The Senses of "Unknown Creatures"
Source Institutions
In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
How Our Environment Affects Color Vision
Source Institutions
In this lab (Activity #1 on page), learners explore how we see color.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Hot Air
Source Institutions
In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
Wintergreen
Source Institutions
In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.
Tasty Buds
Source Institutions
In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.
Mussel Your Way Through Photosynthesis
Source Institutions
Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.
Biological Succession in a Microecosystem
Source Institutions
This laboratory activity helps learners understand the concept of biological succession by simulating the process in a microenvironment with various protozoans.
Properties of Dust
Source Institutions
In this activity, learners carry out a scientific investigation of dust in their classroom. Learners produce an analysis on graph paper of the dust they collect over the course of a few days.
Disappearing Crystals
Source Institutions
Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.
Earth's Energy Cycle: Albedo
Source Institutions
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.
