The Old White Sheet Trick: Light and Insect Behavior
Source Institutions
In this outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.
What is Light?
Source Institutions
In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.
See the Light
Source Institutions
Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.
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.
Do Plants Need Light?
Source Institutions
In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.
Film Canister Farming
Source Institutions
In this hands-on botany activity, learners sprout vegetables in film canisters.
Easy PEAsy Seed Germination
Source Institutions
In this activity, learners determine the necessary conditions for pea seed germination.
Illuminating Luminescence
Source Institutions
In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.
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.
Moldy Jell-O
Source Institutions
In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
Sensory Hi-Lo Hunt
Source Institutions
In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.
Photosynthetic Pictures Are Worth More Than a Thousand Words
Source Institutions
This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.
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.
Lighting Up Celery Stalks
Source Institutions
In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla
Round, Light and Hollow
Source Institutions
In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.
Decomposition Column
Source Institutions
In this activity, learners turn empty 2-liter bottles into a see-through compost container.
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.
Tools of Magnification
Source Institutions
In this activity related to microbes, learners use water drops and hand lenses to begin the exploration of magnification. This activity also introduces learners to the microscope.
