Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
Antigen-Antibody Testing: A Visual Simulation or Virtual Reality
Source Institutions
In this biology activity, learners use plastic pipettes to cut wells into the solid gel layer of agar in petri dishes and place solutions of simulated antigen and antibody preparations into the wells.
Waves and Tides
Source Institutions
In this 7-10 day investigation, learners develop an understanding of waves and tides and their motion through discussion, demonstration, and hands-on activities.
Food Forensics: A Case of Mistaken Identity
Source Institutions
This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Wind Power: Creating a Wind Generator
Source Institutions
This lesson challenges groups of learners to design and construct a wind generator with the most electrical output.
Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
Electricity: Fruit Batteries
Source Institutions
In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.
Photolithography
Source Institutions
In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.
Outbreak!: Investigating Epidemics
Source Institutions
A group of learners simulates the spread of disease by trading slips of paper, one set of which has been treated with a baking soda solution.
