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.
Temperature vs. Height: Soda Geyser Series #6
Source Institutions
In this activity, learners conduct a controlled experiment to examine how temperature will affect the height of a soda geyser.
The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.
Rocket Wind Tunnel
Source Institutions
In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.
Fizzy Fun
Source Institutions
In this activity, learners test what happens when they put baking power on different frozen liquids.
Number of Mentos vs. Height: Soda Geyser Series #5
Source Institutions
In this activity, learners conduct a controlled experiment to examine how many Mentos are needed to make the tallest possible soda geyser.
Soda Brand vs. Height Experiment: Soda Geyser Series #4
Source Institutions
In this activity, learners conduct a controlled experiment to examine which brand of soda makes the best (highest) soda geyser.
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.
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.
