Taster/Non-taster Lab Activity

Some background information about density and Newton's Laws of gravitation and motion assist pupils in the following experiment. The procedure will help them further their understanding of gravity, pendulums, and a drop-ball experiment....

Do golf courses affect the water organisms in nearby streams and ponds? Small groups collect samples of water upstream and downstream from a golf course and analyze the macroinvertebrates found and the stream index values of...

Two fish appear different, but how do scientists determine their genotypes? Scholars practice performing test crosses to determine the genotypes of fish given their phenotypes. They answer in-depth comprehension questions and complete...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

The United States is the world's largest producer of biofuel. During an in-class investigation, young scientists produce their own biodiesel. They burn a sample of it to determine the heat of combustion. Then they discuss the...

Explore the center of gravity with your science class as they create a deadfall trap with common materials. They research the concepts of energy conservation and gravitational force before dividing into small groups to create a model of...

While camping on the Appalachian Trail, a storm dampens all the fire wood and you must design a chemical reaction to heat your meal. In this activity, students design an experiment in the virtual lab to determine the heat of reaction for...

Students use kinetics to interpret raw experimental data to determine the mechanism of ozone destruction. In this pen and pencil activity, students are given data obtained from laboratory experiments to study the ozone depletion reaction.

Gregor Mendel's work revolutionized agriculture from an art to a science. Explore Mendel's work with an interactive lesson that includes animations, video, and practice problems. The instruction describes the early discoveries that...

Examine the benefits of chemical defense mechanisms. Organisms in oceans use chemicals to ward off predators. Duplicate this adaptation using a hands-on experiment in which you ward off your predators (your pupils) with some...
