Teaching about Diel Temperature Variation

Reebops are cute, marshmallow-based creatures that can be used to teach inheritance. Beginning biologists draw strips of paper that represent chromosomes from two envelopes, one for the father, and one for the mother. Each parent...

Not everything you want to teach about invertebrates is included in this PowerPoint, but everything you may want to teach about fish is. Details, details, details! After a brief introduction to phylum Chordata, junior icthyologists learn...

Learn how genetic variation occurs within prokaryotes through transformation, transduction, and conjugation. The instructor then explains how sexual reproduction in eukaryotes can lead to crossing over, random assortment, and random...

Make sure your unit on trait variation causes a sensation! Take an in-depth look at standard LS3B, an important component of the Next Generation Science Standards. The narrator discusses methods of delivering the standard to younger...

Why do we sweat? Scholars analyze data about body temperature, sweating, and other factors to better understand sweating. They note the changes after drinking ice water to sweating, skin temperature, and body temperature. Analysis...

Ever have a tire or basketball that has no leaks go flat? The lesson starts with that scenario and scholars use a simulation on the computer to learn about three gas laws. The next day, hands-on experiments reinforce the same concepts. 

Energy has many forms ... but very few sources! How do we present this to young scientists? Explore the Definitions of Energy, PS3A, in a video about the Next Generation Science Standards. The narrator keeps it simple by relating each...

Variety truly is the spice of life. A video explores how plants have both chlorophyll a and b and the benefits of possessing both, how varying molecules allows for winter wheat, how possessing the heterozygous combination of sickle-cell...

Why do some smells, like popcorn, linger when others seem to vanish as quickly as they arrive? Learners think through that concept then complete an online simulation to determine if temperature and/or mass affect diffusion. Next, pupils...

Tasmanian devils are scavengers who eat dead animals including the bones and fur. A video begins with cancer in Tasmanian devils to demonstrate the importance of genetic variation. Then examples such as the black-footed ferret and AIDS...
