Limiting Factors/ Evolution Game

Darwin explained the connection between species of finches 150 years before scientists understood DNA. Technology and progressing science proved he was right, yet many struggle to understand how natural selection happens. Scholars use...

You don't have to be a scientist or even out of high school to contribute to scientific research. In the 12th lesson in the series of 21, scholars use this opportunity to add to the growing body of scientific knowledge and consider the...

Scientists believe red hair and pale skin evolved in northern Europe because it helped humans synthesize vitamin D easier than those with more melanin in their skin. Viewers explore many interesting facets of evolution in a...

A short video offers a simple, yet engaging, explanation of the theory of evolution using amoebas as an example. The narrator uses the example of the evolution of dog breeds as an example of how humans can influence the course of change.

Sometimes things are just left over. An informative video in the JFR Science series highlights limiting and excess reactants in a chemical reaction. It explains the process of solving stoichiometry problems with limiting reactants.

As the great and hilarious Tim Minchin once said, "Science is simply the word we use to describe a method of organizing our curiosity." Science is more than just a guess; it is based on questions, observations, and evidence. High...

Discuss the differences in dialogue and debate when considering a controversial topic. Your class can work in small groups to complete a guided discussion of this controversial topic and then participate in a simulation of the Scopes...

Evolution can be supported by the lines of evidence which are presented in this resource. Recognize these lines: fossil evidence, homologies, distribution in time and space, and evidence by example.

Use the Franklin Institute's exhibition "An Inquirer's Guide to the Universe" to have students research ideas for a science fiction story. After completing their research, writers will compose science fiction stories that incorporate...

Time to test the limits! Young scientists make limiting reagent calculations and test their math using a virtual lab simulation. Using their knowledge of ionic compounds, they determine the limiting reagents and the excess compounds.
