How Do New Species Form?

This doesn't have to be used as a guided notes activity because the questions are thought-provoking and applicable to any biology class that is learning about the origin of species. Pupils write out answers to questions about speciation,...

AP biology buffs define vocabulary terms and answer critical-thinking questions about evolutionary trends. They compare macroevolution to microevolution, differentiate ploidy possibilities, explain isolation barriers, and more....

The best part of learning about equilibrium is that nothing changes. Young chemists observe four demonstrations during this lesson: equilibrium in a saturated solution, equilibrium with an acid-base indicator, equilibrium with cobalt...

Young scholars investigate the effects of adding or removing a reactant or a product on chemical equilibrium. In this equilibrium lesson plan, students add or remove ions to solutions to determine the effects on equilibrium. They make...

Investigate the Hardy-Weinberg Principle to explain genetic equilibrium. The 10th lesson plan of a series of 12 is a laboratory exploration of genetic equilibrium. Your classes use a mixture of beans to model allele and genotype...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Students experiment with traits. In this Science lesson, students test the strength of beetles using M&M candies in lieu of the insects. Students use the Hardy-Weinberg Equation to calculate possible offspring traits of further...

Examples of natural selection over time will make the concept of evolution more clear to your students. This presentation is short but summarizes the mechanisms of isolation and selection clearly.  This presentation would be useful to...

Combine agriculture and an increase in population density in sub-Saharan Africa and what do you get? Malaria! Young immunologists explore malaria's deadly rise to fame in a video. The narrator discusses its beginnings as a hitchhiking...

Animal testing: cruel and inhumane, or innovative and life-saving? Scholars explore the topic and form their own opinions with help from the highly informative website. Pupils read a comprehensive overview of the topic, including...
