Laboratory activities encourage evolutionary biology scholars to consider homologous structures as evidence of common ancestry. They learn how to formulate phylogenic trees and that environment influences to genetic variation. Activities...

Students examine abiotic and biotic factors. They define biotic and abiotic, categorize a list of items onto a Venn diagram, label various items from areas on the school grounds as biotic or abiotic, and diagram a magazine picture.

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....

Are there factors that put some individuals at a higher risk for drug addiction than others? Learn more about the risk factors that may make some people more susceptible to addiction, as well as protective factors that help prevent...

Students play a board game with provided cards which help them realize that limiting factors may restrict an organism in its development and productivity and direct evolutionary pathways.

High schoolers discuss how the Hudson River is an ecosystem made up of both biotic and abiotic factors. They view the PowerPoint the Journal Down the Hudson River. Students become aware of where the Hudson River begins and ends, the...

Five questions about the work of biochemist, Oswald Avery, are presented on this worksheet. You will need to find a reading passage, perhaps on the Internet, about his discovery, but it would be a worthwhile search. The assignment brings...

Students determine the physical and chemical factors that affect plant growth. In this biology lesson plan, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.

Young scholars experiment with yeast. In this environmental conditions lesson students test the viability of samples of yeast. Young scholars investigate the effects of environmental conditions on the yeast.

In this ecosystem worksheet, students use a string and make a large circle. Everything in the circle is part of the ecosystem the students will study. They identify everything in their ecosystem and classify their data. They answer 2...

In this mass worksheet, learners determine the number of moles from a given molar mass and volume being sure that they use the correct conversion factors. This worksheet has 12 problems to solve.

Introduce infectious diseases and the epidemiologic triangle. A helpful resource describes the agent, host, and environment from the three vertices as well as the time factor, which is in the middle. Scholars complete a simple...

In this planetary alignments worksheet, students use 2 different methods to find out when planet alignments will occur. They use a three number series and they use least common multiples to find out when Mercury and Venus will align.

Learners identify the factors affecting friction. In this physics lesson, students construct their own rocket car and race them. They graph the average speeds and discuss how lubricants affect friction between rubbing surfaces.

Several factors affect the rate of a chemical reaction including temperature, surface area, and concentration. Using an experimental approach, learners explore the effect concentration has on this rate while maintaining consistency with...

How does gravity affect the life cycle of a butterfly? Learn first-hand what types of investigations astronauts perform in space by following along with one of NASA's experiments. Create butterfly habitats in the classroom with specific...

This is mostly an exploration of race through an interactive website, class readings, and discussion. Individuals take an online quiz about race, they answer questions on a worksheet by visiting another website, and discover that race is...

Students discuss their community's water sources and assess the factors affecting the water availability and quality. They research water disputes around the world and explain common factors among them.

Key to understanding scientific or technical texts is identifying the underlying question the author is attempting to answer. Provide your young scientists with an opportunity to practice identifying these questions and the procedures...

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Learners review the terms and concepts: evolution, selection, biotic, and abiotic factors. They come up with hypotheses about limpet shell types based on what we discuss about intertidal environments. Students use ratios to compare...

In this orbital period worksheet, students solve 2 problems about satellites and their orbits. They determine how many days it takes for two satellites to be in "opposition", they find the least common factor between their orbit periods...

Young scholars will understand the relationship between limiting factors and evolution. They will be able to hypothesize possible evolutionary pathways for modern day organisms.
