How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases...

How will a scale factor affect a figure—negatively? Using a grid, the narrator of an engaging video performs a dilation with a negative scale factor. The presenter compares a positive scale factor with a negative scale factor to explain...

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

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

Students complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...

What kind of experiment can your class do to how observe the environment effects on organisms? Groups design and conduct lab experiments to learn about the effects of the environment on aquatic organisms. Based upon knowledge gained...

A very timely lesson looks at the social and political factors that affect the spread of disease. Using the 1918 Influenza Pandemic as a case study, pupils research factors that influenced the spread of the disease, including the role of...

Students relate heart rate and development to environmental conditions through experiment. In cooperative groups, students record the heart rate in developing zebra fish. Groups create a standard curve to predict the temperature at...

Students identify the abiotic factors that influence a river or stream and the organisms that live in it. They measure several abiotic and biotic parameters to gauge water quality. Students examine the biotic environment by identifying...

How does a population's habitat determine the size of that population? Teach learners about carrying capacity and limiting factors with an engaging roleplay activity. Class members pose as a colony of penguins who must gather food amidst...

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...

Students assess the factors affecting animal populations. Working in groups they define specific vocabulary terms and complete several activities from "Project Wild."

How can non-polar molecules be attracted to one another? Introduce the phenomenon of London dispersion forces to young chemists through an entertaining interactive. Pupils choose from a variety of molecular shape combinations, then pull...

During this game, kids become migratory shorebirds and fly among wintering, nesting, and stopover habitats. If they do not arrive at a suitable habitat on time, they do not survive. Catastrophic events are periodically introduced that...

The clear cartoon style slides in this presentation contain details that affect population growth. Natural disasters and other external factors are listed as density independent factors, and density dependent factors, such as competition...

Collaborators sort a set of cards into biotic and abiotic categories. Then, as a class, they discuss their work and relate each of the abiotic components to climate change. Finally, they form a web of components by connecting those that...

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Elementary ecologists pretend to be migratory hummingbirds. They fly between wintering and nesting grounds, trying to reach a habitat haven. In a musical-chair fashion, some birds will miss out, and are removed from the game. To further...

Your learners will take key economic concepts, such as identifying needs versus wants and the four factors of production, and design a video to explain their topic choice to the class. Rather than have one person in charge of dispensing...

Students study the environmental factors that affect food systems and choices. In this food systems and health lesson, students study global and national information about obesity. Students study photos and captions about the topic....

What causes people to move from one place, one city, or one country to another? Using the provided migration questionnaire, learners interview family members about the factors that cause them to be pushed from an area or pulled to...
