Learners are given some components of an experiment, where they are able to identify and fill in missing parts, such as hypothesis, conclusion, results, etc. They form a hypothesis given general scientific facts. Students apply the...

Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...

After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...

Students analyze the impact of climate variability and change utilizing a broad span of topics over a wide range of grade levels. This three lesson unit is easily adapted for the various instructional levels listed.

Future scientists are introduced to the chemical consequences of burning fossil fuels, learning that fossil fuel combustion leads to the formation of oxides of three nonmetals: carbon, nitrogen, and sulfur, all of which end up in the...

Students discover the processes that occur during mitosis and what makes each phase different and distinct from the others as well as how each contribute to the overall process of mitosis by looking at onion root tips under a microscope.

High schoolers determine the normal behavior of California blackworms. They determine how various concentrations of assigned toxicants affect the worm's behavior. Students are introduced to testing of potential toxicants, an important...

Students examine data to investigate the impact of lead shot pellets on waterfowl populations. They graph their findings and discover how lead in ingested by birds and poisons them. As an extension, students research legislation and...

Students explore how sewer systems can contribute to water pollution and perform an experiment to see how well a water purification technique can protect against water-born microbial illnesses. They compare the bacterial growth from...

Young scholars investigate plants and compare them to the purple loose strife. As they observe the plants they predict possible impacts on plant populations based on their observations. They work in groups and present their findings to...

A video and laboratory investigation are highlights to this lesson plan on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon...

Students explore agriculture by conducting a technology conversation in class. For this food system lesson, students identify the path of food from farm to plate and view a virtual farm on the Internet. Students complete a farming...

Students study organisms found in Class Insecta. They examine the different adaptations these organisms have developed over time to survive and prosper in their respective habitats. They research the origin of the names of several orders...

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...

And now moving on to the next story. The last of five lessons in Unit 1: The Big Climate Change Experiment requires groups to create a script for a news segment on climate change. They either make a video of their story or conduct a live...

Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Young scholars explore the climate and food sources of Ghana.  In this lesson on climate students view diagrams of global convection and complete a convection experiment.

Young scholars are introduced to the causes of plate movements and the hazards they present. They plot the location of 50 earthquakes and 50 volcanic eruptions on a map and explore the relationships between plate tectonics, earthquakes,...

Learners examine the consequences of cutting down large amounts of forests throughout the world. In groups, they use the internet to complete a module taking them on a tour through different temperate forests. To end the lesson plan,...

Students explore all the facets about weather and analyze how weather and climate are connected through time. They consider how weather changes and the effects of weather on the present state of the Earth's climate. Alterations to our...

Students explain how melting glaciers affect global warming. In this earth science activity, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students explain the impact of glacial melting to global climate change. In this environmental science lesson plan, students design an experiment to investigate the effect of salinity change to melting glaciers. They share their results...

Students will examine how floods work and why they can cause so much damage and destruction. They use a stream table to observe the processes that lead to flooding and the effects of floods on human-made structures. Includes a guide to...

Twelfth graders read a variety of science fiction short stories. Using the text, they identify the components that make it science fiction and a well written piece of literature. They record their observations and share them with the...
