Is the sky falling? Learners use a simulator to modify the mass and velocity of asteroids and collect data on how they influence the diameter and depth of the impact crater. They use their results to draw conclusions and make predictions...

Let the pictures do the talking. Children tell their stories using provided guidelines for a photo essay exhibit. Discussion questions and checklist materials help pupils brainstorm and create photo essays to help inspire social change.

Scientists study how pollution occurs in hopes of minimizing its effects. A quick activity shows how point and non-point source pollution enters groundwater and aquifers. Learners mimic the phenomenon with models that show how rain...

Rainwater doesn't stay where it falls. Learners use modeling to demonstrate how rainwater disperses once it hits the ground. The activity includes an investigation of the height of the water table in an aquifer and how it is affected by...

Bring the water cycle to life with in the classroom. Young scientists use household materials to create and monitor a water cycle model. They record changes in the water levels and make observations of where and how fast precipitation...

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

Dive into a lesson on marine ecosystem interactions. Individuals learn about and devise a marine food web. The resource provides organism cards and pupils use article resources to discover interactions before modeling them in a food web.

Bees get all the attention, but so many more creatures contribute to pollination. Scientists explore the role of pollinators as they learn about the parts of a flower and how it reproduces. They discover how plants rely on many different...

Everyone should take an interest in the fate of wild cats. A thorough lesson explores the habitat changes of native North American wild cats and asks learners to make connections to human development. They consider the implications of...

Observing plant succession doesn't have to be a decade long process. A hands-on lesson has groups study succession over a designated space. Learners use their observation skills to record differences in plant and soil characteristics in...

Bats are a misunderstood species. Pupils learn about the characteristics of bats in a three-part lesson. They begin by examining the adaptations of different types of bats, then explore the misconceptions humans have about the species....

Less than one percent of the water on Earth is usable in people's homes. As pupils consider this fact, they reflect on their own water usage before designing a survey to collect information on water usage by others. They then analyze...

How prevalent is pollution in the water system? A hands-on activity focuses on one area that is prone to pollution. Learners use game chips to represent clean water and polluted water and complete an activity that demonstrates how...

Natural design is amazing. Young scientists connect the features of a bison to an assortment of everyday items. A bison's tail is an ideal flyswatter, and a pot stores water just like a bison's stomach. The lesson connects the usefulness...

A balanced ecosystem doesn't mean balanced populations. Budding scientists complete a series of activities to learn about the relationship between producers and consumers in an ecosystem. They complete the wildlife conservation...

Mammals have unique interactions with their ecosystems. Using a multi-part lesson, learners research local mammals using recommended websites and use their findings to create their own paper ecosystems including appropriate mammals. They...

Ecosystems are constantly changing whether people notice or not. An inquiry-based lesson examines types of ecosystem changes and how they relate to wildlife conservation. Learners classify changes as succession and disturbance using a...

What do a reptile and an amphibian have in common? A three-part lesson allows scholars to investigate the similarities and differences between the two types of animals by identifying specific body parts. The lesson highlights the...

Out of sight out of mind can be a dangerous habit. Learners investigate the life of food waste after it leaves people's homes and its impact on the environment. They complete a series of three activities that involve building a mini...

All trees are not created equal. A set of three wildlife conservation lessons has learners examine the characteristics of individual trees. They look at the life cycle of the tree using a story and reference a field guide to identify...

It's the attack of the invasive species! Young scientists simulate the behavior of an invasive species with a game-like activity. They assume the roles of native plants, invasive plants, and resources and watch the invasive plant takes...

Scientists use data to learn about species survival—and your classes can too! A set of four lessons guides learners through a process to draw conclusions about the fluctuations in the population of the Hellbender species. They read...

Urban development and habitat retention are often at odds. A three-part lesson examines the pros and cons of forest clearcutting. Learners review data and characteristics of a specific mammal to make conclusions about the effect...

Human impact on watersheds can make or break an ecosystem. Learners use a game to learn about the impact human choices have on water quality and the organisms that depend on it. The activity includes a game board and game cards that tell...
