Take a deep dive into Oregon's ecosystems, plants, and changes from the past to the future. Many hands-on activities in an environmental science unit delight scholars, including creating a field guide for a local park. The in-depth study...

Young ecologists investigate some of the many ways that human activities adversely affect the environment. After identifying the main types of pollution (air, water, soil), 3rd graders fill in a Venn Diagram by pasting cut-out pictures...

Third graders relate that the quality of their drinking water is subject to the condition of the environment and water found in streams and creeks in their community. They track the travel of a wad of paper from a student's desk to a...

Venus fly traps photosynthesize and consume insects because the soil they live in does not provide enough nutrients. Scholars analyze historical scientific experiments to learn how scientists discovered photosynthesis. From their...

Second graders examine the six nutrients humans need to maintain good heath. In this ecosystem lesson, 2nd graders learn about how plants grow and compare how humans need nutrients from plants to how plants need nutrients from the soil....

Just as rocks move through the rock cycle, your giddy geologists will move descriptions around until they are all in the correct category. After cutting out several types of rock movement, learners determine whether the action is...

Oceans absorb half of the carbon dioxide and 80 percent of the greenhouse gases released into the atmosphere. Scholars learn how and why the oceans store heat more effectively than land and how they help mitigate global warming. Pupils...

Fifth graders brainstorm the relationship between trees and humans to determine how humans benefit from trees and how they benefit from us. They discuss oxygen/carbon dioxide exchange, soil stablization, animal habitat, shade, medicine...

As an example of nature's water filtering system, young ecologists conduct an experiment in the lab. They construct a funnel out of a plastic bottle, fill it with specified layers of materials that simulate layers of soil, then run muddy...

Lead your class to construct a solar still on campus to demonstrate how water can be extracted from the soil. The power of solar energy is emphasized, as is the concept of how capillary water can be recovered and purified by using a...

Focusing on the quality of our water sources, these slides are full of information about the aspects of our soil and groundwater that may affect pollution.  The leaching of pollutants and their impact on health is explained. ...

Apply the principles of geology to a series of collaborative, hands-on class activities. Young earth scientists learn more about igneous, metamorphic, and sedentary rocks before classifying and weathering rocks that they find....

Take your science class on a hypothetical field trip to Mars with an engaging astronomy lesson. After first learning about NASA's Mars rover missions, young scientists plan their own scientific investigations of Earth's...

Science learners discover that scientific advancements come in increments. Beginning as an idea, changes and developments are influenced by available resources and current societal values. As an example, pupils examine the conclusions...

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Is a deer an herbivore? What about a spider? Experiment with the food chain in an interactive science experiment. After listing the herbivores from a selection of animals, third and fourth graders compare the skulls and teeth of...

It's hard to imagine that anything was missed on this five-page list of science roots, prefixes, and suffixes! Listed in alphabetical order, all are included in a single, two-column list. This may be especially useful for advanced...

Both GPS and GIS are now used regularly in agricultural careers. Explore the new technologies that require higher education for those interested in agri-science careers. Upper graders examine how agriculturalists use new technologies by...

Get your class out in the environment for hands on math activities. In this wetlands instructional activity, learners transplant native plants, calculate how much soil is needed, and perform math activities based on this experience. They...

The nitrogen cycle is the focus of a well-designed science lesson. In it, learners see that plants and animals produce waste products and decompose after death. Many of the waste products include nitrogen which is absobed by other...

What a great way to start a recycling lesson! Introduce your students to the dung beetle! They will get a kick out of "nature's perfect recycler," when they learn about the  scarab beetle's way of life: eating dung and rotting...

This slide show progresses through a comprehensive review of the grounding principles of earth science. Get down and dirty with the details of fossil fuels! Help your geologists to have a rock solid understanding of the rock cycle. The...

With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...
