Mother Nature's Gravel Company is open for business! The unit includes four lessons covering weathering and erosion. Experiments are simple to complete and young geologists compare notes to see who makes the biggest ice...

This four-page handout would work great as a reading guide or note-taking resource for teens learning about ATP, photosynthesis, the key scientists in the realm of photosynthesis, and more. It is designed to accompany a certain textbook,...

Learners understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Students investigate the function and purpose of seed dispersal. In this garden lesson, students examine the importance of wind in the plant cycle. Students construct a flying seed model from an attached design and discuss if it can be...

Second graders observe the changes that water has when there is a change in a state of matter. For this lesson they observe the results of applying heat to water with the end result of conversion to a gas.

Second graders discuss the geologic rock cycle and work with their group to simulate creating a sedimentary rock. They conduct an experiment that demonstrates the sedimentary process and draw the steps of the rock cycle.

Students measure humidity in the classroom. In this weather activity, students use a psychrometer to measure the humidity in the classroom. Students complete a lab packet.

In this migration and hibernation worksheet, students read a 2 page informational excerpt about animals who adapt to changing seasons by migrating or hibernating. They then use the information they learned to answer the 15 questions on...

In this pollution worksheet, students read about thermal pollution and how hot water affects wildlife. Then students complete 1 short answer question.

Pupils explain the importance of water in our daily lives. In this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Learners identify and define the main components of the hydrosphere and the ways in which they interact with one another. They explore how changes in Earth's surface materials affect components of the hydrosphere and evaluate the effect...

High schoolers explore the concept of global warming. In this climate change lesson, students explore the provided links to PBS NOW sources and research the greenhouse effect and the effects of global warming. High schoolers support...

Students explore Earth's seasons using an interactive website. In this earth science instructional activity, students watch video segments and explain Earth's seasonal milestones. They discuss the factors that causes seasonal changes.

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

Students experience the effects of pollution and erosion on a model of a watershed and explore ways to change the outcome.

Students examine the importance of each season to the life cycle of an apple tree. In small groups, they create a four-season display illustrating the life cycle of an apple tree along with a written description of each season.

Third graders experiment with beakers of water and balloons to measure the volume of the gas in the balloon. They determine ways to change the volume of air in the balloon which changes its size but not its physical state. By heating the...

Second graders examine the life cycle by observing tadpoles. After reading the book, Tadpole Diary, they draw the stages of tadpole development and write sentences about what they think is happening.

Students construct and observe a model of two different types of wetlands. In this wetlands instructional activity, students create a model of a wetland with constant drainage and a wetland that maintains a well-saturated soil. Students...

First graders investigate composting. In this biology lesson, 1st graders identify ways to use garbage as fertilizer. Students examine soil and compost matter as well as the role of worms in the dirt.

Students develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students study trees and their growth.  In this investigative instructional activity students work in groups to reconstruct a 50 year climatic history using a simulated tree ring. 

Students collect rocks, identify them, classify them, investigate their properties, and more. In this rocks lesson plan, students also experiment with soil and erosion and weather.

Students investigate what causes the heat on Earth.  In this Earth heating lesson, students experiment with different heat sources and determine where the Earth gathers the most heat.  Students explore vocabulary words...
