Fifth graders observe their plant experiments that they started in a previous lesson and examine the role of decomposers in the nitrogen cycle. Two weeks after they set up a worm terrarium, they analyze any changes they observe, and...

Students view pictures of animals as they complete the metamorphosis from a larva to an adult. In this metamorphosis lesson plan, students view pictures and in the end are able to match pictures of a larva stage to an adult stage in...

Students play a game about the life cycle of a blue crab in order to witness the causes of changes in the crab population and discuss what a resource manager could do to keep a stable crab population. Students then create a game titled...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for...

Students 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. In 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.

Learners measure humidity in the classroom. For this weather lesson, students use a psychrometer to measure the humidity in the classroom. Learners complete a lab packet.

Learners explain the importance of water in our daily lives. For 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.

Students 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...

Students 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. Students support their...

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.

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

First graders investigate composting. In this biology lesson plan, 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 lesson 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.

Fourth graders determine the impact of native forests, local clearcuts and local clearcuts and local reforestation projects on the survivablity of Rainbow Trout in their area. They record and document the stages of the trout throughout...
