Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.

In this organism worksheet, students review the characteristics that determine if something is alive or not. This worksheet has 5 fill in the blank and 7 matching questions.

High schoolers conduct an experiment to observe the response of maize roots when rotated 90 degrees.

Students use the scientific inquiry method to identify the changes in a plant's life cycle. In groups, they plant different types of plants and use a chart to compare and contrast their growth rates. They share their conclusions with...

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...

Students investigate their environment by growing plants in class.  In this botany lesson plan, students discuss the lifespan of plants and animals and how they must be cared for continuously over time.  Students grow a plant...

Students examine the characteristics of a South American tropical rainforest. They analyze maps, develop graphs, listen to the book, The Great Kapok Tree, and create a rainforest mural.

Students examine the concept of extinction in relationship to the dinosaurs. In this elementary science lesson students become familiar with dinosaurs and that they are extinct. Students differentiate between different types of dinosaurs.

Students design an appropriate and usable storyboard and then create a claymation video. They take digital photographs frame by frame, then assemble the stop-motion movie using video software.

Students explore insects and closely related organisms. They examine the growth and development of a lady beetle. Students classify insects and organize them. They investigate pest management.

Throughout history, the growth of big cities has resulted in the destruction of ecosystems. In the case of Chicago, IL, a grassland that was once home to bison, deer, wolves, and foxes quickly became a booming city of over three million...

Students examine what factors influence climate.  In this investigative lesson students compare the factors that influence climate and how they effect tree growth.

In this plant response worksheet, students will explore the different responses plants have to different stimuli, including light and gravity. Students will complete 7 multiple choice questions and 3 fill in the blank questions.

Sixth graders examine renewable energy sources such as ethanol.  In this photosynthesis and biomes lesson students complete a project on farming techniques. 

Fourth graders explore the concept of photosynthesis. They investigate the effects of light on seedlings. Students grow plants and record the data. Students view satellite images that show the monthly amount of vegetation present in the...

Students understand what a habitat is. They determine why a habitat is important to our environment no matter where it is located. Students observe and recognize natural habitats in their surroundings.

Learners investigate seeds and their growth. For this agriculture lesson, students read the book How a Seed Grows and discuss the seed cycle. Learners examine real seeds and identify their properties. Students create a set of sequencing...

Learners examine how seeds germinate in a culture.  In this germination instructional activity students germinate seeds in gelatin and observe the growth of the plant.

Sixth graders observe school ground trees planted nearly 3 decades ago.  For this ecology lesson, 6th graders examine a group of trees planted near their campus and measure the diameter, circumference and growth of the tree compared...

Students investigate plant tropisms using the scientific method. In this life science instructional activity, students learn about tropisms and test the response of corn seedlings to gravity. Response questions, extensions, and an...

Students investigate relationships between plants and animals and how living things change during their lives. In this life cycle lesson, students split different types of seeds apart to see the beginning life stages of future plants.

First graders observe the effects of varying amounts of water, sun, and air on lima bean plants. They also predict and describe their outcomes in a written report.

Students attempt to determine the optimum growing conditions for barley. They assess the effects of a number of substances such as ammonium chloride and urea on the plants

Students discover how plants and animal ecosystems are affected by the growth of a city. In this ecology lesson, students study and observe a plant over a period of time. They develop a creative presentation of their data and share them...
