High schoolers carry out an experiment to monitor diurnal fluctuations in dissolved oxygen, carbon dioxide, pH, and water temperature. They determine the CO2 and pH of the samples (and optionally, dissolved oxygen). Students complete...

Students investigate how weather affects how plants grow. They collect data on weather and plant growth for a week and display the data on a graph. For a culminating experience they design a movie using software that shows plant growth...

In this science test activity, fourth graders complete 41 multiple-choice questions covering a variety of fourth-grade science concepts.

Students discover seeds are a source of life. They also label the parts of a seed and examine the conditions which are needed for the seed to start growing. They follow the life cycle of seeds.

High schoolers 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...

Young scholars evaluate/distinguish scientific fact from fiction. They discuss similarities and differences in the life cycles of various birds. Student use the Internet as a research tool.

Students plant seeds and observe the life cycle of the organism. They experimentally research the effects of radiation on seed growth. Students determine the effects of environmental pollutants on harvested seed.

Not only is this lesson about story retell, main events, and making predictions, it's also about plants. Youngsters will read the tale, The Tiny Seed as they explore the plant life cycle and early literacy skills. The lesson is very...

Young farmers explore the world of farm animals. They are introduced to a variety of animals, what their role is, how many legs they have, and what sounds they make. Worksheets and websites embedded in the plan are used to carry it out....

Students explore plant life by creating their own gardens in class. In this food growing lesson, students discuss the types of gardening methods Native Americans used in order to keep healthy. Students plant corn seeds in their school...

Sixth graders explore the concept of biodiversity.  In this biodiversity lesson, 6th graders discover a variety of planets and animals that live in forests, and how a rotting log benefits that environment.  Students also locate...

Students examine a variety of environmental and industrial roles of bacteria. explore where bacteria can be found and distinguish bacteria from other organisms.

Learners examine the value of ecosystems. They read and analyze an article, evaluate ecosystem services, research the benefits of biomonitors, and design a public service announcement.

Students use a purchased kit to explore the characteristics and life cycles of several butterflies including the Monarch, Western Swallowtail, Red Admiral and Painted Lady. They create a plaster casting of each species for study and...

Students conduct an egg candling activity to show the life inside a fertile egg. Students discuss the needs the egg has of the hen, as well as similarities and differences between plants and animals. Students complete a life cycle wheel...

Students observe dried bees, carefully glue them to toothpicks, and use them for cross pollinating their Brassica plants. They also describe reasons why two similar investigations can produce different results. Finally, students...

Students are introduced to the growth process of a potato. As a class, they place a potato on a plate and observe how long it takes for the eyes to appear. In groups, they follow a recipe to make potato soup that is shared with the...

Students discover gardening by documenting plants grown on school grounds.  In this botany lesson, students utilize digital cameras to capture images of plants on photo hikes which are turned into a slide show.  Students plant...

Discuss the animals and plants in the rainforest food chain using this lesson. Learners talk about and do research on the top predators from the Costa Rican region and create a model of one of them in class. They also make a visual model...
