Seventh graders create a closed ecosystem and place it where is it visible to others in the school. They label it with posters describing the interdependence of living things in the ecosystem. They discuss what might happen to the...

In this science worksheet, students focus upon the concept of decomposition and collect data in order to make interpretations or observations.

Teen-agers discuss how fresh produce is brought into areas that do not have agreeable growing conditions and read an article from Canadian Agriculture at a Glance. They write an essay about projects that may help provide food in these...

Students compare the growth of watermelon from commercial seeds and those harvested from a watermelon. They complete science journals showing these comparisons based on the data they collect.

Learners study pictures of seeds and the conditions in which they grow during their study of archaeobotany. They infer ancient plant use by looking at archaeobotanical samples. They determine the change of plant use by interpreting a...

First graders explore the specific needs, characteristics, and uses of plants. They discuss the needs of plants as they grow. Students observe plants in various settings as they grow and note the changes they see.

Pupils identify and explain the parts of a flower and their role in the life cycle of flowering plants, including pollination, seed dispersal, and germination. Students recap the following information: that plants need light, warmth, and...

Learners examine how solar energy is absorbed and used.  In this solar energy lesson students complete several activities that allow them to better understand solar energy. 

Students experiment with milk to understand the importance of pasteurization. In this pasteurization activity, students learn background knowledge about bacteria in milk and the process of pasteurization. They complete an experiment to...

Students examine birdseed to see if it is a fertilized seed. In this birdseed garden lesson, students experiment with birdseed on a sponge to see what grows. Students record the growth of seeds.

Students role-play coyotes looking for natural resources.  In this natural resources lesson, students examine the relationship between animal life and the environment.  Students play a game that demonstrates how natural...

Students explore physical science by conducting a plant experiment. In this scientific method lesson, students discuss questions scientists ask in order to properly explore certain subjects. Students utilize two plants and place one in...

Students explore the various issues and problems faced by endangered species globally. They research the plight of endangered species, create a poster of a selected animal, and present their poster and research to the class.

Fourth graders explore tree rings. In this plant biology lesson plan, 4th graders construct a KWL chart on tree rings and examine real tree rings. Students identify the changes that happened during the tree's life and its actual age....

Students gather mosquito eggs to record the mosquito life cycle using drawings, descriptions, and any other appropriate means. In small groups, they analyze and describe the process of complete metamorphosis. They classify mosquitoes...

Fifth graders explore the cotton plant. In this cotton lesson, 5th graders research the process of growing cotton. Students explore the economic and cultural differences in the states that grew cotton for trade and industry.

Students recognize consist stems, trunks, leaves, and roots. They compare different types of roots by observing and comparing photographs. Aterwards, they observe the growth of a lima bean plant and document changes in root and shoot...

Fourth graders explore the four basic needs of plants. They examine plants as they grow. Students discuss the changes that they see in the growing plants. They observe what happens to a plant when one of its basic needs is taken away.

Students build an aquatic ecosystem using large glass pickle jars.  In this ecology lesson, students build and ecosystem then observe and collect data on the habitats.   In this long term project students observe a...

Students explore grazing animals in a dry forest. In this science lesson, students act out the role of a grazer in the dry forest. Students cut their growing lawn and observe what happens after being cut. Students explore differences...

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. 

Second graders read literature regarding the growth of seeds. They investigate how seeds need water and light to sprout and then grow. They experiment by planting their own bean seeds. They record the progress of their seeds in both...

Fifth graders observe and categorize different sections of a park and it's ecosystem. In this categorizing lesson plan, 5th graders collect different facets of nature from a nearby park (without disturbing the ecosystem). They map,...

Pupils investigate Daisyworld, a very simple planet that has only two species of life on its surface - white and black daisies, and bare ground. They construct a Stella model of Daisyworld and perform guided experiments to explore the...
