Learners determine the physical and chemical factors that affect plant growth. In this biology instructional activity, students explain the role of hormones in plants. They investigate how competition with other plants affect their growth.

Fifth graders use modern technologies which allow them to gain a new, dynamic, and intersting understanding of themselves, their community, and the world. They focus on environmental education and the effect of the environment on plant...

Students construct a defined plot on school grounds and observed patterns in plant life. They count trees, shrubs, cacti and record on a data sheet. They compare data and generate a plant diversity overlook for their school.

Eighth graders experiment to identify the nine factors needed for plants to grow healthy. They choose one of seven topics to research and develop an experiment based on scientific method, and complete oral and written reports based on...

Students conduct a series of experiments on mulching. In this earth science lesson, students discuss the benefits of mulching on soil. They explore how different types of mulch affect plant growth.

Students investigate the effects of soil temperature, water availability, photo period and other variables of the growth of purple loosestrife. They observe the growing conditions of plants and alter them by adding water, isolating the...

Students grow duckweed, observe what happens when an organism population is allowed to grow without predation or competition, view videos about invasive species, and develop a proposal for controlling the growth of an invasive species in...

Students explore how climatic factors influence the growth of plants. They create an experiment to find how variations in water, light, and temperature affect plant growth and describe how precipitation and geography can affect the...

Seventh graders examine how the environment can affect biological processes. They identify the best conditions for the germination of bean seeds. They record and analyze their data. They write about their observations in an essay.

Students investigate the pH of the soil in which different plants grow. They design and carry out an experiment to determine the factors that affect the growth of a population of plants, identifying and controlling major variables...

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...

Third graders study the factors necessary for plant growth and how plants adapt to their environment. They examine ow different plants require different environments to thrive.

Students examine climatic effects on ecosystems. They plant tomatoes and observe the differences in plant growth with differences in light. They create picture collages of plants, animals, and insects found in each climate of the U.S.

Eleventh graders are introduced to the effect of gravity on plant growth. They describe the major processes and mechanisms by which plants grow, develop, and supply various products, including energy and nutrition, needed by other...

Students investigate plants and the effects beetles have on the plants. In small groups, they collect plants and observe the beetles as they interact with the plants. They record the conditions including temperature, cloudiness, length...

Students research the effects of day-to-day weather on animal migrations, plant growth and other seasonal events. They consult maps, observe and record local conditions, keep journals and use their collected data check hypotheses.

Students discover how seed germination varies according to the soil type. In this soil science activity, students discuss what plants need in order to grow and investigate various types of soil. Students use their senses to describe each...
