Students 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.

How do different minerals affect the growth of plants? Budding botanists find out in a multi-week experiment that has them using solutions with specific mineral deficiencies. While there is a lot of preparation for the investigation,...

First graders compare plant samples obtained from two different sites to explore how climate affects plants.

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...

Have your young scientists questioned why plants grow a particular way? Through this learning opportunity, scientists gain firsthand knowledge about how plants develop and various factors that affect rates of growth as they bring plants...

Note the way that plants change during the season by adopting a plant on your school campus. After your class chooses their plant, they research the plant's needs, how it differs from other plants, find ways to support their plant's...

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 investigate different factors that affect plant growth. They research the effects of water supply, radiant energy, air temperature, and soil temperature. Students also gather facts that influence plant nutrition that include the...

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

Pupils 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...

Young scholars keep a garden journal after planting a garden and discuss environmental stresses put upon the garden for growth. In this garden lesson plan, students plant the plants differently from one another and observe the outcomes.

Students study plant needs and growth by completing a gardening activity. In this plant study instructional activity, students watch a video and discuss plant growth needs. Students plant seeds in containers and water the plants....

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...

Young scholars 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.

What does it mean to be a good steward? Middle school environmentalists learn to care for their state's waterways through research, a guest speaker, and poster activity. Groups must locate and learn more about a river basin and the human...

Students study the process of plant reproduction and the biotic and abiotic factors that affect flowering phenology. In this plant reproduction lesson, students describe the interaction of environmental factors as it relates to...

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

Middle schoolers investigate plant tropisms using the scientific method. In this life science lesson, 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.

In this growing tomatoes worksheet, students plant tomato seeds in February, and follow their growth through the summer break. They observe and investigate the plant growth from seed to plant.
