Middle schoolers show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity...

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 examine the effect of different types of light on the Earth. They discover the role of evaporation and the effects of the sun on the magnetosphere. They also observe different solar phenomena.

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.

Third graders view a clip of the video Backyard Safari, "Trees," and portray the life cycle of a tree. They also view a clip on structures of a tree and draw a diagram of a tree in their science journals.

Learners 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...

Sixth graders explore the concept of biodiversity.  For 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...

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...

Students investigate how plants absorb carbon dioxide during photosynthesis. In this biology lesson, students differentiate photosynthesis and cellular respiration. They discuss the important role of plants in the environment.

Students identify the nutrients found in potatoes and the process of growing a potato plant. They role-play the potato life cycle, view a flannel board story, plant grass seeds in potatoes, and play hot potato.

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...

Second graders construct a pond habitat in the classroom using a small swimming pool partially filled with water, real cattails, a tree log adjoining, and plastic animal life appropriate to a pond setting. They examine the frog in detail...

Students examine a still-life painting. They discuss the observation of nature by scientists and artists and explore the symbolism of biological life cycles depicted in a painting.

Students recognize that plants and soils have a close relationship. They view a photo essay on the common practice and natural process of composting. Afterwards, they observe the process of plant decay over the course of several days.

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Pupils work together to observe plants and flowers through their life cycle. In groups, they make predictions and record changes in a journal. Using this information, they create their own original artwork and discuss the plants life cycle.

In this biology lesson, high schoolers identify the different types and parts of the plant. They complete a crossword puzzle with 37 questions about plants.

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

Students identify the stages of apple growth. In this agricultural activity, students read the story I Am Apple and sing the song "Round the Apple Tree." Students place pictures of the stages of an apple into the correct order. Students...

Fourth graders explore the human and animal connection along with the idea that death is a part of the life cycle. They read "Where the Red Fern Grows." Students examine the feelings and emotions surrounding death and they discover the...

Students investigate the food known as the tortilla. They research the growth cycle of the corn plant and how tortillas are made from it. The importance of the tortilla according to the Hispanic culture is explained to the students. The...

Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.
