Curated OER
Photosynthesis Explored
Students observe the production of gas as an effect of photosynthesis. In this biology lesson, students perform an experiment with pondweed and make measurements and predictions about photosynthesis and the plant.

Mutualism and Co-evolution A study of Flowering Plants and their Pollinators: Biology, Plants
These lessons use a variety of methods and approaches to teach flowering plant biology which includes seed germination; plant growth and food production through photosynthesis; plant transpiration and respiration; sexual reproduction...
Curated OER
Letting Off Steam
Learners examine the concept of transpiration. They work together to complete an experiment in which they see water loss in plants. They record their observations and discuss their conclusions.
Curated OER
Photosynthesis in a Jar
Students simulate Joseph Priestley's experiments using a bell jar. They demonstrate that oxygen is necessary for fire and animals but that given time, plants can create oxygen, allowing fires to burn and animals to breathe.
Curated OER
What Plants Need in Order to Survive and Grow: Air
Young scholars conduct an experiment to determine whether plants need air in order to survive and grow. They discuss natural resources, analyze slides, and observe and record data from the experiment.
Curated OER
Photosynthesis
Sixth graders are introduced to the process of photosynthesis by discussion and then by participating in an experiment. They then answer questions as independent practice project.
Curated OER
Sugar and carbohydrates, protein, fat and water - that's what little plants are made of!
Students identify photosynthesis as the mechanism by which plants convert sunlight energy into a usable energy source for plant processes. They identify photosynthesis as the mechanism by which plants create a molecule that can be used...
Curated OER
Monitoring Oxygen Level
Students measure oxygen percentages in room air and air exhaled after they perform various activities. They explore various websites, and record and analyze the data from the experiments.
Curated OER
Glucose Factory
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.
Curated OER
Water Quality and Dissolved Oxygen
Students investigate the relationship between dissolved oxygen and organic materials and aquatic organisms. This is a 3-lesson series in which students explore dissolved oxygen and then design an experiment testing the effects of changes.
Curated OER
The Water Cycle: Transpiration
Students identify and describe the stages in the water cycle. Using plants, they determine if they play a role in the cycle and measure the water the plants give off. They complete an experiment to determine if deciduous or coniferous...
Curated OER
Oxygen Factory
Fourth graders examine the interdependence of the oxygen and carbon dioxide cycle in an ecosystem through a laboratory investigation. After a lecture/demo, 4th graders complete the lab in groups.
