Curated OER
Photosynthesis
Students conduct a variety of experiments on photosynthesis. In this biology lesson, students identify the factors required for the process to occur. They perform computerized experiments to test the amount of oxygen produced when plants...
Curated OER
The Effect of Temperature on Cricket Chirping
Students examine the effect of temperature on how often crickets chirp. In groups, they complete the experiment and answer lab discussion questions. They create a graph of temperatures and the amount of chirps and discuss the results.
Curated OER
Enzyme Lab
Students examine the effects of specific enzymes on samples of liver tissue, muscle tissue (chicken), apples, and potatoes.
Curated OER
Teaching about the Effect of Photosynthesis and
Students demonstrate the effects of photosynthesis and respiration. They decide which variables to analyze in a microcosm study. They produce a written paper, oral presentation, poster, or multi-media presentation
Curated OER
Glucose
Students conduct various experiments on glucose. In this biology lesson plan, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
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.
Curated OER
The Basics of Biochemistry
Science teachers can introduce basic chemical concepts to biology students.
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
Photosynthesis
In this photosynthesis worksheet, students follow the steps to complete a science investigation and then respond to 8 short answer questions regarding the photosynthesis investigation.
