Seventh graders research about the climate and weather in different biome types. For this biology lesson, 7th graders create a brochure of their chosen biome using Microsoft Publisher. They present their work in class.

Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Seventh graders study the environmental factors that affect population growth. In this biology lesson, 7th graders create a city following certain criteria. They present their posters in class.

Seventh graders explore how milk spoils over time. In this biology lesson plan, 7th graders discover how pH changes as microorganisms enter the food and multiply. They explain the benefits of pasteurization process.

Learners 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 create a postcard about endangered species. In this biology instructional activity, students identify how human activities endanger other species. They research and recommend ways to help protect them.

Students explain the importance of chlorophyll in plants. For this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.

Students identify the different leaf pigments and colors. In this biology lesson, students perform chromatography to separate them. They explain how light affects green leaf colors and causes falling leaves in autumn.

Students observe seeds growth and examine the different parts of the seedling. For this biology lesson, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

Students discuss the importance of plankton in the ocean ecosystem. In this biology lesson, students identify the different types plankton by observing them under the microscope. They explain how plankton population affect global climate.

Students identify different plant hormones and explain their function in plant development. For this biology lesson, students investigate how IAA affect root growth. They study the history of auxin discovery.

Students conduct various experiments to investigate plant transpiration. In this biology lesson, students explain how this process helps maintain the hydrologic cycle. They measure the rate of water loss in plants using a potometer.

Students explore amyloid proteins through a series of experiments. For this biology lesson, students explain the causes of Alzheimer's disease. They identify common symptoms related to this condition.

Students conduct a series of exploration activity on how vaccines and antibodies work. In this biology instructional activity, students test how antigens and antibodies work in the body. They discuss the benefits of vaccines in promoting...

Students conduct a variety of experiments to explore gel electrophoresis. In this biology lesson, explain how this process separate DNA and RNA. They discuss the practical applications of this method.

Students explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Students conduct a variety of experiments to explore protein. In this biology instructional activity, students solve a mystery by testing for the presence of glucose, protein starch and triglycerides. They explain how DNA transcription...

Students conduct an experiment to determine the temperature tolerance of yeasts. In this biology instructional activity, students collect data and compare them by plotting graphs. They explain how extreme temperatures affect organisms.

Sixth graders observe different microorganisms under the microscope. In this biology lesson, 6th graders draw and describe the samples they see. They study the root nodules of plants and explain how the plants benefit from those bacteria.

First graders build a terrarium in order to observe animal and plant life dynamics. In this biology instructional activity, 1st graders compare how organisms survive in different environments. They write their observations and analysis...

Sixth graders create a KWL chart about microorganisms. In this biology lesson, 6th graders create and label a diagram on a microbial mat. They investigate the processes involved in the carbon, oxygen and sulfur cycles.

Students investigate the factors affecting population growth. In this biology lesson, students collect data from the lab and graph them. They estimate population size using a mathematical formula.

Fifth graders identify the symptoms of asthma. In this biology lesson, 5th graders draw and label models of heart and lungs. They conduct a survey on asthma and construct graphs based on result.
