Milkweed Monitoring
Ninth graders study milkweed and see how it is effected by ozone. In this air pollution lesson students complete a lab activity that includes data analysis.
Curated OER
Starch
Learners examine the basics of starch and how it is used in food. In this photosynthesis lesson students experiment with variables that affect starch production in photosynthesis.

Carbon Dioxide - Sources and Sinks
Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
Curated OER
Stomata
Students explore what the stoma does for a plant. In this botany lesson students complete a stomatal peel experiment and measure its densities.
Curated OER
Sea Ice Research
Students study sea ice and its importance in climate and climate change. They discuss sea ice as a presence of a food source for marine animals in the arctic and complete a lab activity. After completing the lab, they watch a video...

Testing Leaves for Starch: the Technique
Like good scientists, kids often want to see first-hand why things are as they are; they can do just that in the starch-testing photosynthesis activity found here. Depending on the age of your pupils, you may wish to do the investigation...
Curated OER
Alcoholic Fermentation in Yeast
Biology learners investigate the effect of sucrose concentration on yeast alcoholic fermentation. During the lesson,they compare and contrast the processes of cellular respiration and alcoholic fermentation. They design an experiment to...
Curated OER
Chlorophyll
Students explain the importance of chlorophyll in plants. In this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.
Curated OER
Stomata: Microscopic Openings that Let Plants Breathe
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.

Glucose
High schoolers conduct various experiments on glucose. For this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
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.

Plant Transpiration
Young scholars conduct various experiments to investigate plant transpiration. For 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.
Curated OER
Color Change in Leaves
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.
Curated OER
Plankton / Phytoplankton
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.
