Energy and ATP
Take charge of your biology class by using this exciting analogy to relate the ATP process with batteries. Pupils use batteries and rubber bands to simulate the phosphate bonds between molecules in the body. They measure the distance in...
Curated OER
Glucose
Students conduct various experiments on glucose. In this biology instructional activity, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.
Curated OER
Yeast
Students study the characteristics of yeasts. In this biology lesson, students conduct experiments to measure yeast respiration. They discuss the favorable conditions needed for growing them.

Energy Extravaganza
Tenth graders study how cells and organisms acquire and release energy through photosynthesis and cellular respiration. They explain that living organisms use matter and energy to synthesize a variety of organic molecules and they will...

Investigating an Enzyme-controlled Reaction: Catalase and Hydrogen Peroxide Concentration
Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Dissecting Lungs
Here is a lab activity where teens experience the respiratory system first-hand as they dissect lungs and identify key structures within the system. Although the website is written in British English with some slightly different verbiage...
Curated OER
Cell Energy-Colorful Respiration
Students examine the acid-base indicator, bromthymol blue (BTB), and what happens to it when you blow air into it or add plants and snails. Through an experiment, they test three different setups of BTB and record the color changes that...
Cornell University
Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

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.

Effects of ATP and Ions on Rabbit Psoas Muscle
Students prepare single strands of muscle cell. They microscopically examine muscle cells and identify bands of darker and lighter proteins. They predict, observe, describe and quantify the effects of ions and ATP.
Curated OER
Energy, Matter, and Organization
Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...
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
Sizing Up the Supersize Croc
Students examine and compare traits of humans and crocodiles. For this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile.
Curated OER
Eutrophication Experiments
Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.
Curated OER
Human Body Systems
Seventh graders investigate the structure and function of body systems and their inter-relationships. They draw and label the major body systems, observe demonstrations of various body systems, define key vocabulary terms, and compare...

Time Lapse Seed Germination with the QX3 Intel Digital Microscope
Students use the time-lapse feature of the QX3 Intel Digital Microscope
to observe germination of seeds. They use the QX3 Intel Digital microscope to create time lapse video films of seed germination experiments.
