Observing Earthworm Locomotion

For Teachers 6th - 12th Standards
One acre of land can contain more than a million earthworms. Scholars collect earthworms to observe their movements. Once placed on paper, the sound of movement often fascinates pupils. When placed on glass, the earthworm is unable to...

Measuring Respiratory Quotient

For Teachers 10th - Higher Ed Standards
How do scientists prove tiny living things respire? Young scientists build a respirometer and measure respiration rates in living creatures. By comparing the measurements of both plants and animals, they understand the similarities.

Digestion of Protein: Microbes

For Teachers 9th - 12th
Milk the resource for all it's worth. Young biologists perform assay techniques to test the digestion of protein. They place bacterial samples, fungal samples, trypsin solution, and distilled water on a milk-agar plate to see the effects...

Measuring the Rate of Metabolism

For Teachers 9th - 12th
Plant respiration can be a difficult concept for young biologists to grasp; with a hands-on lab, learners can collect and graph data, then calculate the metabolism rate for the plants they studied. If you do not have a respirometer,...

Investigating the Effect of Concentration of Blackcurrant Squash on Osmosis in Chipped Potatoes

For Teachers 9th - 12th
Model and explore osmosis using squash and potatoes. Young scientists expose chunks of potatoes to different concentrations of a squash solution. They compare the weights of the chunks before and after exposure to the solution and use...

Investigating Transport Systems in a Flowering Plant

For Teachers 6th - 12th Standards
Some weddings have flowers in a unique, unnatural color to match the theme. Young scientists take part in this process to learn about the function of the xylem as they observe colored water moving through a flower. Then, they experiment...
