Hands on science is the way to go! Learners conduct a lab experiment to help them explain how plants make food through photosynthesis. They test for the presence of starch in leaves using iodine solution and identify the basic things...

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...

Three activities introduce upper elementary ecologists to photosynthesis and food webs. In the first, an experiment is set up to determine how plants respond to different types of light. In the second, they connect organism cards with...

Students, using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, observe and record the role of light in photosynthesis. They consider plant production of carbon dioxide and the use of live materials in biological...

Students observe the changes between elodea leaves placed in darkness and light.  In this life science lesson, students experiment to find evidence of photosynthesis in elodea leaves. Students use indicators to detect the presences...

Students examine how photosynthetic rates can change by using different qualities of light. They practice using spectrophotometer and the scientific method to detect the absorbance values in light treatments.

Pupils 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.

Students determine the amount of water loss due the transpiration.

Students work together to design and participate in experiments to determine the rate rotifers eat. After completing their experiments, they record and analyze their data and identify any challenges faced during the procedure. They...
