Curated OER
Evidence of Photosynthesis
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...
Science Matters
Photosynthesis-Cellular Respiration Cycle
The balance of nature can be a wondrous thing! With the 19th lesson of the 21-part series on systems, learners explore the cycle of photosynthesis and cellular respiration using a lab-based activity. Groups set up different test tubes...
Curated OER
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
Everybody Needs a Little Sunshine
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...
Curated OER
Mussel Your Way Through Photosynthesis
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...
Curated OER
Elodea Lab
Young scholars observe the changes between elodea leaves placed in darkness and light. For this life science lesson, students experiment to find evidence of photosynthesis in elodea leaves. Young scholars use indicators to detect the...
Nuffield Foundation
Measuring the Rate of Metabolism
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,...
Curated OER
Using Spectrophotometers to Examine Photosynthetic Rates
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.
Curated OER
Field Trip to test Water Quality
Students examine water quality indicators,test water quality and record their results. In this water quality instructional activity students complete a water testing lab and complete a lab report.
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.
Curated OER
Life In Extreme Environments
Learners 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...
Climate Literacy
Clean: Carbon Dioxide Sources and Sinks
In this lab activity, students use a chemical indicator (bromothymol blue) to detect the presence of carbon dioxide in animal and plant respiration and in the burning of fossil fuels and its absence in the products of plant...
