Do you know how plants get the energy they need to grow and reproduce? They do not eat like humans and animals do; they make their own food with a process called photosynthesis.During photosynthesis, plants convert light, water, and carbon dioxide from the air into oxygen and sugars. In this activity, you will be able to observe the oxygen producti...
The leaf disk assay measures the rate of oxygen production in the leaf disks, which is a representation for the rate of photosynthesis. When you placed the leaf disks in your syringe, you probably noticed that they all floated on top of the solution. This is because leaves have air pockets within their structure to facilitate gas exchange between d...
Every living organism needs energy to grow and reproduce. Humans and animals eat foods with carbohydrates, proteins, and fats to produce the energy they need to survive. But plants do not eat. They make their own energy source in the form of energy-rich carbohydrates (sugars) through a process called photosynthesis. Photosynthesis is a multistep, e...
There are many factors that affect the rate of photosynthesis or how fast plants make oxygen. For example, you can change the temperature of the baking soda solution. Do your leaf disks start to fl...Test how the intensity of the light affects photosynthesis. Place the cup closer to your light source and farther away. How do your results change?Different plants have different amounts of chlorophyll, which are the pigments that absorb the sunlight during photosynthesis. How do different plants compare in your leaf disk assay?Plants need carbon dioxide for photosynthesis that you provide in the baking soda solution. Find out if changing the baking soda concentration has an effect on photosynthesis!Links

Nov 22, 2019 · The science of photosynthesis can be difficult for students, especially younger students, to understand without hands-on activities allowing them to see what they are being taught. Lab experiments that teach the fundamentals of photosynthesis can be conducted with children as young as elementary school.
Dec 9, 2022 · Easy photosynthesis experiment. Materials: Procedure: Place students in groups and pass out two cups of water, two fresh leaves, 2 small rocks, a hand lens, and a lab sheet. Students place a leaf in a clear cup of water. Then, they place the other leaf in the other cup of water. Put one of the cups in a sunny spot and one in a dark spot.

Grab a leaf and paint a thin layer of the clear fingernail polish on the underside of the plant leaf. Let it dry. Take a piece of packing tape and place it on top of the underside of the leaf.
1. In-person lab: Measure rate of photosynthesis in spinach leaves. Prepare a solution of water and sodium bicarbonate by dissolving 1 g of baking soda in 1 liter of water. Collect several spinach leaves and place them in a beaker of water for a few minutes to hydrate them. Fill several test tubes or small beakers with the sodium bicarbonate ...
