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

In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay.
- 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.
- Virtual lab: Pigment Extraction. In Labster’s simulation, Pigment Extraction: Use photosynthesis to produce biofuel and reduce pollution, Roxy, the leader of a team of engineers, will take students on a journey over the sea and show them the most problematic facilities are the coal power plant and the fish farm.
- In-person lab: Chromatography experiment. This experiment provides a hands-on opportunity for students to develop important scientific skills, such as making observations, collecting and analyzing data, and drawing conclusions based on evidence.
- Virtual lab: Algae Pigment Analysis. In Labster’s online lab, Photosynthesis: Algae pigment analysis, students will help Roxy, the lead engineer in an environmental project, determine if dark-colored algae can do photosynthesis using green light.
Nov 22, 2019 · Lab experiments that teach the fundamentals of photosynthesis can be conducted with children as young as elementary school. These experiments are designed to supplement the more theoretical elements of photosynthesis since they illustrate the effects of sunlight deprivation on plants, rather than explicitly showing how plants convert sunlight ...
Apr 3, 2024 · 1. Diagram To Illustrate The Process of Photosynthesis. This visual representation includes the elements involved during photosynthesis, like carbon dioxide, hydrogen, oxygen, water, chloroplasts, carbohydrates, and sunlight. Learn More: Dreams Time. 2. Photosynthesis Relay Game.
Photosynthesis is the process where plants use water (H2O), carbon dioxide (CO2), and energy from sunlight to create sustenance in the form of glucose (C₆H₁₂O₆) and release oxygen (O2)into the atmosphere. A few activities, experiments, and projects help demonstrate how photosynthesis works, making it easy for young children to understand.
