Photosynthesis and Transpiration

As a way to combine life and physical science, or simply as an investigation of plant transpiration, this instructional activity is sure to inspire! Middle schoolers capture the moisture given off by plants that are placed in different...

Plants need food to survive, just like any other living organism. Young biologists analyze an experiment performed in 1610 by Jan van Helmont to determine if plant nutrition is obtained through the soil. First, lab groups work together...

Students conduct an experiment to evaluate whether plants need light to survive and grow. They observe and gather data about plant responses to different growth regimes, analyze the data, and make conclusions about basic plant needs.

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...

One friend explains to another that plants combine water and carbon dioxide with the energy of the sun to produce sugar and oxygen. She mentions the roles of the roots, chloroplasts, and stomata in an engaging video that reviews how...

What do plants need? Students examine the effects of light and air on green plants, learning the processes of photosynthesis and transpiration. Student teams plant seeds, placing some in sunlight and others in darkness. They make...

Meet adorable, animated chloroplasts as they produce glucose with the help of the sun. Viewers learn how carbon, oxygen, hydrogen, and electrons are combined to form carbohydrates with an engaging video. The narrator also explains how...

Read about the four steps of photosynthesis in this brief, simplified tutorial.

Learners recognize the importance of plants as they perform an experiment involving photosynthesis. Students determine the optimum wavelength of light for photosynthesis by exposing plants to different colors of light, collecting data,...

Wouldn't it be great if you could produce your own food? Scholars learn about the processes of photosynthesis and cellular respiration in plants. They consider how to use photosynthesis as a model of an efficient system and how to apply...
