Photosynthesis: How do plants make food?

3rd - 4th

Students study why plants are green and how water is transported in them. They examine how plants respond to different amounts of light.

Plant Science: Introduction to Photosynthesis

Students explore the process of photosynthesis in plants. They discuss the purpose of photosynthesis and its components. Students discuss the importance of photosynthesis for plants and they examine the parts of the plant that play an important role in photosynthesis.

soil, Water, and Plants

Students examine the relationship between water retention and plant growth by conducting two experiments. They first compare the water retention qualities of clay, sand and loam soil types. Then they use the data from the first experiment to design the second plant growth and soil type experiment.

Science Activity 1: Light & Sound

Are you looking for lab sheets to go with your class experiment on plant response to light? You are no longer in the dark! This is a lesson that was written for a unit on light, but could easily be used to demonstrate plant behaviors in a life science class as well. Make sure to use quick-to-germinate seeds such as radish if you want the lesson to fit within the five-day period.

Rooting Into the Soil: Examining the Relationship Between Plants, Soil, And Water

Learners, in groups, conduct an experiment to compare how water moves through different soils. They discuss how different soils could have an impact on different plants.

Plants Alive!  How Plants Grow and Move

Students explore how plants move in response to the environment. In this plant lesson, students engage in three different experiments to investigate how plants grow and move. Resources available in English and French.

Living Life as a Plant

Students explore plant adaptations to their surroundings. In this plant adaptations lesson, students watch an interactive video of plant adaptations as well as videos about a desert biome and carnivorous plants. Students complete a plant adaptation experiment using corn seeds. Students complete a worksheet about 'Living Life as a Plant.'

What If There's No Light?

students discuss the importance of light and the consequences of living without it. Using a plant as a demonstration, students predict and observe what happens to a plant when it does not receive enough light. In groups, they experiment to discover the impact of a floating plant on dissolved oxygen. After collecting and organizing information, students report their conclusions to the class.

Why Are Plants Green?

Students smash plant parts and wait for visibility of chlorophyl to show why plants turn green. In this green plants lesson plan, students use acetone and filter paper for this experiment.

Why Plants Are Green

Learners discover the properties of chlorophyll in plants. In this plant biology lesson, students conduct an experiment to find where the chlorophyll in the plant is located. Learners are split into small groups and study plant parts. Additionally, students study what happens to each plant part when sprayed with acetone. In their small groups, learners infer what part of the plant contains the chlorophyll based on the reaction with the acetone. Students fill out a result chart.

All About Plants

Students identify plant needs. For this biology lesson, students watch All About Plants and then write a paragraph describing the various details about plants.
