5 Free Photosynthesis Worksheets for Middle and High School

Learn and review with unique activities including a maze, scavenger hunt, and more.

For even more free science ideas and printables, head to our science hub! You’ll find resources in every science subject for middle and high school.

Teaching photosynthesis this year? You’re in the right place! Five fantastic photosynthesis worksheets are ready to help your students learn and review this essential topic. There are activities for both middle and high school classrooms along with a teacher’s guide and answer key. You can say “So long!” to searching for unique and engaging activities for your photosynthesis lessons.

Check out the photosynthesis worksheets included:

Diagram and reading passage with questions.

Introduce your students to an overview of photosynthesis with a diagram they will label. Then, use the provided reading passage to have students read, highlight, or annotate the section to become more familiar with the photosynthesis process. The corresponding questions will test their understanding. Plus, both the diagram and reading questions can serve as awesome review tools before test time!

We’re loving this unique and fun activity! Students will start in the top left and answer each question in the green boxes. Once they select the correct answer, they’ll shade in that pathway to lead them to the next question to work on.

Scavenger Hunt

Get students moving! Cut out the question cards and place them around the room. Students can start at any station and use their answer sheet to write out any work and their answer. Based on the answer they gave, they’ll find the next station to go to.

Cut and Paste

Ask students to cut out the answer cards and they’ll work to match them in the correct space within the chart. Once their answers are finalized, they can paste them in! You can even ask students to color-code or draw a diagram on the answer cards to help them remember.

High school biology teacher Lacey VanBuskirk helped us create these amazing photosynthesis worksheets.

AP Biology - Investigation: Photosynthesis

Background and prelab (view as google doc ).

Photosynthesis fuels ecosystems and replenishes the Earth's atmosphere with oxygen. Like all enzyme-driven reactions, the rate of photosynthesis can be measured by either the disappearance of substrate, or the accumulation of products. The equation for photosynthesis is:

6CO 2 + 6H 2 O ------light--------> C 6 H 12 O 6 + 6O 2 + H 2 0

To determine the rate of photosynthesis, you could measure the production of oxygen, which is released when photosynthesis occurs or the consumption of carbon dioxide.

Leaf Structure and Function

In this investigation, you will use a system that measures the accumulation of oxygen in the leaf. Consider the anatomy of the leaf. The leaf is composed of layers of cells. The spongy mesophyll layer is normally infused with gases, oxygen and carbon dioxide. Leaves (or disks cut from leaves) will normally float in water because of these gases. If you draw the gases out from the spaces, then the leaves will sink because they become more dense than water. If this leaf disk is placed in a solution with an alternate source of carbon dioxide in the form of bicarbonate ions, then photosynthesis can occur in a sunken leaf disk. As photosynthesis proceeds, oxygen accumulates in the air spaces of the spongy mesophyll. The leaf becomes buoyant and floats.

While this is going on, the leaf is also carrying out cellular respiration. This respiration will consume the oxygen that has accumulated and possibly cause the plant disks to sink. In other words, the buoyancy of the leaf disk is actually an indirect measurement of the NET rate of photosynthesis occurring in the leaf tissue.

Experimental Question: What factors affect the rate of photosynthesis?

Pre-lab Questions - these should be completed before the scheduled lab.

1. How can the rate of photosynthesis be measured?

2. Where in the cell of the leaf do you find air spaces?

What is the function of the stomata?

3. What will happen if you remove the air from these spaces?

How will air return to these spaces?

4. Instead of carbon dioxide, what will be used to as the reactant in this lab?

5. List any factors that you think may affect the rate of photosynthesis. Consider environmental factors that you could manipulate during the lab.

Baking soda | Liquid soap | Plastic syringes (10 mL or larger) | Leaves (spinach or ivy) | Hole punch or Straws | Cups or beakers | Timer | Light source

Analysis: To make comparisons between experiments, a standard point of reference is needed. Repeated testing of this procedure has shown that the point at which 50% of the disks are floating (ET50) is a reliable and repeatable point of reference.

Graph your data for the experiment. X-axis is Time (min) and Y-axis is # floating disks.

Be sure to include a key for each sample set. There should be four lines on your graph. Determine the ET50 for each set of leaf disks.

Conclusion:

What is the relationship between the variables aand photosynthesis rate? This is your CLAIM .

What evidence supports those claims (summarize data)?

Provide reasoning that linke the evidence and the claim and explains why this relationship exists. A discussion of photosynthesis is appropropriate in this section.

A newer version of this lab is available which includes an INQUIRY activity and allows students freedom to collect data on different variables: Investigation: Photosynthesis
