About these photosynthesis worksheets

Plants make their own food. In photosynthesis, leaves use the energy in sunlight to turn carbon dioxide from the air and water from the soil into sugar, and they give off oxygen. Surprisingly, most of a plant's mass comes from the air, not the soil.

These photosynthesis worksheets include a labeled diagram, a blank diagram to label and a cut and paste twin. A reading passage tells the story of a famous willow tree experiment, a data page compares plant and soil mass, a sort shows what goes in and what comes out, and a sequencing page follows energy from the sun to a glass of milk.

Every page is black and white, prints on US Letter or A4, and every page with right answers has an answer key on page 2.

Standards

  • NGSS 5-LS1-1Support an argument that plants get the materials they need for growth chiefly from air and water.
  • NGSS 5-PS3-1Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
  • CCSS.ELA-LITERACY.RI.5.4Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 5 topic or subject area.

How to use them

  1. Start with the labeled diagram and the equation in words.
  2. Read the willow tree passage, then ask: if the soil barely changed, where did 164 pounds come from?
  3. Use the energy path page to connect photosynthesis to the food we eat.
  4. Finish with vocabulary and the quiz.

Teaching tips

  • A common mistake is to think plants eat soil. Soil gives small amounts of minerals; most of a plant's mass is built from carbon dioxide and water.
  • Animals use the energy in food to move, grow, repair their bodies and stay warm. That energy came from the sun.
  • Chlorophyll, the green material in leaves, captures the light.
  • The plant data page uses made-up practice numbers.

Questions teachers and parents ask

What is photosynthesis in simple words?

It is how plants make food. Leaves use sunlight to turn carbon dioxide and water into sugar, and they give off oxygen.

Where does a plant get its mass?

Mostly from carbon dioxide in the air and from water. In the 1600s, a willow tree gained about 164 pounds while its soil lost only about 2 ounces.

Is there a blank photosynthesis diagram?

Yes. There is a blank diagram with a word bank and a cut and paste version, both with answer keys.
