This Grade 5 science worksheet helps students master the photosynthesis equation in simple words: sun plus water plus carbon dioxide gives sugar plus oxygen. Students fix grammar, fill in equation parts, and explain why sunlight starts every food web. Clear hints guide young learners through producer vocabulary while building writing skills, NGSS 5-LS1 thinking, and confidence with how plants make food and release oxygen for ecosystems.

Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
In Grade 5 science, plants makes sugar using sunlight.
Rewrite: In Grade 5 science, plants make sugar using sunlight.
2. Fix the sentence:
Photosynthesis need sunlight, water, and carbon dioxide.
Rewrite: Photosynthesis needs sunlight, water, and carbon dioxide.
3. Fix the sentence:
The leaf release oxygen into the air during the day.
Rewrite: The leaf releases oxygen into the air during the day.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. In Grade 5 science, plants use energy from the sun to power photosynthesis.
2. During photosynthesis, plants take in carbon dioxide from the air.
3. Plants pull water up from the soil through their roots.
4. Photosynthesis releases oxygen gas that animals breathe.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. In Grade 5 science, why is the sun called the start of the photosynthesis equation?
The sun is the start because its light energy lets plants combine water and carbon dioxide into sugar; without sunlight, photosynthesis cannot happen.
2. Name the two products plants make during photosynthesis.
Plants make sugar (glucose), which stores food energy, and oxygen, which is released into the air for animals to breathe.
