Give your biology students a focused look at oxygen and carbon dioxide with ninety questions built for real classroom use, whether you are starting a new unit or reviewing before a test.
The set includes questions like "What is the formula for photosynthesis?", "Why is photosynthesis vital for life on Earth?", and "What is the relationship between photosynthesis and the carbon cycle?"
Because the three worksheets share the same content in three different formats, you can spread them across the week: one for diagnosis, one for practice, and one for assessment, without repeating a single question.
This set is part of a standards aligned biology unit. The unit also covers Introduction to Photosynthesis, Matter Cycling in Photosynthesis, Energy from the Sun, Food as Matter and Energy, Chemical Reactions in Digestion, and Energy Release in Organisms, all in the same three worksheet format, so your classroom routine stays familiar while the topic changes.
Suitable for Grade 7 biology classes, and for review at any point in the school year. This set is aligned to NGSS standard MS-LS1-6.
