What this quiz should check

Topic: Photosynthesis and the cycling of matter and flow of energy (MS-LS1-6). A good grade 7 quiz on this asks students to:

• Name the inputs (carbon dioxide, water, light energy) and outputs (sugar, oxygen) of photosynthesis
• Explain that plants build sugar from carbon dioxide and water, which is where most of their added mass comes from
• Trace energy from the sun into sugar and then into animals that eat plants
• Explain that atoms are rearranged, not created or destroyed, as matter cycles

Misconceptions worth a question

• Believing plants get their food or most of their mass from the soil
• Thinking plants do not use the sugar they make or do not respire
• Mixing up matter and energy, such as saying energy turns into sugar molecules

Teacher tip: This standard's assessment boundary leaves out the biochemical steps of photosynthesis, so ask the AI for items about tracing matter and energy (diagrams, claim and evidence) instead of chemical pathways.

Always check the AI's answer key before you give the quiz to students.
