Plants Grow from Air & Water
植物从空气和水中生长
Description
Support an argument that plants get the materials they need for growth chiefly from air and water, not from the soil
Mastery Evidence
- Explain that plants take in carbon dioxide from air and water from soil to make food (photosynthesis)
- Argue that most of a plant's mass comes from air (CO₂) and water, not soil minerals
- Describe a simple investigation showing soil mass barely changes while a plant grows significantly
Assessment Prompt
If your child knows plants need water and sunlight, can they also explain that most of a plant's 'building material' actually comes from air and water rather than dirt?
