Use informational text to describe that food molecules, including carbohydrates, proteins, and fats, are broken down and rearranged through chemical reactions forming new molecules that support cell growth and/or release of energy.
The Massachusetts Science and Technology/Engineering Curriculum Framework (2016) outcome 8.MS-LS1-7 (Life Sciences) for Grade 8 says: “Use informational text to describe that food molecules, including carbohydrates, proteins, and fats, are broken down and rearranged through chemical reactions forming new molecules that support cell growth and/or release of energy.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Massachusetts Science and Technology/Engineering Curriculum Framework (2016).
How Plants Make Food: Photosynthesis and Respiration Grades 6–8
Where does a tree's mass come from, what happens to the sugar a plant makes, and how does the Sun's energy run a whole ecosystem? Three no-materials lessons with a 400-year-old willow experiment, printed atom cards and a carbon-atom role-play.
- What happens to the food a plant makes? 50–60 min
Teams rearrange 36 printed atom cards from carbon dioxide and water into glucose and oxygen, then back again, and prove that no atom is made or lost. At four case stations they read data on plants in the dark, sprouting seeds, weight loss and apple stores, and explain that plants and animals both respire.
