What your child will learn
Photosynthesis
- Plants Make Their Own FoodExplain that producers make food using energy from sunlight.
- Inputs and Outputs of PhotosynthesisIdentify carbon dioxide, water and light as inputs and sugar and oxygen as outputs of photosynthesis.
- Inside the ChloroplastExplain the role of chlorophyll in capturing light energy.
- Matter and Energy in PlantsTrace how matter and energy move into and through a plant.
- Photosynthesis Review ReviewReview how photosynthesis cycles matter and stores energy in food.
Using food for energy
- Food as FuelExplain that food contains stored chemical energy.
- Cellular RespirationDescribe how cells combine sugar and oxygen to release energy.
- Building the BodyExplain how molecules from food are rearranged to support growth.
- FermentationDescribe how some organisms release energy from food without oxygen.
- Using Food for Energy: Review ReviewReview how organisms break down food to release energy and build new molecules.
Senses and the brain
- Sensory ReceptorsExplain how sensory receptors detect information such as light, sound and touch.
- Nerves Carry MessagesDescribe how nerve cells send signals to the brain.
- The Brain RespondsExplain how the brain processes signals and sends a response.
- How Memories Are MadeExplain how the brain stores information as memories.
- Senses and the Brain: Review ReviewReview how senses and the nervous system gather and respond to information.
- Unit 2 Test: Energy and Matter in OrganismsShow what you learned in the whole unit (Photosynthesis, Using food for energy, Senses and the brain) by answering mixed questions.

From the lesson “Plants Make Their Own Food”
Which of these living things is a producer?
Show the answer
green algae in a pond. Green algae make their own sugar by photosynthesis, so they are producers. A mushroom may look plant-like, but it cannot make its own food; it absorbs food from the rotting log it grows on.
Hint kids see after a wrong try: “Look for the one that can make its own food from sunlight.”
