5 WORKSHEET 1 Biomass: Energy Source Fact File! To help you get thinking about energy, we've got some great pages all about it! A - Agree C - Confusing I - Interesting D - Disagree Here s the need-to-know stuff about the energy source, biomass! Description All living things and organic matter are known as biomass. The energy released from biomass when it is eaten, burnt or converted into fuels is called biomass energy. This includes wood, wood waste, straw, manure, sugar cane, and many other by-products. Where can you find biomass? Biomass can be found all around us. How is it made into electricity? Biomass can be burned to heat water and produce steam. This steam propels the blades of a turbine. This is attached to a generator, which produces electricity. More to click... Curious facts about insulation Curious facts about solar power Curious facts about electricity What are the advantages of using biomass? It is a renewable source of energy, which means that it will not run out as long as it is replaced, for example by growing more crops or trees. Although carbon dioxide is released when biomass is burned, the plants absorbed carbon dioxide when they were growing. So the only additional carbon dioxide that is emitted is from farm machinery used in the process. It can use waste materials to produce electricity. It supports farmers because they can sell their crops for biomass fuel.

6 What are the disadvantages of using biomass? Burning biomass does produce some carbon dioxide gas overall, which contributes towards global warming, but in general it can be thought of as almost carbon-neutral. Biomass production can encourage intensive farming and may contribute towards deforestation if new trees are not planted. Growing and collecting the biomass can sometimes cause problems. It can be heavy and may need to be transported long distances. If food crops are used for fuel this can make them more expensive to buy as food.

23 ASSESSMENT /PROJECT Students have discovered through the activities in this unit that food scraps, dead plants, sawdust, and other matter usually thought of as garbage, are called biomass, which is a rich source of energy that can be used to produce electricity, heat, or fuel. In this project, students will compare the amounts of biogas produced by different types of biomass using the language of a science domain. ACTIVITIES STRATEGIES/ APPROACHES STEP 1 You have learned that food scraps, dead plants, sawdust, and other decaying organic matter, called biomass are a rich source of energy. You can get energy out of biomass by burning it, turning it into a liquid, or by turning it into a gas called biogas. You've probably burned biomass (like dead wood) before if you've ever built a campfire, and you've seen biogas being produced if you've ever watched cows happily munching on green grass. The cows eat a type of biomass (grass or hay) and turn it into the biogas, methane, in their digestive tracts. In this science fair project, you'll discover the energy contained in different types of biomass. Action Oriented Task HOTS: Applying Creating STEP 2 a. Students carry out an Action-Oriented Task** by conducting an experiment on biomass energy in groups. b. 12 different experiments would be carried out by 12 groups concerning different types of biomass. HOTS: Applying Creating c. Refer to the experiment tasksheets (SCREENSHOT1). _resources/elementary/biomass_activities.pdf d. Students discuss and plan how to conduct the experiments assigned to them. e. Each member of the group should be actively involved in carrying out the experiment.

24 Step 3: a. Science Fair Project - Students exhibit their experiments and present their findings. 21 st Century Learning: Gallery Walk b. Representatives from each group explain the results obtained in a Gallery Walk** activity.
