Nutrition
Animal food comes from plants and other animals. Some animals feed their young.
Activity 3.2 (Make a bird feeder)
You will need: a plastic container - string - a hole punch fat - bird seed
Punch two holes near the top of the plastic container. Melt the fat (get an adult to help you). When the fat has cooled a little, stir bird seed into it. Carefully pour the mixture into the plastic container (do not fill it to the top). When the mixture is cold, thread the string through the holes and hang your bird feeder somewhere outside.
