5. 5. your name 4. The marble took up space in the water so it has volume. (4)
6. 6. your name 5. All the containers can store 500 cm³ of oxygen because oxygen is a gas and does not have a definite volume. It can fill smaller or bigger containers. (4)
7. 7. your name 6. The balloon becomes lighter when air is removed. This shows that air has mass. (1)
8. 8. your name 7. The systems in our body work together. (1)
9. 9. your name 8. The digestive juices break the food down into simple substances in the mouth, stomach and small intestine.
