  2. 2. Balance Activity Solid, Liquid Or Gas?Game 1 Q2 Q1 (1) (2) Q3 (2) Solid, Liquid or Gas? Game 2 Q4 (4) Q5 (3) Solids, Liquids and Gases are matter. All matter have mass and occupy space. Liquids changes its shape according to the container. It also cannot be compressed. Air does not have a definite volume. No matter how much air is pumped in, it takes the volume of the ball which is 250 cm 3.
  3. 3. Q8 Q7 (1) (4) Q9 (4) Q10 (1) Q11 (2) Watch : Growth of A seedling The seed coat protects the seed. A fair test : one with mineral salts and the other without. The rest are the same. Seeds need water , warmth and food to germinate. Q6 (4) Video : Water takes up the space occupied by air Not all plants reproduce from seeds. Some plants reproduce from plant parts such as stems, leaves and even roots. Watch : Conditions for Seed Germination View : Table of Germinating times Of Seeds
