BASIC SCIENCE JS1
1a. Classify Objects According to Their State of Matter:
- Solid: Table, chair, cup, glass, plastic, tyre.
- Liquid: Diesel oil, petrol, methane gas.
- Gas: Oxygen.
1b. Differences Between Plants and Animals:
- a) Cell Structure: Plants have cell walls, while animals do not.
- b) Mode of Nutrition: Plants are autotrophic, producing their own food through photosynthesis, while animals are heterotrophic, relying on external sources for nutrition.
- c) Locomotion: Most plants are fixed, whereas animals exhibit various forms of locomotion.
- d) Reproduction: Plants often reproduce through seeds, while animals can reproduce through various methods like giving birth or laying eggs.
2a. Differences Between Metals and Non-Metals:
- a) Conductivity: Metals are good conductors of heat and electricity; non-metals are poor conductors.
- b) State at Room Temperature: Most metals are solid; non-metals can be solid, liquid, or gas.
- c) Malleability and Ductility: Metals are malleable and ductile, while non-metals are generally brittle.
- d) Lustre: Metals are generally shiny, while non-metals lack a metallic shine.
2b. Uses of Metals and Nonmetals:
- Metals:
- a) Iron is used in construction for buildings and bridges.
- b) Copper is used in electrical wiring.
- c) Aluminium is used in making aircraft and packaging materials.
- Nonmetals:
- a) Hydrogen is used as a fuel for rockets.
- b) Oxygen is essential for respiration.
- c) Carbon is used in making pencils and as a fuel in the form of coal.
3. Classification of Energy Sources:
- Natural Sources: Sun, wind, uranium element.
- Artificial Sources: Petrol, battery, food.
4. Energy Transfer Explanation:
- (a) Striking a matchstick: Chemical energy in the matchstick is converted to thermal energy due to friction, resulting in the match igniting.
- (b) Pressing clothes with a pressing iron: Electrical energy from the iron is converted to thermal energy, which presses the clothes.
- (c) Pressing an electric doorbell: Electrical energy is converted to sound energy when the doorbell is pressed.
- (d) Kicking a ball: Kinetic energy from the kicker’s leg is transferred to the ball, causing it to move.
