Study Notes
Energy around us
- Different types of energy exist including; food, heat, light, movement, sound
- Energy cannot always be seen but can be observed through its effects
- Energy can change things, not just move them
- Living things get energy through consuming food
- The harder an object is kicked, the further it will move
Energy transfers
- Energy can be transferred multiple times
- Energy transfer between things is called an energy chain.
- Energy transfers differently into different types of materials
- The sun's energy is transferred to a corn plant
- The corn plant is then consumed by a cow
- The cow then provides energy to a human
- The human releases energy through movement
- Ice can receive heat energy from a hand
- This transfers energy from the hand to the ice
Energy changes
- Hand energy is transferred to a drum to make sound vibrations
- Vibration energy from the drum then turns into sound energy
- Electrical energy can be changed into:
- Light energy
- Heat energy
- Movement energy
- Energy cannot be destroyed or created
- Energy is always around us
Energy and living things
- A producer makes its own food
- An herbivore is an animal that eats plants
- A carnivore is an animal that eats meat
- An omnivore is an animal that eats both plants and meat
- A consumer eats other organisms for energy
- The predator in a food chain is a consumer
- A food chain shows direction of energy transfer
- Food chains contain at least one producer and one consumer
- Example food chains:
- Carrot (producer) -> rabbit (consumer) -> fox (predator)
- Grass (producer) -> cow (consumer) -> man (predator)
