Key Stage 3 Science

QuestionAnswer
Draw a diagram showing how a particle in air may vibrate when a loud sound is passed through it compared to a quiet sound. How is volume linked to amplitude The greater the volume the greater the amplitude (size) of vibration. Scan
What materials ( medium) can sound travel through? What do sound waves carry Solids liquids and gases. Sound waves carry energy
Rank these in terms of how fast sound travels through them from fastest to slowest? Gas, liquid solid. Why are they in this order Solids liquids then gases. In solids the particles are closer together so the energy can be transferred quickly by collision
Explain how sound waves are detected by the ear, there are 6 stages. Use as many key terms as possible.
What is the human hearing range 20Hz to 20000Hz
Explain using the key terms reflected, absorbed and transmitted how different types materials affect if sound can travel from the ground floor in a building to the first floor
How do bats and dolphins use echo location to find their way around and their prey
Sound is a longitudinal wave, what does this mean? Draw a diagram showing how particles in a gas move when a sound wave passes through them Longitudinal waves are produced by vibrations of objects that move backwards and forwards. The particles that carry the sound only vibrate backwards and forwards
Surface water waves are transverse, what does this mean? Draw a water wave showing how the water molecules vibrate. Label the crests and troughs and the amplitude on the diagram. Transverse waves are produced by the vibrations of objects that are up and down. The particles in water are moving at right angles to the direction the wave is travelling at

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
