a) Activity to show that sound can travel through solids:
Materials needed: Two tin cans, a string, a small object that can make a sound (e.g., a bell or a small musical instrument)

Procedure:
1. Tie one end of the string securely to the handle of one tin can.
2. Stretch the string taut and tie the other end to the handle of the second tin can.
3. Make sure the string is tightly stretched between the two cans.
4. Choose a quiet location for the activity.
5. One person holds one tin can to their ear, while the other person holds the second tin can against their mouth.
6. The person holding the tin can against their mouth gently taps the small object to create a sound.
7. The person holding the tin can to their ear should be able to hear the sound transmitted through the string.

Explanation: In this activity, the sound waves produced by tapping the small object travel through the string, which acts as a solid medium. The sound vibrations are transmitted from one tin can to the other through the string, allowing the person to hear the sound in the tin can held against their ear.

b) Activity to show that sound can travel through liquids:
Materials needed: A glass, a spoon, water

Procedure:
1. Fill the glass with water.
2. Place the glass on a table or any stable surface.
3. Take the spoon and gently tap it against the side of the glass.
4. Observe and listen to the sound produced.

Explanation: When the spoon taps against the glass, it creates sound waves that travel through the water. The sound waves cause the water molecules to vibrate, transmitting the sound through the liquid medium. The vibrations are then picked up by our ears, allowing us to hear the sound.
