Practical Investigation: Grade 5

Investigate How Long a Candle Will Burn:

Materials Needed:
- Three 10 cm long candles in sturdy candle holders
- One large glass bottle
- One smaller glass bottle (make sure that both bottles can easily fit over the candles)
- A box of matches
- A clock or watch

Procedure:
1. Light each candle using the matches.
2. Cover one candle with the large glass bottle and another with the smaller glass bottle. Leave the third candle uncovered.
3. Use the clock or watch to measure the time each candle burns until it goes out.
4. Record your observations.

In this investigation, you will observe the effect of the size of the glass bottle on the burning time of the candles.
