Heating substances 13-1-09
My prediction
Water will steam and bubble.
Sugar will melt into treacle.
Jelly will melt into liquid.
Margarine will slide into liquid.
Chocolate will move into brown liquid
We used
Jelly
Water
Sugar
Chocolate
Margarine
Apple pie base
Pegs
Candle
Matches
What we did
Mrs Durman lit the candles and gave us water which she put in our apple pie bases. Then we held it with a peg above the flame and watched. The same process repeated for the other substances.
What happened
The water steamed and bubbled.
The sugar melted into treacle and bubbled like a volcano.
The jelly bubbled and melted.
The margarine slid and melted
The chocolate steamed, bubbled and melted.
Conclusion
I think they liquefied because of the heat.
The next day when we looked at the substances they had solidified.
