Metals And Water

Last week we did an experiment about metal and water. First we placed the metal in cold water, then we heated it over a Bunsen Burner. Our aim was to observe the reaction different metals had when they were put in water.

Calcium reacted the most out of all the metals. It bubbled, fizzed, changed colour and temperature.
Lead was one of the metals that didn't have a reaction to either hot or cold water. This would make it ideal for plumbing.

Why do you think the calcium reacted so strongly when it touched the water?

Boiling Water Experiment

P - My group and I worked well together, sharing out the jobs evenly and setting up efficiently.

M - We didn't have enough time to see if our hypothesis was correct, because the water took too long to heat up.

I - There were a lot of contributing factors so each experiment would have had different results. Variables that altered the time it took the water to heat up include: Distance from the beaker and the Bunsen Burner, amount of holes on the collar and amount of water in the beaker.
