The minute the words science experiment are mentioned in our house, the boys are normally as keen as mustard to get involved. Today's experiment, From Solid to Liquid to Gas, definitely got them going.
The objective of the experiment was to observe how water can change quickly from solid to liquid to gas.
By the way, the inspiration for this experiment, From Solid to Liquid to Gas, came from a book by Chris Oxlade entitled "Super Science. Matter and Materials Experiments". This is a great book full of easy experiments for budding scientists to try out.
- a tray full of ice cubes
- a pot
- a stove
- a thermometer (we used a temperature gun)
- a pencil (to record observations and temperature readings)
- a record sheet (you're welcome to download one from here).
We started by tipping the ice into a cold pot and measuring the temperature of the ice. At this stage, I noticed a few ice-cubes were disappearing (eaten by the scientists!!!).
Once we'd filled in our observation sheets, we placed the pot on the stove and turned on the element.
Over the next few minutes, we observed how the ice changed in both its appearance and form.
Once all the ice was melted, we took more temperature readings.
As the water continued to heat, we watched and observed any changes we could see happening.
The final temperature readings were taken after the water started boiling.
By that time, one of the scientists was reaching for the carton of eggs and getting ready for an impromptu morning tea! My question is ... do all scientists have this urge to eat their experiments? :o
We managed to get a bit more maths into this activity but working out how long it took to complete the whole experiment. Turns out it was relatively quick - 13 minutes to be precise!
Do you have any favourite science experiments involving water as a solid (ice), liquid (water) and gas (steam)? We'd love to hear about it. Please feel free to leave a comment on this post or on our facebook page.
