Simple Science: Melting Snow

 
  

When it was snowing we did a ridiculously simple science experiment, asking the question: what happens to snow when you bring it indoors.  Science is all about good observational skills, questioning, recording, explaining and testing ideas, so we set about learning some of these.

First we started off by predicting what we thought might happen to the snow.  
Then we set about observing it regularly, (we should have really kept a timer to see how long it took.)  Each time we checked on it we described what we saw happening.
We tried to explain what was happening and why.  We looked up online about the structure of snowflakes and the structure of water (at a very basic level)
Finally we thought about what we could have done differently to make it a better test (e.g. putting a lid on the container, using a timer to record observations at set intervals, using a thermometer to record temperature, weighing the contents of the jug at the start and the end.)

So at a very basic level we covered the area that form the structure of  the academic scientific research journals of hypothesis, methodology, results, conclusions and discussion - all with just a measuring jug of snow.  And even us adults learnt something new - that as the snow melted it didn't just sink down, it formed a column in the middle of the jug first - now we've got to try and find out why this happened, just so you know even as adults we're always learning too!
