Snow Investigation

Our trip was cancelled because if the snow. We started a snow investigation instead.

We decided to investigate this. We made same size snowballs and we will check the bowls to see how much water is in the bottom.

The more water, the faster it melts! We set lots of timers so we can keep checking.

This is the result from the first check but there might be water in the other bowls too that is trapped in the materials. This is us doing our first check.

We then looked at magnified snowflakes and we looked at snow under our own digital microscope.

Nothing much happened on our next checks.

At 11.30am we moved the snowballs inside. At 12pm we had another look. The fabric and paper were getting wet and the snowball without anything looked mushy. The one in foil looks best. Isaac thinks the foil traps the cold air. We changed our class predictions.

This is what happened next.

In the end the fabric kept the snow coldest for longer.
