We've been looking closely at measurement and why we need to use a standard unit of measurement to be able to compare our measurements with others.
Yesterday when we used our hands we discovered that we couldn't compare the measurements because they were all so different even though we were very careful with the way we measured and we were all measuring the same thing. We added our hand measurements to the Google form (on the left). It then graphed the answers for us.
Look at how different the measurements were ...
Today we created our own rulers and re-measured the items we measured with our hands yesterday using rulers we had created. We used strings of cm wide squares, we created a ruler that was 50cm long because it had 50 squares on it.
Here are some photos of our rulers in construction and of us measuring the same things we did yesterday...
Watch this space for our next analysis of our measurements.
Great investigation Room 18. The difference is your hand measurements is very noticeable. I am glad that we have standard units of measure otherwise imagine how topsy turvy our world might be if everything was built using peoples hand measurements.
ReplyDeleteVery interesting activities Room 18! It's a great way to show statistics data by using graphs!
ReplyDeleteGood morning Room 18. Standard measurements are so important and make it easy for us all to understand how big things are. What standard units of measurement have you discovered yet?
