Balloon Car - Race Day
The following video is Race Day for the balloon cars that both of my grade 10 Academic classes created. Included with each of the videos is the URL of their blog that they were asked to create to document the progress of design a balloon powered car. Those that do not have a URL, unfortunately, did not keep their blogs updated. Feel free to use their ideas to help make your own balloon car go FASTER or FURTHER. Good luck. Mr.P

Significant Digits
Key Concepts:
Be careful with zeros. Zeros in between non-zero numbers are significant. Zeros after the decimal are significant ONLY IF they FOLLOW any OTHER number.
Examples:
a.) 4000000 - has 1 significant digit (the zeros are there as place values showing size of the number)
b.) 95.00 - has 4 significant digits (we DON'T need those zeros because without them the value remains the same, HOWEVER, by us including those zeros we MAKE THEM SIGNIFICANT)
c.) 0.00003 - has 1 significant digit (zeros in front of the three are only there as place values. Without them the value of the number changes)
