Define the following vocabulary words to build more background knowledge for your challenge:
- density
- orbit
- velocity
- mass
Your challenge:
A scientist recently went to space and has asked for your help in organizing the obtained data. Distances and measurements in space often result in more specific numbers that are significantly longer because they haven't been rounded to ensure accuracy. Your job:
A scientist recently went to space and has asked for your help in organizing the obtained data. Distances and measurements in space often result in more specific numbers that are significantly longer because they haven't been rounded to ensure accuracy. Your job:
- Help make the measurements easier to understand by rounding as well as ordering the planets from least dense to most dense.
- Round the density measurements to the nearest whole number.
- Take a look at the average orbital velocity of the planets and order them from least to greatest.
- Round the average mass compared to Earth to the nearest tenth on a number line.
Extend Your Thinking: Visit the NASA website to obtain the orbital eccentricity of each planet and round each measurement to the nearest hundredth.
