 | This web page contains problem sets in PDF format. The goal of these problems is to teach students about astronomy and space science by using mathematics and real-world problems. New problems will be posted each Tuesday by Noon (EST) during the school year! |
This Week's Problems:
Problem 152: The Hubble Law - Students plot the speed and distance to 7 galaxies and by deriving the slop of the linear model for the data points, obtain an estimate for the expansion rate of the universe known as Hubble's Constant. [Grade: 6-8 | Skills: Plotting data; determining the slope of the data;]
Problem 151: Time Zone Math - Students learn about time zones and perform simple clock calculations using common United States and European time zones. [Grade: 3-5 | Skills: time units; addition, subtraction]
Previous Problems:
Problem 150: Cosmic Bar Graphs - Students interpret simple bar graphs taken from astronomical data. [Grade: 3-5 | Skills: finding maxima and minima; fractions; extrapolating data]
Problem 149: Equations with One Variable - Students solve formulas of the form 2001 = 1858 + 11x to find 'X'. [Grade: 3-5 | Skills: addition, subtraction, multiplication, division; solving simple equations]
