Scientific Comparison Worksheets Grade 7

1. Emma is comparing the populations of four cities, each written in scientific notation on a chart: City A: 2.5×10⁵, City B: 8.0×10⁴, City C: 1.5×10⁶, City D: 4.5×10⁵. Help Emma arrange the cities in order from smallest to largest population. Write your answer as a sequence of letters separated by commas (e.g., A, B, C, D).
2. Emma is comparing the populations of three cities written in scientific notation on a bar graph. The bar for City X reaches a height representing 6.5 × 10⁵ people. The bar for City Y reaches a height representing 3.2 × 10⁶ people. The bar for City Z reaches a height representing 8.9 × 10⁴ people. Order the cities from smallest population to largest population.
3. Order: 8.2×10⁷, 9.1×10⁶, 7.5×10⁸, 6.3×10⁷

2. Mason is studying a diagram of the solar system that shows the distances from the Sun to various planets. The distance from the Sun to Mercury is shown as 5.79 × 10⁷ km, and the distance from the Sun to Venus is shown as 1.08 × 10⁸ km. On the diagram, a third planet, Mars, is labeled with a distance of 2.28 × 10⁷ km from the Sun. Arrange the three planets (Mercury, Venus, and Mars) in order from the shortest distance to the longest distance from the Sun.
3. A shipping company transports two types of cargo. Container A carries 7.5 × 10^6 kilograms of goods, while Container B carries 1.25 × 10^5 kilograms of goods. How many times heavier is Container A than Container B?
