A four-row table drives this 3-page 5th grade science sheet. It compares gravity on Earth, the Moon, Mars and Jupiter and gives the weight of a 100-pound object on each: 100, 17, 38 and 253 pounds. Part 1 asks where the object weighs least and most and how much less it weighs on Mars than on Earth. Part 2 has three written questions on whether mass changes, why Jupiter's pull is stronger and why an astronaut jumps higher on the Moon. Page 3 is the answer key.
“Compare the weight of the same object on different worlds using a table.”
Part 1 asks where a 100 lb object weighs least and most, and how much less it weighs on Mars.
“Explain that mass stays the same while weight changes with the strength of gravity.”
Part 2, question 4 asks whether mass changes, and question 6 links weaker gravity on the Moon to higher jumps.
A table with the world, its gravity compared with Earth and the weight of a 100 lb object, and three questions with answer boxes. Students pick the least and most, then subtract 38 from 100.
Three written questions, with a photo of an astronaut jumping on the Moon beside the last one.
The Moon (17 lb), Jupiter (253 lb), 62 lb less, and short model answers for the three written questions.
Use the fraction column
Ask students to estimate a 60 pound backpack on the Moon with the one-sixth column before looking at the weights.
Why 40 and 38
The Mars row says about four tenths and gives 38 lb. Ask students why 40 and 38 differ. Both are rounded figures, which is a good moment to talk about about.
Jump question
Show the photo on page 2, then have students finish the sentence The Moon pulls less, so before they write in full.
