Activity One: How much do you weigh?

Procedure:

Write your weight (or an estimate) here:

For a different plant, multiply your weight by the number given in the “New” Weight Chart. Example for the moon – for a person weighing 60 pounds on Earth: 60 x 1/6 = 10. A 60-pound person would weight 10 pounds on the Moon!

Follow the example and fill in the blanks in the “New” Weight Chart. Show your work.

“New” Weight Chart

Planet	Multiply your Earth weight by:	Your “new” weight
Mercury	0.4
Venus	0.9
Earth	1
Moon	0.17
Mars	0.4
Jupiter	2.5
Saturn	1.1
Uranus	0.8
Neptune	1.2
Pluto	0.01
Sun	28

Activity Two: How old are you?

Procedure:

Figure your age in Earth days. (Your age x 365)

For the terrestrial planets, divide your age in Earth days by the number of Earth days in a planet’s year. The answer is your “new” age. Example for Mercury – for a person 20 years old on Earth: 20 x 365 = 7300 Earth days old. 7300 / 88 (Earth days in Mercury’s year) = 83. The 20 Earth-year-old person would be 83 years old on Mercury!

For the outer planets, find the number of Earth days in each planet’s year. Then divide your age in days by the number of Earth days in that planet’s year. The answer is your “new” age. Example for Jupiter – for a person 20 years old on Earth: 20 x 365 = 7300 Earth days old. 12 Earth years x 365 Earth days/year = 4380 Earth days in one Jupiter year. 7300 / 4380 = 1.7. The 20 Earth-year-old person would be 1.7 years old on Jupiter!

Follow the examples and fill in the blanks in the “New” Age Chart.

“New” Age Chart

Terrestrial Planets	Approximate Length of Year	Your “New” Age
Mercury	88 Earth Days
Venus	225 Earth Days
Earth	365 Earth Days
Mars	687 Earth Days

Outer Planets	Approximate Length of Year	Your “New” Age
Jupiter	12 Earth Years
Saturn	29.5 Earth Years
Uranus	84 Earth Years
Neptune	165 Earth Years
Pluto	248 Earth Years

Activity Three: How far could you jump on other planets and the moon?

Procedure:

Determine how far you can jump on the Earth. To do this, pick a starting point and jump as far as you can off of both feet. Have your partner mark where you land and measure the distance. Record this in the table. Do this five times, and then find the average.

Take your average length jumped on Earth and divide it by the planet’s gravity to give you how far you would jump on that planet. Example for Saturn – for a person whose average jump is 5 meters on Earth: 5 / 1.32 = 3.79. A person who could jump 5 meters on Earth would only jump 3.79 meters on Saturn.

Follow the example and fill in the charts below.

Jump 1	Jump 2	Jump 3	Jump 4	Jump 5	Average

Location	Average Length on Earth	Gravity	Length
Moon	0.17
Mercury	0.38
Venus	0.86
Mars	0.38
Jupiter	2.87
Saturn	1.32
Uranus	0.93
Neptune	1.23
