Lab 4 Explore the Solar System
Objective:
1.
Learn the relative sizes and order of the planets 2.
Making a scale model of the planet size. 3.
Review Kepler’s Laws. Equipment:
Internet Various sized balls How to do the Lab:
1.
Download the lab in the study module on eCampus to your computer
.
Answer all questions and fill data in the table. 2.
On eCampus, the same location, click on lab 4, then Browse for Local files, then click on the button Attach File to attach your file to submit. Background:
Our solar system is made up of the Sun, eight planets, about 56 moons, and numerous asteroids and comets. Most of the mass of the solar system is concentrated in the Sun, which is a medium-sized star. (Jupiter, the largest planet, has a mass just 1/100 that of the Sun.) However, most of the volume of the solar system is just empty space. The planets orbit the Sun at distances that are thousands of times larger than their planetary diameters. It is thus difficult to make models that show both distances between and sizes of the planets together. Part I. The size of Planets
Conversion:
1.609km = 1mile; 2.54cm=1 inch
Scale
: one earth diameter = 1 inch Example
: Mars diameter in the scale model: So Mar’s relative size to Earth is 0.53. If we use a model that let Earth be 1 inch, then, Mars size is 0.53inch, or 0.53x2.54 =1.35 cm.
Table 1 Size of Planets (14pts) Using the above scale model, each group (person) please represent your model with an actual object you see around you. You can find any creative way to represent the size of your planet, the possible choices are: basketball, golf ball, tennis ball, apple…... (5pts) What did you choose to represent Earth _______ What did you choose to represent Jupiter_______ Sun is ________________ times the diameter of Earth Venus is ___________ times the diameter of Earth Jupiter is____________ times the diameter of Earth Explore further: go to Planet-Sizes to compare earth’s size to all other planets.
