Stars Beneath Your Bed: The Surprising Story of Dust
1 The Nature of Science
For Grades: K-2
Learning Goal 1
People can often learn about things around them by just observing those things carefully, but sometimes they can learn more by doing something to the things and noting what happens.
Learning Goal 2
Tools such as thermometers, magnifiers, rulers, or balances often give more information about things than can be obtained by just observing things unaided.
Learning Goal 3
Describing things as accurately as possible is important in science because it enables people to compare their observations with those of others.
Learning Goal 4
When people give different descriptions of the same thing, it is usually a good idea to make some fresh observations instead of just arguing about who is right.
