A. The Scientific World View
By the end of 2nd grade, students should know that:
- When a science investigation is done the way it was done before, we expect to get a very similar result.
- Science investigations generally work the same way in different places.
|
B. Scientific Inquiry
By the end of 2nd grade, students should know that:
- 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.
- Tools such as thermometers, magnifiers, rulers, or balances often give more information about things than can be obtained by just observing things without their help.
- Describing things as accurately as possible is important in science because it enables people to compare their observations with those of others.
- 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.
|
C. The Scientific Enterprise
By the end of 2nd grade, students should know that:
- Everybody can do science and invent things and ideas.
- In doing science, it is often helpful to work with a team and to share findings with others.
- A lot can be learned about plants and animals by observing them closely, but care must be taken to know the needs of living things and how to provide for them in the classroom.
