K-PS2-2

SCUSD NGSS Curriculum Guide
 * K-PS2-2: Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.* ** [Clarification Statement: Examples of problems requiring a solution could include having a marble or other object move a certain distance, follow a particular path, and knock down other objects. Examples of solutions could include tools such as a ramp to increase the speed of the object and a structure that would cause an object such as a marble or ball to turn.] [//Assessment Boundary: Assessment does not include friction as a mechanism for change in speed.//]

Science Background for the Teacher:
"Analysis" at this grade level means assessing whether something happened or not (yes it did, no it didn't).

Key Vocabulary:

 * ramp || speed || prediction || turn ||
 * push || pull ||  ||   ||

Possible Assessments (formative and/or summative):
Have students explain orally and/or in drawings how to get a ball from one place to another and knock something down. Make a prediction before experimenting and then compare it to what actually occurred.

Key Student Activity:
The ramp portion of Balance and Motion of FOSS (currently in 2nd grade FOSS kit).

Students will experiment with ramps and blocks to get balls to move from one place to another, turn (by hitting something), and knock something down.

Key Teacher Demo/Activity:
Use sentence structures such as: I observe... I predict...  I notice...

Common Student Misconceptions:
[Descriptions of common student mistakes or misconceptions related to this topic.]

Things to Avoid/Correct:
Do not teach how friction effects speed at this grade level.
