| Course: Physical Science | Grade Level (s): 8th |
| Content: Unit 4: Forces, Friction, Gravity, Momentum & Motion | Week: 17 |
| California Academic
Content Standards emphasized: 2. Unbalanced forces cause changes in velocity. As a basis for understanding this concept, students know: a. a force has both direction and magnitude. b. when an object is subject to two or more forces at once, the effect is the cumulative effect of all the forces. c. when the forces on an object are balanced, the motion of the object does not change. d. how to identify separately two or more forces acting on a single static object, including gravity, elastic forces due to tension or compression in matter, and friction. e. when the forces on an object are unbalanced the object will change its motion (that is, it will speed up, slow down, or change direction). f. the greater the mass of an object the more force is needed to achieve the same change in motion. g. the role of gravity in forming and maintaining planets, stars and the solar system. |
| Key Ideas: inertia, force, balanced force, unbalanced forces, net force, friction, resistance, gravity, Law of Universal Gravitation, action & reaction, weight, momentum |

[1]Grade/Collect/Pass out new PS SkW [2] Finish up "Is it a MATTER of the SIZE or the PUSH?" exploration into the nature of Newtonian motion, part II. [3] If Time remains, start "How do rockets go anywhere if the "rubber never meets the road?" exploration into the nature of Newtonian motion, part III. |
MEETING 2 |
[1] Hand in Ps POW, "Bobo and the Bean Machine" [2] Science Festival Project: investigation and data collection. [3] "Is it a MATTER of the SIZE or the PUSH?" exploration into the nature of Newtonian motion, part II. [4] If Time remains, start "How do rockets go anywhere if the "rubber never meets the road?" exploration into the nature of Newtonian motion, part III. |
HOME SESSION AGENDA/ ACTIVITY |
|
SESSION 1 |
[1] Make sure PS SkW is finished and your POW is started. |
SESSION 2 |
[1] Work on SkW. [2] Make sure you have finished the Text reading page 34-64* by the end of week 17 (this week). [3] POW due during the next class meeting. |
SESSION 3 |
[1] Work on SkW. [2] Text reading page [3] Make a draft copy of any data table that you will need to use for data that will be collected during the Investigation phase of you Science Festival Project. This table is due by the first class meeting of week 18. |
