Presentation Transcript

• Glue quiz to p. 38 RIGHT

• On p. 38 LEFT, draw a picture that represents your Mars module and your energy source.

Read article “How do you…in space” together.

• Update TOC – notebooks due Friday!

• Label p. 39 RIGHT

• Get stuff from modules (if needed)

Force and Motion Unit Cover Page

Students will jigsaw the following 6 key concepts (each group gets one) and make a mini-poster (colored paper).

1. Glue slip to sheet.

2. Circle vocabulary words from the slip and list their meaning in your own words.

3. Draw 1 picture explaining the key concept.

4. Create/design an activity that could be used for a station in the classroom which allows other students to learn this concept. List supplies needed and numbered understandable steps for completing the activity. Make sure you use the metric system if you have them measure!

5. Pick the best ones that show all the concepts and students will travel through the stations completing the activity and recording their observations.

* Key Concept 1: A force is a push or a pull that changes the motion of an object.

* Key Concept 2: Motion is a change in an object’s position, direction, or location.

* Key Concept 3: An object in its rest position stays in its resting position until an unbalanced force acts upon it.

* Key Concept 4: An object in motion will move in the same direction and at the same speed until an unbalanced force acts upon it.

* Key Concept 5: Speed is a measurement of the rate of change of position with respect to time.

* Key Concept 6: Average speed is calculated by dividing the distance an object traveled by the specified amount of time it took the object to travel the distance (s=d/t).

* Key Concept 7: A distance and time graph illustrates changes in motion. Time, measured in seconds, is graphed on the x-axis and distance, measured in meters, is graphed on the y-axis.

Your Group Will Create a Mini-Poster For Your Key Concept the motion of an object.

* Glue slip to sheet.

* List vocabulary words from the slip and their meaning.

* Draw 1 picture explaining the key concept

* Create an activity that could be used for a station in the classroom which allows students to learn this concept. List supplies needed and steps for completing the activity.

How to Read a Spring Scale the motion of an object.

Spring scales

Masses

Forces can be balanced or unbalanced the motion of an object.

Ex: You ran out of gas…

Balance the motion of an object.

BALANCED FORCES

• all forces acting on an object are equal (object is at rest or constant motion)

• Ex: tug of war (no one winning), object at rest

Inertia the motion of an object.

• When forces are balanced, it seems like there is no force

• An object at rest stays at rest (until an unbalanced force acts upon it).

• Called inertia (laziness) by Newton [Newton’s 1st Law of Motion]

Inertia the motion of an object.

• An object in motion will move in the same direction and at the same speed (until an unbalanced force acts upon it.)

• Called inertia (laziness) by Newton [Newton’s 1st Law of Motion]

Fun in Space

Inertia in both cases! the motion of an object.

Inertia depends on mass the motion of an object.

• Objects keep doing what they are doing.

• It is harder to change their motion if they have more mass.

Broom and Spheres

Even objects at rest or in constant motion (not accelerating) have forces acting on them but they are balanced!

If the book is not moving, which of the following accurately describes the forces acting on the book and table shown in the diagram above?

A The book exerts more force on the table than the table exerts on the book.

B The table exerts more force on the book than the book exerts on the table.

C The forces are balanced.

D The forces are unbalanced.

UNB describes the forces acting on the book and table shown in the diagram above?ALANCED FORCES

one or more forces acting on an object are stronger than others

• Unbalanced forces cause a change in motion (speed up, slow down, or change direction - acceleration [Newton’s 2nd Law])

• Ex: gravity, friction, tug of war (winning)

Ex: empty v. full shopping cart describes the forces acting on the book and table shown in the diagram above?

• Do you push each cart with the same force?

• Do the carts have the same motion?

• What do you think would happen in space? (pushing v. lifting)

Friction is an unbalanced force describes the forces acting on the book and table shown in the diagram above?

• Friction is the force that stops motion.

• Friction is caused by surface bumps.

• Friction “produces” heat (thermal energy)

Gravity is an unbalanced force describes the forces acting on the book and table shown in the diagram above?

• Gravity is the force that always pulls you down (or toward the Earth)

• It is also the reason why our solar system looks the way it does.

Engage 2 – Inertia in space… describes the forces acting on the book and table shown in the diagram above?

2. Use the compass to determine which direction (N, S, W, or E) that this part of the room is facing. [Hold the compass until the needle stops. Rotate the compass so that the red lines up with north. Then figure out which direction you are facing.]

3. This object is at rest. describes the forces acting on the book and table shown in the diagram above?What is keeping it there? (2 words)
