2. What is an object doing if it is in motion?
Moving
Explore: You can use TE Quick ACTIVITY. Divide the class into groups of four or five children. Have each group decide on a motion they can perform for the class. Tell two groups that they have to stay in the same place as they demonstrate their motion. Tell the other groups that their motion has to involve a change of place. Have each group perform its motion. Ask the viewers to describe the motion.
Another activity: Place a small object on top of the desk. ( block, gram cube, coin, pencil, toy car etc.)
Move the object forward by pushing it with your fingertip. Is your object in the same place?
Was there motion when you pushed the object? How do you know? (it changed position)
Now pull the object back with your fingertip.
Evaluate: What does it take to make an object move? (a force)
In your journal, define motion. Write and draw some examples.
What are some types of motion? Fast, slow, forward, backwards, circular, vibrating, jumping, etc.

3. What is motion? Things are moving. Things in motion change position.
Explore and Explain: Play the video clip What is Motion? If not available, have students demonstrate moving in different ways. Have students write essential ? And ask what is motion? Allow wait time and have students answer. (Things are moving. ) Then have a volunteer move from their desk to the front of the room and ask if volunteer in the same place or a new place. Say Things in motion change position. Have students give examples,
Have students define motion in their notebooks. Things are moving.
Things in motion change position.
Write and draw some examples.

4. Different Ways an Object can Move
fast
slow
around and around
straight
zig zag
up and down
slide
Explore and explain: Ask What are different ways that an object can move? Click and play video link: Different Ways an Object can Move. Add to first list.

5. What can you do to make an object move?
Give it a push or a pull
Explore:
Visit school playground. See Push and Pull at Play handout. Use the suggestions to explore.
Explain/Evaluate: Have students draw pictures and write about their Push and Pull at Play experiences.
Students can do Grade 2 Lab Zone Directed Inquiry: Make an Object Move
What did you do to move the object in the activity we just did?

6. What are a push or a pull that makes something moved called?
Forces
What are a push or a pull that makes something moved called? Click on and play link a push or a pull . Have students define What are forces? ( a push or a pull) in their notebook and draw examples.
Click on second link Forces
For more explanation. (

7. Pushes and Pulls http://www. bbc. co
Explore: Ask What happens when we push or pull an object? Predict.. What will happen when we change the force of the push or pull? Click on the link, Pushes and Pulls. Discuss what happened after activity.

8. Forces and Movement
Click on hyperlink: Forces and Movement in the slide title for more exploration and explanation .

9. Connecting Learning What happens when we push or pull an object?
What happens when I push or pull an object strongly?
What happens when I push or pull an object gently?
What is a force?
What are you wondering now about forces?
Review: Students can sing the animated song from SF, Use Some Force. If tape is not available, You can log into
Log in. Click on the Grade 2 Take it to the Net. Select Games, Unit C Physical Science. See animated song under Chapter 8. You can also do Chapter 10 Active Art: Measuring Motion.
Evaluation: Connecting Learning questions and from Discovery: Force and Motion

10. Puffer Paths Key Question:
How many puff does it take to move your sheep
from the pasture to the sheep pen? (See game board.)
Materials per student to make a cotton ball “sheep” :
drinking straw, cotton ball, chenille stick (pipe cleaner)
Materials per group: game board and tally sheet
Game Objective:
Count and record the number of puffs it takes to
blow a cotton ball “sheep” along a path on the game
board.
Compare your group’s data to the data for the whole
class.
Extend/Elaborate/ Evaluate Investigation:
See and follow the directions for the Gr. 2 AIMS Puffer Paths Activity T.G. and student pages on pp
