Listen, chant and guess
Welcome to Force Station, little observers! Let’s warm up with a chant. Ready?
Listen, chant and guess
Listen, chant and guess
What is the chant about?
force
movement
speed
T:What is the chant about?
S:It is about force, movement and speed.
Look, think and say
T: Look at our experiment tools. We need force to pull the box.
T: Now think carefully: What did you learn about forces and movement?
Look, think and say
A force can make things move.
T: Look at our experiment tools. We need force to pull the box.
T: Now think carefully: What did you learn about forces and movement?
Watch and say
Watch and say
The same person pulls three boxes with the same force.
What's faster than Box C?
What is the fastest of the three boxes?
fast(原级,快的)
fastest(最高级,最快的)
faster(比较级,更快的)
T:The same person pulls three boxes. What's faster than Box C?
S: Box B is faster than Box C.
T: What is the fastest of the three boxes?
S: Box A is the fastest of the three.
Watch and say
The same person pulls three boxes with the same force.
What's faster than Box C?
What is the fastest of the three boxes?
Box B is faster than Box C.
Box A is the fastest of the three.

Look, guess and say
I think... is faster than...
... is the fastest.
Box A
Box B
Box C
T: Look at the pictures. Guess and say.
S: I think... is faster than...
S: ... is the fastest.
Look and say
What's faster than...?
What is the fastest?
... is faster than...
... is the fastest...
Discuss and share
Which one is the fastest?
S1: Which one is the fastest?
S2: ... is the fastest, because it's light and the force is big.
S: We think same force, light things move fast; same weight, big force makes it move fast.
Do and say
This box is light. It moves faster.
This box is heavy. It moves slower.
T: Now it's your turn to do experiments.
Push the boxes and talk about their speed.
Try to use 'faster' and 'fastest'.
S: This box is light. It moves faster.
S: That heavy box moves slower. It is the slowest.
Show and report
T: Let's make a group report.Talk about your findings about force and speed. Please speak clearly and loudly.
S1: We find big force makes things fast.
S2: Light things move faster than heavy ones.
Think and share
T: Look at these pictures. They are in our life. Which one moves faster? Share with us.
