B.C. Science Probe Grade 5/Chapter 4:Design your own experiment

Step 1
Place your tile, sandpaper, fur and wood on a table,
Step 2
Take your tile and push it along the sandpaper, observe how much friction is made when you move the tile along the sandpaper,
Step 3
 Repeat step 2 except with the fur instead of the sandpaper, 
Step 4
Repeat with the wood,


Prediction
Was my prediction correct?
 I predict that I would need more force when I slide the tile across the sandpaper, 
Yes, my prediction was correct,
And I wouldn’t need as much force for the fur and wood,
Yes, my prediction was correct,
Interpret Data and Observations
1.Which surface required the greatest amount of force to move the block?
Answer: The sandpaper,
2. Which surface required the least amount of force to move the block?
Answer: The fur,
3. How did the surface texture effect the amount of force needed to move the block?
Answer: The surface of the sandpaper was rough and created more friction, making the block stop faster. However, the surface of both the fur and wood was smooth, creating less friction, which caused the block to move easily.
4. Look back at my prediction. Did my results fully support, partly support, or not support my prediction? 
Answer: My prediction was exactly correct, the result was the same.











B.C Science Probe Grade 5/Chapter One: Force/Chapter Two:Weight

Chapter 1

Check My Understanding of Force:
1.What is a force?
Answer:A force is a push or a pull on a object.
2. Think about riding a bike or skateboarding. Choose one of these activities and describe, in words or pictures, how force is used to...

  • start and stop moving
  • change speed
  • change direction
Answer:You use force to do such things by...

  • pushing or kicking or holding or getting in the way of the object you want to start or stop moving
  • pushing or kicking gentler or harder
  • pushing or kicking the object in a certain direction
Chapter 2

Check My Understanding of Weight:
1. What tool can you use to measure force?
Answer: A spring scale.
2. Would you expect to get the same results in the Try This activity if you did it on the Moon? Explain your answer.
Answer: No, the spring scale wouldn't have the same results because of the low gravity on the Moon.

Connections Canada First Project


Try this:

  1. Western Cordelia seems to be the highest part of Canada
  2. I live on the southeast part of BC, which is higher than Alberta.
  3. Nova Scotia seems to be at risk of flooding in the spring because of how low the land is.
