- What do 3 pigs, a wolf and a dragon have to do with the secret?
2. Need a clever idea
- What does Wolf want to do?
- Why can’t he do it?
- Do you have an idea that may help?
3. at the house of bricks
- Not nice!
- Why won’t the pig help?
4. at the house of sticks
- Would you let wolf in?
- Would you try to help?
5. at the house of straw
- Another no!
- What would you do if you were wolf?
6. huff and puff
- What’s the pig going to do now?
7. the note
- What do you think of wolf’s note?
- What should the pigs do?
8. an idea!
- What is the pigs’ idea?
- Will it work?
- Do you have a different idea?
9. at the creek
- The rocks feel lighter in water?
- Why?
- AHA? What new idea do the pigs have?
10. Success!
- It worked! They lifted the stone!
- What difference did the water make?
- What might be the secret on the tablet?
11. TIME to rest
- They seem happy.
- And tired.
- Are they becoming friends?
12. the house of straw is fixed
- That was nice of wolf!
- What should the pigs do now?
13. BE KIND
- What do you think of the secret on the tablet?
- If you could share a secret of life, what might it be?
14. the end
- The pigs look a bit apprehensive.
- What might happen next?
- How would you continue this story?
15. an experiment
Materials you need:
- a spring scale that measures 500 grams
- various masses (100-500 grams)
- a bowl of water
Try this:
- hang a 500 gram mass on the spring scale
- what is the reading on the scale?
- move the scale so the mass is submerged in the bowl of water (but not touching the bottom of the bowl)
- what is the reading on the scale?
16. eureka!
Read about Archimedes and his “eureka” experience at https://en.wikipedia.org/wiki/Eureka_(word)
17. will it sink or will it float?
Imagine this:
- you are standing in front of a pond
- you pick up a tiny pebble and you throw it in the water
- will it sink or will it float?
Now imagine this:
- you pick up a heavy log and you throw it in the water
- will it sink or will it float?
18. in a song
LIGHTER IN WATER
A song of Grade 1/2 student comments after exploring the weights of masses in and out of water.
19. relative density, coding + art
Let’s use the coding app at: https://researchideas.ca/density/
Below the canvas, there is a list of 2 objects: Object 1 and Object 2.
OBJECT 1
In the list of objects:
- click to select Object 1
- in the code window, you can see the code attached to this object
- notice that the object’s density is 1.1
- the canvas density is 1.0, so this object is more dense, which means it will sink
- under the code window, click on Run This Code to set the object in motion
Change the density of Object 1:
- click to select Object 1
- change the density to 1.5
- click on Run This Code
- what is the difference?
- try a density of 5
- notice the difference?
OBJECT 2
Refresh your browser window to reset the app.
In the list of objects:
- click to select Object 2
- in the code window, you can see the code attached to this object
- notice that the object’s density is 10.9
- the canvas density is 1.0, so this object is less dense, which means it will float
- under the code window, click on Run This Code to set the object in motion
Change the density of Object 2:
- click to select Object 1
- change the density to 0.5
- click on Run This Code
- what is the difference?
OBJECTS 1 AND 2
Refresh your browser window, to reset the app.
Let’s see the 2 objects interact:
- under the code window, click on Run All Code to set both objects in motion
- what happens when they collide?
- which object, and what part of its code, determines what happens when they collide?
Change the collision effect:
- click to select Object 1
- change the density to 0.5
- click on Run This Code
- what is the difference?
