Note from the author:
On Tuesday we will complete Investigation 1 and end class with a graded CER!

Today you will complete investigations 2 and 3.

Please make sure to take your time and answer the questions fully in your notebook so you are prepared for Tuesday's CER!

Although I am not there I expect EVERYONE to complete their work and for it to be done well!
The teacher in the room will let me know how you have done!

Investigation 2
Required

  • Open up this page in your notebook.
  • If this is NOT in your notebook please add it to your notebook
  • Add the title to your table of contents

What page is this evidence in your notebook?
Sentence starter: It is on page _____.

Today as you work you will measure the kinetic energy of moving carts by looking at how far it has moved.
What is the best unit to measure the kinetic energy of the carts today?

Required
1

Watch the condition A video TWICE and record the related data in your investigation 2 data table found in your notebook.
In this video, you just watched a collision of objects with their original mass and their original speed when they collide.
Why is it important to first look at collisions in their original state before increasing the mass and speed? (Write in one complete sentence) Remember it doesn't have to be perfect!

BEFORE WATCHING:
When we double only the mass of the cart, how much further will it push the box?
(This is a prediction! It's okay if it is wrong!)

Required
1

Watch the Conditions B video twice then record the related data in your Investigation 2 data table.

What was changed in this investigation by the scientist?

Required

Was your prediciton correct or incorrect? Explain what actually happened.

Watch the Conditions C video twice then record the related data in your Investigation 2 data table.
What was changed in this investigation by the scientist?

Was your prediction correct or incorrect? Explain what actually happened.

Required
1

About how many times further did the box get pushed when the mass was doubled?
(Try your best we will talk about this on Tuesday.)

Sentence Starter: The cart went ____________ times further.

About how many times further did the box get pushed when the speed was doubled?
Try your best we will talk about this on Tuesday

Sentence Starter: The cart went ____________ times further.

What does this tell us about how much more kinetic energy the cart had in each case?

Copy and use the sentence starters:
When the speed was doubled the cart had _____________________.
When the mass was double the cart had _______________________.

Required
1

  • Based on these patterns, make a new set of predictions:
  • If you tripled only the cart's mass, how many times further would it push the box?
  • If you tripled only the cart's speed, how many times further would it push the box?
Copy and use the sentence starters:
When the mass of the cart is tripled I think the cart will _____________________.
When the speed of the cart is tripled I think the cart will _____________________.

Investigation 3
Required

  • Open up to the next blank page in your notebook
  • Add the page below to the next blank page
  • Add the title to your table of contents

What page is this evidence in your notebook?
Sentence starter: It is on page _____.

MORE DATA would allow us to predict Kinetic Energy accurately.
  • The track in the video was only 1 meter. There is not enough space to see increasing Kinetic Energy. We need a different TOOL so let's use the simulation below.
Go to this website:
https://www.openscied.org/collision2-simulation/
First, you will run the simulator to find out how the kinetic energy of an object changes when an object's mass changes.

REMEMBER:
You will only change the mass
The speed should stay at 10
To make the simulation start click setup then go/pause
Make sure to record the distance the cart was pushed
