Know your Newton!
If Mr. Brady gets to fire a musket during a Civil War reenactment, he has to be careful of the recoil*.
Which of Newton's Laws best explains why this happens?
Name that Law!
* recoil happens when the gun moves backwards into your shoulder after being fired.
What is a "Newton's Third Law"? (For every action, there is an equal and opposite reaction)
When Bryce did the activity with the two carts on the ramp, he noticed that the released carts would hit each other and then would bounce back from each other exactly the same distance, each time. He did this many, many times.
Keep track of the CCC used, there can be no repeated CCC answers for other point values.
Accept any reasonable answers-see a teacher for a "check" if necessary.
Keep track of the CCC used, there can be no repeated CCC answers for other point values.
What is "Cause and Effect"? Cause=cars hitting eachother. Effect-Bouncing back at equal distances.
What is "Patterns"? Patterns because each time you observe this, the same cause and effect pattern is noticable.
What is "energy and matter"? The matter are the carts, which are made of matter. Energy is involved as they move and when they hit each other.
Systems-The carts and the track are interrelated parts that work together to perform a function (moving the carts in a specific way which causes them to crash)
Stability and change -the obvious answer here...
If Miss McMahon can run 10 miles in 5 minutes, what is her speed? (you may not use a calculator or scratch paper)
What is 2 miles per minute?
If the force on an object 27N and acceleration = 9.8 m/s2, what is the mass of the object? Round to nearest hundredth.
What is 2.76?
The speed between point A and B. You must round to the nearest hundredth.
0 m/s
A crash test dummy goes for a ride in a very fast car. Luckily, the dummy puts on a seat belt, and when the car crashes into a wall, the dummy only gets a mild case of whiplash. This is because the seat belt stops the dummy from continuing to move forward, after the car has suddenly stopped.
Name that Law!
What is "Newton's First Law"?
When Hailey observed the Cat's Cradle in action she noticed that when one ball was lifted and released, a ball on the other end would bounce up at the exact same height. She only observed this once.
Keep track of the CCC used, there can be no repeated CCC answers for other point values.
Accept any reasonable answers-see a teacher for a "check" if necessary.
Keep track of the CCC used, there can be no repeated CCC answers for other point values.
What is "cause and effect"? Cause -1st ball lifted and released, 2nd ball reacting by lifting on opposite side.
What is "patterns"?
What is "energy and matter"? The matter is the spheres, which are sent moving because of the energy in the lifted and released first sphere.
Systems- The Cat's Cradle is system because it has interrelated parts (spheres, strings, etc) That work together to create the effects we can observe when using the Cat's Cradle.
Stability and change -the obvious answer here...
Eli observed a wombat climbing the side of the RMS building. He estimated the height of the building to be 2 meters and the speed of the wombat to be 1 meter per hour. How long did it take the wombat to reach the roof? (you may not use a calculator or scratch paper)
(If you get this correct, it is worth 2x the points! If you get it wrong you lose 1x the points)
What is two hours? Slow wombat...
(If you get this correct, it is worth 2x the points! If you get it wrong you lose 1x the points)
John used 20 N of force to push a chair. Cindy then moved it in the opposite direction. How much force would she need? (hint: there is exactly one correct way to answer this question)
What is "anything greater than 20 N?" (This answer must be specific, an answer that gives a specific number (like 21) should not be accepted.)
The speed between point B and C. You must round to the nearest hundredth.
10 m/s
It is never a good idea to bring a glass of milk when driving in a car.
Name that Law!
What is Newton's First Law?
An object in motion (the milk) will continue n motion when the cars stops or starts suddenly, causing the milk to spill.
When Kaitlyn observed the astronauts eating tacos in space, she noticed that the tacos would float in mid air until someone touched them and sent them moving.
Choose the cross cutting concept that best applies. Explain.
Keep track of the CCC used, there can be no repeated CCC answers for other point values.
Accept any reasonable answers-see a teacher for a "check" if necessary.
Keep track of the CCC used, there can be no repeated CCC answers for other point values.
What is "Cause and Effect"? Cause=touching tacos. Effect= making them move.
What is "Patterns"? Patterns because each time you observe this, the same cause and effect pattern is noticable.
What is "energy and matter"? The matter is the taco, which is sent moving because of the nergy in the astronaut;'s touch.
Stability and change -the obvious answer here...
Connor signed up for the 500 km race at RMS's 2020 Field Day. He is pretty confident he can run it in 10 minutes. If he succeeds, what will his average speed be? (you may not use a calculator or scratch paper)
What is 50 km per minute? (Connor is a monster-purely Olympic material)
I drove at 60 mph for 4 1/2 hours. How far did I drive?
270 miles

(If you get this correct, it is worth 2x the points! If you get it wrong you lose 1x the points)
The speed of the bus between points B and C. You must round to the nearest hundredth.
3.33 m/s

If the force applied to two spheres is the same, but one of the two spheres has more mass, then the less massive sphere will accelerate more quickly.
Name that Law!
What is Newton's Second Law? (F=ma)

If Ryan pushes a cart with 45 N of force and Paul starts to help him using 30 N of force, what is the net force?
75 N
Albert's average speed. You must round to the nearest hundredth.

A Bowling ball rolling down a ramp has greater inertia than a ping pong ball rolling down a ramp. (Be careful w this question!)
Name that Law!
What is "Newton's Second Law". (The bowling ball has greater inertia because it has greater mass. Because both spheres are rolling down a ramp, they are accelerating due to gravity. Their acceleration is equal. F=ma means that the sphere with more mass will have a greater force on contact and will therefore be harder to stop.)
