I learned that the more mass = more faster. And the results of the whole class was that the big marble took the shortest time. In my mind, I thought that the little ball would end up to have the shortest time. What the ball is bing pulled down is by Gravity.

This can apply to a pinball machine by, you can’t have a ruler in a pinball machine, so we were thinking that you can have a ramp like skateboarders go on, than it would go on a little curve.

Thanksgiving

I’m thankful for my family, my sibling, and everything you have done for us to make us healthy. We had chapel today and it was fun. We had “testimonys” from two ladies. One from Mr. Meyer’s wife, and Mrs. Genzink. We sang songs like Forever Reign, Blessed Asurance, and You Are My All in All. I’m thankful for teachers that work at Zeeland Christian, and for the bible, that we can read and learn from your word, and learned more about you. We are thankful for the food you have given us, the shelter you have given us so that we can live in. And the air you have given us so that we can breathe. And we saw two videos about Birds. And we heard from the tow ladies abotu their struggles. And they told us what they are thankful for. Mrs. Genzink told us that she had lost a son named Travis, befre he could go to school , walk, or crawl. And her daughter has diabtetes and she has to take medicine and shots. When Mrs. Genzink eats food, it feels like you hit you funny bone. But it feels numb on your toes, or fingers.

Pinball Wizard – Newton’s Laws Of Motion

Newton’s Laws Of Motion

Law #1: Law of Inertia

  • An object in motion will stay in motion. And an object at rest will stay at rest.  Until the object ricochets of of something.

    • We did a demonstration where someone was in a car and he hit the ruler and was in a fake car accident. This is an example of the first law because the body continued in motion.

    • We hit a tennis ball on top of a roll of cardboard, and we tried to make the ball into the bucket. It may be worked. The tennis ball stayed at rest

    • When the troll hit the ruler, the motion was the troll moving forward. And the car wanted to stay at rest once it hit the ruler.

Law #2: F = m x a

  • Something that is heavier than an other object, will weigh more, and go more slower. For example, a medicine ball and a basketball. A medicine ball is heavier than the basketball. So the basketball will roll faster and longer than a medicine ball.

    • We pushed the medicine ball and the basketball, and most of the time the basketball went farther than the medicine ball.

    • We pushed each other on chairs, and we had to see who was more heavier than the other person.

    • We pushed Mr. Commeret on a skateboard, and he had more fore = more accleration

Law #3: Action – Reaction

  • For every action there is an equal and opposite reaction

    • In Mr. Bouman’s class, he tied a balloon to a straw. (He use tape to tied it around the straw) The action is the air coming out of the balloon, and the reaction is when the balloon is moving forward.

    • A funny part, was when the balloon was out of air, the tape was all over the balloon when the balloon lost all of the air

    • If I threw a tennis ball against a wall, the action is me throwing the ball and the reaction is the ball coming back to me after it hits the ball

  • On a rifle, you can get a action-reaction. Once you pull the trigger, and the bullet shots out, you get a little “kick”, (really a reaction).

This can apply to pinball machine by the launcher. Once you pull back the launcher, the reaction is the ball that is being hit by the launcher, and the action is pulling it back

Law #1- The ball stays in motion until the game is over!

Law #2- Have a reminder: Do not use a big marble!

Law #3- Maybe we can point the launcher at a wall, the action is the ball getting hit by the launcher, the reaction is the ball hitting the wall once hit.

Pinball Wizard – Electromagnets

  • That to make an electromagnet, you have 2 feet of wire, then wrap it around a nail, then It will pick something up that is magnet

  • I learned that the amount coils wrapped, the more paper clips you can pick up.

  • In order to make it stick, you can’t just can’t lift it up by you, you have to let it stick to the nails by itself.

  • To make it stick, you may just have to use paper clips. May be it can work with anything that is attracted by an Electromagnet. Some objects attracted to magnets are such as paperclips,  small metal bars, nails.

 

We are thinking of doing, you hook up the Electromagnet to one of the sides of the wood, and if the ball hits the Electromagnet, someone would go in the back and turn on a switch that say game over, so if the ball hits the Electromagnet, game over.

 

Some scientific words for Electromagnets:

  • Coils

  • Magnet

  • Circuit

  • Nail

  • Electromagnet

Pinball Wizard – Making A Bulb Light Up

What did you learn about circuits: That we can make cool things with a circuit. To make a circuit, you need 2 wires, a battery, battery holder, and a light bulb holder.The battery is the source, the path is the wire, and the load is the light bulb. You would connect the wires to the ends of the battery holder, use one wire each for one side. Then hook the ends of those wires to the light bulb holder, and it should light up.

How can you apply the circuit to a pinball machine: You can use a circuit in your pinball machine to say “game over”, or “50 points”.

 

 

Here is a movie you can watch about circuits:

Hope you like it!
