1. What was the best part about the pinball project that I could work as a group and have a lot of fun building it and I made new freinds and that was a lot of fun.

2.  What were some of the joys of working in a group that we worked together and that we had fun and that everyone was included.

3. What wer some of the struggles of working in a group that we would not always listen to eachother and that we would pike one and then one of us would not like it.

4. Goals of group work that we would work as a group and not leave one out and that we would finish it and that we would not try not to finish first.

Marbles on a Ramp

I learned that bigger marbles are faster then little marbles and medium marbles and the more mass = the faster it goes And the results of the whole class was that the big marble took the shortest time and I thot that the little marble would go the fastest.

How can I apply this to my pinball machine

I will make the ball bigger and heavier and maybe get a bigger marble and we can make the pinball higher.

Law #1 The law of inertia

• An object at rest will remain at rest unless acted on by an  unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

  • He put a stuffed animal troll in the toy car and then someone pushed the car and someone held the ruler in place and when the car hit the ruler the stuffed animal troll wanted to keep moving because an object in motion stays in motion and the troll flew forward.

  • For our second experiment if you were on a stool and there was a hole and then a person  pushed it then you would fall into the hole.

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 a basketball. So the basketball will roll faster and longer than a medicine ball.

  • We pushed the medicine ball and the basketball and  the basketball and the basketball normally went farther.

  • We pushed each other on chairs,and we see who was heavier

Law #3 Action – Reaction

• For every action there is an equal opposite reaction.

  • We tied a rope to the walls and tied a balloon onto it and we let go and it went across the rop.

  • A funny part was, when the balloon went out of air, the balloon was covered in tape

    The action is the ball getting hit by the launcher and the reaction is the ball coming and hitting the bouncers and coming back to the launcher

What I Learned about Electromagnets.

• Electromagnets use electricity to power them.

• The more coils on the nail the more power you have.

• It’s like a circuit because you have the source(battery),path(wires),load(lightbulb).

What I learned about the experiment

• Magnets are in living things.

• the earth is a gigantic magnet.

• This force can be created by the motion of electrons.

• Magnetism is a force that electric currents exert on other electric currents.

• Animals use the magnetism to find there when traveling.

How can I use it on my pinball machine.

• To pull the ball into the launcher.

Circuits

To make a circuit you need a battery holder , light bulb holder and two wires and you need a source(Battery), path(wires) and a load(light bulb) then you put the battery in the battery holder and the light bulb in the light bulb holder and then you connect the one wire to one side to the battery and the other wire to the other side of the battery and then you put one end of the wire in the light bulb holder and the other side of the wire in the other side of the light bulb holder and then it should light up

I could put a switch at the end of the pinball machine that makes a game over sign that lights up
