Hi this is Bertram and this is my Post. My Machine is called " Kalashshikoff " which is AK47's "K". My machine looks like a tank it has a flame thrower ( bundle of wires ) and a cannon ( -knife switch ). My machine could churn your finger off when it is in the air and it is useless if on the ground so my time was N/A. Well I have eight pictures and ten videos......SO ENJOY!

This is my car

I am going to tell you about some simple machines
pulley:a rope attached to a wheel that makes heavier things easier to lift
wheel and axle:a stick going through the middle of an axle
lever:a rock or something big and heavy is below a wooden stick to lift a heavy thing
gears:a wheel with tiny points on the side to make other gears move
Inclined plane: an uphill slant

Here are some cool web pages about simple machines

Here are some videos of simple machines put together

Now here are my race results

name race time
Keiichiro flat 2.99 sec
Bertram flat n/a
Gareth flat 5.34sec
Satoshi flat 5.72sec
Ben downhill 3.95 sec
Albert flat 2.88sec
me flat 13sec (there was something wrong with the timer)

Thats all for now see you next time

The Ben Show-Machines

Hello and welcome to the Ben Show. I know there is really no such thing as the Ben Show but I couldn't think of anything else. You might also want to know that the picture to your left is from dvice.com.This season's topic is machines, and boy, are there a lot of machines in this world. I bet if you walk along any modern street on a regular day in a regular place, you will see at least one machine. There are two types of machines, simple machines and compound machine. Learn about simple machines at http://www.mikids.com/Smachines.htm and read about compound machines at http://library.thinkquest.org/CR0210120/Compound%20machine.html or play a compound machine game http://www.edheads.org/activities/odd_machine/. Also, you are probably wondering why I have the picture of the vehicle. That is because we did not only learn about machines, we made our own cars and raced them in one of three categories, uphill, SUV, and speed. The results were as shown:

Uphill:

No entries

Speed:

Keiichiro-Angri Car-2.99 seconds
Gareth-5.34 seconds
Satoshi-5.72 seconds
Albert-2.88 seconds
Julius-13.00 seconds

SUV:

No entries

Also, due to the use of gears that required more powerful batteries, Ms.Nelson had to make a special race for me and Bertram who used gears in our machine. But due two the fact that both of us had technical difficulties. The results were as shown:

Ben-n/a

Bertram-n/a

NOTE: This does NOT count as a type of race, it was basically speed with better batteries.

We also learned about other things such as electricity, friction,acceleration, and gears.

Here is a youtube video about simple machines working together:

Albert's cool machines!

Hi, my name is Albert and welcome to my website. I am making a car in machine mania and on this site, you can find lots of info on machines.

The History of machines

Even before the 1800's, there were billions of ideas for machines, some were even made,but machines didn't really catch on until the 1800's. Some of the machines made that year were generators and motors and other stuff. But, products that use electricity didn't start until the 1900's.

Simple Machines

There are lots of machines, but the most important ones are simple machines, every machine is made of them. Some have one or more and are called compound machines. The main simple machines are levers, wheel and axle, pulleys, inclined plane, wedge and screw.

Here are some videos of simple machines in action:

Here are some experiments we did.
1.
What you need:
a bicycle pump,
a bit of alcohol,
a bottle.
What to do:
step one,
put the alcohol in the bottle,
Step two,
hook the pump up to the mouth of the bottle,
step three,
pump 10 times.
watch and look what happens.
2
what you need
aluminum foil 6 in. by 1 in.
a battery
What to do
put the aluminum foil at the ends of the battery
hold for 20 seconds
run for cold water.
Here are the race results.
Name time race
Albert 2:88 flat
Keiichiro 2:99 flat
Gareth 5:34 flat
Satoshi 5:72 flat
Julius 13 flat
Ben 3:95 downhill
Bertram N/A flat

Note:the times are in seconds

Here, you can play rush hour.

Satoshi's machine

The oldest machine ever invented was the sewing machine. Nowadays, the range machines is from jumbo jets, to a apple Notebooks.
Click the highlight below to go to a website that has lots of information of machines. http://www.usoe.k12.ut.us/CURR/Science/sciber00/8th/machines/sciber/intro.htm

Experiment 1

What you'll need:battery, 2 wires, light bulb holder with light bulb.

Stick the light bulb to the light bulb holder. Stick the two wires to both sides of the light bulb holder. Stick again the two other end of the wires to the positive and negative side of the battery. As you watch, you will see the light bulb go on. If you let go of the wires on the battery, the light bulb will go off. So you have made a battery switch.

Experiment 2

The hot experiment

What you'll need: a battery and foil.

First you need to cut a strip of foil (6-by-1 cm would be best) then put one end of the strip of foil to the battery and put the other end to the opposite side of the battery. When you hold the battery with the strip on for 20 seconds, the battery becomes very hot.

Experiment 3

The static tester

What you'll need: Silk, clay, paper, straw , pencil and a ruler. Fold the paper in half and while you're at it stick the clay to the rubber end of the pencil. Next, put the clay with the pencil on top of the desk so the pencil will stand. Next, fold the paper in half and balance the middle on the point of the pencil. Then, you rub the straw, pencil and what ever you find in your room with the silk, then put the thing you have close to the piece of paper balanced. then see what happens.

Results: If you used plastic, the paper will move closer to the plastic. If you used metal nothing will happen.

Here are cool machines to watch!

This on is the one I think is the best because everything they use in this machine is from a Honda.

Here's a game to play!

Here's the results from RACE DAY!!!!

Albert: Speed time 2.88
Bertram: Speed time n/a
Keiichiro: Speed time 2.99
Ben: Speed time 3.95
Julious: Speed time 13
Gareth: Speed time 5.34
Satoshi: Speed time 5.72

These are pictures and videos of the race.
