Life Waves

Wavelength and Frequency:  Light is a very interesting thing. Light is actual a wave. The light we see is called a electromagnetic radiation. Also light does not need a medium like sound waves. This is one of the reasons electro magnetic waves are so different from other types of waves.

1: waves go up but always back down to the original spot. 
2:Starts next to the hands and goes out.
3:The initial compact has the highest pitch and then its lower from there out. 


Exploring pitch and volume:


1: The wider the inside of the glass the lower the sounds.
2:Higher pitches have a shorter wave length. 
3:Higher frequency to higher pitches. 
4:More echo with lower pitches.
5:lower pitches come out after impact, higher pitches almost immediately.
6:High pitch sounds have a more steady downfall, low have more of a drop.

Rube Goldberg reflection

Making a Rube Goldberg is a pretty tough task. My group started making it with dominoes and a ramp but some other group kept taking them after our class. As a result we had to start over about 5 times. We've been assigned a different assignment. My group has to make a simple machine board game. We are making good process and have finished making the board and only have a few questions to write left. We also have to color it and then well be done with our project .

6 Simple Machines

"Rube" Goldberg was an American cartoonist, sculptor, author, engineer and inventor. His cartoons showed people tasks with unecessary amounts of effort. 

Pulley-a simple machine that uses grooved wheels and a rope to raise, lower or move a load.

Lever-  a stiff bar that rests on a support called a fulcrum which lifts or moves loads. 

Wedge- an object with at least one slanting side ending in a sharp edge, which cuts material apart.

Wheel and Axel- A wheel with a rod, called an axle, through its center lifts or moves loads.

Inclined Plane-  a slanting surface connecting a lower level to a higher level.

Screw- an inclined plane wrapped around a pole which holds things together or lifts materials.

newtons laws

1. What are the relationships between forces and motion? the relationship between forces and motion is that force =mass X acceleration. The acceleration is the motion. the faster something goes the more force it has.                                                                    
2. What are the variables that affect motion and force? the variables that affect motion and force are mass, gravity, friction, and others. 
3. How does Newton’s three laws describe the motion of a moving 
object? It shows how mass affects speed, how speed affects force, and how every action has an equal and opposite reaction
4. How does gravity impact objects? gravity makes object heavier which makes them slower which makes it have less acceleration which makes it have less force

Museum of Science

Fantastic Forces
                   Fantastic Forces was a great presentation. I learned a lot of new things. The first thing I learned is that an object in motion will stay in motion unless acted upon with another force and that a stopped thing will stay stopped unless acted upon with force. The only thing that stops anything is friction. Even if it is in the air the air surrounding the object will cause friction and slow it down. I also learned that force=mass x acceleration.

Engineering Design, Bobsled Activity
                    This was probably my favorite activity we did at the museum. We were told that we had to make a replica bobsled with a base fabric and 4 batteries then we could add any extra stuff for weight if we wanted to. I noticed that the more weight you put towards the front the faster the sled would go. Also the type of fabric you chose was key.    At first I had some bumpy grippy fabric which made my bobsled go extremely slow It wouldnt even make it down the ramp. Then I switched the fabric to a smoother one with less grip and added as much forward weight as possible and the sled went a lot faster.


Lightning Show
                   The lightning show was also a great presentation. We all learned a lot about electricity and lightning. I learned that even though the lightning was loud and bright electricity is usually invisible and silent. Which is one the biggest reasons why it is so dangerous. Since you can't see it electricity can be hard to escape. I also learned that the surface of lightning is hotter than the sun.

Archemedian Excogitaion Audiokinetic Sculpture

                   This was a a very interesting sculpture I notice that it went up only once. The rest of the time it was just let gravity take it down. The whole way down it was playing instruments

Chemisty is necessary for us to survive. Different compounds allow us to do different things.Protein allows us to build muscle and do movements. And others allow us to different things.
