Wavelength and Frequency


In our physical science class, we learned about light and how it acts like a wave. but how do we know? We also learned how light reflects off of waves and how the colors we see reflect off of the cloths we wear. Like a blue sweatshirt is in reality everything but the color blue. So it reflects a blue light. Light is also a specific kind of wave, also known as electromagnetic radiation. we also learned that while sound waves and all other waves need a medium light does not.

Light Reflection And Reflection

Reflection happens when a specific color reflects off of a specific object such as blue reflecting off a shirt. This is why blue reflects off of a sweatshirt as i said earlier. Im pretty sure the prject we did for this was cancelled.

We started the project by starting a small poster to show what our future project would look like. in my first group we made a pulley system and a series or ramps, axels, and wheels. In my other group they had a wheel and axel, dominos as a lever, and a small pulley system and a  ramp.  The goal of this was to pop a balloon, which we succeeded in.After we also did a blueprint, while Damien drew the poster I weighed the balls and got a measure for everything and stated the mechanical advantages.
 The goal of our rube Goldberg was to pop the balloon which was on the floor of the phys science room. To do that we would need a system of ramps bringing a ball to the floor hitting a car with two tacvs on the front hitting the balloon and causing it to pop. We had the wheel and axel system hit the dominos and after the dominos hit each other they collided with the ball making it fall through a cup with a hole in it. The ball hit the dominos below. The dominos hit the car making It go down a ramp. The car then proceeded to hit the balloon and POP.
Damien was the real mastermind of the plan, he came up with the car with tacs attached popping the balloon. Nick did the construction, I helped near the end with the dominos and weight measurements and the mechanical advantages. That was how we did our rube Goldberg machine.

Simple Machines Rube Goldberg

Rube Goldberg was born in 1888 in San Francisco I don't know why my typing is dark like this by the way. He was well known as an author, an engineer,  In 1900 he graduated from Lowell High School in San Francisco and in 1904, he graduated with a degree in engineering from the University of California, Berkeley. his cartoon strips made him a very popular man. he also won the
 1948 Pulitzer Prize for his drawing about the world being on the edge of nuclear devastation, and has received several awards from the National Cartoonists Society including the Gold T-Square Award in 1955, the 1969 Rueben Award and the Gold Key Award, after his death in 1970. To further add to this list of accomplishments, he won the Banshee's Silver Lady Award in 1959, he was a co-founder of the Famous Artists School , President of the Artists and Writers Club and a member of the Society of Illustrators.

newtons law questions

1. What are the relationships between forces and motion?
The relationships between forces and motion is the newtons laws. The newtons laws often involved an object in motion staying in motion. unless acted upon by an outside force. This shows how forces and motion have to intertwine  or else objects would just stay in endless motion. That is the relationships between forces and motion.



 2. What are the variables that affect motion and force?
 the variables that effect force and motion would be gravity. Gravity because it causes friction and thus is an outside force affecting the motion and force of the object. This of course would also count frtiction as a force of motion and thus is also an effecting variable. BOOM

3. How does Newton’s three laws describe the motion of a moving
object?
 That an object in motion should tend to stay in motion. That an object also in motion tends to stay in motion unless activated by an outside force. also that an object that is not in motion will stay still.

4. How does gravity impact objects?
 gravity causes friction within the objects and the force. this causes the object to slow down. This labels them as an outside force which makes the object stop, also gravity pushes down on an object.

lab report race car thingamabob

                           


at the start of the experiment we set up a board at an angle which allowed us to race the cars at a downhill angle. after we raced the car without the weights we added weights starting with a small weight, moving to a larger amount. After we reached the maximum weight we graphed the equation and we found that the friction increases with the amount of pressure and mass added on by the weights which caused the car to slowdown.  we then answered some questions and graphed the equation

museum of science field trip.

       





our physical science class recently took a trip to the Boston Museum of Science. this blog is an overall review of our experiences and what we learned about friction, movement, and electricity.

    while we were in the museum we saw the Fantastic Forces Presentation. which was meant to educate us on the laws of motion, and friction. we observed the forces of movement take place, for example we saw a pressurized pencil going at 100 miles per hour go through a block of wood. I also l learned that Newton was the scientist who figured out gravity. even though in my opinion everyone already knew what happens when an apple falls out of a tree. he just gave it a name.
  
shortly after the presentation we went to see the rolling ball sculptures which was made by George Rhodes not just for Boston, but for other museums as well. however, the ball, driven by gravity drops down triggering several musical instruments. for the most part however, the ball just went down because it was driven by the forces of gravity. which caused the ball to go down which triggered the instruments making several sounds and noises. that was all of the sculp0ture.

    after that we went on to a class on engineering and we built bobsleds. my bobsled got a time of 1.36 seconds which was one of the fastest while albert won with 1.33 seconds. my bobsled had a leopard print kind of cloth on top of it. it also had two batteries to make it go faster. I ended up not naming it because I don't like naming thing after we completed the engineering course we went to see my favorite part of the museum,.

we saw the electric show. it showed us how powerful electricity really is. they used electric pulses to make the musical notes from star wars, and other musical numbers. they also used electricity to make peoples hair rise and explained to us what to do in a lightning storm. then for the finale the scientist who was running the whole thing went into a completely metal cage. then he mad the cage be electrocuted with what I can only imagine to be hundreds of thousands of bolts of electricity. that was the conclusion to the experiment and really to the field trip.

during our chemistry science of life studies i learned about how proteins have to build up muscle in the human body. we also learned about how lipids are fats and waxes. carbohydrates produce energy. and nucleic acid increases your skin health.
