Scientific Summer

Scientific summer

Think about something you did this summer that was scientific. Write a paragraph to describe what you did. Be sure to give some detail of your activity.

This summer I went to Kennedy space center. I know this is part of science because of all the materials they used to make NASA work, the rockets, the moon, and earth everything to do with science. In NASA we got tours around 3 places, one of the places you could see the place where the rockets take off, I also saw the main engine of a rocket, I saw the rocket that landed there in 2011, I saw the lading lane. I saw the BIG HUGE rocket. I saw the poles that fall back to earth after the rocket is about to touch space. I also did touch part of the moon. We also where in the control center.

Write a second paragraph to explain what is scientific about what you did. Give an example and put some detail into your explanation. Refer to science concepts (Newton’s 2^nd Law, gravity, electricity, blood flow, etc.) and give a short lesson if you want.

I think that this was very scientific. We learned about how the people feel and how hard it is to go to space. This had a lot to do with gravity, electricity and much more scientific stuff.

Make an impact!!!

Guiding Question: What are the factors that affect the appearance of impact craters? How do scientists use craters to tell the relative age of them?

Hypothesis: I think that the higher the marble is to be dropped, the deeper the crater is.

Data Analysis: The higher we put the marble the deeper the crater was. The diameter also also got bigger. When we dropped the marble from 200 cm the depth was at least 1.4 cm and the diameter was 2.6.

 

 

 

Moon Phases

Reasons for the Seasons

Guiding Question: How does the tilt of Earth’s axis affect the light received by Earth as it revolves around the sun?

Hypothesis:


Monica’s: I think that when the light of the Sun is shown on the earth, it will spread out, so that the North Pole sometimes doesn't get light, while the South Pole does.

Skills Focus: making a model, observing, inferring, predicting

Materials:

• books
• flashlight
• paper
• pencil
• protractor
• toothpick
• acetate sheet with thick grid lines drawn on it
• plastic foam ball marked with poles and equator

Producer:

1. Make a pile of books about 15 cm high.
2. Tape the acetate sheet to the head of the flashlight. Place the flashlight on the pile of books.
3. Carefully push a pencil into the South Pole of the plastic foam ball, which represents Earth.
4. Use the protractor to measure a 23.5° tilt of the axis of your Earth away from your ‘flashlight sun.’ This position represents winter in the Northern Hemisphere.
5. Hold the pencil so that Earth is steady at this 23.5° angle and about 15 cm from the flashlight on. Dim the room light.
6. The squares on the acetate should show up on your model Earth. Move the ball closer if necessary or dim the room lights more. Observe and record the shape of the squares at the equator and at the poles.
7. Carefully stick the toothpick straight into your model Earth about halfway between the equator and the North Pole. Observe and record the length of the shadow.
8. Without changing the tilt, turn the pencil to rotate the model Earth once on its axis. Observe and record how the shadow of the toothpick changes.
9. Tilt your Earth 23.5° toward the flashlight. This is summer in the Northern Hemisphere. Observe and record the shape of the square at the equator and at the poles. Observe how the toothpick’s shadow changes.
10. Rotate the model Earth and note the shadow pattern.

Noise Pollution

Noise pollution

Noise pollution is a type of energy pollution in which distracting, irritating, or damaging sounds are freely audible. As with other forms of energy pollution such as heat and light pollution, noise pollution contaminants are not physical particles, but rather waves that interfere with naturally occurring waves of a similar type in the same environment.
Noise pollution can affect us in many ways. It can cause hearing problems, cardiovascular issues, sleep disturbances, interference in verbal communication and mental health problems. Noise levels above 80 decibels produce damaging effects to the ear. When ear is exposed to extreme loud noise above 100 decibels for a considerable period of time, it can cause irreparable damage and lead to permanent hearing loss. For example: when I was small I was in kindergarten and I had to be operated in the left ear. A few years ago (3-4) I had to be operated in the right ear (this is true).
There are a lot of issues and problems with noise pollution. Most disagreements and arguments are between neighbors. For example, when you’re going to have a party, you should at least worn your neighbors that you will be having a party, and at what time it will start, and at what time it will end. You also must tell your neighbors if you’re having the party outside or inside. If you are having the party in the yard/ garden, don’t forget that sound travels much easier outside then inside. Better still…….why not invite the neighbors? If you are working in the house, make sure not to start to early, maybe around 8 am, and don’t try to work later than 8 pm. This might be better to do on weekends, because some neighbors have children and they have to go to school. On weekends most of them are at home, or at friends (etc). Just be sure to keep the sound in control, because some people might be sick too. Especially when you live near a hospital.
Science can be involved in this in many ways. Science can help find other resources which don’t make so much sound. You your self can even think of a way to help the environment be better. Technology is kind of the same. Technology can help change the material of a thing you’re using, or the sound. For example, I’m writing this essay right now and I can’t really concentrate. I hear motorcycles outside, cars, people building things and so on. This is kind of like noise pollution.
I think since and technology has helped us a lot. But something’s are not working out as well as we thought they would with our world/earth. Us people try as hard as we can to solve problems, but sometimes problems can’t be solved. Noise pollution has been a problem to some people. Like the deaf, or people who are about to be deaf. Noise pollution is something that we COULD stop, maybe, but we are not trying hard enough. We have to do something to help people to overcome these things.
