Journal Entry 4

Complete the following reflective journal questions on your edublogs account.

1.     What did you like about this project?

I liked the fact that the whole project was based around the practicals that we completed, which made it easier to organise the project.

2.     What did you not like about this project?

The thing I didn’t like, were the research sheets we had to complete, I think it wasted our time on the actuall project.

3.     Suggest 3 ideas that could improve/make this project more engaging.

One idea would be to, as said before, to not give out those sheets, right before the project is due, Another is to make the project more web based, and finally to probably give out more practicals that are fun, and engaging.

4.     Did you like the driving question? Explain why/why not.

Yes, as it was clear, which made it easier to understand what we actually had to do.

CONCLUSION:

From the experiment that we have conducted, we can conclude by saying that each test pointed out what occurs when two tectonic plates collide, as the tests also proved what happened in all sircumstances what would happen as each test reacted differently and showed the following collisions, such as, a continental plate with another, an oceanic plate with another, and a continental plate with an oceanic plate.

CONCLUSION:

We can conclude by saying that, when the crystal potassium pertanganate was entered into either the hot or cold water it reacted by creating a convectional current, a different current for each tempreature that it was placed in, as when it was placed in the hot water, the crystal created a circular current, in which it spread around the water, rather then when it was placed in the cold water it created a totally opposite current, which made the crystal give-off sink. These different currents are due to the different densities of the water.

1) Likes and dislikes of this project…..any suggestions on how to improve???

1.     Likes:

The things I liked in this project are such as, creating a prototype of an optical instrument, and the fact that everything was computer based.

2.     Dislikes:

The thing I disliked the most was that I found that there was insufficient time to complete a proper cross-section of an optical instrument. A way to improve would be to give us more time.

2) What areas do you think you have improved in from project 1 to project 4?

From projects 1 – 4, I think that I have improved in many areas, such as:

·        In using and being able to properly search on the internet.

·        Being able to work scientifically in a group environment.

·        Presenting to the rest of the class and other people.

·        And more…..

3) What further skills would you like to develop over the next few projects?

I would like to develop and improve in skills that I have started to pick up, in the following areas:

·        In using and being able to properly search on the internet.

·        Being able to present even better then how I am now.

·        Learning how to use different scientific tools

·        And more….

1. Analyse why red sunsets can sometimes be more impressive when there is more dust or pollution in the air than usual. From the colors that make a white light, the two colours that have the longest wavelengths are red and orange, which means that they are least likely to be deflected, So dust and other particles, in the lower atmosphere will scatter out the sun’s blue and green light, leaving just the red, orange, and yellow light to survive, creating a sunset. However, pollution, forest fire smoke or even volcanic ash can scatter light even more, leaving just the red light to survive and creating a very impressive red sunset.

       2.  Describe what happens inside water droplets to cause a rainbow and explain how you can tell whether a rainbow is a primary or secondary.

   As sunlight enters water droplets in the atmosphere, its ‘constituent colours’ or wavelengths are refracted in slightly different amounts, while passing from the air into the water. A portion of the light striking the back of each water droplet is internally reflected and then refracted a second time as it merges into the air again. The colour that is refracted the most is Violet.

1. what causes the defect?

• Short-sightedness occurs when the focal point in the eye drifts away from the retina.
• Long-sightedness occurs when the focal point drifts behind the retina.  

    2.   the symptoms displayed.

• Close objects appear fuzzy or blurry, while distant objects remain in focus.
• Headaches or tired eyes. In young people with long sight, the eyes can still focus on near objects, for example when reading a book. 
• Squints.

     3.   propose what sort of lens may be used to correct each vision.

• Short-sightedness could be corrected by using glasses that have concave lenses so that the focal distance will increase in your vision or sight.
• Long-sightendess could be corrected by using glasses that have convex lenses so that the focal distance will decrease in your vision or sight.

Investigate how jocelyn bell burnell discovered pulsars in 1967. Write a short account of this event.

Jocelyn Bell Burner attended Cambridge university, and during her first 2 years there she was assisting in the construction of an 81.5-megahertz radio telescope that was to be used to track quasars (A distant energy source which gives off huge amounts of radiation, including radio waves and X-rays). The telescope went into operation in 1967, and It was Jocelyn Bell’s job to operate the telescope and to analyze over 120 meters of chart paper produced by the telescope every four days. After many weeks of analysis, Bell noticed some unusual markings on the chart paper. These markings were made by a radio source too fast and regular to be a quasar, instead she had detected the first evidence of a pulsar.

1. What do you think the pheonix will find?

I think the pheonix won’t really find anything that hasn’t already been discovered by other space probes that have landed on the surface of Mars.

    2. Do you think as a planet we should be researching other planets? why?/why not?

I think we should, so if something in our galaxy that will cause total destruction, such as the sun blowing up, it will most likely to effect our planet earth, but if we were able to research other planets, we could be able to decide whether or not other planets are able to sustain human life, so that we are able to move to that planet and prevent being blown up along with the sun.

-         What was Hubble’s involvement in space research?

Edwin Hubble’s involvement in space research was that he had discovered, and was the first man to show that the universe was indeed expanding.

-         What does the telescope do?

The Hubble Space Telescope is a powerful orbiting telescope that provides a clearer and sharper image than other telescopes do. It is a reflecting telescope with a light-gathering mirror. The telescope is named after American astronomer Edwin P. Hubble, who made fundamental contributions to astronomy in the 1920’s.

Astronomers have used the Hubble Space Telescope to obtain images of celestial objects and phenomena in the universe, that is in detail never before observed, These include pictures of stars, and more…………………… 

-         Where can the telescope be found?

The hubble space telescope can be found just above the earth orbiting it, while collecting high detail images.

-         What is Hubble’s law?

The observation that any two distant celestial objects (e.g., galaxies) move away from each other at a speed v that is proportional to the distance d between them, due to the homogenous expansion of space. v=H₀ * d
