The aim of the experiment was to see the movement of of convection currents. We found out that when the water temperatre was hot the pottassium moved around in a circlar motion while when the water temperature was cold the pottasium just sunk and fell to the bottom of the beaker.
1. Likes and dislikes of this project…..any suggestions on how to improve???
I liked the fact were we weren’t restricted to a certain method of presentations. I disliked all the journals. We should have less journals and more help on them.
2. What areas do you think you have improved in from project 1 to project 4?
Presentation skills have improved, computer skills have improved, PBL methods have improved and basically everything is slowly getting better.
3. What further skills would you like to develop over the next few projects?
I think that I need to improve my presentation skills also researching things more throughly than I have been doing.
Investigate the two types of sight defect- long-sightedness and short sightedness.
Find the following information:
Long sightedness
a. what causes the defect
Long sightedness has many different causes with the main one being generics. Other causes are diabetes, microphthalma.
b. the symptoms displayed
The main symptoms of long sightedness are persistent headaches, eyestrain, excessive blinking and dislike or avoidance of reading.
c. propose what sort of lens may be used to correct each vision.
The lens is a convex lens. A convex lens is chosen because it moves the image of a distant object forward onto the retina.
Short-sightedness
a. what causes the defect
It has a wide range of causes. The main ones are genetics and also sitting close to the tv.
b. the symptoms displayed
The main symptoms are squinting and eyestrain.
c. propose what sort of lens may be used to correct each vision
The type of lens that is needed a concave lenses because this will suit the needed requirements.
What did you like about the wikispaces project? Explain.
The wikispaces project wasn’t bad. It was a bit boring just uploading all of the work to wikispaces and not using much of our computer skills.
What did you NOT like about the wikispace project? Explain.
That we didnt use much of our computer skills.
What did you find hard about working in groups?
Sometimes you get people that dont do enough work. Also sometimes you have to work with people you do not get along with, but now im getting used to it a bit.
How did the wikispace keep everyone in your team accountable?
With the wikispace, when you upload yout work and edit page, the wikispace has a history. So you can tell if someone didnt do there work and you can message them using wikispace.
How could you improve your presentation?
We could of been more organised with our powerpoint and our speech. Also practise as a group a few times before the presentation.
JOURNAL ENTRY 1
THE HUBBLE SPACE TELESCOPE
Research and gather information from the internet about the Hubble Space Telescope. Use the following questions as the basis for your journal entry:
What was Hubble’s involvement in space research?
He cerated a very important resource which is the telscope and this has helped space significantly.
What does the telescope do?
The telescope is a instrument designed for the observationof remote objects like planets.There are many different types of telescopes aswell to cover different ranges.
Where can the telescope be found?
In the earths oribit.
What is Hubble’s law?
Hubbles law is about the distant stars and glaxies were reeceding from us, and that the further away they were, the faster they were going.
