Now that I've found a good SRP topic: To test the evaporation of water using different plastics for cover, hopefully this experiment will work. I know I'll have to conduct it more than once to make it a fair test, because things may not go well the first time. I need to go shopping to buy the different plastics, and find 5 same containers. I may as well use take away containers, I have tonnes of them. I'm glad because I'm also curious how this experiment will turn out, and it can easily be done at home. I have all the materials I need, except the plastic, which I can easily get at the supermarket. Yay!

But for now, let more creative juices come!

okay, I've finalised this!
I'm going to do:

What type of plastic wrap prevents evaporation best?

Okay well, not that I got that out of the way I can set up everything I need.

Aim: To investigate which type of plastic wrap prevents evaporation best.

Hypothesis: The thinner the sheet of plastic, the more the liquid will evaporate.

Equipment: 5 different containers, 5 different brands/sheets of plastic.

Method:

1. Pour 250mL of water into container
2. Cut out a 30cm x 30cm sheet of plastic.
3. Place plastic over the container and securely wrap it around all edges
4. Wait 4 days
5. Take off sheet of plastic and measure the amount of water left in container
6. Record observations
7. Repeat steps 1-6 with different plastics

Okay, after discussing it with a few people, I've decided choose from either
'What type of plastic wrap prevents evaporation best?'
How permanant are 'permanant' markers? What will dissolve the ink?


I narrowed it down to these two because these ones in particular because they would go over for a couple of days, maybe even a week or two and that is exactly what I want.

For the first one:
Independant variable: The number of days the plastic wrap stays over the container.
Dependant Variable: The type of plastic wrap.
Controlled variable: The length of the sheet of plastic and the amount of water/liquid.

For the second one:
Independant variable: The amount/types of liquids that goes on the sheet
Dependant variable: The different markers.
Controlled variable: The amount of writing on the paper.

I have a feeling I'll stick with the first one actually. The second one doesn't sound like it'd work out very well.

I got some more new ideas, but they're all a bit weird.
Do frozen seed sprout?
What type of plastic wrap prevents evaporation best?
How permanant are 'permanant' markers? What will dissolve the ink?
Is a seed affected by its size?
Does the amount/absence of light spoil food slower/quicker?

Okay now I think I have enough ideas to get me started. Now, I just need to finalise them and pick the best one that I'd enjoy the most. Hmm... What to do what to do?

This is my science blog, and I'm totally at loss of what to do. There are so many ideas floating around but I don't know what works best. I don't even know if they are all science related. I just know that the experiment we conduct or what we're trying to see has to involve a change.

I've talked with a few people and they all have interesting ideas. I kinda see what previous students mean by 'Don't leave this till the last minute', cus it's quite frustrating. In fact, don't leave anything till the last minute!

I've come up with only a few so far:
How fast do fabrics burn?
What type/brand of chewing gum sticks the longest onto different surfaces?
The absorption rate of different paper towels

That's all I have so far, and I don't know which one to work on. I'll also think up of a few more over the next few days... or hours.
