I think it's the one

I think I am going to do the experiment on the strength of different metal wires and I've got the okay. Roughly, what I've decided to do is get 50cm lengths of different wires, e.g. copper, steel, aluminium and zinc and I will hang them all up at the same place. I will then add weights to each of the wires and measure the expansion for each to determine which metal has the least expansion and is the strongest. I will repeat the experiment 3 times and show expansion as a function of weight (line graph). I think that this is very useful information as wires are used a lot to bear mechanical loads. The independent variable in this experiment is weight and the dependent variable is expansion. All the materials that I need are easy to get and I think it should be a reliable experiment.

some ideas

Ok so I did have a few ideas. One plan was to do the expansion of different metals when heated but I can't do that one because the expansion is too small to be measured. The independent variable there is the heat and expansion is the dependent variable.

I thought about a few other ideas too and did a bit of research. I wanted to build a solar powered fan and I did the research and it's possible but it is not the best thing to do because it's a bit difficult but it would make a good long-term project so I'm thinking about it. It wouldn't be an experiment but it would be the developing of the actual fan and building it. I think that would be fun but I would like to do an experiment. The materials for that experiment are a bit dangerous, like a soldering iron so that's another negative. Also, there are not really variables because it isn't an experiment.

I found another experiment I could do. It is to observe the effect of light on plants. The independent variable is amount of light received. The dependent variable is growth of plant. I think that this idea is fairly common though.

Another idea is how plants grow, as in, the direction that they grow in, relative to where the light is from. The independent variable is where the light is from and the dependent variable is what direction the plant grows in. However, again, I think that this idea is fairly common.

I AM KEEPING THIS BLOG VERY ACTIVE.
see here's another post. i think i deserve full marks for that section :D
yeah so i thought about it a bit more and I think I can do the experiment testing strength of different metal wires.
I'll get some wires made of different metals, all of the same length and some little weights and then ill add the same amount of weights to each type of metal wire and see which snaps first and I can probably time how long it takes too if that's necessary. i like the metal expansion one too but I'm not sure if I can do that one. Will seee.....

some ideas... (first post)

i checked my email and i see that i was supposed to post a first post so this is my first post.
ok well, i should post something so im going to do that now...
well, i HAVE been thinking about what to do. my first idea to make happy pills was rejected (thanks Miss Zhang) but yeah...i have a few ideas. I've been thinking about doing maybe expansion of different metals when heated or strength of different wires (like different metals). i think im going to do the second one if i can.
