my awesome Marafiki here, help.

I dunno? Covalent bonds? au wewe could always measure the growth rate of something. au if all else fails, wewe could always resort to the basic baking soda volcano.

Okay, the truth is, I don't know what level of science (or what type) that wewe are in, so I couldn't possibly help wewe without zaidi information.

wewe could do it about the heart,the body,plants,the spectrum,electricity,water,atomic structure...

Okay, so I did a science project that didn't take much effort.
The project was called "Which Type of Potato Will Rot Faster Outside, Sweet au Regular?" wewe can guess what it was about.
I made it up because I was literally about to lose my mind. I COULD NOT decide on a topic. It was frustrating. This one is super boring. Nobody cares which potato will rot faster outside!
I got an A+ anyway XD

Why not try biotechnology,it includes DNA CLONING,BIO REMEDIATION,MANUFACTURE OF SO MANY PRODUCTS AND LOTS MORE!u will tons of info on the net,libraries,science articles.moreover this is a very interesting topic:)

This is going to sound so... old (as in age old, not did so many times it became old, but I digress [or however ya spell it])

Anyway, back on topic. wewe need to do something that wewe will remain at least halfway interested in. (I'm not a science girl, can't stand the subject) That being alisema I did my science presentation on the effects of Photosynthesis. wewe know, how a plant reacts if placed in direct sunlight vs partial shade vs complete darkness. It was somewhat interesting and I got a B. I was proud, but I'll tell wewe the most interesting project at my school during our science fair. Can't remember what the project was called, but it featured an aquariam filled partially with dirt and water and held frogs, moss, salamanders, etc. The project started with a "T". A terrarium, I think. It was cool. Got a good grade too.

how electric currents work?
