Question: What are the best plants to use in a science Project?

I am doing a science experiment for highschool biology , and I was wondering what was a fast growing plant that flowers and grows tall in a short matter of time that would give accurate results.Thank you

Answer: I say use any type of bean seed.
Bean plants are good as beginner plants, and flower pretty quickly if the temperature is right.

Question: How much calcium carbonate is there in limestone ?

I have to do an experiment for school (for chemistry more specifically) and have to do the research ourselves. I want to know how do you find out how much calcium carbonate is there in a limestone. What are the apparatus used and what is the procedure ? I need this info to write up the lab report. Any help will be appreciated.

Answer: While the first answer is essentially correct, limestone IS calcium carbonate, it is NOT pure calcium carbonate. most limestones contain other materials such as magnesium carbonate and silica. You can measure total carbonates by titration with an acid such as HCl. Alternatively, you can dissolve the limestone in a strong acid such as HCl or H2SO4 and then determine any residue left by weight.

Question: Very advanced science experiment ideas?

Does anyone know of any really advanced science experiment ideas? It could also be a research project. It could be chemistry, physics, electricity, etc..

something like what happens with Potassium chlorate and candy. Something hard that won’t kill you

Answer: For really advanced ideas, check out the second site and look at the topics of previous entrants/winners.

The other sites might also give you some ideas.
