Chemistry Experiments With Water

Question: Help with chemistry experiment?
I need to design an experiment for this project.
Experiment:
You are provided with a mixture, M of two solids. One of the solids in mixture M is soluble in water. Describe how you would carry out an experiment to separate the solids in mixture M and produce a sample of the soluble solid.
Please tell me with steps and the results obtained. Thank you!
Answer: It would seem to me that…
1. Add water to the total solid until it appears that no more is dissolving.
2. Filter off the insoluble solid.
3. Vacuum distill the filtrate until most of the water is removed into the collection flask. You should be left with solid in the distillation flask and a bit of water (NEVER distill to dryness since doing so can cause an explosion). If you need the solid completely dry, let water evaporate for a while (or, boil it off)

Science Experiment For Middle School

Question: Science Experiment Ideas?
I NEED a science experiment , for a competition against the WHOLE state , i have a group of 3 im good with chemistry and my freind is good with biology and my other freind is good with physics.
we were thinking about making a mirror with silver nitrate and sodium hydroxide but we couldnt cos of the guidelines that say
- no explosive, flammable or poisonous experiments
- no cruelty to animals
- no harm to the environment
so i need some good ideas and/or websites
i need the ideas to be bold , new and differant so dont tell me things like making a volcano with bi-carb soda and vinegar or changing flour colours and if you tell me something please try to tell me where i can get the chemical.
im nearly finished middle school.
pleaseee answer quickly. THANKS A TRILLION!
oh and i need it to proove something.
-what
-why
-how etc…

Answer: If I had a dollar for every time this question is asked …
As references, I’ve listed a wealth of sites with a wealth of project ideas. I haven’t checked all the links lately, so some may no longer be valid. Thanks to Former MN Science Teacher for many of them. Check out the past winners/entrants at the scisvc.org site for more difficult projects.
Be creative. Don’t waste this extremely valuable experience by copying someone else’s idea. Focus on what interests you. Choose the best and most interesting project that you’re confident you can accomplish in the time allowed. And allow plenty of time. A really good science project looks very good to college admissions officers, especially if the fair judges agree and award you a prize. You want to show that you can think, reason, manage a project, do proper experiments, write your results clearly and accurately, and that you’re willing to work. Do your own research. Do your own work. Get help and get advice. Teachers and people in industry are often very willing to give advice and to make equipment and facilities available to someone who really cares about their project. It’s a great experience.

Science Experiments Preschoolers

Question: How can I design a better Science Experiment For Preschoolers dealing with flour?
We are going to read a book about cupcakes and then for science I’d like to do an experiment with flour. Without actually cooking anything. Is letting them play with the flour and then mixing in water to see the change enough? Is there anything I can add to it?
Answer: You can make non cooked play dough. It will require mixing but at least you don’t have to cook it on a stove.
Here is a recipe I found
NO – COOK PLAY DOUGH
1 c. water
3 c. flour
1 1/2 c. salt
1/4 c. oil
Food coloring
Combine ingredients in bowl and mix. Add more flour if mixture is too sticky. Store in a plastic zip-lock bag.
