Question: Are there any good ideas for science projects for middle schoolers to do?

Hi! I’m in a science club at my local high school, I’m supposed to supervise children in doing fun Science Experiments, its middle schoolers this month. So what should I do?
These little science projects are supposed to be 1 hour long at maximum. But the most important thing is that it has to be interesting or cool.. whatever way you phrase it.

Answer: Hey, I just did a Science Major and I have heaps of ideas since I did 2 weeks research for projects. Here are a list of the best projects:

1. Effect of electromagnetism (magnetism or electrical fields) on plants. i.e. use magnets with a test plant and none for control and see which one grows better.
2. What depth of seed planting is best for plant growth.
i.e. show which depth seeds should be planted to yield the highest plants.
3. Elasticity of objects at different temperatures.
i.e. Use a rubber band & test.
4. Best detergents.
i.e. Coke is a good detergent in cleaning clothes, try other detergents/chemicals.
5. Energy transformation
i.e. changing of energy types, i.e. kenetic and magnetic to movement (that is how a battery works.)

Those are the good experiments. Remember don’t ever try and look for complicated experiment ideas, instead find ones that you can do realistically and a thorough report on even if it is simple and one that you can record much results on. For instance plant growth.

Question: How do I make my experiment to fit my pupose for my science fair projct?

The purpose is – how does embouchure affect the pitch and the sound spectrum in a low brass instrument – I don’t know how to design an experiement that could test my hypothesis which is – If the embouchure is tighten, then the pitch will be higher and the sound spectrum will fluctuate at a faster rate – I know what will happen but I need to be able to prove it.

Answer: It sounds like you need some way to measure pitch and graph the wavelength. An oscilloscope would do the trick. See if you can find a free software version that will take simple sounds and graph them for you.

Question: can you please help me with my science project?

i need to answer the following questions for my science project

Problem…what are you trying to figure out? Write this in a form of a question

Hypothesis…what do you think you are going to find out?

materials…what materials will you need to complete your science experiment?

procedures…make a detailed list of the steps in your experiment.

results…what did you observe when you performed the experiment?

conclusion…From what you observed, how would you answer your original question?

the title of my project is dancing raisins
btw i’m 10 years old

here is a link to my project
