I need some ideas for high school science projects. It doesnt really matter what field of science, but i would prefer chemistry, biology, or physics. Really Urgent! Thanks!

What about a project on osmotic pressure. Put a salt solution inside a thistle tube, place a membrane over the top, invert it into a water solution that has coloring agent of some kind. The colored solution should go through the membrane and make the level of liquid inside the thistle tube move upward. I hope this helps get you started.

Because I'm homeschooled, I don't have access to alot of lab equipment so I can't really do this experiment(it's a great idea though), do you have any other ideas?

Thanks, I'll try these sites!

You're welcome! I'm glad you liked the osmotic pressure project idea, even though you can't do it at the moment. However, I understand that you have limited access to lab equipment, so here are a couple of websites that can provide you with project ideas for high school science:

1. http://www.energyquest.ca.gov/projects/index.html: This website provides a wide range of energy-related science fair project ideas. You can choose from various categories such as electricity, renewable energy, and energy efficiency. Each project has a brief description along with the materials required and step-by-step instructions on how to conduct the experiment.

2. http://www.all-science-fair-projects.com/: This website offers a vast collection of science fair project ideas across various fields such as chemistry, physics, biology, and more. You can browse through different categories or search for specific keywords to find projects that interest you. Each project includes details about the hypothesis, materials, procedure, and expected results.

Remember to choose a project that aligns with your interests and available resources. It's also important to consider the time and effort required to complete the project within your given deadline. I hope these websites help you find the perfect science project for your high school assignment! Good luck!
