Can you please help me to chose for my science project?

Definitely "Why does water expand when it is frozen?" It sounds more scientific and general. You may also want to expermiment on different chemecals, and record their expansion rate.

Titrations are always cool.  The color changes offer a visual aspect.  Just make sure that you know what the titration is really measuring.\n\nThe key to a good science project is stating a good hypothesis and then explaining WHY you think the hypothesis is true.  Then design the experiment that will test the hypothesis.  Be sure to include a control so you know that you are measuring the right thing.  Then analyze the data and determine if they hypothesis was supported or not.  Besure to explain WHY or WHY NOT which ever the outcome is.

I would suggest the rock cycle. This is a basic earth science project that you can make as simple or complex as you want. You can identify the three major parts and how they interact going from one part of the cycle to another. You can identify the different properties of these rocks (and find samples if you want). If you want to make it really elaborate, you can bring in how plate tectonics drives the rock cycle, and how volcanism, metamorphism, and sedimentation form the Earth's surfaces.\n\nAnother topic that might be interesting to you would be to identify all the products and materials around you that come from rocks and minerals. Since this includes almost everything (e.g gypsum wallboard, clay in ceramics, iron in cars, aluminum in beverage containers and cars, plastic made from oil, shampoo made from oil, household detergent made from oil, electricity made from burning coal and natural gas, salt on your table, etc). You could look for the most surprising things, and could perhaps include how soil is made from weathered rock so even trees and plants come from rocks. You can do some research on how each of these materials is mined and where it comes from. You get the idea, right? \n\nDepending on where you live, you might do something on natural hazards in your area.If you have earthquakes you could find a fault map for your area and research earthquake hazards. If you have landslides or coastal erosion you could research what causes these things. Of course, if you live next to a volcano that is an excellent topic.  For example, see if you can find an eruption hazard map.  You might want to make sure your teacher approved of this because it might not be within the scope of your class (some teachers might consider this geography more than earth science). \n\nJust a bunch of ideas from a geologist. Hope this helps.

A classic, but great visual experiment is sucking a hard boiled egg into an erlenmyer flask. It is done by using the principles of the kinetic theory of matter.\nAnother cool project might be doing something with dry ice. Find a place that you can get dry ice and do fun stuff with it, like create smoke, put bubble solution in water and then drop in dry ice to make bubbles that, when you pop, let out white smoke.\n\nAnother idea might be to do some cool colorful reactions. Make some dye molecules or something.\n\nHope one of these ideas works for you.

I did a science fair project that combined science and economics - it was called "Which Dish Washing Liquid is Best for Your Buck".  I tested which dish washing liquid was the best by seeing how many drops of it were needed to destroy the surface tension of a glass of water.  I then figured out how much each drop of dish washing liquid cost, and reported on the best value.  The judges seemed to like the economics side of it as well as the science fair side of it.  Good Luck!
