Paula Said:How level is this science fair project? Elementary, Middle, or High School?
We Answered:Well, it depends what you're going to do with it. Are you going to simply explain why it reacts the way it does? Are you going to make your own? Are you going to put it in something or put something on it to cause an interesting reaction?
In any case, it all depends on how you do it; it could be either a Middle or High School level project.
I just tried Googling "Instant Hot Ice Science Project", "Instant Hot Ice Experiment", and "Instant Hot Ice Reaction" and all I could find were ways to make your own. Maybe you should make your own. Or start searching for interesting things to do with it to cause chemical reactions or something.
Ruby Said:science fair projects ideas for middle school please?
We Answered:Opportunities for recapturing waste energy. There are very many things that people do that waste energy when it could be recaptured.
One example of a recent technology that does recapture energy is called regenerative braking. In older cars, when you apply the brake, all that kinetic energy of the car is lost as heat and noise. Newer, hybrid cars turn a generator when the brake is applied so the kinetic energy is transformed into electrical energy.
There are hundreds of similar "machines" that people use that could recapture energy. An elevator, for example, uses energy to raise people (or cargo) to a higher floor. By raising people to a higher level, these people now have higher potential energy. This higher potential energy could be recaptured when they ride the elevator back to the ground floor. This would be just like the brake in a hybrid car: instead of using a brake to slow the descent of the elevator car, a descending elevator could turn a generator and recapture some of the energy that was used to lift the occupants.
Water is pumped up to each floor of a large office building. That pumping uses energy, but when someone washes their hands or flushes the toilet, that water just falls (inside pipes) back to ground level (or even lower). Just like the water behind a damn, water falling from the fiftieth floor of an office building is full of potential energy, but right now, all that energy is lost.

Does the power of a microwave affect how well it makes popcorn?
Do all brands of diapers absorb the same amount of liquid? Does it matter what the liquid is (water as opposed to juice or... um.. urine)?
Do all dishwashing detergents produce the same amount of bubbles? Clean the same number of dishes?
Is the nutritional content of different brands of a vegetable (e.g., canned peas) the same?
How permanent are permanent markers? What solvents (e.g., water, alcohol, vinegar, detergent solution) will remove the ink? Do different brands/types of markers produce the same results?
Is laundry detergent as effective if you use less than the recommended amount? More?
Do all hairsprays hold equally well? Equally long? Does type of hair affect the results?
What effect do additives have on the crystals? You could add food coloring, flavorings, or other 'impurities'.
What steps can you take to maximize crystal size? You can affect vibration, humidity, temperature, rate of evaporation, purity of your growth medium, and time allowed for crystal growth.
How do different factors affect seed germination? Factors that you could test include the intensity, duration, or type of light, the temperature, the amount of water, the presence/absence of certain chemicals, or the presence/absence of soil. You can look at the percentage of seeds that germinate or the rate at which seeds germinate.
Is a seed affected by its size? Do different size seeds have different germination rates or percentages? Does seed size affect the growth rate or final size of a plant?
How does cold storage affect the germination of seeds? Factors you can control include the type of seeds, length of storage, temperature of storage, and other variables, such as light and humidity.
What conditions affect the ripening of fruit? Look at ethylene and enclosing a fruit in a sealed bag, temperature, light, or nearness to other pieces or fruit.
How are different soils affected by erosion? You can make your own wind or water and evaluate the effects on soil. If you have access to a very cold freezer, you can look at the effects of freeze and thaw cycles.
How does the pH of soil relate to the pH of the water around the soil? You can make your own pH paper, test the pH of the soil, add water, then test the pH of the water. Are the two values the same? If not, is there a relationship between them?
How close does a plant have to be to a pesticide for it to work? What factors influence the effectiveness of a pesticide (rain? light? wind?)? How much can you dilute a pesticide while retaining its effectiveness? How effective are natural pest deterrents?
