A possible hypothesis could be: "If salt is mixed with water and the solution is frozen, then the salt will not separate from the water, as both salt and water will freeze together into a solid."
When a mixture of salt and water freeze, the two substances will not separate. The mixture will just become frozen salt water.
A good hypothesis could be: "I hypothesize that soap will dissolve in water because the hydrophilic (water-attracting) part of the soap molecule will interact with the water molecules, leading to the breakdown of the soap into its components."
This only applies to whole blood intended for immediate transfusion without processing and freezing. After centrifuging to separate the components and freezing them individually various components can be kept good for periods as little as a few months to as long as several years.
A good hypothesis for a dry ice bubble experiment could be: "If dry ice is placed in warm water with soap, then bubbles will form due to the release of carbon dioxide gas from the dry ice interacting with the soap molecules."
Oh, dude, that's a good one! So, technically, soap lowers the freezing point of water, making it freeze at a lower temperature than regular water. But like, don't get too excited about having soap popsicles in your freezer. The difference is super tiny, so you won't be seeing any soap ice sculptures anytime soon.

A good hypothesis for glow in the dark water could be: "If a luminescent material is added to water, then the water will glow in the dark due to the light emitted by the luminescent material when exposed to darkness."
Type your answer here... It must have the if and then. It can not be a statement
A good hypothesis for making water glow could be that adding a phosphorescent or fluorescent material (such as certain chemicals or minerals) to the water may cause it to emit light when exposed to certain stimuli, such as UV light. Testing this hypothesis would involve experimenting with different materials and light sources to observe the glowing effect.
A good hypothesis could be: "I hypothesize that soap will dissolve in water because the hydrophilic (water-attracting) part of the soap molecule will interact with the water molecules, leading to the breakdown of the soap into its components."
Adding a salt the freezing point of water decrease.
At higher temperatures evaporation is faster.
A good science fair title for evaporation is- Vanishing Vapors: Evaporation
A correct or good hypothesis includes if then and because. A hypothesis must be a possible answer and must be testable
Experimentation is a good way to test a hypothesis.
