We need to take the statement "Water is the universal solvent" with a grain of salt (pun intended). Of course it cannot dissolve everything, but it does dissolve more substances than any other liquid, so the term fits pretty well. Water's solvent properties affect all life on Earth, so water is ...

A common hypothesis states that hot water will dissolve more solute than cold water. Use this experiment to determine if temperature has any effect on solubility. Add a 1/2 cup of lukewarm tap water to a plastic cup. Weigh about 5 tablespoons of salt and gradually add the salt to the tap water, stirring to mix.
The water or milk in your cup is the solvent, and the powder that you pour into the cup is the solute. Briefly, a solute is something that gets dissolved. A solvent, on the other hand, is the substance in which the solute is dissolved.
Solubility experiments in chemistry are learning labs for most middle schoolers. Solubility means a solvent, often water, has the ability to dissolve another substance called a solute, such as sugar for instance.
Do you know which solids dissolve in water and which do not? The is a super fun kitchen chemistry science experiment for kids that's totally easy to set up! Learn about solutions, solutes, and solvents through experimenting with water and common kitchen ingredients. Grab the free printable for simple science experiments and STEM all year round!
EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water).
This is a fun experiment for preschoolers to predict and observe what dissolves in water. You’ll both have fun making predictions! I’ve mentioned before that Henry’s really been into experiments lately. He’s created his own experiments as well as begs for others to do quite often. Like I ...
