One risk of the experiment is that the egg may crack or break during the process of adding it to the salt water. Another risk is that the salt water solution may not be mixed properly, leading to inaccurate results. Additionally, handling raw eggs can pose a risk of exposure to Salmonella or other foodborne pathogens if proper hygiene practices are not followed.
It is to make sure that carbon dioxide is present or not present in the experiment.
WikiAnswers is not going to do your experiment for you - that's cheating and it's wrong. Plus, you could be expelled for cheating. This is an easy enough experiment to do - just make a hypothesis of which one you think will dissolve the fastest and take 10 minutes to actually try it with hot and cold water. That's about how long it will take you to do the experiment yourself.
This is a cool experiment for my fourth grader but she also needs to understand why the liquid glows.
An example of a solution is a homogeneous mixture where a solute is dissolved in a solvent, such as salt dissolved in water. Solutions are commonly formed when substances mix at the molecular level, producing a uniform composition throughout.
To make snow on dust, you can use a fine water mist to dampen the dust particles. As the water freezes, it will create a snowy effect on the dust. This can be a fun experiment to simulate snowfall in a controlled environment.
IF the water has been purified, very few risks. Drinking directly from the spring, the water may contain organisms (bacteria, parasites, etc.) that can make you sick.

Make DNA cells or molocules. Make the brain. Make animals and their habitats. Make the water cycle.
The independent variable is the thing that changes with in the experiment to make it an experiment. For example, say I was doing an experiment on something such as "Which sponge brand can absorb the most water?" The independent variable would be the different sponge brands because it would be the thing that changes with in the experiment. Otherwise, if you didn't make an independent variable (the different sponge brands in this case) it wouldn't be an experiment because a sponge of the same brand should hold about the same amount of water as the others.
It would make an excellent experiment. However, most sugars will dissolve best in hot water.
If you did the experiment wrong
Chloroform water can be prepared by dissolving chloroform in water. Due to the potential health risks associated with chloroform, it is not recommended to make or use chloroform water outside of controlled laboratory settings.
Fist the scientist figures out the aim of their experiment. Then they make a prediction. And then they make a theory before actually doing their experiment. After the experiment they make a conclusion and then evaluate their experiment (what went wrong, how things could be better...). Hope this helped! :)
Make before an experiment; but avoid excess salt, you don't need salt water in the mouth.
This depends on the specific experiment desired.
You use a formula to make an experiment.
