Prescription glasses generally do not provide sufficient eye protection, particularly on the sides. There are several styles of laboratory eye protection that are designed to fit over prescription glasses; you should wear the prescription glasses and safety glasses or safety goggles as well. It's also possible to buy prescription safety glasses, but they're fairly expensive. Again: Ordinary prescription glasses are not a substitute for safety glasses/goggles.
Because If they don't, the scientists won't know what the difference is in.Example:You have two glasses of water. One is labeled control.The other is labeled salt. The one labeled controlhas nothing added to it. The one labeled salt has salt added to it. Is there a difference between the two glasses?If an experiment has a control in it, that means the scientist needs to know if there is a difference in the experiment.
An experiment is when you find an answer to a question that you asked. You need some materals and steps that you have to follow. For example, maybe you asked,"How do you make an egg float in water?" The answer is simple.First gather these materials-2 eggsTwo clear drinking glassesSaltA tablespoonSteps-Fill two drinking glasses with the same amount of water.Next put 8 tablespoons of salt in one of the glasses, not both.Put one of the egg in salt water and one egg in fresh water.Now one egg floats and one doesn't!An experiment can be really fun.You get to have fun and know the answers to your science questions.Sometimes you can even make up your own experiments at home if you want to or if you don't have an computer or a science experiment book.You can even do your experiment now if you likeHave Fun!!!!
No units of measure other than 'glasses specified....8 glasses = 8 glasses
1 liter is equal to 4 glassess 2 liter is equal to 8 glasses 0.5 liters is equal to 2.5 glasses Therefore 2.5 glasses is equal to 8+2.5=10.5 glasses or 10 and a half glasses.

Churchill was known to wear a small brown pair of circular reading glasses, but did not wear them on a daily basis.
Depending on the experiment, the shape of the glass, its thickness, the amount of liquid in it.
Wear a protect suit, eye glasses, glove.

3D movie glasses can be obtained in wholesale quantities from DHGate. Note that 3D movie theaters use circular polarization to produce the 3D effect, which is totally different from the shutter systems domestic 3D TVs use. Movie theater 3D glasses will not work with a 3D TV - neither will the make effective or safe sunglasses.

Wal-Mart, K-Mart, and most other general retailers will carry inexpensive reading glasses. The price usually will indicate the comparative quality. Prescription glasses are recommended where vision differs in the left and right eye.
