No. False. Chemicals should be disposed of in a safe manner. Usually directions for disposal can be found on the box/tube/packet that the chemical came in. If none can be found, ask a professional (teacher, lab assistant, poison control expert) what is the proper disposal for a certain chemical. Excess materials poured down the drain may be poisonous to the environment or people, and can leak from the sewage system to our ground water and eventually to our food.

Can any excess materials that are not used during a laboratory experiment may be poured down the drain?
Most of the substances used in most laboratory experiments can be safely poured down a drain. However, laboratory experiments sometimes involve corrosive substances which would damage the plumbing if poured down the drain; they can also involve chemicals which, if they were to be mixed together as they are poured into the same drain, would undergo chemical reactions that might cause an explosion or a fire. And it is also possible that you are conducting experiments on highly toxic materials that would become an environmental hazard if poured down the drain. So not everything goes down the drain. You have to understand the nature of the substances that you are dealing with. Some thing go to a hazardous waste center instead, or can be neutralized in your own laboratory before you dispose of them.
What part of a scientific experiment is the hypothesis?
The hypothesis is a personal explanation of what youbelieve will happen during an experiment before you proceed in doing that experiment.
What are the variables for milk making plastic?
The independent variable in milk making plastic experiment is vinegar. The dependent variable is the milk and the controlled variables are the materials used for comparison that all remained same during the experiment. e.g. bowl , water etc.

If someone is using a balance during a laboratory experiment what are they measuring?
Measuring how heavy an object is compared to another object.
Mike is doing a laboratory experiment The experiment's materials list says that Mike needs to have a balance What will Mike most likely need to do during the experiment?
He most likely Mike will have to measure or compare the masses of some objects. MIKE HAS HUGE OBJECTS THAT HE MEASURES EVERY NIGHT . HE HAS MEASUREMENTS IN YOUR MOMMYS MOUTH AND HE PUTS IT IN TO SEE HOW DEEP IT WILL GO..THATS HOW MIKE MEASURES HIS OBJECTS
Why you should keep oneself clean during a food laboratory activity?
You need to keep clean during a food laboratory activity because you can contaminate the experiment and skew the results. This is the main reason although you may just like to be clean.
What is the meaning of Laboratory apparatuses?
The devices used in the laboratory during the experiments held and during the chemical combination of different elements are known as "laboratory apparatuses"

Why does changing materials effect your results during an experiment?
Blowing up a balloon with a helium tank, then blowing up a different balloon with your mouth will make a difference in the outcome of your experiment. It'll most likely give you more sources of error.
