What is a control group in a science experiment?
A control group is the unaffected group in a science experiment.
How is science present in a backpack?
This is basically to do with how it has changed over time, from 20 years ago there were no health and safety regulations in place but this had to change because evidence was getting contaminated and people were getting away with all sorts of crimes including murder!! nowadays protective clothing must be worn by all crime scene investigators 'csi' to protect them from getting infected on broken needles for example and to prevent the likelyhood of contaminating evidence.
What happens if the experiment dose not confirm hypothesis?
This indicates that the hypothesis is probably incorrect and a new hypothesis needs to be developed. A negative result for a scientific experiment is just as important as a positive result and means that the experiment was a success.
What is the relationship between distance and time?
There is no direct relationship between distance and time. Two airplanes
can easily cover very different distances in the same amount of time.
There can be an indirect relationship, that depends on speed.
Why research improves the quality of life?
Research helps many people understand how things work. When you have more information about how things work, you can adjust how you live to ensure you are taking actions to benefit you.
What is an educated guess based on knowledge and observation?
In mathematics, it is often useful to make an educated guess when working on the solution to a problem. This is called an estimate.
How do scientists conduct science experiments?
scientists lead on what other people do on there project
Why must a science experiment have a control group?
A control group helps the scientist contrast between what normally happens and what happens when he/she does something to affect it.
For example, fruit flies living in tropical areas have the tropical ds2 allele, which is helpful in tropical areas. A scientist puts some of the flies into a place where there's less vegetation, and two of those migrated flies produce an offspring with a mutated ds2 gene that helps that mutated fly survive where there's less vegetation. In this whole experiment, the fruit flies with the tropical ds2 allele living in the tropical areas would be the control group, which is important because it helped the scientist contrast the survival of flies in different environments.
What is the system of measuring that most scientists use around the world?
cgs (centimetre,gram,seconds) or SI system i.e mks (metre, kilogram,seconds)
Information collected by counting can best be displayed on a?

How can I make a title of my science investigatory project?
There various ideas that you can use to make a title of your science investigatory project. You can come up with a title based on the content, the process or the end result expected.
