Science Experiments

An electronic stopwatch gives a higher accuracy than a mechanical stop watch.

You have to have the science part because whats a science project without the science part.

A scientific key is a science process which is used to conclude a science problem question

The top number is called the numerator.

Because he proved it was wrong. (women can't be scientist dummy)

You are a scientist and you are trying to prove through the Scientific Method why there aren't any football players who played college ball at Duke in the National Football League. Your hypothesis is that players from schools that start with D can't make it into the NFL. After you find there's a guy playing for the Tennessee Titans who played at Dartmouth, you've proven your initial hypothesis wrong, so you change it: Players from North Carolina schools can't make it into the NFL. There's a bunch of guys playing in the NFL who were NC State players, which also negates your third hypothesis about Atlantic Coast Conference players not getting into the NFL. I have faith that eventually you'll come to the correct hypothesis--that Duke players don't get into the NFL because Duke's football team sucks.

why is it important to identify errors in an experiment

scientists use their data to make charts and ____ to communicate the results of an experiment.

Prediction, Method, Practical, Conclusion

Yes, i am as brilliant as you think i am!!!

because your adopted. nawh just kidding, but seriously one reason why a controlled experiment may not be possible is because...ok lets say you had an experiment of a cancer-causing chemical, they might exclude volunteers who have other serious health problems. by exerting great care in planning these kinds of investigations, scientists can discover reliable patters that add to scientific knowledge.

a petri dish is used to study small things

Operational definition

Scientists often re-do experiments to exclude the chance of an ERROR.

observation

It shows that the experiment is designed properly.

The liquid curve is called a meniscus.

the control was the open jar with meat

The current atomic model is called the electron cloud model because it describes electrons not as particles located at specific positions, but as existing within a cloud-like region around the nucleus, where they are most likely to be found. This model acknowledges the dual wave-particle nature of electrons and provides a more accurate representation of their behavior in an atom.
