. Four students are discussing how scientists conduct experiments. This is what they said:
Bill: “I think scientists just try different ideas until the data fits their hypothesis.”
Melissa: “I think scientists change their methods depending on their experiment.”
Molly: “I think there’s a set of steps that all scientists use called the scientific method.”
Robin: “I think scientists try different techniques but they all involve labs or experiments.”
Which student is correct?
Bill
Molly
Melissa
Robin
Which of these questions can be answered scientifically?
Which of these foods tastes best?
Which of these crops grows best in water?
How good is this piece of music?
How attractive is this flower?
Thomas and Karen are proud of their pet turtles. Each student thinks his/her turtle can win a race by riding in a toy car along a smooth track. Thomas thinks his turtle will go faster because it is bigger and stronger. Karen thinks her turtle will go faster because it is smaller. To find out which turtle will go faster, the students designed the following experiment:
Each turtle is placed in an identical toy car.
They both begin the race at a starting line and travel along the straight, flat track to a finish line 2 meters away.
They are pushed by a large fan placed behind the starting line.
The fan gives each car and turtle the exact amount of push at exactly the same time.
Thomas’s pet turtle is bigger. His turtle-car has a mass of 259g.
Karen’s turtle is smaller. Her turtle car has a mass of 178g.
Classmates, Jamie and Maria sit at the finish line with a stopwatch to report the number of seconds it takes each turtle-car to reach the finish line.
They repeat the race three times and write the resulting times in a data table
What question is this experiment designed to answer?
If the distance a turtle-car moves increases, what happens to the mass of the turtle?
If the amount of push each turtle-car receives increases, what happens to the distance it will travel?
If the mass of the turtle-car increases, what happens to the speed of the turtle car?
Which student is a better turtle-racer, Thomas or Karen?
