Vocabulary
The maximum volume of fluid that a container can hold
What is capacity?
The dependent variable in our lifeboat investigation.
What was the number of passengers?
Alexandra tested to see if type of music affects the height a plant grows.
Plant height is this type of variable
What is the dependent variable?
An experiment in which one, and only one variable is changed in order to assess its effect
What is a controlled experiment?
The independent variable in our lifeboat investigation
What was the capacity of each boat?
Alexandra tested to see if type of music affects the height a plant grows.
Plant type, amount of sunlight, amount of water, are all this type of variable.
What is the controlled variable?
The variable(s) held constant throughout an experiment
What are the controlled variables?
The controlled variables in our lifeboat investigation (name at least two)
What are the type of cup, the type of passenger (penny), the amount of water
Lili designed a controlled experiment to figure out the effect of boat design on the distance it would travel in 15 seconds. She changed the front end shape of the boat. (Drawing). She kept the capacity the same for every boat.
Name the dependent variable.
What is the distance the boat traveled in 15 seconds?
What is known/planned before an experiment starts
What is the independent variable?
The number of passengers in a lifeboat increases when we do this
What happens as we increase the capacity of a boat?
Lili designed a controlled experiment to figure out the effect of boat design on the distance it would travel in 15 seconds. She changed the front end shape of the boat. (Drawing). She kept the capacity the same for every boat.
Name the independent variable.
What is the shape of the front end of the boats?
What we find out by doing the experiment
What is the dependent variable?
What is the line of best fit?
Lili designed a controlled experiment to figure out the effect of boat design on the distance it would travel in 15 seconds. She changed the front end shape of the boat. (Drawing). She kept the capacity the same for every boat.
Name at least two controlled variables.
What are the
-capacity of the boat
-amount of time (15 seconds)
-starting position
-amount of water
-force pushing the boat.
