The variable was tested during the "Swingers" investigation.
What is the length of the string?
100
A possible answer to your purpose/question based on your prior knowledge and research.
What is a hypothesis?
100
Something you notice with your 5-senses. A proven fact.
What is an observation?
100
The force of attraction between any two bodies in the universe.
What is gravity?
200
The measureable variable tested during the Lifeboats Investigation.
What is the size/height/capacity of the boat?
200
A set of objects working together to perform a function.
What is a system?
200
A conclusion drawn based on prior knowledge, experience and observations.
What is an inference?
200
This ecosystem is warm, humid, rainy and the home to a very diverse group of plants and animals.
What is the tripical rainforest?
300
Why did the way the pennies were placed in the boat matter during the Lifeboats Investigation?
Because the height that they were dropped from, and their placement in the boat (middle, side, etc.) caused the boat to rock and possibly tip over.
300
The variable that is changed in an experiment.
What is the independent variable?
300
The plants were 4 cm, 3 cm, and 5 cm tall on day 12. This is an example of a(n) _________.
Observation!
300
The changes in an organism to become more suited to its environment. (i.e. panda bears have flat molars to help them more easily chew and digest their food.)
What is an adaptation?
400
The 5 possible variables during the FOSS Plane Investigation.
What are the number of winds on the propeller, the size of the rubber band, the number of rubber bands, the number of passengers, and the incline of the flight line?
400
The variable that is affected by the change in your experiment.
What is the dependent variable?
400
The plants' soil was moist, so they must have had enough water to grow. This is an example of a(n) ______.
Inference!
400
The two properties of matter that govern the movement of the planets and all other bodies in the universe.
What is gravity and inertia?
500
What was the trust and drag during the FOSS Plane Investigation?
The winds of the rubber band were the thrust. The force of gravity and friction were the drag that caused the plane to stop, eventually.
500
An experiment where only one varible is tested.
What is a controlled experiment. The control group or test sets the standard for comparison when you analyze your data!
500
The plants were healthier when they were watered daily, instead of weekly. This is an example of a(n) ________.
Inference!
500
The force that tends to push an object outward when it rotates around a center.
