Metrics, meters, and Measures, OH MY! Methods are so scientific Hip HypothesesVery Variables
The metric base unit for length
What is meters?
What is 62.4 g?
What is 6.6 ml?
The number of cm in 2 m
What is 200 cm?
The correct order from smallest to largest for: millimeter Hectometer Decimeter centimeter Kilometer
What is: Millimeter, centimeter, decimeter, hectometer, kilometer?
An educated guess or prediction
What is a hypothesis?
The first step to the scientific method after an initial observation.
What is ask a question/define a problem?
A scientist does this to test their hypothesis
What is an experiment?
Why is it important to have a control group in an experiment? A. So you can make sure your results match your prediction B. So you have something to compare the variable to C. To make the experiment easier and faster to do.
What is b?
What to you do if your hypothesis is NOT SUPPORTED? A. Change your results to make it correct B. Start all over with a new problem C. Change your hypothesis and repeat the experiment.
What is C?
What you must do before you can write a hypothesis
What is define the problem/question and/or research the topic?
The 3 things a written hypothesis must have.
What is If…then…because?
The best hypothesis for an experiment on "What foods birds like to eat" A. Birds eat early in the morning B. Bird seed is the best food for birds C. Birds will choose to eat insects over bird seed because insects have more protein.
What is C?
The responding variable in the hypothesis: If a gerbil is fed 10 grams of food, then it will grow 3 grams bigger a week because it is consuming more calories than it expends.
What is the gerbils weight
The manipulated variable in the hypothesis: If I add 5 grams of minerals to my experimental plant, then the petals will be brighter than the control plant.
What is 5 grams of minerals
The MANIPULATED VARIABLE in an experiment on "Which apples will float better" A. The types of apple B. The size and shape of the containers of water C. How deep the water is.
What is A?
A CONTROLLED VARIABLE in an experiment on Which apples will float better" A. The types of apple B. The size and shape of the containers of water C. The color of apple
What is B?
The RESPONDING VARIABLE in an experiment on "Mentos causing diet coke to shoot out of the bottle" A. The type of coke bottle B. The different ingredients found in the diet coke and mentos. C. How high the diet coke went
What is C?
The CONTROL group in an experiment on "How well sun screens keep you from burning" A. Using no sunscreen B. testing 3 different sunscreens C. How much you burned while out in the sun.
What is A
What would be the MANIPULATED VARIABLE in an experiment on "Mentos causing diet coke or regular coke to shoot out of the bottle" A. The type of coke B. The type of bottle. C. How high the diet coke went
