Metrics, Measuring, & Science Inquiry Review Carla Cothern 8th Grade Science Maize South Middle School
Identify the independent & dependent variables in the following experiment. Joel wanted to test which type of ball could be hit farthest with a baseball bat. He tried hitting a tennis ball, baseball, basketball, golf ball, and a soccer ball. He used the same bat to test them all on the same day. He hit each one five times and measured the distance they traveled. IV: Types of Balls DV: Distance traveled
What branch of science includes the study of forces and molecules? Physical science
This is a possible explanation for an observation that can be tested. Hypothesis
What do you call the factors in an experiment that remain the same? Constants
What is the most accurate piece of equipment for measuring liquid volume --– a beaker, graduated cylinder, balance, or ruler? Graduated Cylinder
Comparing what you already know with the information you’re being given in order to decide whether or not you agree with it.What are you practicing? Critical Thinking
I notice there’s a beeping noise coming from the other room, so I think the alarm clock is going off in the other room. I made a logical explanation of something I observed based on past experiences – this is a…? Inference
How do you measure the volume of an object that has an irregular shape (like a pushpin)? Water Displacement – Add enough water to a graduated cylinder to cover the object. Read amount. Slide in. Read amount. Subtract.
Express 44,000 in scientific notation. 4.4 x 104
If the picture is a Celsius thermometer, what is the temperature? 76 degrees Celsius
This is the use of scientific knowledge to make products or tools that people can use. Technology
This is referred to as the act of using your senses to gather information to see what occurs. Observation
The official mass of a baseball for a Cubs game is 148.8 grams. When you measured its mass, you determined the mass to be 146.2 grams. What is your percent error? 1.75%
What is the volume of the block pictured (assume the measurements are in centimeters)? 125 cubic centimeters
What is an explanation of observations of events based on knowledge gained from many observations and investigations? Scientific Theory
What do you call the amount of space an object takes up? Volume
What type of data uses words to describe what is observed? Qualitative
Which factor in an experiment is manipulated or changed by the investigator? Independent Variable
In a controlled experiment, which group receives the factor being tested (the independent variable)? What is the other group called? Experimental Group Control Group
This is a statement about what will happen next in a sequence of events. Prediction
What is the factor measured or observed during an experiment? Dependent Variable
373.35 grams What is the mass of the object being measured with this device?
What term refers to a rule that describes a repeatable pattern or an event in nature that is always true? Scientific Law
What type of data uses numbers to describe what is observed? Quantitative
This is a logical explanation of an observation that is drawn from prior knowledge and experience. Inference
Write a hypothesis and identify the constants for the following experiment. Joel wanted to test which type of ball could be hit farthest with a baseball bat. He tried hitting a tennis ball, baseball, basketball, golf ball, and a soccer ball. He used the same bat to test them all on the same day. He hit each one five times and measured the distance they traveled. Sample Hypothesis: The tennis ball will travel further than the baseball, basketball, golf ball, and soccer ball when hit with a baseball bat. Constants: Bat, number of hits, environment (same day)
This is the factor in an experiment that stays the same. Constant
