Scientists use this instrument to measure the mass of an object.
What is a balance?
100
This variable is deliberately changed by the scientist during an experiment.
What is the independent variable?
100
A prediction or possible explanation that can be tested scientifically is called this.
What is a hypothesis?
100
This theory states that living things come from other living things.
What is biogenesis?

Measuring the height of seedlings gives you this type of numerical data.
What is quantitative data?

You should wear these when working with chemicals, heat, or glassware.
What are safety goggles?

A graduated cylinder is primarily used to measure this property of a liquid.
What is volume?
200
This variable is measured to determine the result of an experiment.
What is the dependent variable?
200
A motion-activated camera records the number of moose that pass through an area each day. Because the results are recorded as numbers, this is the type of data being collected.
What is quantitative data?
200
This scientist used meat and flies in an experiment that challenged spontaneous generation.
Who is Francesco Redi?

You know that birds have feathers. You see an unfamiliar animal with feathers and conclude that it must be a bird. This type of reasoning starts with a general rule and applies it to a specific situation.
What is deductive reasoning?
300
After completing a laboratory activity, you should always clean these with soap and water.
What are your hands?

When reading a graduated cylinder containing water, you read the measurement at this part of the curved surface.
What is the bottom of the meniscus?
300
On most graphs, the independent variable belongs on this axis.
What is the X-axis?
300
You notice that the strawberries in your garden all have tiny bite marks in them. You hypothesize that rabbits are the culprits, so you put a wire fence around half of the strawberry patch.In the strawberry experiment, scientists examine these to determine whether the fence made a difference.
What are bite marks on the strawberries?
300
In Redi's experiment, gauze allowed this to enter the jar while keeping flies out.
What is air?

You arrive home without the eggs you bought and decide that you probably left them at the cash register. This conclusion is an example of this.
What is an inference?
400
When unplugging electrical equipment, you should pull this instead of the cord.
What is the plug?

A rock causes the water level in a graduated cylinder to rise from 3.0 mL to 5.0 mL. This is the rock's volume.
What is 2.0 mL?
400
On the Temperature vs. Pressure graph on the test, this is the independent variable.
What is temperature?
400
Location of the garden, type of strawberry, and number of strawberries are examples of these variables that should remain the same.
What are controlled variables?
400
Your body begins shivering when you're cold to help maintain a stable internal environment. This demonstrates this characteristic of life.
What is maintaining an internal balance?
500
Scientists share their work so other scientists can examine procedures and conclusions for possible problems. This process is called this.
What is peer review?
500
TRUE or FALSE: If a chemical splashes on your skin, washing it for only 15 seconds is an appropriate lab-safety response.
What is FALSE?
500
Convert 16,793 grams to kilograms.
What is 16.793 kg?
500
According to the test graph, a gas has a pressure of 20 Pa at this temperature.
What is 40°C?
500
An experiment produces results that do NOT support your hypothesis. Explain why the experiment was still scientifically useful.
The experiment was not a waste because the results provide information that can be used to develop a new hypothesis and design another experiment.

The new house your parents are building is on a lot that contains a rare species of lizard. The individuals concerned about protecting this lizard would likely have what type of ethical worldview?
What is biocentric?
