This is what the word "science" comes from

What is the Latin word for "to know"
100

The factor thatâ€™s being investigated or changed (tested); the only variable you change

What is the independent variable

100

Define hypothesis

A hypothesis is an educated guess, or a guess you make based on information you already know

100

True or false: metric length is measured using a standard ruler

False--we use a meter stick

100

This is what SI unit stands for

International system of equations

200

These are the 3 main branches of science

What are earth science, life science, physical science
200

the factor that you observe and measure to obtain your results; depends on other factors

What is the dependent variable

200
Explain why observations are important

helps you to gather information before an experiment, helps you come up with a hypothesis

200

Explain why using the SI units or metric system is important

The metric system is the internationally accepted system of measuring. It helps with eliminating confusion between measurements and helps with communicating scientific results

200

This is the SI (metric) unit for length

What is a meter

300

This is the definition for physical science

What is the study of matter and energy

300

These are the variables that all stay the same in the experiment

What are control variables

300

How might you communicate your results in an experiment

modeling the results, creating a graph, writing a scientific article

300

Convert 3.1 meters into dekameters

0.31 dam

300

This is the amount of space an object takes up, and its SI unit

What is volume (liter)

400
Explain the differences between science theory and law (at least 2)

Theory:

-an explanation of observations that is based on knowledge gained from many observations and investigations

-can be wrong and may be changed after additional tests or observations

Law:

-a rule that describes a repeatable pattern in science

-Does not explain how something happens, only states that it will happen

400

What are the 3 variables used:

Questions--Which type of fertilizer increases flower growth best?

Hypothesis--Fertilizer A in soil will increase flower growth most.

Independent: type of fertilizer

Dependent: flower growth

Control: water, sunlight, pot, type of flower, etc

400

Write a hypothesis to the following scenario:

Imagine you are conducting an experiment to investigate the effect of different sizes of seeds on plant growth; what would be your hypothesis?

The bigger seeds will produce the most amount of plant growth

400

Convert 0.00623 centimeters into kilometers

0.0000000623 kilometers

400

This is the amount of matter in an object, and its SI unit

What is mass (gram)

500

Explain why tools for taking accurate measurements are essential to the scientists' work

teacher check answer

500

What are the 3 variables used:

Question--

Which brand of popcorn leaves the least amount of un-popped kernels?

Hypothesis--Orville Redenbacherâ€™s Movie Theatre popcorn will leave the least amount of un-popped kernels.

Independent: popcorn brand

Dependent: amount of unpopped  kernels

Control: cooking time, microwave, bag placement, number of kernels to start with, etc.

500

These are the 8 steps of the scientific method (6 required for full points)

What are: ask questions, make observations, make a hypothesis, make predictions, test hypothesis, analyze results, draw conclusions, communicate results

500

500

This is the amount of mass in an objects given volume

What is density (mass / volume)
