Multiple Choice

What makes a hypothesis a VALID statement?

• It needs to be a testable and logical statement.

• It needs to be highly opinionated.

• It should be worded to persuade an audience.

• It should be done before research.

Multiple Choice

How can scientists analyze data?

• By lying about results that do not support their data.

• By creating a new experiment for new data.

• By stating if their hypothesis was true or false.

• By creating graphs and making logical explanations about their data.

Multiple Choice

Why is completing research an important part of the scientific method?

• It allows the scientists to get final data before the experiment is done.

• It allows the scientist to understand the topic better and make a logical hypothesis.

• It allows the audience to understand why the experiment did not work.

• None of the above.

Multiple Choice

An observation is different from an inference since:

• Inferences always lead to experiments, observations do not

• Observations do not temporarily explain something like inferences do

• You make thousands of observations daily, but less inferences

• Inferences can be proven, observations cannot be

Multiple Choice

The definition of an inference is:

• A testable statement made on prior knowledge that leads to experimentation

• Accurate and firm explanations of how the world around you works and why

• Made with your senses to help learn about the world around you

• An untested and temporary explanation of multiple similar observations.

Multiple Choice

What type of data would you need for a bar graph?

• Categorial Data/Comparison Data

• Data over time

• Percentages

• Qualitative or descriptive data

Multiple Choice

What type of data would you use with a line graph?

• Categorical/Comparison Data

• Data over a specific time frame

• Percentages

• None of the above

​Topic:

Marine Science Technology & History of Marine Science

Multiple Choice

Why is it important to continue to learn and explore about the ocean?

• Over 90% of the ocean has been discovered. We still need to discover the other 10%.

• Only 5% of the ocean has actually been discovered. The ocean also provides us a variety of resources.

• Only 20% of the ocean has been discovered. The ocean provides lots of jobs.

• None of the above.

Multiple Choice

What does SCUBA stands for?

• Self Controlled Underwater Breaking Apparatus

• Self Controlled Underwater Breathing Apparatus

• Self Contained Underwater Breaking Apparatus

• Self Contained Underwater Breathing Apparatus

Multiple Choice

What does AUV stand for?

• Autonomous Underwater Vehicle

• Autonomous Above-Water Vehicle

• Autoparts Underwater Vehicle

• Automatic Underwater Vessicle

Multiple Choice

ROV stands for

• remotely operated vehicle

• remotely operated vesicle

• road operated vehicle

• remotely operation vehicle

Multiple Choice

Who was Charles Darwin and how was he important to marine science?

• Designed the first wooden sailing ship.

• Created the first compass.

• Mapped the ocean floors and discovered a lot of marine species.

• This famous scientist was the founding father of evolution that wrote the origin of species

Multiple Choice

Who was Edward Forbes and how was important to marine science?

• This famous scientist mapped the seafloor, called the father of Oceanography

• Designed the first compass

• Designed the first wooden sailing ship to voyage across hte ocean.

• None of the above.

• Compasses, wooden ships, star navigation

• Snorkeling and Compasses

Multiple Choice

What are some of the benefits that technology has in the field of Marine Science?

• It allows scientists to work from home.

• It allows scientists to do other tasks while researching.

• All the above.

​Topic: Properties of Water

​List the Properties of Water

• ​Universal Solvent -- easily dissolves other compounds

• ​High Surface Tension -- creates skin-like layer on the surface from cohesive forces

• ​Expansion Upon Freezing -- Water molecules expand when they freeze and ice becomes less dense than water

• ​High Specific Heat -- Takes a lot of energy to heat up

• ​Cohesive -- Water Molecules stick to each other

• ​Adhesive -- Water molecules stick to other surfaces

Multiple Choice

What type of bond is formed between the oxygen and hydrogen that makeup water?

• hydrogen bond

• covalent bond

• ionic bond

• negative bond

Multiple Choice

What type of bond is formed between 2 water molecules?

• Covalent Bond

• Hydrogen Bond

• Ionic Bond

• Negative Bond

​Draw the pH scale and LABEL IT accurately!

​Draw a diagram of a solvent, solute, and solution.

Multiple Choice

What happens to water when it freezes?

• Water molecules EXPAND and become more dense.

• Water molecules SHRINK and become less dense.

• Water molecules EXPAND and become less dense.

• Water Molecules Shrink and more dense.

​Draw and Label a Water Molecule Diagram
