Scientific Inquiry and Skills

Light the Bunsen burner

Read all the instructions carefully

Mix the chemicals to see what happens

Clean your safety goggles

The radius

The meniscus

The cylinder line

The bubble

To keep liquids cool

To heat liquids so that the solvent evaporates, leaving a solid behind

To measure the volume of a gas

To store chemicals for long periods of time

It helps them reach the equipment better

It allows them to move away quickly if a spill or accident occurs

It prevents them from getting tired during the lab

The teacher can see them more easily

To prevent tripping hazards and keep the area safe

To make sure there is enough room to sit down

To help the teacher see who is working and who is not

To protect your belongings from getting dusty

An experiment where everything is kept the same except one independent variable

An experiment where every student in the group gets a turn to lead

An experiment that produces the result the student wanted

An experiment that is performed outside the laboratory

A large beaker

A volumetric pipette

An evaporating dish

A test tube

It can catch fire easily

It is poisonous if swallowed

It can chemically destroy or irreversibly damage metals and living tissue

It can explode if dropped

Only state if the hypothesis was right or wrong

Summarize the data and explain it using scientific theory

List all the errors they made during the method

Draw a new diagram of the equipment

Test tube holder

Test tube rack

Retort stand and clamp

Burette clamp

To understand how the natural world works through evidence

To prove that all old ideas were wrong

To create as many new chemicals as possible

To make sure everyone agrees with the scientist

The dog is brown and white

The dog weighs $25\text{ kg}$

The dog has soft fur

The dog seems happy

To throw away the data that is wrong

To look at the data carefully to find meaning or patterns

To change the data to match your hypothesis

To write the data in a secret code

To explain the results of the experiment

To list all the tools and substances needed to perform the experiment

To describe the scientist's feelings about the topic

To show the graph of the data

The test scores

The difficulty of the test

The number of hours of sleep

The age of the students

The experiment is very expensive.

The results are consistent and can be repeated by others.

The experiment only has one variable.

The scientist is famous.

Drawing a conclusion

Analyzing data

Making an observation or asking a question

Testing a hypothesis

The liquid turned from blue to yellow.

The temperature rose by $5.0^\circ C$.

The reaction took $34.2$ seconds.

The plant grew $12.0 mm$.

To make the experiment finish faster.

To control a variable that might affect the force reading on the spring scale.

Because friction only exists when objects move at constant speeds.

To make the data easier to graph.

Yes, once a hypothesis is supported, it becomes a scientific law.

No, in science, hypotheses are 'supported' or 'not supported', but never 'proven' with absolute certainty.

Yes, but only if the experiment was repeated at least three times.

No, because the hypothesis was just an opinion.

So the experiment is finished faster

To know exactly which change caused the result

To make the experiment more difficult

To use less equipment

How close a measurement is to the true value

How consistent or close measurements are to each other

The ability to guess the right answer

The use of very expensive equipment

Erase it immediately so it doesn't ruin the average

Note it down, repeat the trial, and investigate the cause

Force the other results to be similar to the anomaly

Assume the anomaly is the only correct result

The student calculated the mean incorrectly.

There was a constant force, like friction, that was not accounted for.

The experiment was not a fair test because the mass was too heavy.

Gravity does not work the same way in a classroom as in a lab.

To show where the student made mistakes.

To show the range or variability of the data points for each category.

To make the graph look more complicated and professional.

To indicate the predicted values for the next experiment.

The data will be accurate because the top of the meniscus is easier to see.

The data will be consistently higher than the true value.

The data will be consistently lower than the true value.

The reading will be correct because water curves upwards.
