A student wanted to study the amount of mold growing on pizza at different temperatures. In the experiment, the student set up four identical pans of pizza. Each pan contained the same amount of pizza. The temperatures and light conditions are shown in the data table below. One error made in setting up the experiment was that the four pans of pizza

received different amounts of light

Which conclusion about this species of bacteria is best supported by the information in the graphs?

Antibiotic C was most effective in controlling the growth.

Antibiotic A continuously slowed the growth.

Antibiotic B was least effective in controlling the growth.

Antibiotics A and B slowed the growth.

A good scientific conclusion includes

your opinion about how fun it was

One useful tool that may help a scientist recognize trends and analyze data is/are:

discussing raw data in a paragraph

Which SEP would this fall into?

Engaging in argument from evidence

Planning and carrying out investigations

Use mathematics and computational thinking

Which SEP does this image fit into?

Analyzing and interpreting data

Asking questions and defining problems

Engaging in argument from evidence

What is wrong with this graph?

Nothing is wrong with the graph.

When a science question asks you to 'construct an explanation' for a natural phenomenon, what is the most important thing your response must be based on?

Scientific evidence and reasoning.

Information from a single textbook.

What the majority of people believe.

When a science or engineering task asks you to 'evaluate' something (like a claim, evidence, or a design solution), what are you expected to do?

Judge its merit, validity, or effectiveness based on criteria and evidence.

Only find flaws or weaknesses within the system or solution using resources.

Just state whether you agree or disagree.

When you are asked to 'analyze and interpret data,' what are you primarily looking for?

Patterns, trends, and relationships within and between datasets.

Interesting colors or shapes in graphs.

Whether the data supports your initial idea.

Identifying patterns in observations or data is important in science because patterns can:

Guide organization, prompt questions, and be used as evidence.

Only be found in biological systems.

Prove a hypothesis without further testing.

Why is it important in science to consider the 'scale' at which a phenomenon is observed (e.g., looking at a single cell vs. a whole organism)?

The observed function or properties of a system can change with scale.

Different scales require different types of measurements (metric vs. imperial).

Scientists just like looking at different sizes.

It helps determine the cost of research.

When new evidence is available or feedback is received, scientists and engineers may need to 'revise' or 'refine' an explanation, model, or design solution. What does this process involve?

Modifying the explanation, model, or design based on the new information or feedback to improve its accuracy or effectiveness.

Making the explanation or design more complicated.

Throwing away the old explanation/design and starting over.

Ignoring the new information if it contradicts the original idea.

Which of the following best describes a dependent variable in an experiment?

The factor that is measured or observed as a result of changes in the experiment.

The factor that is kept the same throughout the experiment.

The factor that is intentionally changed by the scientist.

The equipment used to collect data.

What is the main purpose of using a control group in a scientific investigation?

To provide a standard for comparison with the experimental group.

To increase the number of variables being tested.

To ensure the experiment is more complicated.

Which of the following is an example of a qualitative observation?

The solution turned blue after mixing.

The length of the string is 15 centimeters.

The mass of the object is 10 grams.

The temperature increased by 5 degrees Celsius.

The analysis of data gathered during a particular experiment is necessary in order to

(4) draw a valid conclusion for that experiment

(1) formulate a hypothesis for that experiment

(2) develop a research plan for the experiment

(3) design a control for the experiment

A student conducted an original, well-designed experiment, carefully following proper scientific procedure. In order for the conclusions to become generally accepted, the experiment must

(2) be repeated to verify the reliability of the data

(1) contain several experimental variables

(3) support the original hypothesis

(4) be conducted by a scientist

In the 18th century, Carolus Linnaeus classified organism based on their structural similarities. Modern classification determines relationships more accurately because it is based on genetic and other biochemical similarities. This change in classification method best illustrations that

all scientific explanations are tentative and subject to change and improvement

multiple trials are required to increase the validity of a scientific explanation

scientific explanations are subject to the ethical view of the scientist proposing them

peer review is required to validate the results of scientific investigations

Why do we want to test one variable at a time?

To know what is causing the changes. This helps us understand cause and effect.

Because it is hard to setup a data table with more

It is what has always been done

Anita is studying the factors that affect seed growth. She wants to test whether soaking seeds in water affects the sprouting process. Which should Anita measure to get the most useful results

growth of 50 soaked seeds and 50 regular seeds at given temperature

growth of 100 soaked seeds at a given temperature

growth of 100 regular seeds at different temperatures

growth of 50 soaked seeds and 50 regular seeds at a different temperatures

When heating liquid materials in laboratory glassware, a student should always

record the temperature of the liquid

Which of the following is NOT a well written scientific question?

What is the gender of the buffalo leading the pack?

Why did the lions attack the baby buffalo?

Why are the female lions the ones hunting?

Does the pH of the rain have an affect on the growth rate of grasses?
