Have you ever tried to prepare a meal using your own original recipe

• Yes

• No

What is the first step in the scientific method?

• Construct a Hypothesis

• Ask a Question

• Do Background Research

• Test with an Experiment

What is the most important characteristic of a scientific question?

• It must start with 'Why' or 'How'.

• It must be general enough to cover many topics.

• It must be testable through an experiment.

• It must be answerable by looking up a recipe.

What is a key benefit of conducting background research in the scientific method?

• It helps you skip the experiment phase.

• It allows you to find the best way to do things and understand what data to collect.

• It provides all the answers without needing further investigation.

• It is only necessary if you don't know anything about the topic.

What is a hypothesis in the context of the scientific method?

• A random guess about the experiment's outcome.

• A final conclusion drawn from the experiment.

• An educated guess based on background research that includes a testable prediction.

• A detailed procedure for conducting an experiment.

In the popping boba experiment, what are the dependent variables that are measured?

• Reaction temperature and ingredient concentrations

• Diameter and height of the boba

• Type of liquid used

• Acidity of the food mixture

What is the primary purpose of controlled variables in an experiment?

• To be changed by the experimenter to observe their effect.

• To be measured as the outcome of the experiment.

• To ensure that only the independent variable causes observed changes.

• To form the basis of the experimental hypothesis.

Why is it important to repeat an experiment for each testing condition multiple times?

• To make the experiment longer and more complex.

• To ensure the results are reproducible and not random.

• To use up all available materials.

• To confirm the initial hypothesis is always correct.

According to the scientific method, what should be done if an experimental procedure is not working as expected?

• Immediately conclude that the hypothesis is incorrect.

• Troubleshoot the procedure and restart the experiment.

• Change the independent variable without troubleshooting.

• Analyze the incomplete data and draw conclusions.

How do we analyze the data from an experiment?

• Analyze data by organizing, calculating , and representing and visualizing results.

• Make assumptions without that agree with our expectations

• Only focus on the good data

• Ignore everything that fails completely
