It tells us how many times they measure the pencil's length.

It involves how close they come to identifying the correct length of the pencil.

It measures how many decimal places their ruler has.

Aiden, Lily, and David are conducting a science experiment. They want to know which of the following describes the accuracy of their measurements?

It involves how close they come to identifying the correct result.

It involves how consistently they can measure a result with the same method.

It tells us how many times they make a measurement.

It measures how many decimal places their equipment has.

Liam, Michael, and Abigail are working on a science project. They are discussing how they can improve the accuracy of their measurements. Which of the following suggestions would help them improve accuracy?

Using correctly calibrated equipment.

Using more finely incremented tools.

Following more detailed procedures.

Which axis do we plot the independent variable (IV) on?

It depends on the type of data used.

On which axis do we plot the dependent variable (DV)?

It depends on the type of data used.

Avery, Scarlett, and Aria are conducting a science experiment in their school. They are asked to graph the time taken for different types of seeds (sunflower, pumpkin, and tomato) to germinate. Which of the following is the correct way to present their data?

Seed types on x-axis, column graph.

Seed types on x-axis, scatter graph.

Time taken on x-axis, column graph.

Time taken on y-axis, scatter graph.

Luna, Aiden, and Charlotte are conducting a science experiment for their school project. They are trying to understand the germination process of sunflower seeds. They keep the seeds at different temperatures and record the time taken for them to germinate. If they were asked to graph their findings, which of the following is correct?

Temperature on x-axis, scatter graph.

Temperature on y-axis, scatter graph.

Time taken on x-axis, column graph.

Time taken on y-axis, column graph.

Charlotte, Aria, and Sophia are discussing their science project. They are confused about how a scientific theory is different from a hypothesis. Can you help them understand?

A scientific theory is an explanation based on many observations using repeated experiments, like the theory of gravity based on numerous observations and experiments, whereas a hypothesis is an educated guess that may or may not have been tested, like guessing the outcome of their science project.

A scientific theory is an educated guess that may or may not have been tested, like guessing the outcome of their science project, whereas a hypothesis is a prediction based on no research.

A scientific theory is the oldest original prediction on the topic.

A scientific theory can never be rejected, like the theory of relativity which is universally accepted.

During a physics experiment, Ethan, Aria, and James are trying to measure the weight of a ball using a digital scale. Which of the following describes the accuracy of their measurement?

It involves how close they come to identifying the correct weight of the ball.

It tells us how many times they measure the ball's weight.

It involves how consistently they can measure the ball's weight with the same method.

It measures how many decimal places their scale has.
