Analyzing Data

You want to make a graph for an experiment you did about plant growth over a two week period of time. What type of graph would you use?

• bar graph

• line graph

• pictograph

• pie chart

Liam, Mia, and Rohan conducted an experiment. What data does this graph represent?

• Change in temperature of a liquid over time in 3 different containers

• How temperature can change the molecules in a material

• The phase changes of a material

• What type of container people use the most to store hot liquids.

Answer explanation

The graph represents the change in temperature of a liquid over time in three different containers. This is evident as the correct answer aligns with this description. The other options, such as the phase changes of a material or the effect of temperature on molecules, are not directly related to the data represented in the graph.

Priya, Arjun, and Grace conducted an experiment with gummy bears. They submerged gummy bears in different liquids and observed the changes. Based on their observations, which of the following statements is accurate?

• There was no change to the gummy bear after 24 hours of being submerged in water.

• The gummy bear changed the most in length from being submerged in vinegar.

• The gummy bear that has the greatest mass is the one that was submerged in vinegar.

• Gummy bears change color when they are submerged in different liquids.

Answer explanation

The correct observation based on the graph is that the gummy bear changed the most in length after being submerged in vinegar. This implies that the vinegar had the most significant impact on the gummy bear's size compared to other liquids. The other options, such as no change after 24 hours in water, or color change, are not supported by the graph.

Imagine Michael, Harper, and Noah were conducting a fun experiment with gummy bears. Based on the data shown in the graph, can you guess what the controlled variable in their experiment was?

• the type of solution they used

• the length of the gummy bear before they submerged it

• the length of the gummy bear after they submerged it

Answer explanation

The controlled variable in this experiment is the length of the gummy bear before it was submerged. This is because the controlled variable is the one that remains constant throughout the experiment, allowing the effect of the independent variable (type of solution) on the dependent variable (length of the gummy bear after submersion) to be observed.

Ethan, Scarlett, and David are working on a science project. They are wondering why they should use graphs, charts, and tables. Can you help them understand the purpose of these tools?

• To help them visualize the results from their experiment.

• To make their project look nice.

• To practice what they learned in Math class.

• To practice their drawing skills.

Answer explanation

The purpose of graphs, charts, and tables is to help scientists visualize results from an experiment. These visual representations make it easier to understand and interpret data, identify trends, and communicate findings. The other options, such as making the experiment look nice or practicing math and drawing skills, are not the primary purposes of these tools.

Abigail, Emma, and Ava are having a debate about Earth's water. What information could you get from this graph to help them?

• how much water is on Earth

• the percentage of the earth that is covered in water

• how land is available on earth

• how tall the highest mountain is

Answer explanation

The question asks about the information that can be derived from a certain graph. The correct answer is 'the percentage of the earth that is covered in water'. This implies that the graph must be presenting data related to the distribution of water and land on Earth. Other options like 'how much water is on Earth', 'how land is available on earth', and 'how tall the highest mountain is' are not directly related to the information that the graph could provide.

Emma, Luna, and Arjun are having a debate about the number of people who visited a park in 1997. According to the graph they found, how many people visited the park that year?

• 60 visitors

• 60,000 visitors

• 6 million visitors

Answer explanation

The question asks for the number of people who visited the park in 1997. Among the given options, 60,000 visitors is the correct choice, as it represents the accurate number of visitors to the park in that year.

Noah, Anika, and Liam are having a debate about the best title for this graph. Can you help them decide?

• The effect of the number of trees on the type of tree

• The change in type of trees over number of trees

• Number of trees vs. Type of trees

• A comparison of the number of trees for 5 different types of trees

Answer explanation

The best title for the graph, as per the question, is 'A comparison of the number of trees for 5 different types of trees'. This title is most suitable as it indicates that the graph is comparing the number of trees across different types. The other options either suggest a cause-effect relationship or a change over time, which is not implied in the question.
