Biology S1 Final Review Part 1

What is the first step in the scientific method?

• Ask a question

• Hypothesis

• Conclusion

• Analyze data

A student wants to perform a science experiment about plants. He wants to know if a certain type of soil will make plants grow taller. Each pot will receive a different type of soil, but will get the same type of seed, water amount, and sunlight amount.What is the Independent Variable in this story?

• Amount of sunlight

• How tall the plant will grow

• Amount of water

• Type of material the plant is growing in

• Hypothesis

• Experimental Group

• Constants

If an animal shelter wants to see if a certain dog food causes a dog to gain weight, which of the following would NOT be a constant?

• Type of dog food given

• Amount of dog good given

• Time of day food is given

• Amount of exercise dog is given

Why is it important to have constants in an experiment?

• To make sure the experiment is fair

• Constants are not needed for experiments.

• To measure the dependent variables all at once

• To test many variables at a time

Which of the following is not an example of quantitative data?

• Temperature

• Speed

• Height

• Texture

Anna is in charge of studying how the amount of plant food (fertilizer) affects the height of a plant at a local garden. Which testable statement does she investigate?

• There is no way to test this hypothesis.

• If a plant receives two cups of food per day, then the height of the plant will increase

• If a plant gets different amounts of water and two cups of food per day, the height of the plant will increase

• If a plant receives more sunlight, the height of the plant will decrease

Why do many experiments include several trials instead of a single trial?

• Repetition of trials increases the accuracy of the results

• Repetition of trials decreases the sample size of the experiment.

• Repetition of trials makes data easier to analyze.

• It is not necessary to repeat trials

1. Aside from repeating a scientific experiment, what else must a scientist do to increase the accuracy of the results?

• Change the hypothesis

• Share data with other scientists for them to repeat or replicate

• Analyze the data faster

• Keep the data for themselves

Quantitative data can be

• seen

• measured

• manipulated

• heard
