Michaela is conducting an experiment on the speed of toy cars on different surfaces. For each trial, she uses a ramp covered in different substance. Michaela uses a different type of toy car for each trial to make sure it is free from an materials from the previous trial. Michaela measures the distance traveled and time of each car. Which of the following is a change Michaela should make in her investigation in order to achieve more valid results?
https://tinyurl.com/k8n857h
She should measure the force each car exerts on each surface
She should measure the direction in which the cars are traveling
She should use the same material for each trial of her investigation
She should use the same type of car for each trial of her investigation
Prior to the 15th century, most people believed Earth was the center of the universe. In the late 1600's, the telescope came into use for astronomical observations. Explain the result of the telescope
https://tinyurl.com/t7akeew
Astronomers could gather more evidence about our solar system and so went from a geocentric to a heliocentric model
The invention of the telescope resulted in few changes to our theory that the solar system was geocentric
A scientist testing the effects of a new medicine that will treat anemia, a blood disorder, uses the sample size of 15 patients for a study. All of the patients are from the same large city, are of varying ages, and are male. Which of the following is an accurate statement regarding this investigation?
https://www.youtube.com/watch?v=_ZV5140OykE
Using a sample size of 15 people is too small. The investigation will not be reliable and valid test of the medicine
Using a sample of people of the same gender always allows scientists to obtain the most accurate data for the study
Using varying ages of people will add necessary data to this study causing the investigation's results to be informative and useful
Using a sample from the same city is necessary to allow the scientist to control for all other factors that may have an effect on the medicine's effectiveness
Tamika is conducting an investigation on the effect of different types of soil on the growth of Bermuda grass. Which of the following describes the methodology she should use in her investigation?
https://tinyurl.com/4soq36p
She should repeat her investigation several times for reliability of results
She should check the growth of her plants once a month and record her findings
She should keep each plant in a separate room so that they are not influenced by one another
She should provide each plant with enough fertilizer to keep it growing at the same rate as the other plants
Justin wants to make candy canes for his family. He knows that one step is to dissolve sugar in water so that he will get a syrup. Justin wants to know the most effective way to perform this step, so he is testing how temperature affects the rate at which sugar dissolves in water. What is a variable he needs to keep constant?
https://tinyurl.com/w7ahpfk
type of sugar
temperature
color of the candy
flavor of candy
Marcus is completing a science experiment for class. He wants to see what effect water temperature has on plants. If his experiment contains one independent variable, which of the following would NOT be a constant in his experiment?
https://tinyurl.com/zyheyl5
https://tinyurl.com/2d85ny7
The type of plant used
The water temperature
The room temperature
The pot used for the plants
Miranda performed an experiment to determine what makes an object sink or float in water. She experimented with 10 different items and recorded the results. Which of the following is correct?
https://phet.colorado.edu/en/simulation/legacy/density
The object's shape is the only determining factor
The size of the object determines if it will sink or float
The mass and volume of an object determine if it will sink or float
Light-colored objects tend to float more easily than darker-colored objects
When Julian compares his physics lab report to Kate's biology report, he realizes that they were different. Julian also notices that the same method of experiment was used in both labs. Why would Julian and Kate use the same method for different subjects?
https://phet.colorado.edu/en/simulations/category/physics
https://phet.colorado.edu/en/simulations/category/biology
Both subjects use common scientific principles
Biology and physics use the same types of intstruments
They have the same teacher who uses identical methods
They were doing a lab on the effect of light on an organism based on mass
Two students prepare lab reports, one for physics class and the other for a biology class. Which of the following items will both reports contain?
Mathematical equations
The results of an investigation
Measurements of energy levels
The scientific name of an organism
A scientist studying cold medicines hypothesizes that one particular medicine is more effective than the others in the study. He attempts the experiment several times. Each attempt produces a different result. What should he do next?
The scientist should give up since consistent results are not happening
He should change the data in his experiment in order to get the results he expected
He should determine whether the variation in his results are important through further investigation
He should prevent other scientists from attempting the experiment until he gets the results he expected
Elaine is studying the effect of sleep deprivation on motorists. The chart shows the reaction times of drivers she studied. What is the independent variable in Elaine's study?
The reaction time of each motorist
The stopping distance of each automobile
The type of vehicle each motorist is driving
The number of hours of sleep
Amelia is conducting an experiment to determine the effect of ultraviolet light on the growth of sunflowers. The graph shows the results of her experiment. According to the graph, what was the greatest growth Amelia observed?

Arash was experimenting with mold on bread. He used four types of bread: wheat, white, rye, and pumpernickel. Arash placed each slide of bread in a darkened room with stable temperature. He also placed the same four types of bread in a lit room at the same temperature as the dark room. What are the TWO independent variables?
https://www.brainpop.com/games/virtuallabstestingforcornmold/
type of bread & light
flavor of the bread & temperature
Amount of bread & light
Amount of mold & type of bread
When a new medication or technology is developed, scientists and society must evaluate the product's safety. Which of the following is an ethical way science and society work together to help balance the risks and benefits of a new medication?
If the risks are high, the new medication should be sold for less money
Scientists should not experiment with medications that could have side effects in humans
New medications should be released to the public without testing to relieve suffering as quickly as possible
Scientists must openly test the new medication on animals and on humans before making it available to everyone
A light shines on several different materials. The angle at which the light bends in each material is measured and then used to calculate the index of refraction. What is the independent variable in this experiment?
