Libby did an experiment to see what type of food her parrot liked best. Each day, she fed her parrot the same amount of food at the same time. She gave her parrot four different brands of seed mixes: one each week, for four weeks. She measured how much of the seeds were not eaten each day. What procedures in Libby's experiment allowed her to collect accurate data?
She kept the conditions for the experiment constant.
She didn't stop the experiment once she had started it.
The mixes all contained the same type of seeds.
She used her pet parrot instead of a wild parrot as the test subject.
Avi is comparing two brands of batteries. He uses two identical flashlights to see which battery lasts longer.
Why is it important for this experiment to be repeated?
To check whether the results are consistent.
To make sure the flashlights were not broken.
To check that no one turned off one of the flashlights.
To make a prediction about a different brand of battery.
Sam and Will are investigating the kinds of flowers that attract butterflies. They identify a common butterfly species that lives in their area and has been identified on their school campus. They visit the school's butterfly garden and count the number of times these butterflies visit three different types of flowers. What is the best reason they should take careful notes about how they carry out their investigation?
So they don't leave out any steps.
So they can take out information they do not like.
So their conclusions can be checked by another student team.
So they can decide whether they want to finish their investigation.
Max conducted an investigation to determine whether laurel oak trees would grow in very cold weather.
Which of his observations is scientifically testable?
The bark of young laurel oak trees feels particularly smooth in very cold weather.
Young laurel oak trees do not grow to look as nice in cold weather as when the weather is warm.
Young laurel oak trees do not like frost.
Young laurel trees produce fewer new leaves in very cold weather, rather than in warm weather.
Jason performed an experiment to find out how well mold grows on different types of food. He left a piece of bread, a piece of cheese, and an apple cut in half on the lab table in his science classroom. Every day when he went to science class, he observed the mold growing on the different samples. Then he wrote down his observations. His data showed that the cheese and bread were nearly covered in mold after a week. Jessica decided to repeat Jason's experiment. Her data showed that after two weeks, there was no mold on any of her samples. Which of the following should Jessica do first?
Repeat her experiment until she gets the same results as Jason.
Research mold on the Internet.
Review the records of both experiments to see whether they used the same procedures.
Write a paper on her findings and present it to her science class.
A scientist conducted an experiment to determine whether dogs that eat sugary foods will develop more health related illnesses. Which of his observations is scientifically testable?
Dogs that eat sugary food become less friendly.
Dogs that eat sugary food get sick more often.
Dogs that eat sugary food do not grow beautiful hair.
Dogs that eat sugary food get smarter.
Shelly is doing an experiment to determine the effect of fertilizer on bean plants. She is going to test four plants as shown in the table.
Which variable is Beth testing?
Brand of fertilizer used.
How often the plant is fertilized.
Amount of fertilizer used.
Time of day the plants are fertilized.
Elijah wanted to record how two mockingbirds in his backyard were competing with one another for food and space. He observed and recorded data on the interactions between the two mockingbirds every week for a month. Which of his notes provides evidence to support his question?
The mockingbird with the bigger beak chased off the other mockingbird more often.
The mockingbird with the bigger beak doesn't like me watching them.
The mockingbird with the smaller beak seemed less hungry.
The mockingbird with the smaller beak never sings.
Max performed an experiment to determine which insulating material would work best for a container of hot water. He discovered that when he wrapped wool fabric around a glass of hot water, the water stayed hot longer than when it was wrapped with an equal mass of cotton fabric. He wonders whether his data is accurate.
What can Jim do next to determine whether his data is accurate?
form a new question
draw a conclusion
start collecting data
repeat the experiment
Patrick is researching the differences between swamps, deserts, and tundras on the Internet. Which website most likely contains reliable information for him to use?
website run by a government land management group
website run by a sports fishing magazine
website run by a fifth grade class
website in which questions are asked and readers supply answers
Amy wants to find out whether hamsters grow faster when they eat Hamster-Pro Food or Acme Hamster Food. She separated the hamsters at her parents' pet store into two groups. Then she placed each group into different enclosures. She fed one group Hamster-Pro Food and the other group Acme Hamster Food. She kept careful records of her observations and measured the average weights of the two groups of hamsters for three weeks.
What can Amy do to make sure her results are accurate?
Feed hamster more food than the other hamsters
Repeat the experiment with the same foods
Read the information on the food bag
Try two completely different brands of hamster food

Gordon left his house at 8:00 AM. As he drove up the mountainside, his elevation increased (height above sea level) and the car's thermometer showed the outside temperature was getting colder. Stefan wondered if the temperature would continue to change as he drove higher up the mountain. He decided to do some research to find out.
Which part of scientific inquiry will Gordon NOT use to investigate the relationship between temperature and elevation?
collecting data
forming a question
controlling variables
analyzing information
