FCAT Review #1

Hawks are born with the ability to fly very fast so that they can catch their prey. This is called —

• desire

• hunger

• swiftness

• aerodynamics

Based on evidence in the graph, what was most likely the population of orangutans in 2014?

• 6,500

• 7,000

• 5,000

• 2,000

J.P. and Rosa investigate ways to grow tomatoes. They use three types of tomato plants and different amounts of fertilizer. They water each plant with 20 mL water every other day. They recorded the growth rate of each plant in the table below. Growth (cm): Big Boy, Roma, Beefsteak. Week 2: 5 cm, 3 cm, 5 cm. Week 4: 12 cm, 5 cm, 13 cm. Week 6: 16 cm, 9 cm, 18 cm. J.P. and Rosa decide that the Big Boy and Beefsteak tomatoes grew best, but their results cannot be reproduced. Which mistake did they make?

• J. P. and Rosa would have had better results if they only used one type of tomato.

• Every plant is an individual, just like people. So, some grow faster than others.

• J. P. and Rosa needed to water their tomato plants every day to be more successful.

• J.P. and Rosa needed to use the same amounts of fertilizer for each type of tomato.

Based on this evidence, which percentage of energy used in 2015 came from renewable resources?

• A 26%

• B 29%

• C 43%

• D 69%

Several students took part in a bird census for the month of October. Each student wrote a report to summarize their findings. Which has the most accurate empirical observation from their census?

• Jake: There were plenty of birds flying north on Saturday.

• Carla: I saw three types of birds I could not recognize.

• Jun: I counted 42 tree swallows and 112 purple martins in three hours.

• Esteban: Most of the birds I saw, like ducks and flamingos, live in Florida all year long.

Mr. Howell's fifth grade is making homemade lava lamps. Each student is given the same materials: one clean, clear 600 mL soda bottle with a plastic cap; two fizzy antacid tablets; food coloring; 100 mL of vegetable oil; and 500 mL of water. They follow a set of specific instructions and record their results in their science notebooks. What makes this a replicable, or repeatable, experiment?

• Every student received a set of instructions.

• All students recorded the steps in a science notebook.

• Everyone in the class is making his or her own lava lamp.

• The materials were measured out and added in the order listed in the instructions.

Which contains empirical evidence about the climate in Tallahassee?

• Tallahassee has hot, humid summers and cold, dry winters.

• Last January, Tallahassee experienced a week of freezing weather.

• In Tallahassee, there is less rain in January than in June or July.

• The average daily temperature in Tallahassee in January is 63.5 °F.

Tran is doing an investigation that involves heating water. He wants to see how long it takes for the water to boil. Is this the correct tool to use?
Choose all that apply

• Yes, it is a thermometer and measures heat.

• No, the thermometer only goes to 50°C, which is not the boiling point of water.

• Yes, when the thermometer reads 0°C, the water is boiling.

• No, this thermometer is for use in a refrigerator where meat is kept cold.

Jenna goes to the doctor who looks at her throat, swabs it, and sends the swab to a laboratory. The technician observes bacteria. The doctor gets the report and writes a prescription. Which produced empirical evidence?

• The doctor looks at her throat.

• Her doctor takes a swab and sends it to a laboratory.

• The laboratory technician observes bacteria on the slide.

• The doctor gets the report and writes a prescription.

As part of an experiment, Jenna measured the mass of the red cube. Which best describes why she should record her experimental procedure?

• The exact experiment can be repeated by others, and the results can be compared.

• The data will help others to find other properties of the red block.

• By writing down her procedure, she does not have to tell anyone about her experiment.

• Others can change the experiment to get different results.
