During hibernation, an animal is not active for a long period of time. As an animal hibernates, its heart rate and body temperature both decrease. Bears are one animal that hibernates. Hibernation is an adaptation because:
A. each bear chooses if it wants to hibernate or not.
B. each bear that hibernates can live in different types of forests.
C. in a group of bears living in the same area, the bears that hibernate are less able to survive and produce less offspring than the bears that do not hibernate.
D. in a group of bears living in the same area, the bears that hibernate are better able to survive and produce more offspring than the bears that do not hibernate.
Scientists have evidence from fossils that early horses had 3 toes. Horses today have 1 toe. Which of these claims can be best supported by this evidence?
A. More horses with 3 toes survived to produce more offspring than horses with 1 toe.
B. More horses with 1 toe survived to produce more offspring than horses with 3 toes.
C. Horses with 3 toes required more food than horses with 1 toe, so fewer survived to produce offspring.
D. Horses with 1 toe required more food than horses with 3 toes, so fewer survived to produce offspring.
Which word best describes a single feature an animal has that helps it to survive in its surroundings?
A. biome
B. niche
C. adaptation
D. selection
Look at Table 2. The dark chocolate took 7 minutes to completely melt in which trial?
Trial 5
Trial 6
Trial 7
Trial 8
Look at Table 1. The milk chocolate took 14 minutes to completely melt when the distance between the chocolate and the lamp was:
6 cm.
8 cm.
10 cm.
14 cm.
Which of these things was kept the same in Trials 1–8 ?
The distance between the chocolate and the lamp
The kind of chocolate that was melted
The mass of chocolate that was melted
The time taken to completely melt the chocolate
Look at Table 1 and Table 2. The kind of chocolate that completely melted in the least amount of time was the:
dark chocolate that was 4 cm from the lamp.
dark chocolate that was 10 cm from the lamp.
milk chocolate that was 4 cm from the lamp.
milk chocolate that was 10 cm from the lamp.
Look at Table 1 and Table 2. The milk chocolate that was 6 cm from the lamp took the same amount of time to completely melt as the:
dark chocolate that was 4 cm from the lamp.
dark chocolate that was 8 cm from the lamp.
milk chocolate that was 4 cm from the lamp.
milk chocolate that was 8 cm from the lamp.
Suppose 15 grams of the dark chocolate had been placed 12 cm from the lamp. Look at Table 2. The time taken to completely melt the dark chocolate would most likely have been:
less than 7 minutes.
between 7 minutes and 10 minutes.
between 10 minutes and 17 minutes.
greater than 17 minutes.
Look at Table 2. On which day did the wind blow from the south?

Tuesday, Thursday, Monday, Wednesday, Friday
Tuesday, Monday, Wednesday, Thursday, Friday
Friday, Thursday, Monday, Tuesday, Wednesday
Friday, Tuesday, Thursday, Monday, Wednesday
Look at Table 2. What was the total amount of rainfall measured, if any, for all 5 days?
0 inches
1 inch
2 inches
3 inches
Which of these correctly matches a tool with its unit of measurement?
Anemometer and °F
Anemometer and inches
Rain gauge and °F
Rain gauge and inches
The arrow on a weather vane points in the direction from which the wind blows.
When the wind was measured on Friday, in what direction did the arrow most likely point?
North
East
South
West
A student claimed that days with temperatures less than 50°F will have winds that blow from the north. Do the measurements in Table 2 support the student’s claim?
Yes; Friday had a temperature less than 50°F and wind that blew from the north.
Yes; Friday had a temperature less than 50°F and wind that blew from the south.
No; Friday had a temperature less than 50°F and wind that blew from the north.
No; Friday had a temperature less than 50°F and wind that blew from the south.
Look at Table 2. What was the smallest number of drops needed for Taylor to smell the orange juice?
0
1
2
3
Which of these scientific tools was most likely used to add the hot sauce to the cups in Experiment 3 ?
Dropper
Ruler
Scissors

Which of these things did Mrs. Yee change in each experiment?
The liquid being tested
The person smelling the liquid
What the cups were made of
What volume of water was in the cups
What total volume of water did Mrs. Yee use in Experiment 1 ?
100 mL
200 mL
300 mL
400 mL
A student claimed that more drops of vanilla than of orange juice would be needed for Taylor to smell each liquid. Which experiments tested this claim?
Experiments 1 and 2 only
Experiments 1 and 3 only
Experiments 2 and 3 only
Experiments 1, 2, and 3
Suppose that in Experiment 3, Mrs. Yee had added 5 drops of hot sauce to a cup holding 100 mL of water. Would Taylor most likely have smelled the hot sauce in this cup?
Yes; Taylor smelled the hot sauce in Cup L.
Yes; Taylor smelled the hot sauce in Cup N.
No; Taylor did not smell the hot sauce in Cup J.
No; Taylor did not smell the hot sauce in Cup K.
