The students collected different small organisms from the pond. Which tool would be most useful for studying those organisms from a pond?
balance
pH meter
microscope
thermometer
Rica wants to investigate factors that affect the different patterns of flight of the hummingbirds. What step is first done before forming a hypothesis?
record data
measure the variables in the experiment
draw a conclusion
gather information about flight patterns
Moses obtained two identically sized plants of the same type. He then placed them in the same room. One plant was placed near a window on the opposite side of the room. The plants were given identical amounts of nutrients and water. Which statement most likely expresses the hypothesis being tested in this investigation?
The same kind of light enters different windows.
Different wavelengths of light change the growth of a plant.
Different windows allow different amounts of light to enter the room.
Plants grow to different sizes if exposed to different amounts of light.
Joel proposes that the rate of increase in plant's mass will be proportional to the length of light exposure per day when all other variables are constant. How should this proposal be classified?
Hypothesis
Conclusion
Theory
Statement
First block students measure the effect of water on the growth of plants for a lab experiment. The students give different amounts of water to three different groups of plants. All plants receive the same amount of light and are planted in the same amount of soil. The students then measure the height of the plants over a period of four weeks. Which variables should be labeled on the axes to graph the data collected in this experiment?
Amount of Water vs. Height of Plants
Temperature vs. Amount of Sunlight
Amount of Water vs. Amount of Soil
Amount of Sunlight vs. Height of Plants
Researchers grew some bacteria in a lab and tested them in several trials. Their results are shown in the table. Which trial shows the control group?
1
2
3
4
Michael investigates whether light intensity affects the rate of photosynthesis in one type of plant. Monique created this graph based on her data.
As light intensity increases, how is the rate of photosynthesis affected?
It increases continuously.
It decreases continuously.
First it increases and then decreases.
First it increases and then becomes constant.
Jennifer wants to describe the trend in bacterial cell division over time.
Which conclusion is most accurate for the student to make?
The rate of division increases rapidly and then levels off.
The rate of division starts slowly and gradually increases.
The rate of division increases rapidly and then stops.
The rate of division accelerates constantly over time.
Based on the picture and chart below, which characteristic are these three types of poodles specifically bred for?
size
color
coat length
retrieving ability
An advertisement has this graph in it to convince people that Brand Y is far more popular in a blind taste test than Brand X.
Which of the following can be concluded from this graph?
Fifteen more people preferred X to Y.
Fifteen more people preferred Y to X.
Four times as many people preferred X over Y.
Four times as many people preferred Y over X.
Which instrument should a student use to best examine bacteria?
telescope
hand lens
microscope
computer probes
Aphids are insects that are harmful to citrus trees. They feed on new growth and cause the leaves to curl and twist.
Aphids feed in large groups for protection from predators.
The curled leaves are inefficient energy producers.
The curled leaves are unattractive to new aphids.
Aphids are unaffected by the use of pesticides.
Microhabitats are small, specialized habitats within a larger ecosystem. A science class was investigating microhabitats within a temperate forest ecosystem. Their results are recorded in the table shown.
Which is the best way to show the number of organisms in each microhabitat?
line graph
scatterplot
pie chart
pictograph
A scientist sampled 6 types of plant life found in a prairie by counting the number of each type found in a 1-m2 plot.
What would be the best way to visually represent these data?
bar graph
line graph
pie chart
scatterplot
A student studied the growth of mold on strawberries. One container of strawberries was vacuum-sealed to remove the air and the other container was covered by plastic wrap. Both containers were placed in the refrigerator. After two weeks, the vacuum-sealed strawberries contained less mold than the plastic-wrapped strawberries. Which is the best conclusion based on these results?
Mold cannot grow on strawberries that have been vacuum sealed.
Mold spores were on the strawberries before they were covered or sealed.
Mold grows best on strawberries stored covered and kept in a cool place.
Mold spores grow more easily on strawberries wrapped in plastic than on those that are vacuum sealed.
