According to recent temperature trends in New York City, one might predict which temperature on day 7?

• 59

• 83

• 67

• 72

Jane is setting up an experiment involving bean plants. She places a bean inside a damp paper towel, then places it inside a Ziploc bag. She takes another bean but places it inside a dry paper towel. She tapes both Ziploc bags to her classroom window next to each other. She checks each day to observe and record the data. Jane is most likely invesitgating which hypothesis:

• Beans cannot grow in a paper towel.

• Amount of sunlight affects how fast beans grown.

• What does a bean look like once it's sprouted?

• A dry bean grows quicker than a damp bean.

Which question is the experiment most likely designed to answer?

• What are the effects of water on plant growth?

• What amount of fertilizer is best to use for plants?

• How does the height of a plant affect how much sunlight it needs?

• How does the amount of sunlight a plant receives affect its growth?

A scientist studied two species of sea snail and recorded the physical characteristics in the data table. Which conclusion about the data is based on correct reasoning?

• If a snail she studied had a brown shell, then it was a red foot snail.

• If a snail she studied had a brown shell, then it had a white underside.

• If a snail she studied was 175 millimeters long, then it had a white underside.

• If a snail she studied was 125 millimeters long, then it was red foot snail.

A scientist studying a species of flower that grows on the side of a mountain measured the height of many of the flowers at different elevations. His results are shown in the graph. Which statement best describes the pattern of growth for the flowers during this experiment?

• The flowers cannot grow below elevations of 1,000 meters.

• The flowers’ heights increase with higher elevation.

• The flowers’ heights are unaffected by elevation.

• The flowers grow taller at elevations of around 3,000 meters.

Which question could Julie answer most easily by conducting a scientific experiment?

• Does the mass of an ice cube change when it melts?

• How long does it take for water to freeze?

• What is the temperature of the water?

• Does ice melt faster in air or in water?

Chris wanted to determine the effects of a soil pollutant on the growth of a sunflower plant. He designed an experiment and recorded his results in the data table. Where does Chris make a mistake in the design of his experiment?

• The amount of water should be the same for each plant.

• The amount of sunlight per day should be different.

• The amount of pollutant should be the same for each plant.

• The experiment should use more types of plants.

Rachel wonders how the number of ice cubes added to a glass of juice affects the temperature of the juice. She wants to design an investigation that tests this question and that will produce clear, repeatable results.

Which data table shows the best experimental design? A, B, C, or D?

• 
• 
• 
• 

Which of the following describes the relationship between the wavelength and the transmittance?

• As wavelength increases, transmittance increases.

• As wavelength increases, transmittance decreases.

• As wavelength increases, transmittance stays constant.

• There is no relationship between wavelength and transmittance.

In the year 2750, which set of days will be the closest estimate for how long the season of the autumnal equinox or fall will last?

• 93. 5 days

• 92. 5 days

• 90.5 days

• 88.5 days
