After selecting the three trials to compare, Linda measured the time it took for the ball to travel to the end of the ramp. She repeated each trial 10 times and recorded her data. What is the main reason Linda collected 10 measurements for each of the three trials? 

• to increase the reliability of her data 
• to list all the results in a table or graph 
• to change the experimental conditions
• to check that the equipment is working 

Which graphic representation would be the best way for Linda to display data from the three trials she tested? 

• histogram
• line graph
• double bar graph 
• stem and leaf plot

What is another question that Linda could test if she used the same materials as trials 1-5? 

• Do balls of different metals roll down the ramp faster? 
• B Would increasing the friction on the ramp decrease the speed? 
• Would increasing the length of the ramp change the speed of the ball?
• Does the size of the steel ball affect the time it takes to reach the bottom of the ramp?

 Maria wanted to measure the amount of time it took for a ball to roll down a ramp. She had never used a stopwatch before. Kevin gave her the following directions, but they were in the wrong order. Step 1: Hold the stopwatch in one hand. Step 2: Press the button once to start the clock. Step 3: Press the button twice to clear any old times. Step 4: Press the button to stop the clock. Step 5: Let the watch run until it is time to stop it. Step 6: Record the amount of time. How should she arrange Kevin’s steps so they are in the correct order? 

• 1, 5, 2, 3, 4, 6 
• 1, 2, 3, 5, 4, 6 
• 1, 3, 2, 4, 5, 6 
• 1, 3, 2, 5, 4, 6

Which statement best explains why bears are found in very cold regions of the world but lizards are not? 

• Bears and lizards depend on external sources of heat, but bears have fur to keep themselves warm. 
• Bears increase their body temperature to keep themselves warm when the outside temperature gets colder. 
• Bears maintain a constant body temperature through internal processes, but lizards depend on external sources of heat. 
• Bears and lizards maintain a constant body temperature through internal processes, but lizards get too cold when they shed their skins. 

Which figure represents a mixture? 

• Figure 1 
• Figure 2 
• Figure 3
• Figure 4

Jack bought a small turtle. Three months later, the turtle had grown to twice its original size. Which of the following statements best describes why Jack’s turtle got bigger?

• Parts of the turtle stretched out as it grew larger. 
•  The number of cells in the turtle’s body increased. 
• The turtle’s body absorbed the food it ate and water it drank. 
•  The size of each cell in the turtle’s body got bigger as it got older.

Steven went to a farm and picked a bright red tomato from a broken branch on the plant. The tomato had a rotten spot with a worm inside of it. Instead of eating the tomato, Steven decided to plant the seeds and grow new tomato plants. Which characteristic of the tomato plant is inherited and could change over several generations?

• size of rotten spots

• color of the skin

• length of worms inside

• number of broken branches

What is the best question for students to investigate that would help explain the results of this demonstration? 

• How long did it take for the cube in Beaker 2 to sink?
•  Would a different sized beaker provide the same results? 
• Will the cube in Beaker 1 sink if more liquid was added? 
• What caused one cube to float and the other cube to sink?
