Kelsey estimates that people with long legs can run faster than people with short legs. To test her idea, she chooses a group of ten classmates. Then she records the lengths of each of their legs in a chart. Next, she has each classmate run around the school track as fast as possible. She records each person’s time in a chart. Kelsey concludes from the data she has collected that longer leg length doesn’t always result in faster running time. What should Kelsey do if she want to learn why some people with long legs might run more slowly than people with short legs?
Change her estimate for this experiment
Perform a different experiment using the same group of ten classmates
Repeat the same experiment with a new group of classmates
Draw a different conclusion from her data
Michelle has two glasses of juice. She puts one in the freezer for seven minutes and the other in the refrigerator for 20 minutes. Which tool can Michelle use to find out which glass of juice is the coldest?
A balance

A scientist set up containers to collect water in three spots around town. He wanted to find out how much rain falls in each area. What should the scientist record when looking at each container?
The number of organisms present in each container.
The amount of rainwater in each container.
The color of the rainwater in each container.
The temperature of the rainwater in each container.
Miranda is investigating the amount of light that pea plants need to grow. She plants three pea plants in different pots: one plant outside in direct sunlight, one plant outside in full shade, and one plant outside in a partial shade. In order to perform the experiment correctly, what must Miranda do next?
Plan more experiments with pea plants.
Try to guess which plant will grow fastest.
Add more plants in each location.
Write down the height of each plant every day.
Micah would like to know whether eating breakfast affects a student’s performance on a test. On the day of a Science test, Micah asked all of his classmates whether they had eaten breakfast. He recorded their answers. Then he recorded their grades on the Science test. He determined that students who had eaten breakfast scored and average of 88 on the Science test. Students who had not eaten breakfast scored an average of 84 on the Science test. Micah plans to gather more data by interviewing his classmates before science tests throughout the year. Which of the following is NOT a step in Micah’s investigation?
Asking students questions
Recording results
Reporting findings
Taking science tests
Bryce and Jay were doing an experiment in school. They had completed their experiments and collected all their data. Now they were ready for the final step, except they could not remember what to do with all the information the had gathered. What should Bryce and Jay do with their information?
Conduct a different experiment
Estimate what might happen in this experiment
Analyze the data and form a conclusion
Predict what will happen in a similar experiment
A student conducts an experiment in which 7 pea plants are each given a different amount of water. The student observes and records the growth of each plant every other day. After 6 weeks, the student sees that Plant C grew the least. What would be the most effective way to visually present the data to other students?
Comparison line graph
Written report
Pie chart
Scatter plot graph
Dwayne wanted to know if some liquids freeze more quickly than others. How should he figure this out?
Freeze two liquids in different containers.
Freeze one liquid in two different containers.
Freeze two liquids after mixing them in one container.
Research how long it takes water to freeze on the internet.
Linh has four different candles with different scents. She would like to know which candle will burn the longest. How can Linh determine which candle burns the longest?
Measure the height of each candle and conclude that the shortest one will burn fastest.
Measure the temperature of the wax of each candle with a thermometer as the candles are burning.
Measure the mass of each candle before and after 30 minutes of burning.
Measure the length of the wicks of each candle.
Tyrone is conducting an experiment that investigates the heart rates of girls and boys in the fifth grade. He measures the heart rates of 25 subjects every day for one week. At the end of the week, he divides the data into two groups according to gender. He then analyzes the data to find the average hear rate of each group. What is the purpose of forming a conclusion at the end of experiment?
The conclusion states a theory to law based on the results
. The conclusion summarizes the results of the experiment.
The conclusion reports the way the experiment was performed.
The conclusion asks new questions about the subject matter
