Example Question #3 : Make Measurements Of An Object's Motion
Jamarcus is experimenting at his local playground. He and his friends are all wearing pants made of different materials. They want to see which type of pants will move down the slide quickest.
What would be the best way to take measurements and determine which pants slide the fastest?
Jamarcus and his friends should measure the distance from the top of the slide to the bottom of the slide. They should record the measurement and then determine which person is the shortest.
Jamarcus and his friends should start timing each person as they begin sliding to when they reach the bottom. They should record the measurements and then compare them to see which material had the longest time.

Jamarcus and his friends should measure the distance from the top of the slide to the bottom of the slide. They should record the measurement and then determine which person is the tallest.
Jamarcus and his friends should start timing each person as they begin sliding to when they reach the bottom. They should record the measurements and then compare them to see which material had the shortest time.
This experiment is testing which pants' material will slide the fastest. This is a measurement of time and speed. The boys could time each person from the top of the slide to the bottom to determine who's pants help them to slide the fastest. The person with the lowest time is the material that allows the quickest slide.
Example Question #4 : Make Measurements Of An Object's Motion
If a student wants to observe and measure an object's motion, he can take measurements of the object's _______________.
None of the answer choices are correct.
time
All of the answer choices are correct.
speed
distance traveled
All of the answer choices are correct.
If the student wishes to make observations about an object's motion, taking measurements is an excellent way to record the data and draw conclusions. The student could measure the speed of the objects, its distance traveled, or the amount of time it was moving. All of these answer choices are appropriate measurements.
Example Question #3 : Make Measurements Of An Object's Motion
There is no way to measure an object's motion. When something is moving, it cannot be measured.
False
True
False
The statement in the question is false. Objects can be measured when they are in motion. The object's speed is one example of a measurement that can be taken while the object is moving. Think about a baseball game, they record the speed of the ball and display it on the screen every time a pitcher throws the ball. In car races, the speed of the cars is measured to determine how fast they are traveling.
Example Question #5 : Make Measurements Of An Object's Motion
Cindy rolls a marble down a ramp and hits a cup waiting on the bottom. She does this multiple times with different size marbles. After each roll, she measures the distance the cup traveled.
What would be the best unit of measurement to use when she records her data?
Pounds
Inches
Millimeters
Miles
Inches
Taking measurements is critical when completing an experiment or investigation. The data collected through measurements can be used to draw conclusions and make recommendations. Patterns are often found in the measurements obtained, and this helps scientists to make predictions. In the investigation that Cindy is performing, the best unit of measure would be inches. Pounds wouldn't be appropriate for measuring distance, and miles are too large of a unit for something like a rolling marble. Millimeters are a tiny unit of measure, and it would be difficult to use them to measure. Inches would be the most appropriate.
Example Question #21 : Predictions Of Future Motion Through Patterns
Ashley wants to investigate how objects move and see if she can make correct predictions. She knows she will have to observe the object's motion. She wants to see which surface material will allow a toy car to get down a ramp in the least amount of time. She tests the car on wood, plastic, carpet, and grass.
Using the collected data, which answer choice states a pattern that can be identified regarding the car's motion?
The car on the plastic surface went down the ramp slowest two out of three trials.
The car on the plastic surface went down the ramp fastest one out of three trials.
The car on the plastic surface went down the ramp fastest two out of three trials.
The car on the plastic surface went down the ramp slowest of the trials.
The car on the plastic surface went down the ramp fastest two out of three trials.
There is more than one pattern that may emerge from data collected during experiments or investigations. In this investigation, Ashley could see a pattern with the car that rolled down the plastic surface. The car on the plastic ramp rolled down the fastest two out of three trials. Ashley could conclude that this car went down the ramp the fastest.
Example Question #22 : Predictions Of Future Motion Through Patterns
Using the patterns within the data table below, predict the motion of the ball on bounce 4.
0
5
10
7
5
Data collected during experiments or investigations are a great way to look for patterns. In this experiment, there is a bounce (motion) that is measured in inches. Using the trends in the table, we can predict what the next measurement will be. The ball decreases it's bounce by five inches each time, so we can predict that the final bounce will be five inches.
Example Question #23 : Predictions Of Future Motion Through Patterns
A ball is released at the top of a curved ramp, as seen below. Each time the ball reaches the opposite side, it is measured and recorded. Based on the patterns in the data, what would the ball's measurement be on the fifth roll?
3
2
1
0
0
Patterns often emerge in collected data that help us to make predictions about future motion. In this investigation, the measurements are decreasing in two-inch increments. Based on this information, it can be predicted that the final measurement, number five, will be 0 inches. The ball does not gain any additional momentum during its time rolling, only decreasing. The increments are steady so that a pattern can be interpreted for future measurements.
Example Question #24 : Predictions Of Future Motion Through Patterns
Sally and Reina collect data during an experiment and believe that they can use patterns to predict the future motion of objects. Based on the data table below, what can they predict will happen with a marble that weighs 50 grams?
The cup will move less than five inches.
There is not enough information to make a prediction.
The cup will move further than five inches.
The cup will move five inches.
The cup will move further than five inches.
This data reveals a pattern about the cup's motion based on the measurements taken. The cup moves a greater distance as the marble's weight increases. An appropriate prediction would be that the cup would move farther than five inches if the marble were to weigh 50 grams.
Example Question #25 : Predictions Of Future Motion Through Patterns
How far would the cup travel if a 50-gram marble were rolled into it based on the patterns in the data table below?
15 inches
7 inches
5 inches
9 inches
9 inches
If a 50-gram marble were rolled into the cup, the distance would increase. There is a pattern between the weights of the cup and the movement. Each time the mass of the cup is increased by ten grams, the cup moves two inches. If using the logic created by this pattern, a 50-gram marble would move the cup a total of nine inches. A 40-gram marble would move the cup seven inches (5+2=7), so another ten grams would mean another two inches added (7+2=9) totaling nine grams.
Example Question #1 : Use Collected Data To Show Patterns In Motion
Jill wants to investigate how objects move and see if she can make correct predictions. She knows she will have to observe the object's motion. She wants to see how high different bouncy balls will go on the same surface.
If Jill performs the fourth trial, what prediction can be made about "Ball 3"?
There is no way to predict what "Ball 3" will do during Trial 4.
"Ball 3" will most likely bounce the highest distance during Trial 4.
"Ball 3" will most likely bounce the shortest distance during Trial 4.
The ball will no longer bounce because it has been used too many times.
"Ball 3" will most likely bounce the shortest distance during Trial 4.
Jill can make predictions about what will happen in future trials because there are patterns in motion that data helps us to recognize. "Ball 3" bounced the shortest height in all of the previous tests, so, likely, it will again bounce the shortest height. Using patterns and data can help support the prediction that she is making.
