What causes a handle of a pot to be hot when a pot is heating on a stove?
What causes a handle of a pot to be hot when a pot is heating on a stove?
Let's look at the terms from our answer choices to help us answer this question:
Physical properties are things that can be observed; such as, texture, color, etc.
Energy is the ability to do something.
Transmission is when energy passes from one object to another.
Conduction is when heat is transferred from one object to another object.
When a pot is heating on a stove, the pot is in direct contact with the heat source. The handle of the pot is in contact with the pot, and the heat can be transferred from the pot to the handle, which causes the handle to be hot.

Select the property that is not a physical property.
Select the property that is not a physical property.
Physical properties are properties that can be obtained without permanently changing the original substance. By looking at something, we can see the color, feel the texture, and measure the weight without changing the substance; thus, all of the choices are correct.

Select the property that is not a physical property.
Physical properties are properties that can be obtained without permanently changing the original substance. Without changing a substance permanently we can measure the boiling point, melting point, and freezing point. However, to determine heat of combustion you must premaritally change the substance.

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.
What will Ashley measure to determine which car was the fastest?

What will Ashley measure to determine which car was the fastest?
Ashley will be investigating which car gets down the ramp in the least amount of time. The keyword "time" in that statement gives a clue to which answer choice would be the correct measurement. The only answer choice that measures time is, "Ashley will measure the time it takes for each car to go down the ramp.". This choice would collect information about each car so their times can be compared. The vehicle with the least amount of time would be the car that travels down the ramp the fastest.

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.
Which tool would be best for measuring the object's movement?

Which tool would be best for measuring the object's movement?
The tool that would be most appropriate for measuring would be a ruler. This investigation is measuring distance so that would narrow the choices down to a ruler or the meter stick. A meter stick measures things that are a longer-distance, and a marble is not going to move a cup that far. A ruler would be sufficient for this investigation.

Which tool should they use to collect this data?
This experiment is testing which pants' material will slide the fastest. This is a measurement of time and speed. The tool that would be the most appropriate would be the stopwatch. 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.

What would be the most appropriate tool to measure the weight or mass of the marbles in the data table below?
This data table shows the marble's weight is in grams. To measure the marble accurately, a scale should be used to find its weight or mass. A beaker and measuring cup would be more appropriate for liquids, and a ruler measures length. A scale or balance would be the best option for weight or mass.

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.

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.

Observations are critical in an investigation because scientists are recording what they see, and they measure to collect data for evidence. The observations help support the conclusion that is made. For Ashley's investigation, the most reasonable observation would be, "The toy cars on the grass and carpet moved very slowly, if at all. The cars on the wood and plastic moved quickly. The car on the plastic got down the ramp in the least amount of time.". This statement includes information about which cars move slowly, quickly and the fastest. The data collected sounds reasonable, cars on wood and plastic would move swiftly, and vehicles on grass and carpet would move slowly.

What observation can be made regarding the motion of this object after being rolled on a curved ramp?
What observation can be made regarding the motion of this object after being rolled on a curved ramp?
This investigation consists of dropping the ball onto one side of the ramp and then measuring the height each time the ball reaches the opposite side. When looking at the visual and the data table, it can be observed that the height decreases with each roll. The tick marks show the ball ending up in the center by the fifth roll, and the data table shows a steady decline in the numbers.

Each time the ball completes a roll, it decreases in height. What increment is it reduced by with each turn?
Each time the ball completes a roll, it decreases in height. What increment is it reduced by with each turn?
Each time the ball completes a roll, its height is reduced by 2 inches. Simple subtraction can be used to find the difference between each turn. This information can be used to make a production about future trials or the missing fifth roll.

Based on the data table below what could Ruben observe about the movement of the cup?
This data table organizes information and measurements collected during an investigation of an object's motion. The cup moved every time a marble was rolled into it. An accurate observation that could be made is that the heavier the marble was, the further the cup traveled. A pattern can be seen as the marble's weight increases; the distance the cup travels increases as well.

How do objects move?
How do objects move?
Force can make things move, change shape, or change their speed. Some forces are direct and happen when two things touch (like pushing a friend on a swing) or other happen over a distance (such as a magnet drawing a paperclip closer). Objects only move when there is a force acting on them.
