Question

the variables for part i of this experiment include the types of materials used in the cup, the masses of these materials, and their temperatures over time. use the drop - down menus to complete the sentences and identify the independent and dependent variables. the two dry sand samples are examined by changing one parameter. the independent variable, the one that is intentionally manipulated between the two samples, is the. besides the amount of material, there is also another variable that is manipulated within each of the two mass groups and represented as three types. this independent variable is the. in each case, the dependent variable, the one that you measure the response in, is the.

Explanation:

• The first blank: When examining two dry - sand samples by changing one parameter, if we are comparing samples of different amounts (masses), the mass is the variable that is intentionally changed.
• The second blank: If within each mass group, there are three types (e.g., different types of dry - sand materials like fine sand, coarse sand, etc.), the type of material is the variable being manipulated.
• The third blank: In an experiment where we are looking at how changes in mass and material type affect something, the temperature over time is what we measure (the response), so it is the dependent variable.

Answer:

The first blank: mass.
The second blank: type of material.
The third blank: temperature over time.
