Will more air inside a basketball make it bounce higher?
marysya [2.9K]

The outcome variable, test variable, and controlled variable for each question is as follows:

  • outcome variable = bounce height; test variable = volume of air, and  controlled variable = basketball
  • outcome variable = cleaning property; =  test variable = type of cleaner, and  controlled variable = cloth
  • outcome variable = heat absorbed; test variable = fabric color, and  controlled variable = amount of sunshine
  • outcome variable =  plant size, test variable = seed size, and  controlled variable = sunlight
  • outcome variable = flower freshness, test variable = sugar added to water, and controlled variable = sunlight
  • outcome variable = adhesion of tape; test variable = differences surfaces, and controlled variable = paper
  • outcome variable =  volcano eruption, test variable =  ratio of vinegar to baking soda, and controlled variable = container or bottle

<h3>What are variables in an experiment?</h3>

A variable is any factor in an experiment that can be manipulated, controlled for, or measured.

There are three types of variables in an experiment:

  • Dependent variable or outcome variable
  • Independent variable or test variable,
  • Constant variable or controlled variable

The Dependent variable or outcome variable depends on changes in the independent variable.

An independent or test variable is the variable that stands alone and is not affected  by other factors in the experiment.

The constant or controlled variable is unchanged.

The outcome variable, test variable, and controlled variable for each question is as follows:

1. Will more air inside a basketball make it bounce higher?

  • outcome variable = bounce height;  test variable = volume of air, and  controlled variable = basketball

2. Do ''green'' cleaners clean as well as store bought cleaners?

  • outcome variable cleaning property; =  test variable = type of cleaner, and  controlled variable = cloth

3. Which colors of fabric absorbs most heat?

  • outcome variable = heat absorbed; test variable = fabric color, and  controlled variable = amount of sunshine

4. Do bigger seeds make bigger plants?

  • outcome variable =  plant size, test variable = seed size, and  controlled variable = sunlight

5. Does sugar added to water improve cut flower freshness?

  • outcome variable = flower freshness, test variable = sugar added to water, and controlled variable = sunlight

6. How do differences in surfaces affect the adhesion of tape?

  • outcome variable = adhesion of tape; test variable = differences surfaces, and controlled variable = paper

7. What ratio of vinegar to baking soda produces the best chemical volcano eruption?

  • outcome variable =  volcano eruption, test variable =  ratio of vinegar to baking soda, and controlled variable = container or bottle

In conclusion, changes done to the test variable results in changes in the outcome variable.

Hypothesize how the properties of water protect the aquatic organisms living in a temperate-
xenn [34]

Answer:

Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.
