Does The Temperature Of The Respiration Rate Affect The Fish?

The dependent variable in the experiment was the temperature and energy absorbed by the water.

This lab was about how a goldfish’s breathing rate changes in different temperatures in order to maintain homeostasis.

The only dependent variable is the time the ice cubes take to melt. The controlled variables are the size of the ice cube, and the room conditions they melted in. Aim: To see which type of ice cube melts faster (the one with or without sugar).

Research Question: This investigation will determine the how the amount of water (independent variable) affects the amount the amount of time (dependent variable) it takes for the Alka-Seltzer to dissolve.

1. For this experiment, what were the independent variable and the dependent variable? What were the constants?

At the conclusion of the experiment, the two hypotheses were reviewed. Because the water temperature did affect the normal respiration patterns of the goldfish, the null hypothesis was disregarded and the alternative hypothesis was accepted. From the results of this experiment, it was concluded that although other environmental factors could play

The independent variable for the experiment was the paper towels. The dependent variable was the absorbency and strength. The constants for the experiment were the size of the paper towels that were used, the amount of water, the size of the beaker, the size of the cylinder and the amount of the weight.

The purpose of this lab was to save a little gummy worm named Sam from drowning. In addition, one of the labs key terms was a hypothesis which is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation. Furthermore, we also learned that an independent variable is a factor that is changed during the experiment. On the other hand, the dependent variable is the factor that is observed or measured during the experiment. To begin with, the experiment the hypothesis formulated was if we reshape the paperclips into hooks and pick up sam, and the lifesaver (without touching them), then the lifesaver would be stretched enough for Sam to go through it.

2. You have measured the rate at which a fish breaths at various temperatures by counting the rate at which its gills open. The data table is shown below. Create a line graph depicting the results.

Dependent: The dependent variable is the time as it will be the aspect being measured and recorded.

13. Which of the following is not an expected response in a fish to a drop in water temperature?

4. The Independent variable is the dissolved oxygen and the dependent variable is the number of fish observed.

The reaction time (in seconds) is the dependent variable of this experiment. This will be changed by the temperature of the chemicals, and as it is affected by the independent variable it is considered the dependent variable.

Independent variableIdentify the independent variable (IV), which is the variable that you hypothesize will cause or influence the other variable. *

Depth of water: The amount of water will be changed by 1 cm for every data point. (There are 9) This will be measured in height in order to get the most accurate
