Results

There is a relationship between birds and mammals in terms of body mass and BMR. The greater the body mass, the greater the BMR and vice versa.

There is also a relationship between the body length and BMR of mammals, the greater the body length, the greater the BMR.

After reading about how age can sometimes be determined by BMR and other components that come into play, why not question more?

BMR is basal metabolic rate.

We are looking for relationships between the body masses of birds and mammals along with their BMRs. We are also looking for any relationship between body length and BMR of mammals.

Using Quaardvark to dig into specific species' averages of each component.

Organisms used: mammals, birds

Type of experiment: Theoretical

Background

Unknown/Problem

Question and Hypothesis

Approach

BMR is something all organisms need to utilize their energy. This is the measure of metabolism when the organism is not exercising or exerting too much energy,

Much like we burn calories while sitting and sleeping, the same goes for other organisms.

Previous research doesn't answer whether body length could have anything to do with BMR.

While body mass may have a relationship with BMR, does body length? Body mass and length aren't always related.

Research the species given in the Quaardvark database and see how the factors work out to show a relationship in both areas of questioning.

Is there a relationship between body length and BMR for mammals specifically? What about body mass and BMR in both mammals and birds?

The greater the body mass is, the greater the BMR is. The greater the body length, the greater the BMR is.

The more body mass an organism contains, the more it can metabolize. The longer an organism is usually indicates more surface area to contain more mass in, also leading to a greated BMR.

Design

Independent Variable: Body mass of each species, body length of each species tested

Dependent Variable: BMR rates

Subjects

Experiment groups: Mammals, birds

Averages of each species listed are used as the data points.

Procedure

Using the Quaardvark database and selecting specific physical qualities such as body mass, body length, and BMR. Assemble into charts according to hypothesis question.

Paragraphs

Gain an understanding of just how important BMR can be and how it may be useful to understand the other components that may effect or be affected by such a factor.

Figures

Add in tables that came from Synopsis 5? Captions above tables, still explain in paragraphs what we're looking at and how it supports the hypotheses.

1st paragraph, main findings

What does this relationship mean for mammals and birds? How are their lives changed by having determined BMRs?

Middle paragraphs, other findings

Limitations of experiment: Species not included in the database, outliers that may not have the same representation, animal members that may be an outlier to the averages of their species' factors, species that may have different physical factors based on geographical locations.

Reiterate tying the tables in to support both hypotheses. BMR has a positive relationship with both body mass and length.

Last paragraph

Tying all of the hypotheses together. BMR is something that we as humans experience and has a giant impact on day to day life. Exerting energy is part of daily functions, without proper storage of energy, there could be negative consequences.
