**Big as a Whale.**

Blue Whale

Length in Meters: 3.0 x 10¹

Weight in Kilograms: 1.6 x 10⁵

Girth in Centimeters: 1.4 x 10³

Daily Food Consumption

in Kilograms: 4.0 x 10³

fun fact- their tongue can weigh as much as an elephant.

Humpback Whale

Length in Meters: 1.6 x 10¹

Weight in Kilograms: 3.6 x 10⁴

Girth in Centimeters: 1.219 x 10³

Daily Food Consumption

in Kilograms: 1.36 x 10³

fun fact- they sing, and their songs are complex with each population singing its own unique song.

Gray Whale

Length in Meters: 1.5 x 10¹

Weight in Kilograms: 3.5 x 10⁴

Girth in Centimeters: 9.15 x 10²

Daily Food Consumption

in Kilograms: 1.2 x 10³

fun fact- most gray whales are born around mid January and are born at an average of length of 12 – 14 feet long at birth.

Orca Whale

Length in Meters: 9.7 x 10⁰

Weight in Kilograms: 5.44 x 10³

Girth in Centimeters: 5.5 x 10²

Daily Food Consumption

in Kilograms: 2.3 x 10²

fun fact- each pod has its own dialect of calls (that only they use).

Right Whale

Length in Meters: 1.525 x 10¹

Weight in Kilograms: 6.36 x 10⁴

Girth in Centimeters: 9.15 x 10²

Daily Food Consumption

in Kilograms: 1.36 x 10³

fun fact- they were named by whalers who identified them as the "right" whale to kill on a hunt.

How many times longer is a blue whale than krill?

One krill is approximately 15 mm in length, so to figure it out, you would have to do 30 m by 1000 mm, getting 30,000. Then you would divide that by 15, getting 2,000.

So a blue whale is 2,000 times larger than a krill.

How much will each whale consume in one year?

y = 365 x DFC.

Blue Whale

365 x (4.0 x 10³) = 1.46 x (10⁶)

A blue whale consumes 1,460,000 Kg of food each year.

Right Whale

Orca Whale

Humpback Whale

Gray Whale

Which whale fits in our classroom?

Hugging a Whale

We hope you had a WHALEy good time going through this presentation.

Students Needed to Hug Each Whale

Blue Whale

Girth (cm) 1400

Students y=1400/166= 8.43= 9 Students

Humpack

Girth (cm) 1219

Students y=1219/166= 7.34= 8 students

Right Whale

Girth (cm) 915

Students Y= 915/166= 3.51= 4 students

Gray Whale

Orca Whale

Girth(cm) 550

Students y= 550/166= 3.31= 4 students

Girth (cm) 750

Students y= 750/166= 4.52= 5 students

They eat krill and copepods.

classroom dimensions-

length- 8.9115 meters

width- 8.9115 meters

height- 2.742 meters

diagonal- 12.6 meters

Only the Orca fits, and only diagonally because the diagonal length of the room is 12.6 meters, and the Orca is approximately 9.7 meters.

a^2+b^2=c^2.

8.9115^2 + 8.9115^2 = 12.6^2

365 x (1.36 x 10³) = 4.964 x 10⁵

A humpback whale consumes about 496,400 kg of food each year.

How to find mean.

Looking at the graph, to hug a whale with a girth of 8 m, it would take about 5 people.

The mean of the classroom arm spans, is 166 cm.

To find how many students it would take to hug a whale, you would use the equation y=x/166, with x being the girth of the whale.

Arm span of the class in centimeters

To find mean, add all, making
