Description:

Today we'll be drawing conclusions. And since this is a science video, you can probably conclude that we will not be drawing pictures. Yep, it's the other kind of drawing...sorry to get your hopes up.

[Dino and Coop singing]

00:12

There are tons of things that are fun to draw...

00:15

A picture of your dog...

00:16

A picture of your little sister... [Kid drawing]

00:18

A picture of your little sister that actually looks like your little sister.... [Boy laughing]

00:22

Or even a picture of your little sister and your dog fighting off an army of monsters. [Picture comes to life and boy looks shocked]

00:25

Okay, now that's just plain awesome.

00:28

Know what else is fun to draw?

00:29

Conclusions!

00:30

No, we won't actually be drawing anything...but stick with us here.

00:34

We mean the other type of drawing, as in, to formulate. [Scientists looking happy]

00:36

And it's something that scientists do all the time.

00:39

Once they've finished an experiment, scientists must look at all of their data, aka all those

00:43

fun facts and statistics they collected, and draw conclusions about what it all means.

00:48

Say we conducted an experiment where we grew pea plants in pots containing different sorts [Plants growing]

00:52

of soil: sandy soil, potting soil, and clay soil.

00:56

If, after watching over them carefully and singing them lullabies, the plant in the potting [Scientist singing]

01:00

soil grew the tallest, we could conclude that the potting soil provides the best nutrients

01:04

for the plant. [Scientist looking happy]

01:06

Then we can even draw a diagram of our data and conclusions afterwards. [Scientist drawing a graph]

01:09

It's a great way to display our results, and let's be real, it's kind of fun.

01:14

But uh…leave the army of monsters off of this drawing… [Monster rubs out some of the graph]

01:16

Now, what if we grew our pea plants using different amounts of water? [Guy pouring a watering can on the plants]

01:20

If we drew up a graph of the data and it showed us a bell curve, then we could conclude that

01:24

pea plants have an optimal amount of water that they need to grow. [Picture of a bell curve]

01:27

Too little water or too much water and they won't grow well. [The plant in the middle grows quickly]

01:30

Alrighty.

01:31

So far, we've covered the type of soil and the amount of water – but what if we experimented [Teacher pointing at a blackboard]

01:35

with the amount of light?

01:37

Light, after all, is the most important element of photosynthesis, but can a pea plant, much [Plant sat on a deckchair]

01:41

like a lobstery tourist on the beach, get too much sun? [The plant's sunglasses fall off and it looks dead]

01:45

Well, if we conducted a similar experiment to our water study, but this time, we varied

01:48

the amount of light exposure, and the graph ended up also looking like a bell curve, then

01:53

we would similarly conclude that pea plants have an optimal amount of light as well.

01:57

We can also conclude that our bell drawing skills are off the charts, just look at that thing! [Shiny stars come off the bell curve]

02:02

What we've done here are several examples of drawing conclusions.

02:06

By conducting an experiment and analyzing the data we gathered, we're able to draw conclusions

02:10

about what that data means.

02:12

Because really, data is just a bunch of numbers and graphs.

02:15

It's up to us to turn the data into something meaningful that we can understand and teach [Teacher looking confused]

02:19

to others.

02:20

Now we hope you like peas, because we sure have a lot of them!

02:23

We've made boiled peas, mashed pea, pea soup, pea stew, pea cake, pea pie and even a pea [Chef next to all the pea dishes]

02:27

milk shake.

02:29

Sounds delicious, right?

02:30

Anyone?

02:31

Any takers?

02:32

Alright…guess we'll just drink this pea shake all by ourselves… [The chef starts drinking the pea shake]
