Science 5: Drawing Conclusions
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.

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]
Okay, now that's just plain awesome.
Know what else is fun to draw?
No, we won't actually be drawing anything...but stick with us here.
We mean the other type of drawing, as in, to formulate. [Scientists looking happy]
And it's something that scientists do all the time.
Once they've finished an experiment, scientists must look at all of their data, aka all those
fun facts and statistics they collected, and draw conclusions about what it all means.
Say we conducted an experiment where we grew pea plants in pots containing different sorts [Plants growing]
of soil: sandy soil, potting soil, and clay soil.
If, after watching over them carefully and singing them lullabies, the plant in the potting [Scientist singing]
soil grew the tallest, we could conclude that the potting soil provides the best nutrients
for the plant. [Scientist looking happy]
Then we can even draw a diagram of our data and conclusions afterwards. [Scientist drawing a graph]
It's a great way to display our results, and let's be real, it's kind of fun.
But uh…leave the army of monsters off of this drawing… [Monster rubs out some of the graph]
Now, what if we grew our pea plants using different amounts of water? [Guy pouring a watering can on the plants]
If we drew up a graph of the data and it showed us a bell curve, then we could conclude that
pea plants have an optimal amount of water that they need to grow. [Picture of a bell curve]
Too little water or too much water and they won't grow well. [The plant in the middle grows quickly]
So far, we've covered the type of soil and the amount of water – but what if we experimented [Teacher pointing at a blackboard]
with the amount of light?
Light, after all, is the most important element of photosynthesis, but can a pea plant, much [Plant sat on a deckchair]
like a lobstery tourist on the beach, get too much sun? [The plant's sunglasses fall off and it looks dead]
Well, if we conducted a similar experiment to our water study, but this time, we varied
the amount of light exposure, and the graph ended up also looking like a bell curve, then
we would similarly conclude that pea plants have an optimal amount of light as well.
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]
What we've done here are several examples of drawing conclusions.
By conducting an experiment and analyzing the data we gathered, we're able to draw conclusions
about what that data means.
Because really, data is just a bunch of numbers and graphs.
It's up to us to turn the data into something meaningful that we can understand and teach [Teacher looking confused]
Now we hope you like peas, because we sure have a lot of them!
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]
Sounds delicious, right?
Alright…guess we'll just drink this pea shake all by ourselves… [The chef starts drinking the pea shake]
