Pre-order our book YOU ARE AN ARTIST (which includes new assignments!) here: http://bit.ly/2kplj2h

This week we visit Lenka Clayton, another Pittsburgh based artist whose work finds meaning in ordinary, everyday objects. For her assignment, she asks you to partner with someone and recreate a lost childhood object, using their memory of the object and the materials you have around you.

INSTRUCTIONS - Lost Childhood Object
1. Ask someone to describe an object they made or cherished as a child. Make a mental image of that object
2. Create the object
3. Give the object back to the person (Ideally, you'd do this project in tandem)
4. Document and upload using #theartassignment
5. Fame and glory (your work might be in a future episode)

Sarah then connects this assignment to contemporary artist Roman Ondak.

"Shawna's 3D Shapes" (See below for lyrics)

Your child will enjoy singing along to "Shawna's 3D Shapes" as Shawna sings about six three-dimensional shapes (the sphere, cube, rectangular prism, cone, cylinder, and pyramid) and points out common objects in which these shapes can be seen.

Song Lyrics:

Let’s sing about three-dimensional shapes.
No two look the same.
We see these six shapes everywhere.
Let’s learn them all by name.

Let’s start with spheres,
like the Earth and the moon
And the sun in our sky of blue.
Balls are spheres that are lots of fun—
Oranges and marbles are, too.

There are six sides on each cube you find,
And each side is a square.
Sugar and blocks can be shaped like cubes,
Like the ice cubes in your glass... there!
Let’s sing about three-dimensional shapes.
No two look the same.
We see these six shapes everywhere.
Let’s learn them all by name.

Rectangular prisms have six sides.
I can think of quite a few,
Like a shoe box, a train car,
a long stick of butter,
A brick, and a suitcase, too.
With a circle on the bottom
and a point at the top,
A cone is a shape you’ll see.
Party hats and teepees are shaped like cones,
And so is a green pine tree!

Let’s sing about three-dimensional shapes.
No two look the same.
We see these six shapes everywhere.
Let’s learn them all by name.

Cylinders have circles at each end,
Like a soup can or paper towel roll.
Drinking straws and glasses have cylinder shapes,
And so does our school flagpole
What shape has three or more triangular sides
And a point at the top? Can you guess?
The base can be a square, or a different shape.
Say, “A pyramid” and I’ll say, “Yes!”
Let’s sing about three-dimensional shapes.
No two look the same.
We see these six shapes everywhere.
Now you know them all by name!

Is there a border we will never cross? Are there places we will never be able to reach, no matter what? It turns out there are. Far, far more than you might have thought…

The Brain Eating Amoeba
A war has been going on for billions of years that breeds well armed monsters who struggle with other monsters for survival. Having no particular interest in us, most of them are relatively harmless, as our immune systems deal with their weapons handily. But there are exceptions.
Naegleria fowleri is an amoeba that not only has developed a deadly taste for human brains but is also a match for our defenses and a guest in dramatic headlines. What happens when this monster enters your body?

Our home is burning. Rapid climate change is destabilizing our world. It seems our emissions will not fall quickly enough to avoid runaway warming and we may soon hit tipping points that will lead to the collapse of ecosystems and our civilization.

While scientists, activists and much of the younger generation urge action, it appears most politicians are not committed to do anything meaningful while the fossil fuel industry still works actively against change. It seems humanity can’t overcome its greed and obsession with short term profit and personal gain to save itself.

And so for many the future looks grim and hopeless. Young people feel particularly anxious and depressed. Instead of looking ahead to a lifetime of opportunity they wonder if they will even have a future or if they should bring kids into this world. It’s an age of doom and hopelessness and giving up seems the only sensible thing to do.

But that’s not true. You are not doomed. Humanity is not doomed.

Vaping is marketed as the “safe” alternative to smoking, but it’s far from being harmless. Unregulated ingredients, hidden toxins, and extreme nicotine levels mean we’re conducting
a massive experiment on ourselves. Let’s dive into what we know – and what we don’t know, yet.

A nuclear bomb is the most devastating explosion ever created.
One bomb can end tens of thousands of lives immediately and
hundreds of thousands through the radioactive aftermath. However,
the worst part comes afterward: a nuclear winter that might kill billions,
potentially leading to the complete collapse of our civilization.

In a nuclear winter, there are no winners – only starving losers.
How exactly does it work and what would it look like?

Over the last decade milk has become a bit controversial. Some people say it’s a necessary and nutritious food, vital for healthy bones, but others say it can cause cancer and lead to an early death.

So who is right? And why are we drinking it anyway?

Black holes can destroy everything – but can they be destroyed? What happens if we push physics to the absolute limits, maybe even break it and the universe in the process? Let’s create a tiny black hole, about the mass of our moon, in the Kurzgesagt Labs and try to rip it apart.

Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: https://simplisafe.com/veritasium

I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:
https://www.compliantmechanisms.byu.edu

At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.

What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:

1. Part count (reduced by having flexible parts instead of springs, hinges)
2. Productions processes (many, new, different enabled by compliant designs)
3. Price (reduced by fewer parts and different production processes)
4. Precise Motion (no backlash, less wear, friction)
5. Performance (no outgassing, doesn't require lubricant)
6. Proportions (reduced through different production processes)
7. Portability (lightweight due to simpler, reduced part count designs)
8. Predictability (devices are reliable over a long period of time)

Animation by Alan Chamberlain

If you spin a raw egg and then stop it, it will start spinning again without you having to touch it. A boiled egg, on the other hand, stops and stays stopped. Why is this? Well a raw egg contains a yolk that moves inside the egg independently of the shell. If you stop the shell, the yolk inside continues to move due to its inertia and it therefore gets the egg spinning again.

A song about Gravity set to the tune of John Mayer's Gravity.

Gravity is working with me
And Gravity, keeps me on the ground

All mass attracts all other mass
a force proportional to mass one and two
and inversely to the distance between them squared

Oh, gravity is working with me
and gravity, makes apples fall to ground

Oh twice the mass has twice the pull
but the force on each is still equal
It keeps the moon and the satellites
going round

Oh twice the mass has twice the pull
but the force on each is still equal
It keeps the moon and the satellites
going round

Oh gravity, the force that makes weight on me
Woah, gravity, now general relativity (how can that be?)

The force between us all is
The force between us all is
The force between us all is
Gravity between us all is
Gravity between us all is
Gravity between gravity between us all is
