MUTO a wall-painted animation by BLU

Some of you wanted to be animators. Well, here is an example of something you can start playing with that will teach you some skills.
You want to become the best?

Keep on practicing!

Another small artist

You want to be an artist?

Start practicing, there is plenty of options: sculpture, painting, dance, music...

Marla Olmstead: Small artist

The earlier you start learning what you want to do, the easier it gets to be really good at it.
It could be your first job!

Who studies space?

The Milky way. Can you find the our Sun?

Future Animals

Who studies the animals of the future?

Singing Tesla Coil - MIDI Controlled

Any ideas about how does it work?


Remember what is the job of an engineer?

Well, guess who is in charge of building and fixing these robots!

(Engineers fix and build things, for example: robots, bridges, cars, etc. Engineers usually go to school for at least 6 years, but you see, once you find what you like, you will never stop learning about it!!!)

Aphids: Plant vampires?

Here are some pictures of aphids, like the ones we saw in the school garden plants.
Aphids are many times plant pests. What is a pest?
Ask in class.


Aphids can have several colors. They can be green, red, black, white, etc. What color are the aphids we saw last time?

Ladybugs eat aphids. They are able to track them down and hunt them. Here is a picture of a ladybug eating one of them.

More Adaptations

Remember, an adaptation is any change that brings an advantage.
For example, you can randomly pick a new pair of tires for your bicycle, OR you can adapt it to a mountain environment. Then, what kind of tires would you pick?

Now, let's look at these structures, they look very alike, right? Why is that?
Count how many bones are there?
It is the same number, isn't it? Only the shape and disposition of the bones has changed.
Such changes, despite being random, bring at least one advantage to the animals that carry them.
For example, if you lived in the ocean would you need legs?
Compare the bones of the whale "arm" with those of the rest of animals in this graph.

Although they are organized in a basic and very similar way, they are not identical.

What looks like the best limb if you want to run?
What about flying??

When animal structures look very alike but they are not quite the same, these structures are referred as homologies.

Homologous structures are structures that have a similar origin (they come from very similar processes), but still are not quite the same. Evolution refers to the adaptations in these structures and how they bring certain advantages to the animals that change.

Look how the babies of different animals develop. Do you think they look quite similar during their very early ages?

Now, try to draw these bone structures.

The bat skeleton


An adaptation is any change that brings an advantage to the plant or animal.
Remember, changes can be generated randomly (without control), but an adaptation must make things better for the plant or for the animal that is changing.

Check the adaptations of these animals. They live in a desert environment.
What is the environment?
What do you think these animals will need to survive under such extreme conditions?

Human Evolution

The image “http://hydrodictyon.eeb.uconn.edu/courses/EEB210/evolution.jpg” cannot be displayed, because it contains errors.

One of the theories about the origin of our species refers to the constant adaptation of our bodies and minds to and ever-changing environments.

Where do humans come from?

Is it minerals?
The Earth?

Now we go to the store an buy stuff; for that we need money or a credit card. We need a job if we want to make that money.
Money makes consumption possible and currently drives the economy of the United States.
You buy what you want, but do you need what you buy?


Once products are manufactured at factories, these products must be distributed to the stores where you can find them.
Products move between factories and stores through trains, trucks and ships. Imagine all the gas that is used to move these things around.

From the factories to the ship:


From the ship to the train.


From the train to the truck.


And from the truck to the store.

Have you seen any of these happening around you?


Robots working on a car. How many people can you see in this video?

Production: Work must me done by people or machines

To make the stuff we use work must be done by people or machines.

Production: "Made in China"

An important ingredient when fabricating the stuff we use everyday is work. Work must be done by people or machines.

Map of the world: Where does stuff come from?


Try to find in this map:
Where was the class VCR made at?
Where were your shoes made at?
Which countries have we been hearing about in class and through our class videos?

Extraction: The consequences of mining

Minerals like gold, silver, diamonds, oil, aluminium, steel, platinum, etc. come from mines. Extracting these minerals from the mines can be very polluting. Remember pollution means poison.
Mines can contribute with water and air pollution.

Extraction Limitations

Forests not only provide with wood. They are home to people and many different species of animals, when forests are gone, so are the many different living communities they house.
What kind of animals live in trees?

Monkeys, squirrels, ants, bats, etc, etc, etc.

Trees also provide us with shade and weather stabilization. Trees prevent erosion too.
Erosion is the lost of fertile or productive soil.

Extraction limits deforestation


How long does a tree take to grow?
How long do we take to cut it down?
What is the problem here?

The living forest

Remember: Where do plants get their energy from?


Reforestation: When trees are gone we lose not only the oxygen they provide us with, but also all other services.
Trees provide us with shadow, weather stabilization, and they are also home for birds, monkeys, bats, ants, etc.
