Students collect data and apply mathematical modeling, specifically linear approximation, to predict what will happen in a specific situation. In this activity, students collect data to determine the number of Jelly Belly jelly beans it takes to fill up the respective tube. Students plot their data, graph a linear approximation model, and write an equation representing their model. Students use their linear model to predict the number of Jelly Belly jelly beans that are in a similar cylindrical tube with a given height. Students discuss the accuracy of their results and limitations in their model and data collection process. They then apply their predictions to make suggestions to Jelly Belly for potential packaging of jelly beans based on quantity instead of net weight.

Students play the role of engineers as they test, design and build Mentos® fountains—a dramatic example of how potential energy (stored energy) can be converted to kinetic energy (motion). They are challenged to work together as a class to optimize the design of the basic soda/candy geyser made by the teacher. To do this, three research teams each investigate how a different variable—nozzle shape, soda temperature, number of candies—affects fountain height. They devise and run experimental tests to determine the best variable values. Then they combine their results to design the highest fountain to compete head-to-head with the teacher's geyser design.

Hello Happy friends!
Are you ready to learn?
I’m Sarah, and Today, we’re going to learn a little more about the seasons, and to do this, we’re going to learn about the hemispheres.
-
We all know, that there are four seasons in a year, spring, summer, autumn and winter. And that each one of them has different weather conditions.
-
In winter, it’s very cold
In spring, temperatures start to rise, and of course, flowers start to blossom.
In summer, it’s usually extremely hot
And, in autumn, temperatures start to decrease, and leaves start falling from trees.
-
But… Did you know that the seasons don’t happen at the same time all over the world?
Nope! they don’t, so let’s find out why!
-
Planet Earth, has an axis, an imaginary line, where the earth spins around itself, in a rotational movement.
-
This axis is not up straight, it’s actually leaning, and depending on the month of the year, there are areas that receive more heat than others.
-
Our planet is also divided into two parts, separated by an imaginary line called equator.
This line, divides the earth into two hemispheres: the Northern Hemisphere, and the Southern Hemisphere.
-
Now, let’s see how our planet moves around the sun.
It’s what we call a translation movement.
-
As you can see, the sun heats the Earth, but not equally around the whole world.
Let’s stop the planet. Stop!
In this position, the northern hemisphere has more sun rays, because of the axis inclination.
And that means… We’re in summer! And meanwhile, in the southern hemisphere it’s winter.
buff I prefer summer!
-
But, what happens if the Earth rotates on the other side of the sun?
Well, there would be more rays in the southern hemisphere, meaning that in the northern hemisphere, it’s winter, and in the southern hemisphere, it’s summer.
Easy peasy huh?
Goodbye happy friends! See you next time!
I hope you’re always ready to learn!
Goodbye!

Hello Happy friends! Welcome to a new Happy Learning Video!
Plants, like all living things need to reproduce to perpetuate their species, to survive though time.
They can have a sexual or asexual reproduction. Today, we’re going to get to know plant asexual reproduction.
In asexual plant reproduction, flowers don’t intervene, there’s no need for a gamete or female and male cell. In asexual reproduction, there’s only one parent, so the new plants will be genetically identical to this. New plants can originate from a single cell, a tissue, an organ or a part of a mother plant.
There are two types of asexual reproduction: vegetative reproduction and reproduction without seeds. Let’s get to know them.
Vegetative reproduction is when new plants are formed from a part of a mother plant, generally from the tip of the stem. This type of reproduction is used a lot in agriculture and gardening. There are four types: root vegetables, bulbs, stolons and rhizomes.
Root vegetables, are underground stems which store lots of nutrients, lots of nutritive substances. Examples include potatoes or sweet potatoes. As you can see in the images, a new plant can come from each potato.
Bulbs, are also underground stems but formed by fleshy leaves which store nutrients. Onions, garlics and tulips reproduce through bulbs.
Stolons, are stems which grow horizontally parallel to the floor. When they come into contact with the floor, they form roots and a new plant is born. Strawberries and mint are examples of stolons.
Rhizomes are the same stems as stolons, but underground and new plants are formed from them. Rhizomes grow indefinitely, so they can cover a wide surface. Lots of types of grass, reeds and trees like populus and oaks are examples of rhizomes.
Plant reproduction without seeds is present in mosses and ferns. These plants combine sexual and asexual reproduction. When the female and male gamete meet, structures are formed called spores. These spores, once they are developed and mature, are then impulsed by wind until they fall on the floor and germinate, then new plants are born.
The truth is that nature is wonderful, it’s incredible Did you know, that the oldest ferns are older than the dinosaurs? They have been reproducing on earth for over 420 million years! It’s incredible!

Today we are going to learn about a very special form of relationship between species: symbiosis!
Normally when people talk about "symbiosis", they're talking about two or more different organisms cooperating to better survive and reproduce. The classical definition of symbiosis is actually much broader than this, and for good reason. Here we will look how evolutionary biologists understand symbiosis, all its different forms, and why it matters!

Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to learn about of the first and most important of human civilisations, today, we’re going to learn about… Mesopotamia!
The word Mesopotamia means “between two rivers” in greek! So this civilisation was named because it was situated between two rivers: Tigris and Euphrates.
Within these fertile lands, the first ever city-states were born, four thousand years before Christ! The most important cities were Ur, Urk and Lagash.
These city-states were independent from each other, like small different countries.They were surrounded by a great wall to protect themselves. The Ziggurat, a temple where priests lived, was built in the center of the city. Here, they controlled the trade, agriculture and taxes. The supreme priest had the city's political and religious power
Agricultural fields spread across these cities, which were traversed by irrigation channels that used the river’s water to water cultivations and animals would drink. Most of the city’s citizens were farmers and shepherds, but there were also artesans that sold their own products at the markets.
Because of their well-being, both cities began to grow, but so did the conflicts between them due to the control of land.
These battles arose military leaders that little by little turned into monarchs, Kings!
Between the years three thousand a one thousand B.C., Mesopotamian lands were conquered by various towns or cities. The first one was the Akkadian Empire, then the Babylonian Empire, followed by the Assyrian Empire and finally the Persian Empire.
So we’ve got to know part of Mesopotamia’s history, but do you know why it has been such an important civilisation for humanity?
Well there are many reasons! The first one is, because Mesopotamia was where, around 3500 B.C., the first written language was found. At first, it was composed by simple drawings called pictograms, look at these examples.
Over time, these drawings were simplified and started to transform into symbols, which is what we know today as cuneiform (cuniform) writing. As you can see, this writing was made with a wooden punch over clay boards.
Another great contribution mesopotamia made was its art. They created the arc and vault, that helped them construct magnificent temples and palaces. To decorate the walls and doors within these temples and palaces they used paintings like this one, where the King Ashurbanipal is hunting lions.
By the way, before we say goodbye, Do you know what country Mesopotamia is today?
Well it’s… Irak! you can see it here.
