Today we're going to begin our three-part unit on p-values. In this episode we'll talk about Null Hypothesis Significance Testing (or NHST) which is a framework for comparing two sets of information. In NHST we assume that there is no difference between the two things we are observing and and use our p-value as a predetermined cutoff for if something seems sufficiently rare or not to allow us to reject that these two observations are the same. This p-value tells us if something is statistically significant, but as you'll see that doesn't necessarily mean the information is significant or meaningful to you.

Why is seawater salty?
Hello Happy Friends!
Are you ready to learn?
I’m Sarah, and today, I want to solve a question I’m always asking myself… and I’m sure that you’ve asked yourselves about it too!
Have you ever wondered, why seawater is salty?
Oceans and seas, were formed thousands of years ago
because of rainwater
But…
Why is seawater salty, if rainwater and volcano vapour don’t taste to anything?
They are, insipid!
That’s because rivers, reach the sea,
and these rivers contain mixed mineral salts dissolved in their waters.
As you already know, though the water cycle, water from the sea is evaporated because of the sun’s heat.
But not all the mineral salts that come from rivers are evaporated,
so they are accumulated in large amounts within the sea’s waters.
This is the reason why marine water, sea water has such an intense taste.
Seawater isn’t pure water, it’s a mix.
It’s a dissolution of water and mineral salts.
So that means it’s not safe to drink, it’s not drinking water.
The sea, is crucial for our planet.
That’s why we need to take care of it. It’s home to many amazing animals, like these!
And it lets us do really cool things like…
play with our friends sonreír surf
or enjoy a sailboat ride at sunset.
Goodbye happy friends!
I hope you’re always ready to learn!
Goodbye!

Fun facts about animals

The secret behind a cat’s tongue

Cats are very special mammal animals, and until not long ago, they had a secret in their tongue which we have finally discovered. They are very sleepy animals, they sleep 14 hours a day, but they are also very clean, since when they are awake they dedicate a long time to cleaning their bodies with their own tongues.

But we couldn’t understand how they could clean themselves perfectly by just licking. Some researchers have found out that cats tongues are covered in many tiny thorns called buds. These thorns have a hollow cavity, which cats use to fill with saliva and use it, as if it was a sponge with water and soap, to clean all of their bodies. That is, by licking themselves! Cats are very clean, and beautiful!

Students use the engineering design process to solve a real-world problem—shoe engineering! Working in small teams, they design, build and test a pair of wearable platform or high-heeled shoes, taking into consideration the stress and strain forces that it will encounter from the shoe wearer. They conclude the activity with a "walk-off" to test the shoe designs and discuss the design process.

Students investigate the idea of linear approximation. Students apply mathematical modeling, specifically linear approximation, to an already collected data set to make a prediction. In this lesson, students first engage in a warm-up that is not a perfectly linear data set, being exposed to this for the first time. Students take on the role as a packaging engineer to learn the process to apply linear approximation modeling: collecting data, creating a graph, drawing a line-of-fit, creating a model in the form of an equation, defining the model’s variables, and evaluating with the model. Students ultimately use their linear model to predict the net weight of cereal in grams contained by 260 square inches of cardboard packaging.
