This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—a unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an important concept in the engineering design process. Students create graphite-based fibers using sodium alginate as the medium and a calcium coagulation bath, which is similar to the way in which graphene-based fibers are created in engineering research laboratories. Students then determine the factors that contribute to resistivity and vary these parameters to optimize fiber resistivity.

Music: Bella Bella Beat - Nana Kwabena
Students learn about civil engineers and work through each step of the engineering design process in two mini-activities that prepare them for a culminating challenge to design and build the tallest straw tower possible, given limited time and resources. First they examine the profiles of the tallest 20 towers in the world. Then in the first mini-activity (one-straw tall tower), student pairs each design a way to keep one straw upright with the least amount of tape and fewest additional straws. In the second mini-activity (no "fishing pole"), the pairs determine the most number of straws possible to construct a vertical straw tower before it bends at 45 degrees—resembling a fishing pole shape. Students learn that the taller a structure, the more tendency it has to topple over. In the culminating challenge (tallest straw tower), student pairs apply what they have learned and follow the steps of the engineering design process to create the tallest possible model tower within time, material and building constraints, mirroring the real-world engineering experience of designing solutions within constraints. Three worksheets are provided, for each of two levels, grades K-2 and grades 3-5. The activity scales up to school-wide, district or regional competition scale.

What are you waiting for? 💭Do you know how and why there are different seasons in a year?
Learning with Sarah, you'll find this out and much more by learning with Sarah...

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!

Did you know that the biggest shark that has ever existed was the megalodon?
This gigantic beast had a length of 20 meters and weighed 20 tones! The megalodon lived nearly 20 million years ago and disappeared 2 million years ago. It is considered as one of the most powerful predators of history of the vertebrates and their favorite prey where sea mammals such as whales or dolphins. It is a shame that the megalodon has disappeared but to be honest, it would have been really scary. By the way, did you know that its name originated from Latin and it means ‘Big tooth’?
Did you know that sharks can have thousandths and thousandths of teeth in their life time?
Sharks have their denture distributed in layers. when a tooth breaks, immediately, it is replaced by the layers above.
In general sharks have between 5 and 15 lines of teeth, although the first line is the most important, and it is what they usually eat their prey with. Many scientists have assured us that sharks can have up to 30 million teeth during their life
Did you know that sharks don’t stop swimming, not even for when they need to sleep?
This is because of wo reasons. The first is because of their breathing. Whilst sharks swim, they maintain their mouth open, this way the water that contains a lot of oxygen, passes through their gills and absorbs the oxygen to be able to breath. The second reason is that, differently from all fish, sharks don’t have a swim bladder a kind of internal float that fills with air and allows them to float even though they are still. It sounds weird but it is true, if a shark stops swimming it will fall to the bottom of the ocean and drown. Although the sleeping fish is eaten by the shark…..
