Here is a quick example of using the Makey Makey / micro:bit power-glove to create a Scratch writing project for kids. Students will create monster mashups in Scratch that they can control with a DIY crafted power-glove.

A simple test to see if a number is prime or composite. All you do is find the square root of the number. Next, find all the prime numbers of this number. If none of these prime numbers are a factor of the number then the number is prime.

A spider looks like an insect, but a spider is not considered an insect.
A spider is an arachnid and is similar to an insect but also different.
Spiders have two body regions, eight legs, no wings or antennae compared to insects.
Are spiders bugs? No, but they have several similar characteristics

Excretory system
The excretory system removes waste and toxins from the human body.
Your skin eliminates waste by sweating.
Your lungs eliminate carbon dioxide.
Your kidneys filter over 180 liters of blood in order to produce urine.
The kidneys filter waste like urea. This liquid that is collected is called urine.
Your kidneys are made up of millions of filtering units called nephrons.

Cenozoic EraIn this video I would like to talk about the Cenozoic era on the geologic time scale.
The Cenozoic era is the most recent era and is part of the Phanerozoic Eon along with the Paleozoic and Mesozoic eras.
The Cenozoic era lasted roughly 65 million years.
The Cenozoic era is most often described as the “ age of mammals” but could also be called the
“Age of flowering plants” or the age of insects.
Let’s hit several highlights of this era
Although the first mammals appear in the Mesozoic era they begin to thrive during the Cenozoic era and spread throughout the world.
Birds become more diverse and becoming more diverse.
In addition flowering plants also begin to thrive and spread to all corners of the Earth
Along with insects.
Apes and Humans also appear
During this era, the Earth is cooler and ice ages occur and the formation of glaciers.
In addition, the continents have moved into their modern location and several mountain ranges including the Alps, Himalayas, and the Rocky mountains

In this video, I use diffusion cubes to show why cells are so small. A small cell with a large surface area to volume ratio can efficiently move materials into the cell.

Diffusion is a type of passive transport that cells use in order to move materials like oxygen and carbon dioxide into and out of the cell.
A cell with a larger surface area to volume ratio is more efficient a moving material than a cell with a smaller ratio.

Here is my recipe for the diffusion blocks
gelatin
Ammonia
Phenolphthalein
If you soak the diffusion cubes in vinegar then the phenolphthalein will turn pink when it comes in contact with the vinegar which allows you to see the rate of diffusion.
