"apps where the students are still presenters but do so digitally. This means they can share the presentation, embed it in the digital portfolio and even let mum and dad see their work. Some of these even allow you to create an avatar or use a photo and then import it into the app to have your students present as themselves."

"The Palauan jellyfish, Mastigias. The researchers placed green fluorescent dye upstream of the animal body. As the animal continued to swim, it interacted with the dye volume and pulled a volume of dye along with it. This volume of fluid moving with the animal is drift (first identified by Sir Charles Darwin, the grandson of the Origin of Species author)."

"Check out our fun flight facts for kids and learn how planes fly as well as interesting information about aviation history, the Wright Brothers, animals that fly and much more."

"The four-stroke cycle (or Otto cycle) of an internal combustion engine is the cycle most commonly used for automotive and industrial purposes today (cars and trucks, generators, etc). It was conceptualized by the French engineer, Alphonse Beau de Rochas in 1862, and independently, by the German engineer Nikolaus Otto [[1]] in 1876."

"Best known for his "inventions", Rube's early years as an engineer informed his most acclaimed work. A Rube Goldberg contraption - an elaborate set of arms, wheels, gears, handles, cups and rods, put in motion by balls, canary cages, pails, boots, bathtubs, paddles and live animals - takes a simple task and makes it extraordinarily complicated. He had solutions for How To Get The Cotton Out Of An Aspirin Bottle, imagined a Self-Operating Napkin, and created a Simple Alarm Clock - to name just a few of his hilariously depicted drawings. "

"The order that animals feed on other plants and animals is called a food chain. Do you think you can put a food chain together? give it a try and learn why every animal within a food chain is so important."

"An elephant's hairs help heat travel away from the skin. According to the study, a light breeze is enough to significantly cool an elephant, increasing its heat loss by 20 per cent. Elephants, big leathery animals that they are, need to know how to cool off. They also use their trunks to splash water and mud on themselves."

"the study of linear algebra, the theory and practice of analyzing linear relations and their behavior under linear transformations. Practically every modern technology relies on linear algebra: simplifying the computations required for internet searches, 3-D animation, coordination of safety systems, financial trading, air traffic control, and everything in between. Five major topics are addressed: linear systems of equations, vector spaces, matrices and linear transformations, determinants, similarity, and eigenvalues. This free course may be completed online at any time."
