You are constantly surrounded by media, so the question is: how does your brain handle all of that? The unfortunate answer is that our brains have a lot of processes that not super helpful for media literacy, but hopefully with a little self-awareness, we can work around that.

We join Jay, a medical emergency helicopter pilot, as he tells about what he does in his job on the day to day, and the physics and math involved in piloting a helicopter. It’s an exciting job that has the added benefit of saving lives and doing good in the world.
ABOUT THE SCIENCE
If you are deciding between getting your own plane or helicopter, you should keep in mind that a helicopter has two main advantages over a fixed-wing aircraft. Helicopters can take off and land vertically, which means you could land it in your backyard, and they can change direction easily.The helicopter is the most versatile flying machine in existence.
A helicopter is an engine driven rotorcraft using rotating blades to create the forces needed for flight and steering. Its ability to hover, fly backwards and sideways sets it apart from any other aircraft. A very important physics principle that applies to the flight of a helicopter is lift.
Lift is the force needed to keep the helicopter in the air. The rotors create the lift force, as the uniquely shaped rotor blades spin they push the air and the air pushes back with the same amount of force or more, but in the opposite direction causing it to move upwards.
Due to the main rotor spinning, the body of the helicopter also wants to rotate, but in the opposite direction. To control this you need a tail rotor. The tail rotor provides a force parallel to the helicopter, which stops it from spinning in circles.
Getting a grasp for the physics and math needed for flying is the first step to becoming a Medical Emergency Helicopter Pilot. You can expect to log many hours as a pilot and attend a post-secondary school. It is considered quite elite as far as careers go and hard work and dedication are a must. Responding to an accident because the ambulance is just too far away, even if the weather is terrible and the area was remote, is a very demanding career, but a very satisfying one.
Like Egypt, Sumer, and Mesoamerica, ancient China represents a hydraulic civilization—one that maintained its population by diverting rivers to aid in irrigation—and one that developed writing thousands of years ago. Today, we’re going to focus on the time of the Northern and Southern Song Dynasties, a time of great technical innovation. But, before we get to the Song, let’s take a tour through the ages and explore key elements of Chinese scientific culture.
The religion of Islam significantly influenced knowledge-making in the greater Mediterranean and western Asian world. Islamicate scholars—meaning people influenced by Islamic civilization, regardless of their religious views—gave us terms such as “algebra,” “azimuth,” “algorithm,” “alcohol,” “alkali,” and “alembic.”
We’ll dive into Islamic medicine and philosophers such as the great Persian polymath Ibn Sina in future episodes. For now, let’s explore the beginnings of Islamicate natural philosophy.
PHYSICAL SCIENCE
Build your very own trebuchet and catapult yourself to victory! You'll learn more about levers, simple machines, and the principles behind force and gravity as you experiment with projectiles and counterweights to make the perfect launch.
ABOUT THE SCIENCE
The trebuchet (pronounced tray-boo-shay) was a large counter-weighted weapon used in the Middle Ages during warfare to break down the walls of castles. The first ones invented used between 15 and 40 men to pull down the lever arm in order to launch it. It soon developed into a simple machine called a traction trebuchet that used gravity instead of manpower. These machines were generally larger and more difficult to reload, but could catapult much bigger objects.
Here is how it worked! It had a lever that transferred gravitational energy into kinetic energy, taking the force of gravity and using it to fling an object. Soldiers relied on this weapon so much, that they even named them! One very large trebuchet used during the Crusades in Scotland was named “Warwolf”.
No matter the size, the main components of a trebuchet are the lever and the sling. The pivot point (or fulcrum) is located between the load and the effort and works like a see saw. On one end there is the object that is to be fired and on the other is the counterweight. Raising the counterweight above the ground causes a buildup of potential energy. When the counterweight is released and falls, the lever arm pivots on its fulcrum and the other end of the projectile receives the energy.
Can you believe they used these on ships as well as land? You can probably throw a ball on land with pretty good aim. Next time you are floating in a pool or lake, try throwing a ball to the shore and see what these ship-bound trebuchets were up against.
This is a great introductory video to neuroscience. Understanding how the brain works can help students tap into their metacognition and be more successful learners.

Erlen needs your help to get some trucks out of the mine! Using your knowledge of hydraulic systems, sort the pistons to solve Erlen’s challenge all while developing your knowledge about mechanical advantage.
ABOUT THE SCIENCE
Hydraulic systems are used everywhere: mechanic's shops, elevators, and even in brakes in a car. Where else do hydraulic systems appear?
Large machinery, such as that used in construction, uses a mechanical system called hydraulics to be able to lift and carry large and heavy things. The hydraulic systems create force using cylindrical parts, called pistons that are connected by a hose or pipe and filled with a fluid.
When the force used to move an object over a distance (effort force) is applied to the input piston, the force is transmitted to the output piston as the oil is pushing through the closed system of pipes. When the size of a cylinder is changed, you can add force to the system in order to move a heavy load. In a closed system, the pressure in the hydraulic lift remains constant so the surface area of the pistons determines how the force of that pressure is transferred between them. This works well if the pump is designed to rest when oil is not required; like in a tractor.

An evidence-based program deisgned to teach youth to develop coping mechanisms for stress and anxiety.
More than 120 Regina Grade 4 and 6 students have been given some new "FRIENDS" to help them better cope with stress, as part of a pilot program in Regina Public Schools.
The Regina Qu'Appelle Health Region and Regina Public Schools teamed up this school year to offer an innovative pilot program to 122 students in Grades 4 and 6, giving them tools to help reduce and better manage stress, anxiety and depression. The program is funded by the RBC Foundation through its five-year Believe in Kids pledge.
"Children are experiencing more stress, and this can lead to physical and mental health problems," said Robert Stephenson, RQHR psychologist and Regina FRIENDS pilot project coordinator. "The FRIENDS program equips kids with coping tools at an early age, so they can be more successful in dealing with situations as they arise, hopefully preventing significant difficulties later in life."
FRIENDS is an acronym for the skills and lessons emphasized in the program:
-Feelings
-Remember to relax
-I can try! I can do my best!
-Explore coping plans and solutions
-Now reward yourself
-Don't forget to practice
-Smile and stay calm for life
A storytelling site by and for people with lived mental health experience. Helping to break down stigma by educating through stories and experiences.
We all have something to share from our experience with mental health, regardless of where we are in the journey, and this is what this blog is about.
This blog serves in 3 ways:
1) to facilitate those of you who have a mental health issue(s), or care about someone who has a mental health issue(s), to write about your experience for the purpose of telling part of your story and sharing your wisdom, by having it published on this site (click here for more info on Superhero guest blogging);
2) to give you the opportunity to read what myself and others have experienced and I hope with all my heart that will help you to feel less lonely and misunderstood and maybe even a little bit empowered; and
3) to educate others who are interested in putting themselves in the shoes of someone who has a mental health issue.

"As impactful as these times have been on each of us as adults, this pandemic has also deeply impacted our youth. Children and teens are spending less time with their peers, which can influence mood, behavior and mental health, as well as affect their development. Youth and adults alike—ourselves at Yoga Ed. included—are cycling through thoughts of “I’m fine, we’re fine” and “we are definitely not fine.” In this toolkit, you will find tangible, effective tools to nurture healthy communication and connection as we navigate this uncertain time.
This toolkit is designed as a resource for caregivers in order to:
Better understand your own mental health needs and the needs of the youth in your life,
Provide ideas for sustaining self-care practices, and
Learn practices to support connections between caregivers and youth."
