Cycles are a big deal in engineering. Today we’ll explain what they are and how they’re used in heat engines, refrigerators, and heat pumps. We’ll also discuss phase diagrams and the power of using renewable energy resources
Today we’re talking about heat transfer and the different mechanisms behind it. We’ll explore conduction, the thermal conductivity of materials, convection, boundary layers, and radiation.
Hank and his brother John discuss heredity via the gross example of relative ear wax moistness.
Media Description | 5 minutes We're diving for data! With the help of an “eye in the sky” and some savvy scuba surveyors, researchers are estimating the number of herring in the water... by counting their eggs! But modern methods can only tell us so much. To get the full picture, we turn to the people who know the herring best. If you like this content you can see all of the available resources in the Harvest module in the Ocean School Help Centre (https://help.oceanschool.nfb.ca/educational-resources/module-guides/the-harvest-module-guide). >> Activity Description | 5 minutes'Herring census' - Stock assessment survey: Students are challenged to determine which herring stock will most likely have a healthy population in the future! Students perform a herring census using a simplified version of the methods used by scientists at Fisheries and Oceans Canada. An additional data sheet is available with this activity: https://docs.google.com/spreadsheets/d/1BRhtQ3t1PEN3wHJwtZTuELdVH3hnC56jjCCXEFBw95I/template/preview

Today we’ll cover the fourth and final of our core disciplines of engineering: chemical engineering. We’ll talk about its history and evolution going from soda ash competitions to oil refineries and renewable energies. We’ll also discuss some newer and emerging fields like biotechnology and pharmaceuticals.
Option 1: RESEARCH Top 3 flight contributions
CRITERIA:
Create a magazine entry or a digital story telling creations, which includes 3 paragraphs (& pictures) on what you consider to be the top 3 biggest contributions to flight. Make sure to list your references. If you are doing a digital story telling creation you will only need a rough copy and not a good copy.
Make sure you are including how it impacts humans and your daily life.
Option 2: Create an online timeline
Create a timeline using an online tool from one of the tools suggestion from the article below (or any other ones you may find!):
With a solid understanding of biology on the small scale under our belts, it's time for the long view - for the next twelve weeks, we'll be learning how the living things that we've studied interact with and influence each other and their environments. Life is powerful, and in order to understand how living systems work, you first have to understand how they originated, developed and diversified over the past 4.5 billion years of Earth's history. Hang on to your hats as Hank tells us the epic drama that is the history of life on Earth.
How would a Polar Bear do if you put it in the desert? Not well. But why? Why can't anything live anywhere? Well, this has to do with Habitats and how animals (including humans) are suited for living in one place over another. In this episode, Sabrina talks about how these Habitats form Food Webs and how those Food Webs help us understand a lot about the world.
Solving food shortages caused by droughts is a big challenge that may benefit from a tiny ally. Turns out that the microbes living in the soil around plants can give them a boost when water's scarce, which means more food for us, which is a big win!
Science Background: Light travels in straight lines, and this activity allows students to observe light and think critically about how they experience light in their lives. A common misconception for students is that the light comes from their eyes to light up the object, so drawing rays as arrowheads that show the direction of the light is a key concept.
Materials: index cards, ruler, coloured markers or pencils, hole punch, sticky tack, drinking straw, flashlight or ray box, beaker or glass, water
Science Background: Sound waves behave in the same way as light and water waves. This activity allows students to “see” sound.
Materials: plastic wrap, small yogurt container, elastic band, 1mL salt, tuning fork, water
In this episode we looked at robots and the engineering principles of robots. We learned how robots use sensors to interpret their environment, how actuators and effectors allow a robot to manipulate the objects around it to accomplish a task, and how computers coordinate the efforts of the two.
Today we’re going to explain how exchangers...exchange heat. We’ll look at concentric tubes, finned tubes, plate heat exchangers, and shell-and-tube heat exchangers. And we’ll look at some equations to help us sort through heat transfer and decide what heat exchangers are best suited for our designs.
A lesson plan for 4th grade science. Kids create a version of the marble roll project to simulate a manufacturing process.
In agriculture, it is important to have healthy soils. Learn how the laboratory at Dairy One analyzes soils and why the information they gather is vital to growers.
Join Proton the cat as he tests out the professor's newest invention - goggles that allow a person to see sound in addition to hearing it. As you take a tour of the lab, you'll learn all about the science of sound, from how our ears allow us to hear sound, to the differences between louder and softer sounds.
Ever wonder why you can’t hear a dog’s whistle, yet when you use one, all the neighborhood dogs come running? Dogs are able to hear at higher ranges than that of humans.
Sound is a type of energy created by a rapid back-and-forth movement or vibration. When an object vibrates in the air, the air particles move around and cause other particles to move and bump into other particles, which carry the vibration through the air. This sound wave will keep going until it runs out of energy. When your ear is in range of the sound wave (before it loses all its energy) you hear a sound.
Sounds differ from one another because they vibrate at different speeds. This means, how often a sound wave will occur over time, or its frequency. When the vibrations are fast, you will hear a high note, and when the vibration frequency slows, the note will lower. Your ears collect and process the sounds, and then send signals to your brain in response
In this episode of Crash Course Kids, Sabrina talks about how humans get the resources we need to survive, even though those resources may come from a long way away.
Scientists require interaction and teamwork to do their jobs, so it’s important to build that kind of culture with every student in the science classroom. This can be done by:
1. Creating a safe, equitable space.
2. Connecting to humans in the real world.
3. Integrating other disciplines.
4. Supporting the development of interpersonal skills.
In this article, you will find access to "Science Connections: The Podcast" as well as an infographic that will help to inspire the next generation of scientific innovators.
Lessons describe key functions of the human body systems.
