Many people know about how redlining, inequitable home buying policies, and its effects on the wealth of people of color. However, few have discussed how redlining has impacted the cities and communities where it historically occurred. A recent study from Yale university documented how poor city planning and redlining policies can be linked. The results are urban heat islands where communities are negative impacted in a number of ways. This lesson teaches the fundamentals of climate change, while allowing students to explore the how public policy also plays a role in climate change.
Teaching science can be a difficult task. It requires a unique understanding of science content, student culture, and language.
Who doesn’t love bubbles! The things with bubbles is that they offer a quick and easy way to view how electrostatic forces impact small interactions. In the bubbles we see, there is an interesting effect, where the maximum distance of the surface tension is a globe. However, have you ever seen bubbles in different shapes. This lesson explores how making square bubbles might be an option.
A vortex ring is a circular shaped ring of spinning gasses that move together as a unit. A vortex ring can happen in liquid or gasses, but are rarely seen because they happen inside of liquids or gases. When a vortex ring happens inside of suspended particles—as in the smoke rings which are often produced by smoke they can be seen. Visible vortex rings can also be formed by the firing of certain artillery, in mushroom clouds, and in microbursts.
A vortex ring usually tends to move in a direction that is perpendicular to the plane of the ring and such that the inner edge of the ring moves faster forward than the outer edge. Within a stationary body of fluid, a vortex ring can travel for relatively long distance, carrying the spinning fluid with it.
Slingshot physics involves the use of stored elastic energy to shoot a something at a high speed. This elastic energy comes from rubber bands which are specially made for slingshots. This energy is provided initially by the muscle energy of the slingshot operator. One of the goals of a slingshot is to fire the projectile at the greatest speed possible. To do this two basic physics conditions must be satisfied.
Admit it, slime is simply awesome! Kids will make slime at home in their spare time, but what it the science of this uber relaxing materials. This lesson prepares your students to understand how substances engage in the formation of Polymers. The discussions of polymers can start at slime and explore environmental justice. Enjoy this engaging interpretation of slime.
Flick a switch and get instant power—We loved to use electric motors even when we don’t know we are using them! You can find them in everything from electric lights to to remote-controlled cars—and you might be surprised how common they are. How many electric motors are there in the room with you right now? There are probably two in your computer for starters, one spinning your hard drive around and another one powering the cooling fan.
Genetics plays an important role in our life. How often have you wondered why someone’s brother or sister looks dramatically different from them. Our genes operate by a set of rules that we should talk about more often. Each parent has gene that split in half, scramble and then resort for replication. Even after that there are environmental factors that cause the genes to work. This lap uses simply marshmallows to teach this idea.
Students create their very own projector in this lesson to study optics.
Students explore Bernoulli’s Principle in relation to atmospheric pressure and volume in this lesson.
Inertia and centripetal force are hard topics for students to learn. Through this lesson, students will explore these topics in relation to changing designs of Fidget Spinners with different weights (mass).
By making cars that are propelled by a fan, students in this lesson learn about motion, force, and circuits. This lesson also leverages engineering design skills for students to iteratively think about how some designs work ‘better’ than others.
By exploring the influence pressure has on a closed system, students in this lesson will gain a better understanding of air pressure.
By observing changes in density, students in this lesson gain a more complex understanding of air pressure and density.
By making observations about the impact temperature has on heated gases, students in this lesson are provided with a phenomenon-based learning experience to gain a more complex understanding of gases in relation to temperature and volume.
Gases and liquids have similar movement patterns. In chemistry classes students will learn about the Bernoulli’s principle. This concept of fluid movement can be difficult to understand. Years of teaching science taught me to use example like digging up sand and having new sand fill the void. This simple outdoor activity can serve as a simple introduction to understanding this key gas principle.
Sports and dance provide a wealth of opportunities to learn science. This introductory physics lesson explores the physics of landing. Many young people experience traumatic injuries that are the result of landing from a jump. The impact of their bodies hitting the ground after accelerating from a height magnifies the weight of their body onto…
