Twizzler Decay: Modeling Radioactive Decay & Half-Life

In this lab, we’ll model half-life using Twizzlers as our "radioactive atoms." With each "cut," you’ll simulate the decay process, observing how the sample decreases step by step. By the end, you’ll see how half-life works and und...

Speed, Velocity, and Acceleration

Speed, Velocity, and Acceleration

In this video you are going to learn about quantities of motion: Speed, Velocity, and Acceleration! Join our physics class as Mr. Mickens, Matt, and Abeni explore how things move within our physical world. We will discuss the difference between Scalar and vector quantities, distance and displacement, drawing vectors, vector addition, the concepts, applications, and calculations involved with speed, velocity, and acceleration.

Atomic Structure and the Periodic Table

Atomic Structure and the Periodic Table

In this video you are going to learn about atomic structure and the Periodic Table of Elements. Atoms are everywhere and make up all matter! They are all structured differently and their protons, neutrons, and electrons cause them to all behave differently. Different numbers of protons, electrons, and neutrons cause them to be isotopes, ions, or completely different elements. They are all arranged on the Periodic Table of Elements. Whether you are teaching or studying for Chemistry or Physical Science, maybe you are just curious...COME LEARN WITH US and SHARE!
