Isotopes and Atomic Mass – Determination of the Average Atomic Mass of Pastium
9th - 12th
Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...
The Periodic Table
7th - 11th CCSS: Adaptable
Whether you're giving a broad introduction to the periodic table or honing in on particular element groups, this collection will have what you need. I've put the general resources at the front, and resources that focus on particular element groups at the end.
Determining the Atomic Mass of Elements in a Compound Using Matrices
9th - 12th CCSS: Adaptable
Scholars apply concepts learned in both Algebra II and Chemistry to answer the questions on the provided worksheet. The activity allows for extra practice in both classes and helps connect concepts usually taught in isolation. The...
Chemistry: Introduction to the Periodic Table
9 mins 9th - 12th CCSS: Adaptable
Introduce your class to the most important table they will never dine on! From a larger playlist covering chemistry concepts comes a thorough walk through of the periodic table. The narrator details the structure of the table, how to use...
Stoichiometry: What Is Stoichiometry?
8 mins 9th - Higher Ed CCSS: Adaptable
Stoichi-what? If it's that time of year in your chemistry class, work a helpful video into you lesson plan! From JFR Science, the video discusses the fundamentals of stoichiometry at an easy-to-understand pace. Topics include mole...
Chemistry: Average Atomic Mass (AMU, Daltons, etc.)
7 mins 9th - 12th CCSS: Adaptable
Scientists created a new measurement, the atomic mass unit, which is defined as carbon 12 = 12amu. So why isn't carbon listed as having exactly 12 amu on the periodic table? An installment from the Socratica chemistry playlist answers...
Chemistry Simulations from PhET
6th - Higher Ed CCSS: Adaptable
Bring your science classroom into the 21st century with this collection of digital simulations. From an introduction to the states of matter to balancing chemical equations and investigating radioactive decay, these engaging interactives cover a wide range of topics in physical science and chemistry.
How Small Is An Atom? Spoiler: Very Small
5 mins 9th - Higher Ed CCSS: Adaptable
The hydrogen in your body is exactly the same as the hydrogen in the sun. The video explains just how small an atom is and offers comparisons, such as the one above, to help facilitate understanding. It also presents the current model of...
Mendeleev and the Periodic Table
5 mins 6th - 12th CCSS: Adaptable
Two hundred years before Mendeleev created the periodic table, scientists observed patterns in the elements and tried to sort them. The brief first video in a 15-part series explains the development of the periodic table and the many...
Why Aren't All Atomic Masses Whole Numbers?
4 mins 9th - 12th
Since an atom can't have a partial neutron, the atomic mass should always be a whole number, but it isn't! An interactive video lesson explains how the atomic mass number from the periodic table incorporates the isotopes of an element....
