Covalent Bonding
When it comes to covalent bonds, sharing is caring. Presentation covers the octet rule with multiple examples, Lewis Dot Structures with an example, and resonance. Presentation is the first in a five-part series.
Curated OER
Gases and Plasmas
Learners determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Accuracy of Carbon 14 Dating II
The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...
Adrian College
The Universe
Young scientists create a simulation of Hubble's law. Introducing the Big Bang Theory using balloons and a simple lab instructional activity, scholars complete a data table and perform analysis.
