Halloween Slime Pumpkin Volcano Experiment Background Information: Pumpkins with ghoulish faces and illuminated by candies are a sure sign of the Halloween season. The practice of decorating jack-o’-lantern originated in Ireland, where large turnips and potatoes served as early canvasses. In fact, the name jack-0’lantern, comes from an Irish folktale about a man named Stingy […]
This lesson includes an Electron Configuration Worksheet, Guided Notes, Power Point Presentation, Exit Quiz, Vocabulary Activity, and much more! Start your lesson with this... The Atomic Number Revisited: The atomic number tells us the number of protons an atom possesses. In a neutral atom, the number of protons and electrons are equal. Therefore, the atomic […]
Isotopes are different forms of the same element which have the same number of protons but differ in their number of neutrons. A variation in the number of neutrons in the nucleus causes the atom’s mass to change. Many elements on the periodic table have naturally occurring isotopes. What are Isotopes? Isotope Names: In most […]
The Basic Structure of the Atom: Atomic Structure Atomic Structure: All atoms consist of a nucleus which contains two types of subatomic particles - protons and neutrons. The nucleus is surrounded by a cloud of electrons at varying energy levels. These subatomic particles are composed of even smaller particles known as quarks which came together […]
Origins of the Atom The structure of the atom as we know it has been developed over hundreds of years with a number of scientists building on the current knowledge of the time. The concept of the atom was first hypothesised by two Greek philosophers, Democritus and his mentor Leucippus in the fifth century BC. […]
What is an Atom? When starting your lesson on Atoms and Molecules make sure to start with the Atom and the changes that have been discovered. Atoms are the simplest building block of matter. Originally, it was thought that atoms were indivisible. However, we now know that an atom can be broken down further, although […]
Kinetic Molecular Theory of Matter Matter is made up of particles which are in constant, random motion. It can be defined as anything which has mass or occupies space. Matter is classified by its state and type, of which there are three main types – solid, liquid and gas. These lead us to the Kinetic […]
The History of the Periodic Table of Elements Many of the elements from the periodic table we know today were originally discovered by the early chemists who worked to purify ores. In doing this, they realized that certain elements showed similarities in their properties and were, therefore, able to be grouped together. For example lithium […]
Here are 3 Black History Month Scientists your Students Should Know: Dr. Mae Jemison James Andrew Harris Dr. Warren M. Washington Celebrate black history month in your chemistry class this February by teaching your students about the trailblazing African American scientists below. 1. Black History Month Scientists Spotlight: Dr. Mae Jemison and Bottle Rockets Dr. […]
Nuclear Equation Role-play Types of Radiation in Chemistry Background: Knowledge of what happens when a radioactive nucleus undergoes decay is the key to understanding how to balance nuclear equations. This activity uses role-play to build on and develop an understanding of the atom and radioactive decay, as well as explaining the concept of nuclear equations. […]

Exothermic or Endothermic? Background Information and Theory: Bond Energy and the Types of Reactions Endothermic and Exothermic: During a chemical reaction, energy is either transferred to or from its surroundings. Reactions which involve heat energy being released into the surrounding environment are called exothermic reactions. By contrast, endothermic reactions draw heat energy from their surroundings. This […]
Chemistry Magic Triangles Background Theory: In Chemistry, the measure the amount of a substance in a unit is called a ‘mole’. It is a convenient way of counting atoms and allows chemists to make predictions about the masses of different substances that are involved in reactions. Regardless of the element in question, one mole of […]

Flame Tests – Identifying Metal Ions Atomic Structure Lab Activity Background and Theory Chemists are often required to test samples to find out if they contain specific ions or compounds. This lab allows students to practice these techniques and identify the different metal ions. When atoms are heated they become excited causing the electrons to jump into higher […]
