Isotopic Pennies
Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...
Curated OER
Chocolatium
Learners find the average atomic mass of M & M's. In this chemistry lesson, students are given a sample of the element chocolatium and the atomic mass of each sample. They then find the average atomic mass.

MASS, MASS – Who Has the MASS? Analyzing Tiny Samples
What is it worth to you? A hands-on instructional activity asks groups to collect weights of different combinations of coins and calculate weighted averages. They use the analysis to understand the concept of an isotope to finish the...
Curated OER
Isotopes of Pennies
Students demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.
Curated OER
The Average Atom - Isotopes
Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.
Curated OER
Cosmic Chemistry: An Elemental Question
Space scientists investigate the cosmic phenomena in order to search for answers to possible origins of the solar system. They consider the concepts of elements and isotopes. Data is analyzed looking at tje abundance of elements...
Curated OER
Atomic Structure and Quantum Theory
Students are introduced to the structure of an atom and Dalton's atomic theory through a short video and mini-lecture. They also take a look at the weight of mass and become familiar with the idea of quantum theory
Curated OER
Properties of Matter
Ninth graders explore the molecular structure of matter and how it can affect the physical characteristics of a specific material. They demonstrate that isotopes of an element have different masses. Students demonstrate that the rates of...
