Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Teaching young scientists about atoms is no small task, but this series of worksheets will make it a little easier. From creating and labeling Bohr models, to identifying information provided in the periodic table of elements,...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Get to you know your new class members with an ice breaker activity that uses their name and creativity. Scholars write their first name in cursive on a folded sheet of paper, cut around the curved lines, open the paper to view its new...

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Activity 4 of this module determines: Which model best supports our observations? This activity reviews the evidence gathered in this investigation and considers how that evidence informs your model of matter. A timeline of the history...

Short slide show provides basic information about drawing Lewis dot structures for covalent compounds. Starts with anatomy of the atom, and then shows the relationship between atomic particles and the Periodic Table of Elements. Offers...

A tutorial that explores the concepts of heat and temperature, the transfer of energy between substances, the relationship of temperature and the movement of atom, and thermal radiation. The tutorial includes animations, interactive...

Students construct a model of chemical reactions involving energy and electrostatic interactions and compare reactions and changes in energy through the following activities. Activity 1 What energy changes occur during an explosion?...

This lesson explains what is represented by the atomic mass, and how it varies from one element to the next. Module includes a slideshow and a quiz.

This module develops atomic-level causal models to explain observations of electrostatic interactions via the following activities: Activity 1. What is the effect of changing the composition of an atom? Activity 2. How do objects become...
