Scholars build specific elements by creating a model of its atomic structure. Objects they can include are protons, nuetrons, electrons, orbits, clouds, charge, and mass number. Simulation ends with questions to challenge individuals'...

Dispel the misconception that atoms are always little round balls! Illustrate changes in the electron cloud with an entertaining interactive. Pupils push and pull on the cloud by altering the charge on plates located on either side of...

In a simple activity, physical scientists model nuclear fission using a droplet of oil. This can be used alone in a unit on different types of energy, or as part of the energy conservation unit produced by the Texas State Energy...

This is one sticky situation! Science sleuths uncover the mystery behind a balloon that appears to be stuck to a wall using an interactive. Learners observe a neutrally charged wall before they manipulate the charge on a balloon. Atom...

Neatly organized and easy to read, this chart summarizes five different molecular shapes: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. It associates shapes with electron pairs and atom arrangement and lists...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Take your chemistry class' knowledge of molecular geometry to the next level! Introduce orbital hybridization with a series of related games. Individuals complete a data table in the first activity, then solve Sudoku-like puzzles using...

A simple activity for introductory chemistry classes is thoroughly explained in this lesson plan. Each individual receives a sealed box containing an unknown object. Inquisitors use indirect evidence to draw conclusions. This activity is...

In this chemistry worksheet, students fill in the chart for question one. The chart is filled out examining the mass, protons, electrons, and neutrons for specific atoms.

Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a...

Get a charge out of a great resource! Scholars use an interactive to explore addition and subtraction of integers. They add or remove electrons in an atom model to consider its charge.

In this periodic table worksheet, students answers 10 fill in the blank questions by reading information form a periodic table. Then also complete Bohr Models of the atoms of 12 different elements.

Atomic theory, a periodic table, and a place to practice making atom models without having to draw every proton, neutron, electron, and orbital! This resource is colorful, visually pleasing, and easy to use. 

When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass...

This PowerPoint is a comprehensive review of all the facts related to an atom's basic structure and function. What makes this unique is that it is geared toward an audience of junior geologists. After introducing the periodic table of...

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....

Learners see how electrons are transferred in the bonding of NaCl. They then create models of NaCl using styrofoam balls and toothpicks to assist them in explaining the formation of ions and ionic bonding. 

Atomic bombs harness the power in the nucleus of an atom, creating devastating power and damage. Classes review parts of an atom by charging a piece of plastic and holding it near their fingers, discussing what is happening and why....

The fifth lesson of seven in the series outlines an in-depth analysis of the periodic table. After direct instruction, pupils take turns practicing in the group before beginning independent study. The assessments include a...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

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.
