Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Very simply, pairs of learners construct a model of the tetrahedral silica structure using raisins and toothpicks. They dip it into a soapy solution and then blow a bubble "atom" into its center. The lesson plan gives instructions that...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Teach your class to think of electrons as tiny packets of energy that travel in waves. Through a short video and diagram, participants see how electrons are located around the nucleus of an atom. They then get into groups and try to...

Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

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...

The VSEPR Model of molecular structure is exhibited through this series of slides. The step-by-step process is listed, and then examples are provided. The graphics give a visual display of the spatial relationship between the atoms of...

Delve into the world of quantum mechanics by viewing this PowerPoint. Chemistry novices learn about electron energy and shells, and they practice listing electron configuration for different atoms. Because this presentation provides...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.

What goes into a museum display? A secondary-level STEM project prompts groups to design a museum display for the Tech Museum of Innovation. They create an analogous, interactive model illustrating a science concept to complete the...

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...

Positive and negative numbers are everywhere in the world around us. Whether it's charged particles in atoms, a hot air balloon rising and falling in the sky, or a series of bills and checks being delivered in the mail, this...

In this Bohr model and wave mechanical model worksheet, students read about the differences between these two models of the atom. Students answer four questions about these models.

In this location of electrons worksheet, students read about the quantum mechanical model of the atom and the location of electrons. They complete a table given eleven elements with the sublevel notation, the Bohr notation and the...

In this atom learning exercise, students answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

Students construct models of hydrocarbon molecules using candy and toothpicks. In this hydrocarbons lesson plan, students are given a sheet with the molecular formulas of hydrocarbons. As a group, they construct each molecule using...

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. 

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...

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,...

In this atom worksheet, chemists learn how to determine the number of protons, neutrons and electrons in an atom using the atomic mass and atomic number. They complete a chart of the subatomic particles and use marbles to represent...

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 scholars investigate the structure of the atom through hands on activities. For this atomic structure lesson, students perform 4 activities showing indirect evidence of the structure of the atom and the parts of the atom. They also...

In this atomic structure worksheet, students answer eleven short answer questions about the structure of atoms including the number of protons, neutrons and electrons. Students indicate the differences in isotopes of atoms and what the...
