Sal introduces students to the ways that atoms "stick together" by bonding. Students see that the process of atomic bonding is what creates molecules. He outlines specific examples of atoms combining through covalent bonding, polar covalent bonding, and metallic bonding. Previous knowledge of how electrons are given away and taken by elements would come in handy when viewing this presentation for the first time.
Sal continues his explanation of the states of matter by focusing on hydrogen bonds. This time, he uses plasma as the substance being studied, and explains how the hydrogen bonds change as the substance goes from solid, to liquid, to gas.
Students explore the different techniques used in forensic science. In this chemistry lesson, students investigate a fictional crime and identify the culprit. They create a brochure or collage career bulletin.
In this molecular shape worksheet, students read how the shapes of molecules can be predicted from their Lewis structures by using the VSEPR model. Students then complete 2 word problems, 1 drawing, and 1 graphic organizer.
For this main group worksheet, students apply their knowledge of the organization of the periodic table to correctly answer 30 multiple choice questions. Students relate information about the properties of the different groups and their reactivity to other elements.
In this chemistry worksheet, students answer 74 multiple choice, short answer and problem solving on various chemistry concepts.
After studying the different aspects of atoms and their reactivity, pupils will find this summary PowerPoint useful for review. Some of the slides are informative with labeled diagrams; others give important vocabulary. Teachers may want to take sections of this slide show to use as a supplement to other chemistry lessons.
Students observe replacement reactions by performing an experiment. In this chemistry lesson, students design an experiment to predict the reactivity of metals. They balance chemical equations using correct symbols.
In the previous video, Sal outlined what happens when a strong acid is put into reaction with another compound. In this presentation, he describes what happens when a weak acid is introduced. Sal explains why Hydrofluoric acid is much weaker than Hydrochloric acid, and shows how the molecules disassociate themselves from the weak acid much more rapidly than they do in a strong acid during a chemical reaction.
Element groups are located in the periodic table by blinking on and off. A slide is then dedicated to each of the groups, explaining which elements are included and what common chemical properties they share. This topic is presented in an attractive format for use in your chemistry class.
For this chemical bonding worksheet, students compare ionic bonds and covalent bonds, use Lewis dot structures to show transfer electrons, and balance equations. This worksheet has 17 word problems.
Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the physical properties of two compounds as determined by their types of chemical bonds. There are no student lab sheets provided, but the teacher's guide is thorough, making it easy to create lab sheets if you so desire.
Students study the reaction on iron in water, air, and sodium chloride. They create a situation that shows this process and gives them the opportunity to hypothesize what, why, and how. They keep records and do an oral and written presentation on how the results supported or disproved their hypothesis.
Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons and photons. They throw wads of paper to model the lighting of a bulb. This is a memorable activity that will make solar cell operation clear in their minds.
Dealing with various types of chemical reactions, this is a note-taking and practice problem worksheet. It has a professional appearance and is well-organized, identifying they type of reaction being taught down the left-hand side of the handout. For each type of reaction, there is a description, format, guidelines, and examples. Use this when introducing your chemistry class to the different types of chemical reactions.
In this chemistry olympiad problem solving activity, chemistry pupils solve eight problems on a variety of topics including periodic trends, phase changes, ionization reactions, catalysts and titrations.
In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded, and moving unshared pairs of electrons so that each atom has eight electrons.
The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles, including multiple-choice, short answer, problem solving, interpretation of charts and graphs. The content covers every topic within the typical general chemistry curriculum. 
If you need a summary of Respiration, then these 3 videos will be invaluable to your class. The actual reactions happening at the 3 stages of respiration are explained step-by-step with an explanation of every chemical bond broken or made in the substrates and products.
Ionization energy is the energy required to remove an electron from an atom while in its stable state of being. Students review what an ion is, and how much energy would be required to remove an electron from elements based on their position in the periodic table. Sal effectively uses a graph that has ionization energy on the vertical axis, and an elements atomic number on the horizontal axis to help illustrate ionization energy.
