Drawing Lewis Structures
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.
Regents High School Examination PHYSICAL SETTING CHEMISTRY 2007
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.
Types of Bonding and Intermolecular Forces
High school chemists chart the properties of different types of solids after considering their various intermolecular forces. They examine ionic and metallic bonding and draw electron dot structures for several different compounds. This worksheet is an ideal overview of these concepts and can be used as homework or an assessment.
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.
Photosynthesis: Light Reactions 1
This clip picks up right where the Khan Academy's Photosynthesis video left off. Chemicals such as hydrogen and compounds such as NADPH are reviewed along with details such as the stroma, thylakoid, lumen, and grana. See the parts of a chloroplast and how it functions to produce energy. The Photosynthesis: Calvin Cycle video takes a look then at the "dark reactions" or light independent reactions.
Periodic Table Trends: Ionization Energy
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.
Heterogenous to pH, pOH, and pKw
The auto ionization of water into hydrogen and hydroxide ions is the focus of this chemistry video. pH is a chemistry term that most people have heard. "What's the pH level of the water in our pool?" This video shows students, chemically speaking, exactly how water takes on pH ions.
Molecular and Empirical Formulas
An introduction to molecular and empirical formulas awaits your students. Sal uses the elements benzene, water, and sulfur to illustrate the ways to come up with a molecular and an empirical formula. Additionally, Sal shows students how to calculate the atomic mass of an element.
States of Matter Follow-Up
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.
Groups of Elements
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.
In 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.
Surface tension and Capillary Action
Young scholars explore the phenomena of surface tension and capillary action. They review density and bouyancy, observe Tokar's demonstration and complete a surface tension lab activity. In addition, they complete sample questions and assessment on the subject.
The Ties that Bind
In this bonding worksheet, students read about the types of bonds that hold compounds together. They are given fifteen common materials and they identify the types of bonds that hold each together.
Acids and Bases
In this chemistry learning exercise, students answer 50 multiple questions on acids and bases. They calculate the pH and pOH of acid and bases solutions.
The Point is to Make ATP
Storing and transferring energy is explained here with reference to the fight or flight response, along with the need for activity in times of lowered nutrition. This is a great summary of ATP applications, and after the multiple stages of respiration, your class will find this relevant because of the applications and impact of the biochemistry. This is the student version of the full PowerPoint which is also available on our site.
Summary of Periodic Trends
This concise collection of images speaks volumes about the trends in the periodic table of elements. Different versions of the periodic table are displayed demonstrating different trends. Teachers' notes are included to assist your lecture.
Student Reading - The Unique Properties of Water
Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that demonstrate each of the amazing properties of water, including: polarity, cohesion, specific heat, evaporation, density, and its role as the universal solvent.
In this molecular shapes worksheet, students draw the Lewis structures of 15 compounds and polyatomic ions to complete the table.
The Chemistry of Life
After studying the different aspects of atoms and their reactivity, students will find this summary PowerPoint useful for review. Some of the slides are informative with labelled diagrams, others require sentences to be completed with important vocabulary (not included). Teachers may want to take sections of this slide show to use as a supplement to other chemistry lessons.
Binary Molecular Compounds
A simple set of slides shows chemistry novices how to name binary compounds containing two nonmetals. Instruction and examples are given, making this a practical presentation for your class. Please note that the links to worksheets on the last slide do not work, so you will need to furnish your own practice worksheet for homework.
