This is a quick worksheet that explains the story of Archimedes and the crown problem. There are followup questions afterward to reinforce the concept of the principle and bouyancy. Answers are included.

This is my lecture of simple machines. It is an introductory lesson with animation, drawings, and examples. It ends with a lesson on Mechanical Advantage. The demo will help give an idea of how the animation works.

This is a good power point to teach students the characteristics of four bonds (Ionic, Covelant, Polar covelant, and metallic). Then the power point moves on to how to naming compounds using rules and color coding. Naming schemes included are for Ionic bonds, Covelant bonds, compounds containing transistion metals and polyatomic ions. Please load the preview so you can see how it works. There are also pracice slides with answers at a click.

This powerpoint is for the steps in meiosis. There is discussion at the beginning about the chromosomes and a short review of the parts of a chromosome. At the end, mitosis and meiosis is compared and contrasted. A demo is included to show the type of animation in the powerpoint.

This powerpoint is a good introduction to the periodic table covering how to identify the parts of a box, color coding the phases and types of elements, and the four important families with descriptions. The power point is animated to give small bits of information at a time on each click.

This is a simple worksheet to show how the average mass is calculated by several methods. The first is by multiplying the number of atoms my their mass and then adding them up to average. The second method is having the percent abundance of each isotope to calculate average. This is a no frills straight forward drill sheet.

This is a good powerpoint for an introductory class of physical science or middle school science. It describes the parts of an atom, the 1st four orbitals, and how to determine the number of protons, nuetrons, and electrons. The powerpoint is animated to give small bits at each click of the mouse. The demo will give you an idea of how it works.

This is a lab that has little maintenance and can be done easily. This lab describes plating a washer or any iron object in copper from pennies. There can be a couple of variations done at once like using a battery or not and of course the amount of pennies. Included with the lab is a cover sheet of tips and suggestions for the lab, answer sheet, and pictures of the lab and results. I have about 20 labs in this format and will either post them or have a disc that can be sent.

This powerpoint introduces balancing equations to an audience that has not done balancing before. The powerpoint is set to only give bits of information after each click of the mouse. I have found that this step by step process of balancing works for many of the introductory equations that will be seen in an introduction to balancing. The process helps with balancing polyatomic ions and oxygens with ease. There are also examples and practice problems. You will notice that the last two slides of

This lab is designed to be used with the Hot Wheels type track and cars. I am sure that any ramp with a rolling object would suffice also. This lab has a helpful hints page, the student handout, answer sheet and a make up lab for those who missed the lab day. This is a lab that is included in the lab book I offer.

The steps of the scientific method as I present them in class. I use the definition of prediction for Hypothesis since I feel that "educated Guess" does not make sense. There is also a guide to making a good graph with a chart to make the three basic types. The matter is straight forward and simple which includes solving for density and the particle theory of phases. I have a slide that says "Archimedes Day." This is where I have a lesson discussing Archimedes principle and how things float. It

This PowerPoint covers these topics: General vocabulary used with nuclear reactions, Alpha particles, Beta particles, Gamma rays, strength of radiation, Alpha/beta decay, fission, fusion, half life, and natural sources of radiation. This PowerPoint is animated for pacing of lesson.

This PowerPoint is intended for a higher level of chemistry. It covers the Rutherford model, Bohr model, and the quantum mechanical model of the atom. There is slides that cover calculating the numbers of electrons, protons, and neutrons. There is also slides that explain how to write the Electron Configuration Notation, Abbreviated Electron Configuration Notation, and the Orbital Notation of the atom. Slides have animation to help with pacing of the lesson to the speed of the teacher.

This is hands down the easiest, fastest, most reliable way to solve stoichiometry problems. I am not kidding. THE BEST. I call it the chart method. This PowerPoint has gram to mole conversions and % composition also. The instructions for stoichiometry are clear and procedural. If you are looking for your students to save time on timed tests, this is the method for you. My chemistry students ask for this when they get to college since the traditional method is crazy lots of work. An example for l

This is a simple decomposition lab where you use just a 9V battery to split water. This lab includes tips and hints and an answer sheet. This is another lab from the 20 or so I have that is included on a disc to be sent.

This is a neat lab for you to do in class! You can grow your own crystals. This is another lab from my lab book I have created. It has a cover sheet of hints and things to look out for. It also has an answer sheet. I have about 20 of these types of labs that I will either post individually or included on a disc to be sent.

This is a kinesthetic lesson to use for showing the bonding between two oppositely charged Ions. The students will cut out shapes of paper that they will label as Ions with charges and then put them together in the right configuration. When done, they will have a picture of that a molecule with the right ratio of atoms. This is a good way to show the students who atoms combine in their ratios.

This is a powerpoint covering the basics of waves covering transverse, longitudinal, and wave interference. I use this powerpoint to introduce waves and types of waves before I go into talking about light and sound. Each slide has animation to click to set the pace of your lecture. Please try the demo to get an idea of how it flows.

This PowerPoint is geared towards a higher level of chemistry. Topics include parts of a periodic table box, Isotopes, calculating average atomic mass (worksheets available to download too), Moles, Mole conversions, scientific notation, properties of the metals/metalloids/nonmetals, families of the periodic table, valence electrons, Lewis dot structure, and trends of the periodic table. It usually takes me a couple of weeks to get through his material with activities and class reinforcement. Sli

This is a simple lab that uses cabbage juice, litmus paper, and universal indicator paper. It is pretty straight forward and simple with the used of everyday household chemicals. It includes a helpful hints page with the student lab copy, answers sheet, and a make up page for those who miss the lab. This is a lab that is included in the lab book that I offer.
