The History of Atomic Theory, Atomic Structure, Isotopes and Atomic Mass are presented in three different sections of this power point with. You can see the different sections by the change in colors. You will go through the scientists and experiments which contributed to the synthesis of the Atomic theory. The next section will go over the parts of the atom. The last section will review isotopes and atomic mass. Students will also learn how the masses on the Periodic Table where calculated. The Atom Fold-Out Foldable is designed for secondary science courses. The anatomy of the atom is covered including valence electrons, energy levels, isotopes and ions. The Bohr diagram and Lewis Dot structure are reviewed. Students will also see what happens to an atom when the number of protons, neutrons and electrons are changed. I have included assembly instructions which is extremely simple and the teacher's key.

Electromagnetic Spectrum and Energy Power Point The power point covers the electromagnetic spectrum, light, photons, waves and their characteristics. the relationship between frequency, wavelength, and the speed of light are introduced with the formula for speed of light. Calculating the energy of the electromagnetic waves is also covered with introduction to Planck's constant and the energy formula derived using the constant. How we see light is presented along with slides for each type of electromagnetic ray and how they can affect human health. I also have a slide on cosmic rays since they have the most energy of all electromagnetic rays. Electromagnetic Spectrum Graphic Organizer (with energy and light formulas) The fold-out foldable covers the electromagnetic spectrum, light, photons, waves and their characteristics. The relationship between frequency, wavelength, and the speed of light are introduced with the formula for speed of light. Calculating the energy of the electromagnetic waves is also covered with introduction to Planck's constant and the energy formula derived using the constant. Electromagnetic Spectrum: Eight Types of Waves 1 pg Foldable This one page foldable has eight flaps for a description of radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma and cosmic rays. There are illustrations, instructions and a key included. Visible Light Spectrum: Speed of Light, Planck's Constant, Energy of Light In this worksheet students will use a visible light spectrum chart to calculate the wavelength of different colors of light. Then using the light equation and speed of light the students will figure out the frequency for each color. In the next step, students will use the frequency and Planck's constant in order to calculate the energy each color of light carries. Students will also need to color the spectrum. I have mine work out their calculations on a separate sheet of notebook paper and turn it in attached to their charts. I have included an answer sheet so you can see what the final should look like. For my younger students I give them the color wavelengths. For my physics students I have them use the chart and figure the wavelengths out on their own. I use this in both Chemistry and Physics.

This foldable covers six types of chemical reactions; synthesis. decomposition, single displacement, double displacement, combustion and acid / base reactions. Student sheet allows for definitions and student notes. The teacher key has the answers and is set up just like the student printable for ease of grading and checking notes. There is also a half page dichotomy key that students can use while they are classifying chemical reactions. It is is a series of yes / no questions that will guide the students to correctly labeling their chemical reactions.

This one page graphic organizer covers eight evidences of chemical reactions; color change, odor change, temperature change, indicator change, gas formation, precipitate formation, composition change and the irreversibility of chemical reactions. The foldable is simple to photocopy front to back. The students have areas to draw examples they can relate too and the teacher key includes common instances of chemical reactions students will be able to identify with. The inside portion of the foldable has places for students to write descriptions and list examples of each type of chemical reaction evidence.

This is a one page foldable which is photocopied front to back. It gives students a overview of chemical reactions. The Law of Conservation of Matter / Mass, balancing chemical reactions, coefficients, subscripts , reactants and products are all covered. Students will be able to identify the parts of a chemical reaction and count atoms to make sure they are balanced for the reactant and product sides.

The Atom Fold-Out Foldable is designed for secondary science courses. The anatomy of the atom is covered including valence electrons, energy level, isotopes and ions. The Bohr diagram and Lewis Dot structure are also covered. Students will also see what happens to an atom when the number of protons, neutrons and electrons are changed. I have included assembly instructions which is extremely simple and the teacher's key. EXCELLENT RESOURCE FOR ANY CLASSROOM!

A new twist on a dimensional analysis (factor/ label method). This activity is for after you have taught dimensional analysis. Students need to apply the skills they learned to see if they can escape in time to avoid the incoming zombies. You can have the students compete individually or in groups and which ever individual or group gets the six problems correctly answered first is the winner. There is a worksheet for the students, a Zombie Survival Fact sheet with some conversions. The students will need to use the information given to make their own conversion statements. I have included a teachers key with equivalency statements and how to solve the problems step by step. Student worksheet (3 pages) Zombie Key (1 page) Teacher Key (3 pages)

This is a great worksheet for getting to know the periodic table. The worksheet covers all 118 elements. I included a FREE downloadable periodic table that I used in making the scavenger hunt. This is specific for secondary students because your students may need to do a little research into the meaning of Latin and Greek words, look up mythological beings and celestial bodies. This scavenger hunt is excellent in informing the students of how certain elements got their names and where groups are found. The Teacher Answer Key is included.

It is often difficult to hold secondary science students' attention as we get closer to Christmas vacation. Use this Christmas themed dimensional analysis activity to review your students' calculation skills while keeping them engaged and in competition. Your students will need to help Santa and the elves move through a myriad of crazy problems brought to them through oversight, Krumpus and the Grinch. A student guide sheet and detailed teacher's key is included. There is also an additional "emergency problem" for the students to work through. There is a second student guide for students who have a hard time creating their own conversion statements.

Power Point: Electron Configuration is covered in detail explaining Quantum numbers and how they relate to each other. This power Point is designed for secondary science courses and includes practice problems within the power point with answers. Standard electron configuration, noble gas configurations and the electron configurations of ions are all covered and include practice problems. Orbital diagrams are explained with practice problems. There is a student handout included that has the slide number and problems on it so students can work the problems out along with the power point presentation. The handout is one page front and back. GRAPHIC ORGANIZER: Electron configuration and orbital diagrams can be very difficult for students. This fold-out foldable presents the main components with practice problems. This is a useful foldable that students can continuously review while working on electron configuration and orbital diagrams.
