Students explore the concept of lethal dose (LD50) and research the LD50 for caffeine. Students will then research the amount of caffeine in one of their favorite beverages like Red Bull, Monster, Mountain Dew, coffee, etc and determine how much of their favorite drink could potentially be fatal. Students are asked to provide evidence of research and to show their thinking. Step-by-step procedures are provided or they can be removed to challenge students to create their own research procedures.

Use this handout to introduce how gases behave alongside a PhET simulation. Students will learn about conceptual gas behavior, develop personal definitions of volume, pressure, and temperature, as well as explore the following gas laws: Boyle's, Charles', Gay-Lussac's, and Combined Gas Law. Activity is self-guided and a great start to your gas unit.

This 3-page worksheet can be copied and laminated to allow students the ability to explore how ions bond based on charge. For example, a calcium puzzle piece has two notches to represent +2 charge. A fluorine ion has one notch that can fit with calcium to represent a +1 charge. Two fluorine pieces will fit one calcium piece. This can be used to teach monatomic and polyatomic ionic bonding.

This assignment guides students through properties of the periodic table such as organization (groups, periods, group names, phases), history (Mendeleev, Moseley, and more), element discovery, videos on specific elements and their reactivities and unique properties, and periodic trends (electronegativity, atomic radius, ionization energy and more). The assignment is designed to help students explore on their own while providing an opportunity for accountability. Great for differentiating instruc

This simple grid prompts students to use the periodic table to identify atomic number, atomic mass, protons, neutrons, and electrons. They then will draw the correct Bohr Model of the first 16 elements and draw the corresponding Lewis Dot Diagram with appropriate number of valence electrons. A blank page is provided so you can customize the worksheet for larger elements. An example has also been completed along with tips for completing each section.

CHEMISTRY: Students will review Quantum Mechanics by learning Aufbau Principle, the Pauli Exclusion Principle, and Hund's Rule. Students will also practice writing electron configurations, noble gas notations, and orbital notations. A WebQuest worksheet is also attached to help students visualize the 3D orbitals.

Students will use two PhET Simulations to explore (1) how Thomson's Plum Pudding Model of the atom differs from Rutherford's Nuclear Model of the atom and (2) how Bohr Models are used to make predictions about atomic structure. Isotopes are also briefly explored. This can be used for distance learners and in-person traditional settings or hybrid-style classrooms. Can typically be completed within a 45-minute period but can be used in a 90-minute block with additional resources.

Students will use a linked website to walk them through how to draw Lewis Dot diagrams in covalently bonded molecules. This assignment is designed for students to complete on their own or in a computer lab with minimal instruction from the teacher. Lewis Dot diagrams can be very complex and there are a variety of exceptions, but not in the handout. Students typically find this assignment to be easy.

Students explore concepts of stoichiometry, balancing equations, calculating molar mass, limiting/excess reactants, theoretical yield, and percent yield in this easy lab using baking soda and vinegar. The pre-lab questions prime students with a fictional lab scenario so prepare them for doing their own quantitative lab. An answer key for the pre-lab questions and suggested answers for various quantities of baking soda and vinegar are provided.

This worksheet is an excellent review of gas laws. It includes practice problems on the following topics: combined gas law (including Boyle's Law, Charles' Law, and Gay-Lussac's Law), the ideal gas law, gas stoichiometry, and conceptual gas scenarios). Includes problems at STP (standard temperature and pressure) and non-STP questions. The end of the worksheet also includes four standardized test questions related to gas laws. This is an excellent preview, overview, or review for a gas unit!

Students will practice with the following topics: metric conversions, SI units, rounding significantly, identifying significant digits, converting between standard and scientific notation, solving for mass/volume/density, using percentage error, precision/accuracy, and dimensional analysis with on unit and with two units.

This bundle includes an introductory lesson (Bacon Double Cheeseburger), a lesson designed to practice stoichiometry problems (Stoichiometry Practice), and TWO application labs! This is everything you need to begin your stoich unit, practice, and stretch your students. BONUS Resource Includes: Editable Stoichiometry Assessment!

Designed for an AP Chemistry class or college-level Chemistry course. A quiz or practice worksheet covering equilibrium reactions. Topics include: writing equilibrium expressions, using ICE (or RICE) tables to solve for equilibrium concentrations, converting Kp to Kc values, interpreting large or small Keq values, reaction quotient Q, Le Chatelier's Principle, how reactions shift to reduce a stress in an equilibrium system, and using the Reciprocal Rule to calculate the Keq value for a reverse r

This bundle includes ALL THINGS Gas Laws! Practice problems with answers, conceptual gas behavior scenarios, application of a variety of gas laws such as Boyle, Charles, Gay-Lussac, Combined, and Ideal. These activities also include gas concepts such as the Kinetic Molecular Theory, Standard Temperature and Pressure (STP), standard molar volume of 22.4L/mol, and some other great surprises!

In this lab, students will carry out a single replacement reaction using aluminum and copper (II) sulfate to produce aluminum sulfate and pure copper metal. Through gravimetric analysis and stoichiometry, students will predict their theoretical yield, calculate their percentage yield, and identify typical errors. In summary, students use a hot plate to warm a solution of copper (II) sulfate and a known amount of aluminum foil. Once the reaction occurs, solid copper forms and the aluminum foil se

Use this fill-in-the-blank periodic table to help students learn the trends for writing electron configurations, noble gas notations, and orbital diagrams in terms of the Quantum Mechanical Model of the atom. Includes information on Hund's Rule, Aufbau Principle, and Pauli Exclusion Principle.

Students will balance nuclear reactions (written in isotope notation) and explore alpha, beta, and gamma decay. This worksheet also includes a table with nuclear particles such as alpha, beta, neutron, positron, etc.

This worksheet provides space for students to practice drawing Lewis Diagrams of covalent molecules with the use of single bonds only. It also has a section that reviews naming ionic and molecular compounds. This assignment begins exploring the concept of VSEPR (valence shell electron pair repulsion) theory by having students identify how many atoms are attached to the central atom and the number of lone pairs associated with the central atom. This concept can be explored further or skipped depe

Students can explore various gas law problems, including Ideal Gas Law, Combined Gas Law, and Boyle/Charles/Gay-Lussac. Students will solve mathematical problems and answers conceptual questions as well. There is a bonus question that incorporates the Ideal Gas Law and the concept of Molar Mass. This is an excellent quiz for honors and advanced courses, but can also be used to enrich beginning-level courses. Answer is provided with work shown.

This lab addresses the following types of reactions: synthesis, decomposition, single displacement, double displacement, combustion, and acid-base neutralization reactions. There are 9 reactions that students can perform through rotating stations or in lab groups, depending on your prep time. I suggest having students identify the type of reactions and predict the products as a pre-lab activity, and then students can perform the lab and answer the questions.
