In this elements instructional activity, students classify elements based on electron configuration and identify representative elements and transition metals. This instructional activity has 11 fill in the blank, 4 true or false, 7 matching, and 2 short answer questions.
For this writing chemical reactions worksheet, students solve 15 problems on their own paper using a 3 step-problem solving approach. In addition, students write six balanced equations and classify each reaction. They also write equations in aqueous solutions.
In this stoichiometry worksheet, students solve 4 problems using the 3 step problem solving approach, they do 8 chemical calculations and they solve 6 percent yield and limiting reagent problems.
In this chemical formulas instructional activity, students answer 5 multiple choice questions and they practice naming compounds and writing formulas for 15 questions.
In this introduction to chemistry worksheet, students answer 9 questions regarding the study of chemistry. The first part is matching, then they "think like a scientist" and then they problem solve.
In this measurements instructional activity, students answer 26 problems about measurement. These include questions about uncertainty, conversion problems, density and the international system of units.
On "Defining the Atom," physical science starters fill in blanks, determine if statements are true or false, match terms with the appropriate definitions, and solve problems. Questions are about Dalton's atomic theory, the atom and its general composition. This is a compact and applicable homework assignement for any general chemistry class.
Vocabulary that is essential to this topic is introduced and defined at the start of this slide show. The following slides help students understand proteins and their use and involvement in everyday substances. Great diagrams help your class understand the overall appearance and behavior of proteins, and the broad topic will help activate prior knowledge.  
In this ionic and covalent compound worksheet, students investigate the properties of three unknown substances in order to determine if they are ionic or covalent compounds. They write conclusions about their results.
Within this PowerPoint are the instructions for drawing electron dot structures and an explanation of how ions are formed. Several learning check slides are provided, along with the answers. This presentation is a compact, but compatible tool for teaching about covalent and ionic bonds. Your chemistry scholars will increase their understanding as you walk them through it.
Course identification information is included in the upper left corner as well as within the title of this worksheet. If you overlook or remove that information, you are left with a tremendous college biology assignment. There are only four problems to address, but each occupies at least an entire page. The first deals with ions, amino acids, and cell organelles. The second encompasses enzyme action. The third questions the structure of the cell wall in relation to enzymes. The fourth is an analysis of macromolecule structure. 
College-level biologists describe ions and van der Waals forces. They identify parts of amino acid chains on diagrams and describe the chains in a checklist. In a second section, learners compare prokaryotic to eukaryotic cells and then match organelles with their functions or characteristics. Finally, they mark portions of a sequence of amino acids that are expected to be transmembrane regions. This is an ideal assignment to give as a unit review.
Students discuss nutrition and how to make better choices with food. In this algebra and nutrition lesson, students discuss the way the body process food and the importance of nutrition for our cells. They discuss calories, fats and serving size of a normal day intake.
After giving basic details about the properties of carbon, some of the common functional groups and molecules are featured. There is some information about specific functions and impact on the human body. The diagrams are helpful and could be used in any individual lesson on this topic. This presentation would also be a great review starter.
Students investigate foods. In this biology lesson plan, students will conduct testing on different types of foods as they learn about different molecules that make them up. Students will also learn about the shapes of the molecules.
In this Lewis structures worksheet, students review the rules for creating Lewis structures and then practice drawing Lewis dot structures. This worksheet has 17 problems to solve.
As amazing as James Bond is, the surface tension of water does not allow him to walk on it! In this series of little lab activities, physical scientists play with the properties of water due to the hydrogen bonds and resulting polarity. They float a paper clip on the surface, compare oil and water, experiment with evaporation, and think about why water expands as it freezes. Background information, materials, and a challenge are all provided. Lab groups should put together a report of what they learn.
Students explore the polarity of a water molecule and how it affects the properties of water. They explore separation of water and why it occurs, then make predictions regarding separation based on the properties of the liquid.
Students conduct a cross link of a ploymer and observe the changes that occur. These changes would be the physical properties that change and the temperatures would vary. Each group using the cross-linking creates a polymer known as Silly Putty.
In this National Chemistry Olympiad test, junior chemists answer eight problem solving questions on a variety of topics. These include calculating molarity of solutions, determining rates of reactions, calculating decay and discussing topics such as electrolysis.
