Here is a thorough lesson on safety in the chemistry lab. Chemists review a detailed list of safety rules, draw the layout of the laboratory area to include emergency equipment, identify hazard warnings, and consult the MSDS in order to address a hypothetical chemical accident. Instructor's notes and a student lab sheet are provided in this well-written and vital lesson plan.
Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary structures: cell membrane, nucleus, chloroplast, cell wall, mitochondria, vacuole, and possibly flagella or cilia. Bonus activities include causing plasmolysis in plant cell, and separating plant pigments via chromatography. This is an A+ resource!
There are 66 objectives to be covered by upcoming chemists if they complete this two-chapter assignment. It encompasses all of the information needed to deal with covalent bonds and molecular geometry. Colorful diagrams display the molecular orbital structures. Charts are used to compare them. Practice problems and vocabulary definitions abound!
The 2009 version of the first part of a national chemistry competition is posted for your use with olympiad hopefuls. Test takers deal with 60 multiple choice questions covering an entire year of chemistry curriculum. Use this to practice for the competition or to prepare for a final exam on behavior of gases, properties of metals, chemical reacitons, pH and titration curves, ionizaton energy, molecular geometry, and more!
The National Chemistry Olympiad exams are comprehensive tests covering an entire year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your general chemistry class. This particular part of the three-part exam consists of 60 multiple choice questions. Read through it before assigning to make sure every question is relevant to your curriculum. As a bonus, you will find an answer key attached.
Sixty multiple-choice questions test on a variety of first year chemistry subjects. In order to succeed, exam takers must be competent with properties of elements, stoichiometry problems, gas laws, bond dissociation, and types of reactions. A page is provided that displays a comprehensive chart of abbreviations and symbols, constants, and the periodic table. Also, an answer key is provided for teachers. This is a top-notch exam!
As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of chemistry curriculum. Topics include, but are not limited to pH, molecular geometry, bonding, behavior of gases and solutions, phase changes, and chemical reactions. Use this as a final exam or as a practice for those who want to enter the nation-wide challenge.
Peer review of science laboratory reports? You bet! First, learners work in pairs to review a scientific article. Then they trade lab reports for peer review. Guidelines are described to help you smoothly lead them through the process. The end result, is the publishing of a classroom scientific journal! Consider doing this lesson well before your science fair so that their project reports are written by experienced and peer-critiqued young scientists!
What role did astronomy play in the liberation of France during World War II? Bring literacy and history into science with a cross-curricular lesson that examines the importance of weather stations and moon phases in the invasion of Normandy. After completing an engaging reading from a science journal article, middle schoolers answer a series of reading comprehension and analysis questions. The lesson would work great while teaching moon phases to help answer the question, "Why should I care?"
Chemists consider a situation in which an ethanol producer needs to determine how much to add to t-butanol to prevent freezing during transport. They work in the laboratory to obtain the freezing point depression constant for the t-butanol. They graph the temperature changes and answer questions on the provided lab sheet. This is an outstanding application of freezing point concepts to a real-life scenario.
Chemistry students review the trends found in the organization of the periodic table by completing this worksheet. They determine which of the given atoms has the largest ionic radius and which is the most electronegative. This worksheet has 6 matching, 4 true or false, 10 fill in the blank, and 2 problems to solve. It is neatly formatted and pertinent to any general chemistry curriculum.
In "The Nature of Covalent Bonding," chemistry hopefuls demonstrate an understanding of various types of covalent bonds, electron configuration, and resonance structures through fill in the blank, true or false, and matching questions. They complete the worksheet by drawing three electron dot structures of compounds.
National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers an abundant array of topics and skills and it requires both critical thinking and problem solving to complete. An answer key is provided for your convenience.
Dazai Osamu’s short story, “A Sound of Hammering” is the focus of a three-day investigation of modern Japanese literature and life in post-World War II Japan. The events in Osamu’s story mirror those in his own life, and give a verisimilitude to the tale. Pre-reading activities, plot based and discussion questions, and a QAR worksheet are included in the richly detailed plan.
Introduce your class to the poetry of Lord Byron. This poem, "She Walks in Beauty," is one of his most famous poems. Read through it on the first page, and then walk your class through an analysis using the second page. Readers discuss enjambment, alliteration, and imagery before jumping into a set of six thought-provoking questions.
Connect poetry to a naturally kid-friendly topic: ghosts! Draw on your class's prior knowledge of the paranormal to help them access the classic poem "Haunted House" by Henry Wadsworth Longfellow. After a fun warm-up activity describing ghosts, have the class participate in a collaborative reading of Longfellow's poem before writing their own spooky poem. A must-use lesson for any ELA classroom around Halloween time!
Students conduct experiments with plants. In this photosynthesis lesson, students examine plants under different types of lights. They calculate the amount of dissolved ocygen concentration and compare it to the formula for photosynthesis. Students create a graph of their data.
Here are the instructions for leading your advanced chemists though the process of measuring the nonvolatile components in a sample of paint. No student handout is provided, so you may want to create one based on the procedure explained. This is a terrific activity for teaching chemists how safely handle volatile materials or for calculating percent mass.
A very neat worksheet has been produced by Pearson Education, Inc. for use in a general chemistry class. The first nine questions are fill in the blanks for a paragraph about types of bonds and electronegativity. Five true-false questions and five matching descriptions follow. This would make an ideal pop quiz!
