Collection of Chemistry labs. Topics include the atom, formulas and equations, physical properties of matter, periodic table, chemical bonding, properties of solutions, kinetics and equilibrium, acids, bases and salts, and oxidation and reduction.
Students will have the opportunity to gain a hands-on approach to safety in the laboratory. Included in this experiment is a list of the chemistry department laboratory safety rules to act as a guide for answering questions. Students will locate the safety items in the laboratory and draw a layout. They will also have the opportunity to try out the safety devices in the laboratory.
Students will become familiar with Material Safety Data Sheets (MSDSs) and will extract data relating to the hazards of various chemicals that they will be using in upcoming experiments.
Density and Measurement: calculate the density of known and unknown solids and liquids by measuring the mass and the volume of the objects with lab instruments.; measure liquid volumes by pipetting into containers; weigh objects to six significant figures on an analytical balances.; measure the volume of irregular shaped solid objects by liquid volume displacement.
An activity that allows students to investigate some of their own questions on acids and bases. For a description of how to encourage students to ask questions that can be answered by experimentation check out Inquiry with Anything at Curriki. An added bonus is a link to the Nature of Science.
• Students try to dissolve five different substances in water.
• Students determine the relative solubility of the substances.
• Students compare the physical properties of substances with the similar solubility.
Chemical or Physical Change - let the students decide. Students may be given the full step by step procedure, or perhaps allow for more of a disovery / inquiry based approach, prompting with "what should we do next to determine if this is a chemical or physical change?"
