In this lab, students will gain an understanding of the basic differences between the properties of acids and bases, learn the role of hydrogen and hydroxide ions in acidic and basic substances, and comprehend the nature of the pH scale with regards to acid and base strength. Students will examine the effects of acids and bases on several pH indicators, determine the pH of several common household materials, and use the knowledge gained to determine the identity of four unknown solutions. Instruction Manual and enough materials for 2 groups are included.
Kit Includes: 5mL Deionized water 5mL Dilute acid (0.1M HCl) 5mL Dilute base (0.1M NaOH) 5mL Litmus blue, 0.5% 5mL Methyl red, 0.02% 5mL Bromothymol blue, 0.5% 5mL Phenolphthalein, 1.0% 5mL Vinegar 5mL Household ammonia 5mL Soap solution 5mL Filtered water 5mL Vitamin C solution 5mL Unknown solution #1 5mL Unknown solution #2 5mL Unknown solution #3 5mL Unknown solution #4 1 pkg Wide-range pH test strips 2 Reaction trays

Distance Learning: Periodic Table - Nonmetals, Metals and Metalloids
During the nineteenth century, a Russian chemist name Dmitri Mendeleev began constructing a table of the elements. The result, called the Periodic Table of the Elements, is an organized classification of chemical elements based on certain properties of each element in relation to other elements. In this lab students will learn about three different categories of elements—metals, nonmetals, and metalloids. They will examine the physical properties of several elements and test their chemical reactivity, then use their results to classify each of the tested elements as either metal, nonmetal, or metalloid. Kit contains an Instruction Manual and enough materials for 2 groups of students.

Distance Learning: Kidneys and Blood Filtration
Learn the role of the kidney in blood filtration and waste removal along with the many tasks performed by the functional units of the kidney, called nephrons, as well as nephron structure. Students will create an artificial kidney model to filter a simulated blood solution, and will be able to visually determine if filtration of the simulated blood occurred. They will also perform chemical tests on the resulting filtrate to detect any possible waste material that may have been removed by the artificial kidney. Kit contains an Instruction Manual and enough materials for 2 groups.
Kit Includes: 10mL Simulated Unfiltered Blood 250mL Deionized Water 2 pc. Dialysis Tubing 2 Plastic Cups 2 Pipettes 4 Salt Test Strips 4 Urea Test Strips

Distance Learning: Forensic Chemistry of Unknown Substances
When collecting evidence at a crime scene, investigators may encounter substances that they are not able to identify in the field. These substances will be sent to a crime lab, where a forensic scientist will work to analyze and identify them. In this experiment, students will take on the role of a forensic scientist and use their observation skills, senses, and a series of chemical tests to determine the identity of two mystery substances. Kit contains an Instruction Manual and enough materials for 2 groups of students.
