Innovating Science® Distance Learning: Acids, Bases and the pH Scale 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 base (0.1M NaOH) 5mL Methyl red, 0.02% 5mL Phenolphthalein, 1.0% 5mL Household ammonia 5mL Filtered water 5mL Unknown solution #1 5mL Unknown solution #3 1 pkg Wide-range pH test strips

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. Kit Includes: 4g Aluminum pellets 4g Silicon pellets 4g Sulfur pieces 6 Magnesium pieces 20mL Hydrochloric acid 1.0N 14 Test tubes 2 Nails 1 Plastic scoop
4g Carbon pellets 4g Zinc pieces 6 Copper pieces 5g Sodium bicarbonate 20mL Copper (II) chloride 4 Pipettes 6 Plastic cups, 5oz
