Benz Microscope Acids, Bases, and the pH Scale Small Group Learning Kit. 

HS-PS1-3. Plan and conduct an investigation to gather evidence to compare the structure of sustances at the bulk scale to infer the strength of electrical forces between particles.

PS1.A: Structure and Properites of Matter

• The structure and interactions of matter at the bulk scale are determined by electrical forces within and between atoms.

PS2.B: Types of Interactions

• Attraction and repulstion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects.

Wether distance learning or in person, this small group activity kit will help students 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.

Manual covers Introduction, Objectives, Materials list, Safey, Procedure, Analysis, Answer Key and Safety Data Sheets. Enough materials for 2 groups of students are included. Perfect for distance classroom learning and small group learning situations such as home school, science clubs, scouts, and more. SKU BZ8703.
