In this lesson, students will find the location of operation keys on their calculators, use order of operations on a calculator, input scientific notation into a calculator, and use a scientific calculator or graphing calculator to perform calculations.
In this lesson, students will maintain a fermentation experiment and set up gas collection equipment in the lab.
In this lesson, students will analyze the results from a fermentation experiment and set up gas collection equipment in the lab.
In this lesson, students will identify common types of measurements made in the lab and the tools used to make those measurements as well as perform measurements in the lab implementing proper use of the metric system and significant figures.
In this lesson, students will distinguish between accuracy and precision and explain the reliability of digit in a number. Then they will read lab equipment and report to correct number of significant figure while identifying the uncertain unit and round to correct number of significant figure.
In this less, students will list three (3) common measurement systems used in high schools as well as common unit conversion equivalencies and be able to use dimensional analysis to convert between units.
In this lesson, students will write the generic format for an acid base reaction and then identify the salt on the product side of an acid base reaction. Students will write the definition of a conjugate acid or base and pick out the conjugate base and conjugate acid from and acid base reaction before matching the acid/base and conjugated base/ acid pair when given an acid base reaction.
In this lesson, students will explain how a digital pH meter works before calibrating a Digital pH Meter while following SOP for calibration. Then they will test the pH of a solution while following SOP for pH meter testing.
In this lesson, students will explain the plot of pH vs. volume to show buffering capacity of a solution and then graphically represent the difference between a buffered and un-buffered solution.
In this lesson, students will state/ recall the components of Molarity, Molar Mass, and the conversion between mL and L and then write a generic protocol for preparing a buffer, given a buffer table.
In this lesson, students will:Use the subscripts in a chemical formula and identify how many of each atom are present. Write out the dissociation of water into, H+ and OH- .Name and identify H+ as a proton, H3O+ as hydronium, and OH- as hydroxide. Identify the key difference between Lewis Acid Base and Bronsted Lowry Acid base Definition.Identify three (3) common laboratory acids and three (3) common bases used in the lab.Show that the acids identified increase [H+] or [H3O+] and the bases increase [OH-] in solution.
In this lesson, students will name the most common methods for determining solution pH and then explain how to use as pH meter based on standard operating procedures and explain the process of calibrating a pH meter.
In this lesson, students will use the skills and knowledge learned over the course of the pH unit to prepare and test a buffer given a scenario similar to what might be asked of in a lab job.
In this lesson, students will explain what a buffer does and how a buffer works. They will use an analogy to explain buffering capacity and name common laboratory buffers and biological systems buffers.
In this lesson, students will write a brief explanation of what a pH indicator does when introduced to various solutions and use red or blue litmus paper and pH paper to determine if a solution is acidic or basic.
In this lesson, students will:Recall/ State definition of pH.Know what a log base 10 scale is and explain the magnitude difference between numbers in the scaleUse the log10 and anti-log10 function on a scientific calculatorGive the range of the pH scaleIdentify where acids, neutral and bases, strong and weak are on the pH scalePlace common laboratory and household acids and bases on a pH scale
Students engage in learning about all biosafety levels and there importance.
Students learn about Personal Protective Equipment. They discuss theequipment they will be using in class and will practice appropriate use and disposal of theequipment while learning how to properly protect yourself in the laboratory.
Assess students understanding of proper use of PPE, how to use safety equipment in a lab, and the correct way to safely clean up a spill.
In this lesson, student will design and implement their own experiment using the methods developed from the hand sanitizer lab.
