Use the Areas of Similar Polygons Theorem to calculate how much material will be required to make the cover for the new pool. 6. A safe amount of chlorine in pools must be strong enough to kill bacteria but not so strong that swimmers' skin and eyes are irritated. Your target is 1 milligram of chlorine per liter of water. a. The Olympic-size pool is 3 meters deep across its entire length. Calculate volume of the pool in both cubic meters and liters (1 cubic meter = 1000 liters). b. How much chlorine (in kilograms) is needed for the Olympic-size pool? c. Explain how you can use similarity to calculate how much chlorine is required for the new pool. d. How much chlorine (in kilograms) is needed for the new pool? Geometry Performance Task 4 Copyright © Big Ideas Learning, LLC All rights reserved.

How can you use technology to enhance teaching and learning in a 5th grade classroom for a lesson on mixing substances based on the below standard and learning objective? (Optional: Use the SAMR model to explain the technology integration strategies you plan to use.) Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.

Instructions You are required to produce a short lab report using the information given in the accompanying document, ‘Lab report assessment_student data’. This document introduces an experiment, and also provides a set of experimental data for this experiment. You are required to use this data to perform steps 8 and 9 of the procedure. This includes calculations of a particular value, and then comparison to the true value. Consider any experimental errors when comparing calculated values and true values. Your report should be between 300 and 500 words (including all table contents and titles of tables and graphs). Your lab report should consist of three sections only: • Experimental • Results and Discussion • Conclusion You do NOT need to include an introduction section. Your experimental section should be written in appropriate lab report format, (passive voice, 3 rd person, in paragraphs). Your results and discussion section should contain the data presented in table format, and…
