Name Date Chapter Performance Task (continued) 8 5. The new pool also needs a cover. 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.

What will be the probable effect if you kept the crucible completely covered during the entire heating and cooling processes? Would your calculated percent water in the hydrate be high, low, or unaffected? Explain. 3. If 2.752 g sample of Ca(NO:); XH;O is heated to constant mass, the residue weighs 1.941 g. Determine the value of x and the formula of the hydrate.

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…

Procedure 1. A crime situation is presented to you. You need to solve the crime by using your senses and given information. 2. Fill in the investigation report correctly. CRIME SCENE A man is found dead in a vac ant lot near his work place. In the crime scene, the SO cO collected different pieces of evidence including two pieces of cloth tainted with unknown stains. The police are hoping that through these pieces of evidence they could find the culprit criminal. or Cloth A Cloth B Pieces of evidence Data and Result Crime: Date: Piece of collected evidence:_ OBSERVATIONS: Cloth A Cloth B Final Findings: Questions 1. Which of the cloth A and cloth B can be used as possible source of evidence in the crime? Why? 2. Which property of matter did you use in making your observation?

Experimental Procedure Graphing 1. Obtain a 100 mL graduated cylinder. Add 10.0 mL of the liquid to be analyzed to the cylinder and obtain the mass. Write this mass on the results table. NOTE: it does not have to be exactly 10.0 mL. If something other than 10.0 mL is added, note that change on the data table. 2. Continue to add 10mL portions of liquid to the cylinder and obtain the mass each time. Write the cumulative volume, making sure to measure your total volume accurately with each addition, and its corresponding mass in the table. DO NOT EMPTY THE CYLINDER BETWEEN ADDITIONS OF LIQUID. 3. Dispose of the liquid in the appropriate container in the fume -hood. 4. Draw a graph of mass versus volume. Use the guidelines set forth in the example. Make sure the graph takes up as much of the graph paper as possible     Graphing   Increments For the X-axis: Highest X value –Lowest X value/ #of boxes(15) =____ Round up to____   Increments For the Y-axis:Highest Y value –Lowest Y value/# of…
