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.

Can I please get help with this graph, if you could show exactly where it needs to pass through please.

16 Report Sheet Basic Laboratory Techniques 9. (a) Using the defined freezing and boiling points of water, make a plot of degrees Fahrenheit ... degrees Celsius on the graph paper provided. (b) Determine the Celsius equivalent of 40 °F_using your graph. The relationship between these temperature scales is linear (that is, it is of the form y = mx+b). Consult Appendix C regarding tio relationships and determine the equation that relates degrees Fahrenheit to degrees Celsius %3D (c) Compute the Celsius equivalent of 40 °F using this relationship. otoo niwallo od tuo m mes be od orb o ela

Based on the information given, identify the most significant error in the preparation of Graph 2.     A)  The title appears in a font which is too small.   B)  The best-fit line does not intersect any data point.   C)  There is wasted space on the graph.   D)  The x-axis scale divisions are uneven.

Make a dilution series to get to 1:100. Start with making 1:10 dilution by adding 1mL of sample and 9mL of diluent, now continue the series to get to 1:100

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?

Design and construct a data table. Be sure to give the table a title.

Answer the questions using one of the words or phrases from the following list. We suggest that you copy and paste answers as it avoids mis-spellings and typos. Accuracy Precision False positive False negative Detection limit Blank Linear range Spike Limit of quantitation Internal standard Please provide the terms for each definition If a patient does not have COVID, but a test results says that they do? How close your experimental result is to the "true" answer? When you run an unknown and then repeat the analysis after adding a known amount of analyte? When you run a solution known to have a zero concentration of your analyte? The lowest concentration of an analyte which can be reported with an accurate concentration? If a patient does have COVID, but a test results says that they do not? How close multiple sample replicate results are to each other?

Categorize each as a determinate or an indeterminate error and further classify determinate errors as instrumental, method or personal. a) An unknown sample being weighed is hygroscopic. b) One component of a mixture being analyzed quantitatively by GC reacts with the column packing. c) A radioactive sample being counted repeatedly without any change in condition yields a slightly different count at each trial. d) The tip of the pipet used in the analysis is broken. e) In measuring the same peak heights of a chromatogram, two technician each report different heights.

Jack measured the mass of an empty evaporating dish and watch glass, and weighed approximately 0.5 g of an unknown solid into the evaporating dish.  He then followed the procedure for Lab Exercise 5, and collected the rest of the data in the table below.  Please note that row letters correspond to those found on the data sheet that you will use in lab.  You will need to refer to this data to answer Questions 13 through 20: A Mass of empty evaporating dish + watch glass 65.362 g B Mass of dish + watch glass + initial solid 65.864 g C Mass of dish + watch glass + carbonate 65.705 g D Mass of dish + watch glass + chloride 65.716 g  What was the mass (in grams) of the unknown solid that Jack used in his experiment.  Type the numerical answer only in the box below (no units!).  Report your answer to the correct number of significant figures.
