Explain your rationale for using the summative assessment (below) from the lesson plan on mixing substances in a 5th-grade classroom based on the below standard and learning objective, including how it aligns with the learning objective.  Summative Assessment  Summative: Components of the Lab Report Purpose: The student should clearly state the purpose of the experiment, which is to determine whether the mixing of two or more substances results in new substances. Procedure: The student should describe the steps they took to conduct the experiment. This includes the substances they chose to mix and the safety equipment they used. Observations: The student should record any observable changes that occurred when the substances were mixed. This could include a color change, the formation of a precipitate, or a change in temperature. Conclusion: The student should state whether a new substance was formed based on their observations. They should also reflect on their accuracy in…

Below is a simple set of weights obtained while immersing potato slices in various sugar solutions over 30 minutes. I need help calculating all of this for a 30 min period  a. For each solution, calculate the rate of weight change over this 30-minute period. Show your work in the space below. Once you calculate these rates - fill in the blanks below and then add these answers to your Canvas exam. Write your answer in standard notation and use  3 digits past the decimal point - e.g. 0.005, 0.030. (Note that the last zero in an answer is considered to be a digit). Show your work in the space below.  0.0 M sucrose = _______  _____________ g/min 0.4 M sucrose = _______ ____________ g/min 0.6 M sucrose = ________ ____________ g/min 0.8 M sucrose = ____________________ g/min 1.0 M sucrose = ________   __________ g/min Using the osmosis data in the question above, determine the percent weight change for each sucrose solution and fill in the blanks given below and then add these answers to…

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…

Assuming that an experiment's results are 10.1, 10.4 and 10.6, find the mean, the average deviation from the mean and the standard deviation. You can use Excel to verify your calculation. Use the editor to format your answer

New employees at Avondale Industries’ unmanned systems production line in Denver, CO, participate in employee training under the direction of the training and development department, but the line managers conduct the actual training. During the last two trainings, the line managers cut the sessions short and explained that the employees would receive better training while working on the production line. The trainer responsible for the program understood the line managers’ viewpoint about developing skills used on the line but needed them to see that training should provide more than just developing those specific skills. Which of the follow statements best explains why training should provide a longer-term view than just teaching line workers the skills needed to perform satisfactorily in their current jobs?     Giving line workers expanded training helps them understand more than specific skills; it also helps them become more confident contributors.   Training with a…

Provided are spectra for a compound with molecular formula CgH100 Part A) Give the degrees of unsaturation Part B) Identify the peaks that are associated with specific bonds of the structure and list the corresponding functional groups that the specific bonds belong to. Re- create the example table below that organizes this information. Use the wavenumbers that are already labeled on the spectra. Example table: wavenumber (cm-1) Corresponding Bond Type Corresponding Functional Group C(sp3)-H N-H 2978 3300 Part C) Draw the structure and clearly indicate which hydrogens correspond to which signals in the HNMR spectrum ONLY. The signals are already labeled A-D on the HNMR spectrum. Match the hydrogen labeling (HA, HB, etc.) on your drawn structure to the signal labeling provided. 4300 3320-2872 2951 3006 3003 2001 alkyl amine 1613 1510 1000

Why is it that the method used to attack a problem is an important as the answer to the problem itself?

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.

A chem....rking as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of tetrahydrofuran, chloroform, ethanolamine, diethylamine, and pentane. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density tetrahydrofuran -1 0.89 gmL -1 1.5 g•mL chloroform ethanolamine 1.0 g•mL¯ diethylamine - 1 0.71 g•mL pentane - 1 0.63 g mL Next, the chemist measures the volume of the unknown liquid as 1062. cm° and the mass of the unknown liquid as 1.08 kg. Calculate the density of the liquid. Round your answer to 3 significant digits. 1 g•mL Given the data above, is it possible to identify the liquid? yes no tetrahydrofuran chloroform If it is possible to identify the liquid, do so. ethanolamine diethylamine pentane

Choose the one correct or one incorrect statement regarding filtration:      gravity filtration uses a Buchner funnel, filtering flask and negative pressure      filter paper should be wet with solvent to seal it to the funnel before filtering      the solution collected in the filtering flask is called the residue      vacuum filtration is most often used to remove impurities from a solution      the solution to be filtered should completely fill the top of a Buchner funnel

You measure 35 turtles' weights, and find they have a mean weight of 72 ounces. Assume the population standard deviation is 3.1 ounces. Based on this, construct a 99% confidence interval for the true population mean turtle weight. Give your answers as decimals, to two places ounces

You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.
