For the Shaefer-Fulton endospore stain method, the working solution of safranin is made by combining 10 mL of stock solution with 90 mL of distilled water. If you need to produce 1,046 mL of working solution, how many grams of safranin O will be required to make the smallest batch of stock solution possible? • Report your answer in grams using standard decimal notation rounded to two decimal places. • Include trailing zeros. • Do not include the units in your answer 。 If your answer is 100.105 g it would be reported as 100.11 。 If your answers was 100.203 g it would be reported as 100.20
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 you will use student outcomes to inform future instructional decisions. 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…
