The figures below show the most common appearance of matter that we recognize. Recall that particles that make up matter behaves in a very specific way that gives the material its distinct property, such as a definite structure or taking the shape of its container. Can you guess which states of matter is being represented by the particle arrangements shown below? Defend your answer. This is most likely a: Because: twinkt.com Figure A twinkt.com Figure B twinkl.com Figure C

INTERACTIVE EXAMPLE The Average Mass of an Element = When a sample of natural silver is vaporized and injected into a mass spectrometer, the results are shown in the figure here. Ag-107 is present in 51.84% abundance. Ag-109 is present in 48.16% abundance. The masses of these two isotopes are Ag-107 = 106.91 u and Ag-109 108.90 u. Use this information to compute the average mass of silver. Percent Abundance -100 60 40 -20 51.84 107 Atomic Mass 109 u Submit Show Tutor Steps

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…
