In the following sub-questions, use your book and notes to generate an argument for each model of light. Remember, on the first day of class we discussed that argumentation requires: ● a claim (which I've given), • evidence (which you should look up in the form of data or scientific principles) and reasoning that connects the evidence to the claim (which you should generate from your understanding so far).
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…

The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing. It is important to consider what the experts say, but to also evaluate their statements. We will start with the scientific method. I want you to outline the scientific method from what you have been taught in previous classes. You can list steps, parts, process, short descriptions, whatever. If not taught in previous classes, then you will make your best guess about it.
FINAL Experiment 1- January 2021_-789644623 - Saved Layout Review View Table A friend of yours went panning for gold last weekend and found a nugget that appears to be gold. With your newfound scientific prowess, you set out to determine if it is really gold. Your tests show that the nugget has a mass of 7.6 g. Immersing the nugget in water raised the volume from 7.22 mL to 8.06 mL. The density of gold is 19.32 g/cm3. What will you tell your friend? acer
