Activity B: Rates of diffusion Get the Gizmo ready: Click Reset. Introduction: The Diffusion Gizmo allows you to manipulate five variables: the Wall, the number of x particles in region A, the number of y particles in region B, the temperature, and the Particle mass. Question: How do factors other than temperature affect the rate of diffusion? 1. Choose a variable: Pick a variable to investigate. Which one did you choose? 2. Form hypothesis: How do you think this variable will affect rates of diffusion?

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

Project PART I. Our Carbon Budget A major driver of global climate change is the emissions of greenhouse gases such as CO₂ into the atmosphere from human activities such as the burning of fossil fuels for transportation, electric power generation, manufacturing, agriculture, home heating, and so forth. Global average temper- atures are now slightly higher than 1° C above their pre-Industrial Revolution levels. Damaging sea level rise and extreme weather events (such as the recent wildfires in Canada that led to the unhealthy air in NYC last summer) will become an increasingly major problem around the world if global average temperature rises more than 1.5° C. Scientists estimate that the total additional amount of CO₂ that can be put into the atmosphere without reaching the 1.5° C level is about 51 parts per million (ppm) or approximately 400 Gigatons (Gt). Let's call 51 ppm our carbon budget. In this project, we want to use linear systems of differential equations to analyze the…

It occurs when gases such as nitrogen (N₂) come out of solution in the blood. This can lead to symptoms including joint pain, shortness of breath, and paralysis. Severe cases may result in death. a What type of molecule (ionic, polar covalent, nonpolar covalent) is nitrogen gas? b The liquid medium of blood is water. What type of compound (ionic, polar covalent, nonpolar covalent) is water? c What happens when molecules such as nitrogen gas mix with water? How does this explain the problems we see with decompression sickness?

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.

TRUE OR FALSE __________ 6. Glassware is clean when no water droplets cling to the inner wall of the vessel. __________ 7. When smelling the odor of a chemical substance, fan your hand over the substance toward your nose which should be centimeters away from the substance. __________ 8. An accident as simple as breaking a beaker containing distilled water in the sink does not need to be reported to the laboratory instructor. __________ 9. Students should turn off cell phones, iPads, and other electronic devices during the laboratory class. __________ 10. It is a good laboratory protocol to call other students’ attention when they do not practice good laboratory safety procedures.

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…

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.
