1. Masks Against COVID-19
2. Terms to Knowhow well something works; how effective something is the virus that causes COVID-19 diseasea family of viruses characterized by a crown of spikes on the outside; includes respiratory diseases like MERS and SARSdifferent forms of a virus that occur as a result of random mutations a disease outbreak that has spread over several countries or continentsprovides a trigger to help the immune system build immunity to a diseaseWord BankcoronavirusefficacypandemicSARS-CoV-2vaccinevariant
3. Understanding COVID-19Coronaviruses are a type ofvirus with a crown of spikeproteins sticking outThere are many types,including SARS, MERS, and viruses that cause coldsSARS-CoV-2 is the specific coronavirus that causesCOVID-19COVID-19 causes respiratory symptoms but can also harm other parts of the bodyMore than 4.5 million people have died from COVID-19 worldwide
4. Think About ItHow can wearing a mask help stop the spread of viruses?Are some types of masks better than others? Explain your answer.What are some steps you could take to protect yourself and your community from COVID-19?
5. COVID-19and CDCCOVID-19 spreads through respiratory dropletsMasks block respiratory droplets produced while breathing, talking, coughing, and sneezingMany COVID-19 cases are asymptomatic; infected people may not know they are spreading the virusStaying at least 6 feet apart also helps slow spread
6. COVID-19 and CDCCloth MasksMust use tightly woven fabricNose wires improve fitDisposable MasksSurgical masksKN95 for individual useN95 for healthcare professionalsAdd cloth mask or mask fitter on top of disposable masks to improve fit
7. Think About ItWhat is the primary way that the SARS-CoV-2 virus spreads from person to person?If a person’s mask drops below their nose, what happens to their respiratory droplets?What are some reasons that people might have to choose masks instead of vaccination to protect them from COVID-19?
8. From the Experthttps://youtu.be/1LZZz1yMGvY
9. Think About ItAccording to Dr. Carlson, what are other ways besides respiratory droplets that SARS-CoV-2 can be spread from person to person?What are some problems you have encountered while wearing a face mask that you might want to fix in your design? As new variants of COVID-19 emerge, the efficacy rates of vaccines may decrease. How will this affect communities? How might we respond to this change?
10. Give it a TryCall to Action!Test face masks. Design a better face mask. Share your findings. Why do you think participation is important?
11. Use the Engineering Design Process
12. Give it a Try1. Test Face Masks Get 6 masks made of different materialsLight a candle 6 inches from edge of tableWhile wearing each of the 6 masks:Read a paragraph from a bookSing a verse of a songTry to blow out candleRecord candle observations for each test
13. Give it a Try2. Design a Better Face Mask Use the results of your experiment to design a mask that fits well, is comfortable, and is effective at stopping respiratory particlesTest your newly designed mask
