What is one way that you can stop the virus from spreading so that hospital capacity isn’t reached?
Flatten the Curve: A Chemical Analogy Using Hydrogen Peroxide and Rusty Iron
Chemical analogy demonstrating the utility of social distancing.
How do the number of social gatherings affect the spread of the virus?
Flatten the Curve: An Analogy Using Coke and Mentos
Chemical analogy demonstrating the utility of social distancing.
Explain the effect of the dragon wearing the face mask vs. not wearing the face mask
Lycopodium Dragon Sneeze with a Face Mask
Variation on the lycopodium powder dragon's breath demo showing how face masks can prevent the spread of particulates through the air.
Explain the effect of what happens when a mask is used vs. when it is not used.
Homemade cloth mask blocks base-containing spray and prevents it from changing the color of goldenrod indicator paper. If no mask is in the way, the spray changes the color of the paper. The face image was drawn on the paper with paraffin wax.
Why is it important to make sure you properly wash your hands?
Washing fluorescent "germs" from my hands
A classic hand-washing activity, in which an ultraviolet light is used to show where I missed washing fluorescent pretend "germs" from my hands.
Why do oil and water not mix? How does this analogy relate to COVID-19?
Bottles containing yellow corn oil and water with food coloring can be used to demonstrate density, polarity, and the effectiveness of soap in dispersing oily materials, including the outer layer of the COVID-19 virus.
Explain the benefits of the vaccination based on this demonstration.
The purpose of this demonstration is illustrate that vaccination can protect a population against illness.
What happens when people do not get vaccinated?
The purpose of this demonstration is illustrate that vaccination can protect a population against illness.
What is the difference in spread of illness when people are protected (masks, social distancing, vaccines) vs. unprotected
The purpose of this demonstration is illustrate that vaccination can protect a population against illness.
How is the spread of COVID-19 explained by an exponential growth chain reaction?
A domino-like chain reaction cascade, only using ten-brick LEGO stacks connected to a surface with duct-tape hinges for easy reset. The cascade can represent a variety of things: nuclear fission chain reaction, spread of disease, transmission of information, etc. By supporting a stack, some of the chain reaction cascade is stopped. Among other concepts, this is reminiscent of using public health measures to help prevent the spread of disease.
