Fourth Grade, Pandemics – COVID-19 Science Projects (2 results)
Humanity has faced pandemics since the beginning of time. The twentieth century saw multiple influenza pandemics, and now we are facing a COVID-19 pandemic caused by a coronavirus.
Coronaviruses are not new to humans or even to you. Coronaviruses are a family of viruses best identified by the crown-like spikes that cover their surface (corona is Latin for 'crown'). Coronaviruses cause upper-respiratory tract illnesses like the common cold and the 2003 SARS and 2012 MERS outbreaks. In the winter of 2019, a new coronavirus, now officially called SARS-CoV-2, emerged in Wuhan, China. The virus made the jump from animals to humans and causes a disease called COVID-19. For some people, often children and young adults, SARS-CoV-2 causes few or no symptoms. For others it can lead to severe lung damage and even death. The virus can be spread fairly easily, including by people who are infected but display no symptoms, and as a result, we are in the middle of a global pandemic, with nearly all countries in the world reporting an increasing number of infected individuals. Scientists and health professionals around the globe are working hard to rapidly learn more about this new coronavirus and the disease it causes and to prevent the spread of COVID-19.

Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate.

Being sick is no fun, especially when your friends are doing exciting activities that you have to miss out on. Thankfully, common illnesses usually last for just a few days, and then you start to feel better. Why is this? It is thanks to the immune system, which is a group of special organs and cells in your body that constantly work to keep you healthy. In this science project, you will make a simple model to investigate how the immune system defends the human body from common illnesses, and…
