Pod Color: Green Scientific Argumentation - Using Claim, Evidence, Reasoning (CER) The Claim is a conclusion statement that answers a specific question. What can you conclude? Was the hypothesis supported? The Evidence is your data that supports the claim (tables, charts, graphs, observations). What facts led you to make the claim? In most cases, you will summarize data collected in an experiment, or share specific details from an article. The Reasoning is a detailed explanation for why the evidence led you to make the claim. It may also include an explanation of the scientific concepts that are relevant to the claim. Often reasoning can be phrased as an “if-then” statement ties the claim and evidence together. 1. View the data on the next page and determine what claim is being made. Some studies suggest that young children are less likely to get infected with the coronavirus. The hypothesis was supported with one potential reason is that kids younger than 10 may have lower leves of ACE2 – a protein that the coronavirus uses to break into host cells – in their respiratory tracts than older children and adults. 2. What evidence is the graph showing? Summarize. The graph indicates that ACE2 levels, measured as the percentage of RNAs from ACE2 relation to total RNAs, in the nasal pessages are lower in young people than older. 3. Create a statement that links the evidence to the claim (reasoning). Research suggests that children younger than ages 10 to 14 are less likely to become infected with the virus that causes COVID-19. According to the Harvard Health Publishing, Most children who becamme infected with COVID-19 have no symptoms, or they have milder symptoms such as low-grade fever, fatigue, and cough the amount of virus found in children – their viral load – was not correlated with the severity of their symptoms. In other words, more virus did not mean more severe symptoms. Finding high amounts of viral genetic material – these studies measured viral RNA, not live virus – in kids doesn’t not prove that children are infectious. However, the presence of high viral loads in infected children does increase the concern that children, even those without symptoms,could readly spread the infection to others. www.biologycorner.com www.biologycorner.com
