How do diseases spread? Often from one person to another. In this activity, students simulate such an infection. They use clear liquids and walk through a series of exchanges before adding an indicator to see if they're infected. By tracking the sequence of exchanges, students can determine the original pair that were infected. 

 

Use this to learn and reinforce answers to questions such as:

❑  How do diseases spread through a community?

❑  How can you track the spread of disease?

❑  Why is tracking a disease important?

 

Once students try this activity, they can capture their observations using the included Lab Notes or probing questions included in the instructions. 

 

Concepts Addressed

♦  Many diseases spread through contact

♦  Infections can be tracked through a community

♦  Unchecked, diseases spread exponentially
