Attention Teachers!!!

Materials Needed for Video Conference Activities:



**Experiment: How Does an Epidemic Spread?**

Small cups (Dixie) 15 ml water in each cup vinegar or ammonia cabbage water (red) or phenol (red) thaylene
 * Materials:**

Protective eye glasses Laytex gloves


 * Teacher directions** (to be done before the kids come into the room).


 * 1) Number all the cups
 * 2) Put ~15 ml water in each cup, except one
 * 3) The lone cup gets vinegar (if you are using cabbage water) or ammonia (if you are using phenol thaylene)
 * 4) Assign a cup number to each student


 * Student directions:**
 * 1) Separate students into groups of 4 each
 * 2) Each student chooses another student in their group with whom they will combine liquids. You may only exchange fluids at your own table one time throughout the experiment.
 * 3) Now empty all of your solution into the other person’s cup. Empty them back and forth several times to make sure the solutions are thoroughly mixed. Divide up the solutions evenly in each cup. Record that person’s name beside your name on the data sheet.
 * 4) You will exchange three more times with three different students from different groups. Be sure to mix the solutions thoroughly each time and record the name of the contact.
 * 5) Return to your original tables. Each student will read out the names of their four contacts. Each person will record the names of everyone else’s contacts. Everyone will have a complete list of everyone’s contacts.

Now comes the moment of truth. You are ready to be tested to see if you are infected.

· Solution turns red!! – **You have the disease** · Solution turns yellow or clear – **You are not infected**
 * Teacher directions:**
 * 1) Add a drop of phenol thaylene or several drops of cabbage water to each solution.

Empty the contents of all the cups safely.




 * Directions for “Marco Polio” **

**Objective:** One student makes his way through the room avoiding touching any students who have polio.

1. Clear an open spot in the room.

2. Choose 5 students to position themselves in stationary spots in the room.

3. Blindfold one other student. The blindfolded student must call out “Marco.” The others answer “Polio.” The blindfolded student gauges his path upon hearing the voices of the other students doing his/her best to avoid touching any of the other students.

4. Repeat #3 at least two more times getting to the opposite side of the room without touching anyone. If successful, the blindfolded student does not “get” polio.

Repeat with another set of students.
