MyScience Group 4 - Petar, Ben, Anthony S and Justin  The Yawning Experiment Hypothesis: __** Do people yawn when they hear yawns through yawn wavs by being blindfolded in a dark room.
 * __ Heading: __**
 * __

Usually people yawn when they hear other people yawn so we wanted to know if yawns are contagious when you hear them.
 * __ Observation: __**

The TV show "MythBusters" has already conducted a similar experiment around whether yawns are contagious. This experiment can be viewed by [|clicking here] or by [|clicking here]. The results of this experiment show that yawning is contagious. **__ Question: __** Will the participants yawn when they hear the yawn wavs.
 * __ Background Knowledge: __**

First, we had to create a yawn wav file. We did this using Audacity audio editing software. We collected our wav. files through detailed Google searches. We used Audacity to connect the yawn files to create our big yawn track. We will use this track during our experiment. We will conduct our experiment in a quiet room with the lights turned off and the blinds down. Participants had to wear a blindfold during the experiment whilst lying down on the floor. We then put headphones on the participants so we had no background noise and so they could hear the yawn track.
 * __ Experiment: __**

Headphones yawn wav files girls and 4 boys from year 6 a room to do experiment in. computer yawn track (created using Audacity - See demo below) media type="file" key="Yawn Track.wav"
 * __ Equipment/Materials: __**

That people will yawn when hearing the yawn track.
 * __ Hypothesis: __**

We will get 10 people from year 6 to listen to some yawn wavs through some headphones on the computer. We will record how many times they yawn in 5 minutes using a timer. We will record our results on a table.
 * __ Procedure: __**

Petar:I am the group scribe. Ben:Was in charge of getting the people\ Justin:was the recorder. Anthony:he was in charge of time keeping.
 * __ Our Group Roles: __**
 * __ Results: __**





The table shows that each participant and how many times they yawned. Graph A shows a visual of the same information on the table. We can clearly see that boys yawned more during our experiments. This can also be seen in Graph B when we do a gender breakdown.
 * __ Analysis: __**

From our test, our group concluded that when people hear a yawn, it is more likely that a boy will yawn rather than a girl.
 * __ Conclusion: __**

Other ideas for future experiment could be:
 * __ Further Investigations: __**


 * Use more participants from both genders.
 * See if age makes a difference when hearing a yawn
 * Using different wave file (possibly more) to be and sound more realistic (at the end, it made people laugh as they thought the yawn sounded like a bear).

Our group would like to thank all the participants, the group (Ben, Justin, Anthony and Petar), our class teacher as well as Mrs Forbes and Mrs Alford.
