Introduction
Hello, scientists!
We have been talking about sound. We've talked about what sound is, how it is made, how it travels, and how it is measured. We have learned that each sound creates a vibration. The sound travels to the little thing in our ear that looks like the top of drum. A message is then sent to your brain and you hear the sound!
Task
Oh, no! You are lost outside in the wilderness miles and miles away from buildings, roads, and people. The only way to save yourself is to listen to all the sounds in nature. The more sounds that you listen to and identify, the closer you will be to finding your way back home. You must also estimatei how quiet or loud the sound is in decibles.

What is a Sound?
Process
1.Get your science notebook. Go outside in nature.
2. Sit quietly and listen to all the sounds around you.
3. Write down ALL the sounds that you hear.
4. Try to name the sound you hear (example: leaves falling from the tree).
5. Estimate the volume of the sound using benchmarks already disscused (how many decibels).
Evaluation
You will present your finding to the class. As a class, we will decide if each person was able to find their way back after being lost. You must have at least ten sounds written down in your science notebook.
Decibels should be within an appropriate benchmark.
Conclusion
You have (hopefully) successfully found you way back home again! You are now sound experts! Now that you are a sound expert, always be listening. There might even hear sounds you've never heard or noticed before!
