Define the Problem:
My partner and I chose the topic Sound waves. Sound waves are a pattern caused by energy traveling through a medium as it moves away from the sound source. The source can be an object that causes vibration, like a telephone, or our own vocal chords. The vibration moves the particles in a medium, those particles then disturb the other particles next to them, and so on. This disturbance then creates a wave like pattern that moves outward. We'll be teaching this and more about sound to third graders in our High Tech Village during their science festival.
Research:
For research in our topic we began with figuring out what sound waves were. We watched YouTube videos about sound, and that helped us decided that we wanted to do our project on compression waves and what they look like. With that done we looked up possible experiments we could do with the third graders. There was such a wide selection it was hard for us too choose, but we thought the best way to visually represent compression waves was to model it with a slinky. From there with our interactive experiment chosen we wanted to focus on what sound actually looked like so we researched on amplitude, nodes and anti-nodes, wave lengths, their purposes and what they all meant.
Design:
- Accumulation of Notes:
- Presentation Layout
For our in class presentation we started off with an introduction asking students if they think we can see sound. If so then where do they think we can see it and some examples. From there we passed out materials for out engaging activity. We had the students cover the top of a cup with a balloon to make a smooth surface. Then placed some rice on top. We went around to the different tables using two metal objects and hitting them together. As the students observed the rice moving around on the surface, we asked students to try hitting different objects together or find another method to move the rice indirectly using sound. Once that was done we collected the materials and passed out the slinky's and rope for our explore section. We showed the students how to visualize longitudinal waves and transverse with the materials. After that, we explained the different components of longitudinal waves and transverse waves. As well as what they are and where you see them. Lastly, we quizzed the students on the topics we covered through out the presentations.
Present for feedback:
Through out the presentations, students were tasked with writing feedback forms for the presenters. This is a list of feedback we got:
- Make a Vocabulary sheet with definitions of new words you stated through out your presentation
- Give video examples
- Make a mini test for the kids
- Get treats to pass out to the children for answering questions right
- Make a wave worksheet page
- Prepare the first experiment before hand because its hard to set up
Select best Solution:
After revising all the feedback we decided to buy some chocolates to pass out and create a worksheet for them to fill out at the festival.
