Today the innovation lab visited and showed us the SCIO, "pocket spectrometer" that scans things around us and shows their chemical make up. See the video below about how it works. We talked about our favorite types of apple, and then used an app with the Brix scale that farmers use to see which apple was the sweetest and the most nutritious. Fuji won! We also looked at other fruits and veggies. Most people's favorite part was comparing the nutrition and cocoa content in different types of chocolate. Turns out white chocolate has no cocoa. Didn't stop people from sampling it though!

For the final part of the sound project, we invited people from the Teen Center and the community to decorate foam acoustic panels with fabric to reduce noise in the homework room in a personalized, beautiful way! First we did some testing to get "before" conditions for the homework room. We created the "mini rooms" to model with and without sound panels and compared using speakers, various sound meters on phones, and even our heads. Next we used a sound meter to test sound levels in the homework room in a variety of conditions including silence, small talk, music playing, someone singing or yelling, and a frequency sweep. We also considered whether the sound was coming from inside or outside of the homework room. Creating the acoustic panels...so far we've made over 30!
We've been busy this week! Our data analysis team created graphs and visuals to represent the data. One group worked on creating sound graphs and figuring out which types of sounds created the loudest and quietest decibel readings. We created graphs using the max and average db readings according to time of day to see which days and which time periods were the loudest. Another group created a map of Isla Vista and polled people about which sounds to include on the map. Then they helped create an interactive map with representative sounds at places such as Children's Park, the Habit, the Loop, the Teen Center. A photo of our map in progress is below, the video will be next!
We downloaded and formatted data today, looking over the dates from March to May, the location, time of day, max, min and average sounds. We have over 125 data points from our sound blasts and people collecting it on their own! A big thanks to Saul for help with organizing the data into a readable excel format. Our data analysis team also thought about their original questions and came up with these to look through for the next step:
•What day of the week was it the loudest? •What day of the week was it the quietest? •What time of day was it the loudest? •Where was it loudest? •What caused these different types of sounds? •What source caused the loudest sound? This a touch board activity that make sounds when you touch the word. The sounds are about what the words are for example the beach has a sound of the beach waves. Step 1: materials- touch board
- big sheet of paper - conductive ink pen - conductive paint - conductive string - word cloud image - lipo battery - a speaker Step 2:- print big word cloud heart sheet - fill in important words with the conductive paint/ink pen Step 3: - download word sounds onto touch board - tape touch board to the heart sheet - connect lines to the important words - fill in the lines with conductive ink pen - tie conductive thread to touch board, then tape them onto the lines that are attached to the words you choose *IMPORTANT NOTE!!! don't let the lines touch or else they won't work* Step 4:- Good luck connecting the lines to the words you choose! And thank you for taking you're time to see how we made our project work!! :) Its a twist to a normal bean bag game and fun for kids! It also makes cool sounds.
Step 1: Supplies
Step 2: Draw Characters Draw the characters with pencil on the bean bag stand. Paint them with acrylic paint Step 3: Drill Holes we drilled holes on the places we wanted to hear a sound. We put screws into the holes. for example we put three screws in shrek's face. Step 4: Touch boardwe downloaded mp3 sounds of shrek and then we saved it to the touch board. how to transfer sounds to the touch board available online: http://www.bareconductive.com/make/introducing-the-touch-board/ Step 5: Alligator clipsafter we used alligator clips to connect the touch board sounds to the screws. we also used conductive paint on the top side of the screws. we used conductive paint so that all of the board makes a sound when anything conductive touches it. Step 6: Conductive beanbags you have to use conductive fabric wrapped around the beanbag so that it worked when it touches the conductive paint. Step 7: Connecting you have to plug a battery to the touch board and also a speaker so you can hear the noise. the screws and the touch board were connected by alligator clips. don't forget to test it out before to make sure the sounds are right for each character |
