July 28-August 1, 2014 - Middle School

Summer Camp 2014 Application

Music and Dancing with PicoBoard and Scratch

Music and Dancing with PicoBoards and Scratch July 28 - August 1, 2014

Would you like to create a story with you as the star, interactive art, or a 2D game like pong? Would you like to make and program a musical pickle or potato? Would you like to see how fast you react to a sound or a light? During this week of camp you will use free software from MIT called Scratch to create 2D animations and games. You will use PicoBoards to make digital arts and crafts and food that react to sound, light, and touch. You'll use LEGO WeDo sensors to control Scratch characters and will control WeDo motors, using Scratch programming. For more information on Scratch see For more information on PicoBoards see You will do hands on activities that will introduce you to computing concepts such as repetition (loops), conditionals, variables, and random numbers.

9:00am Pre surveys:
9:45am Ice breaker game - Snowballs,Find Some Who... or Team Brainteasers
10am-12pm Introduce Scratch
Scratch is free software created at MIT that lets you create 2D animations, interactive art, and games. We will will use both the new Scratch 2.0 and Scratch 1.4. Go to the Scratch website and students create their own account to keep their Scratch creations in so they can access them at home as well as at camp.
Show the students the support page at and the video page at Have them view the "How to use Scratch intro" video (the one on the right). Show them how to open the Examples folder and look at the Animation folder and pick 8-DayDream and in the Music and Dance folder show them 6 BreakDance and maybe 2 ChickenNoodleSoup. Then show them how to do start a Scratch project using the green flag and how to end it with the red stop sign. Show them where to find the documentation on a Scratch project (in the File menu).
The students will see, then create the Cassie Dancing animation. to prepare for the Scratch project they make Tuesday that has their green screen photos in it. Students will have time to brainstorm for ideas for their own animation, do a simple storyboard, and think of/sketch (stick figures) poses that will fit the actions of themselves in their own animation.
12-1pm Lunch break
1-1:30 pm green screen pictures, three poses per student for use in Scratch animation
1:30-2:15pm Explain what a Remix is. Show how broadcast works. Students have 30 minutes to just open and play with Scratch projects. They pick a project to change the Stage, change the costume of a sprite, add a new sprite, add a "special effect" like color or ghost, make and add their own recording for a sound for one of the sprites. Give them time to work on their storyboard for their animation
You can also show them the Scratch cards (at and have them try out one of the ideas from a Scratch card.
2:15 to 2:45 - CS Unplugged - Binary Dots - Binary "Deciphering" Challenge
2:45pm Ask for questions from the day

9:00-9:45am Scavenger Hunt
9:45-10:45pm Show them how to create an interactive art project in Scratch. See
10:45-12:00 Show how to create a simple 2d animation in Scratch
Show them how to import their green screen photos into their Scratch project. Their photos will have green removed already, but show them how they could use the transparency and eraser tools at home to delete the green background from their green screen photos, making themselves the stars in their 2D Scratch animation.

12-12:30pm Lunch break
12:30- 1:00 CS Unplugged "Magic Card Trick" - Illustrating Parity. error detection and correction card trick (see
1:00 - 2:45 - Students create their own 2d animations, featuring themselves in the leading role, and show their creations to the group. (TAs work with two sets of two students to let them each do the card trick and be sure they can show it to others.
2:45pm Ask for questions from the day

9:15am- 11:30 pm (Using Scratch 1.4, not 2.0)Students work in pairs with the PicoBoards doing the musical pickle, reaction game, and kinetic sculpture.
Encourage them to try all the reaction game parts (use touch sensor, try with light and sound, try with resistance sensor, try with hands and feet).
Give them the Reaction Time Record sheet to record their times. Ask who had the fastest reaction time. If they finish early add another of the placement activities.
Introduce the sensor modules. Have a sprite that dances based on sound sensor input and change colors or shape based on varying light sensor input.
Make a musical pompom (pickle, grape or potato) that plays different notes depending on electrical resistance.
Take your Pong game and modify the programming to control the paddle with the picoboard slider instead of arrow keys. (The slider becomes your game controller) or create a paper puppet, connect with alligator clips to PicoBoard and have your puppet interact with Scratch characters in a story you make in Scratch. Video students with puppets, etc. interacting. Have them narrate video
Downloads for Picoboard projects on website
If you want to see the code or just a sample of one of the projects we'll do, download one of the ones below. REMEMBER!! Currently, you have to use the older Scratch (version 1.4) for these to work. It's a free download from
Download PicoBoard Reaction Time Time to using alligator clips Sound (SB)
Download PicoBoard sensor sample code program (SB)
Download PicoBoard Reaction Time to Movement (SB)
11:30-12:00 -CS Unplugged - the Oranges Game
In this game you five people are in a circle. Four of them have two unmatched objects. One person has only one object. Each object has one matching object (like two yellow tennis balls, two orange ping pong balls) You and your team have to pass the objects around so that the matching object are in the hand of the person wearing the matching color card. Oh, yes, there is a small problem. You can only pass to the person next to you and only if that person has an empty hand.
To help you get the idea, here's a Scratch game that lets you try to Win the Oranges Game.
12:00- 12:30 pm break for lunch
Swimming in the afternoon

Thursday Video the students doing activities. Have students take turns doing videoing.
9:00 am Answer questions from the previous day
9:15 – 10:30 am Exploring WeDo sensors and motors and interactivity with Scratch sprites, sounds, etc. using Frogger, Tilt pen, Crazy Helicopter with Tilt, distance, and motor, SpinArt, UpDownDuck, Catapult. (Links to all game samples and builds are at

Optional- Add a “real” LEGO from and attach to motor to have it move when you move the Sprite Frog
2:00-2:45 (student skits – video these)
Live Programming – teams of three pick one or two programming blocks (loop forever or repeat, if-then-else, if touching color, while, >, , glide x and y, and make ups a skit showing what that block does
Computer terms team Jeopardy - 4 teams of six. Two rounds for each team. Each team has a whiteboard - no talking - person writes answer, shows to team members. If another member has different answer, writes it down. They vote silently to decide which answer to show. All four teams show answer at same time. All teams with correct answers get point. top team - each team member gets 4 pieces of candy; 3 for second place, 2 for third place, 1 piece of candy per team member for fourth place.
