Musicology – Friday
Today, students put final touches on their hand-pipe machines, creating a mechanism similar to a music box, and continued their experiments on digital vs. analog transmissions. They then learned how musical reeds work and even created their own reed-like instrument using straws. Finally, students put all their knowledge of music together by defining what made music “good” to them. They used this knowledge to categorize and rate music that their peers might like as well.
Ask your students:
How does a reed work? (it vibrates when you blow into in, thus creating a sound)
What does binary mean? (Something composed of 2 parts; a digital signal is composed of 1’s and 0’s)
Book Recommendation: A Crooked Kind of Perfect By Linda Urban
This young adult novel is recommended for 5th-7th grade students.
From Amazon: “Ten-year-old Zoe Elias has perfect piano dreams. She can practically feel the keys under her flying fingers; she can hear the audience’s applause. All she needs is a baby grand so she can start her lessons, and then she’ll be well on her way to Carnegie Hall.
But when Dad ventures to the music store and ends up with a wheezy organ instead of a piano, Zoe’s dreams hit a sour note. Learning the organ versions of old TV theme songs just isn’t the same as mastering Beethoven on the piano. And the organ isn’t the only part of Zoe’s life that’s off-kilter, what with Mom constantly at work, Dad afraid to leave the house, and that odd boy, Wheeler Diggs, following her home from school every day.
Yet when Zoe enters the annual Perform-O-Rama organ competition, she finds that life is full of surprises–and that perfection may be even better when it’s just a little off center”
Micro STEM @ Aurora – Thursday: Magnifying Investigations
Today, the investigation of different kinds of magnifying devices continued. Students got the chance to go outside and collect various samples of their choice. After collection, the samples were brought inside to be analyzed with a compound light microscope. Students also reviewed the various parts of a compound microscope, and the importance of each part in the function of the microscope as a whole.
Ask your student:
What similarities and differences did you notice when you were using the different tools for magnification (MicroPhone lens, hand lens, compound light microscope, and stereoscope)?
Musicology – Thursday
As our camp comes to a close, students worked to solve unanswered questions and finish up engineering projects. In the morning, students queried “what is music?” and worked on breaking down/ creating harmony and dissonance using electronic keyboards. Students also dissected harmonicas to discover how they and other reed instruments function. In the afternoon, students worked to automate their hand-pipe machines using a wheel-and-axel and conducted an experiment to demonstrate the effectiveness of digital vs. analog signal transmission.
Ask you students:
What did the observations from the videos add to your understanding of how a harmonica works? (Answers will vary)
What was the content of the first recording ever made? (Thomas Edison reenacting Mary Had a Little Lamb)
Book Recommendation: Echo By Pam Munoz Ryan
From Amazon: “Lost and alone in a forbidden forest, Otto meets three mysterious sisters and suddenly finds himself entwined in a puzzling quest involving a prophecy, a promise, and a harmonica.
Decades later, Friedrich in Germany, Mike in Pennsylvania, and Ivy in California each, in turn, become interwoven when the very same harmonica lands in their lives. All the children face daunting challenges: rescuing a father, protecting a brother, holding a family together. And ultimately, pulled by the invisible thread of destiny, their suspenseful solo stories converge in an orchestral crescendo.”
Musicology – Wednesday
Today, the students put their knowledge of sound waves and their frequencies to practical application to discover octave equivalency; they found patterns in notes and chords by playing their own virtual pianos. Additionally, students worked more on improving their hand-pipes and electronic instruments by creating drumming levelers and reverse engineering a speaker, respectively. Finally, students related language to music and discovered new ways of music representation and possibly teaching!
Ask your students:
What patterns did you see in frequencies of notes that sound well together? (They were equal factions apart)
What were the basic parts of your speaker? (Wire coil, cup, and magnets)
Book Recommendation: Hiding Out at the Pancake Place By Nan Marino
From Amazon: “Eleven-year-old musical prodigy, Elvis Ruby, was supposed to win the most coveted reality show on television, Tween Star. None of the other contestants even came close to his talents. But in the middle of the biggest night, with millions of people watching, Elvis panicked. He forgot the words to the song. He forgot the tune. He forgot how to play every single instrument he’d ever known and froze on national TV. So Elvis must run from the paparazzi camped outside his door and spend the summer working with his aunt and cousin at Piney Pete’s Pancake Palace in the remote wilds of New Jersey. It’s the perfect place to be anonymous, that is until Elvis meets Cecilia, a girl who can’t seem to help blurting out whatever’s on her mind.”
Micro STEM @ Aurora – Wednesday: Ionic Compounds
Today, in Micro STEM, the students built upon their knowledge of atoms and ions as they used their own bodies to represent atoms and ions that bond to form ionic compounds. The students played a game where they were challenged to find a partner “match” to create an ionic compound with a net charge of zero. Also, today in Micro STEM, the students built simple ionic compounds and then created crystalline structures with the whole class.
Ask your student:
To create a neutral ionic compound with a Sodium ion (+1 charge), what charge would the other ion have to be? (-1 charge)
Musicology @ Aurora – Tuesday
Today, the students put on their creative thinking caps when they were tasked to create their own harmonica songs! Ask your child to play their creation (or their mastered Mary had a Little Lamb) for you as they will be bringing their instrument home tonight. These creative juiced kept flowing as the students finished building their electronic instruments and were encouraged to perform a song of their choice for their peers. Additionally, the students put their hands to work by building their own hand-pipe instrument which they will be expanding upon later in the week. To tie this cacophony of sound all together, the students explored an online PHET simulation where they could explore sound wave and their properties further.
Ask your students:
If you increase the amplitude of a sound what happens? (The sound becomes louder)
What were the 4 components of your electronic instrument? (Battery, Vibration circuit, speaker, keyboard circuit)
Book Recommendation: The Way to Stay in Destiny By Augusta Scattergood
This young adult novel is recommended for 4th-7th grade students.

Micro STEM @ Aurora – Tuesday: Applied Circuitry
Today, the campers continued working on their hand fans! Now that their main design had been sketched and the handle and main body was build, the budding electrical engineers could start with the circuitry and wiring. Using a small motor, a battery pack, and lots of wires, the campers finally got the head of the fan to move! We can’t wait to see their final projects tomorrow once they add lights and complete the design.
Chemapalooza @ Aurora – Friday: So Sublime
Today students observed first-hand how regular ice and dry ice differ in their behaviors. Students studied both types of ice in one scenario, and used their observations to predict what would happen in a different scenario! Finally, collected evidence to make claims about the strange phase-changing properties of dry ice, created models, and presented them to the group.
Ask your student: What is it called when a substance goes from a solid straight to a gas? (Sublimation) Ask your student to tell you some of the differences they observed between dry and regular ice.
CSImsa @ Aurora & Belleville – Friday: Drops to DNA Part 2
The case has been cracked! Our junior forensic scientists worked in the lab today in order to extract DNA from the pieces of a broken vase that were found at the crime scene. After analyzing the evidence and comparing it to the DNA samples from several key suspects, the CSI team has identified the culprit!
Students concluded the week with a successfully cracked case, and experience with real CSI science!
Ask your student:
Were your suspicions from earlier in the week correct? If not, what evidence changed them?
Micro STEM @ Aurora – Monday: Bacteria Among Us
Students began a two day project today, investigating bacteria that surrounds us. Each student will test their own fingers, and each group of 4 students could pick up to 8 different surfaces to see what kinds of bacteria live there. Alternatively, the students could choose to see what happened to the bacteria from the same surface with some sort of treatment (applying hand sanitizer, soap, etc.). Students were given the chance to make a hypothesis about what they expect to see on their plates. Later on this week, the students will use a microscope to look at the results of their samples, and test their hypotheses.
Ask your student:
If bacteria surrounds us, why don’t we get sick more often? (Not all bacteria are pathogenic (disease causing))
What are some examples of places where good bacteria are found? (Almost anywhere has some amount of good bacteria, some examples would be in our intestines and mouth)
