High School

You’ve likely experienced older adults with hearing aids struggling to hear what you’re saying to them. You probably feel like hearing loss might have something to do with age, right? But have you ever considered which types of sounds they find the hardest to hear? Since sounds are made of waves which vibrate at different frequencies, certain types of sounds are harder to hear! In this exploration, festival goers will participate in an experience to investigate how aging impacts hearing.

Participants will balance bricks on levers, feel the benefit of using pulleys, and see how inclined planes can decrease work.

Student pharmacists will help to educate the public with activities related to asthma, diabetes, hypertension, immunizations, medication safety, and poison prevention.

From bouncy balls to slime, participants will explore the chemical principles and properties of polymers.

Since 2009 Castle Park High students, with Dr. Pomeroy of UCSD, have learned to produce biodiesel from vegetable oil. Students use a particle counter to determine how “clean” the fuel burns and discuss how particulate impacts our global climate. Students present this field data to support the benefits of biodiesel. Our booth, as in years past, will demonstrate the step-by-step process of biodiesel synthesis, discuss the advantages of biodiesel over petroleum and outline the ease of production.

The e3 Civic High STEM booth will feature a robotics demonstration from the school's FIRST Robotics team, the Griffins. The booth will also feature an interactive gardening experience that will allow visitors to pot and take home a small plant that will inspire them to think about how they can contribute to a greener world. Whether interested in human anatomy and physiology, aviation, robotics, agriculture, or nutrition, scholars can explore their curiosity for STEM at e3 Civic High.

Come and participate in an interactive experiment and learn all about the fun science programs we offer to the community!

Guests will understand the principles of buoyancy by experimenting with their own diver. Participants will be able to- ● Define and understand the concept of buoyancy ● Explain how a fish moves up and down in the water column ● Engage in the scientific process by conducting a water experiment using a diver and playing with the concept of buoyancy.

We will have multiple interactive stations including: 1) Comparative Brain Anatomy- play a guessing game to see which brains belongs to which animal species. 2) Sheep Brain- hold preserved sheep brain and learn about parts of the mammalian brain. 3) Spiker Box- make a cockroach leg dance and learn about how your brain communicates with your muscles to guide your everyday movements. 4) EMG Module- learn how we can use electrical activity from your muscles to control a mechanical claw.

We will be explaining the chemistry (acid/bases) behind invisible inks. Kids will write messages to their friends or family, and we'll show them how to reveal the invisible messages. The invisible ink will be dilute laundry detergent, milk, or soapy water. They'll write the messages using a paintbrush or cotton bud, and optionally add a "cover up" message using regular pen. Then we'll show reveal the invisible message by shining ultraviolet light on the paper, or by spraying a basic solution.
