Students will receive their workshop schedule at conference check-in.  Workshops are assigned considering the preference indicated during registration and workshop size limitations.  We cannot guarantee the same workshops, but we can attempt to coordinate your daughter's schedule for the day so that she has the same lunch and special activity session as her friends or sister.

The EYH conference is designed so as to expand your daughter's horizons and for her to learn new things! Please have her keep an open mind and try something new. Workshops will be assigned according to the payment time stamp, so register early and preferably online. Workshop limits are set so that each girl gets personal attention and hands-on experience. We try to give each student at least one of their top five preferences.

Typical workshops offered for the Tri-Valley EYH Conference are:


A Warming Planet

Climate change is a very hot topic right now. In this workshop you'll build your very own terrarium to understand the greenhouse effect and the water cycle. Then we'll make clouds in a bottle and experiment with an infrared radiation camera to understand the roles of clouds and radiation on climate change. Finally we'll play games to explore the effects of people on climate change.

Amazing Every-Day Chemistry

We are surrounded by chemistry every moment of the day. We will discuss some of the amazing chemistry associated with common household stuff using interactive demonstrations and experiments. You will then explore the chemistry behind disposable diapers and use your science and math skills to compete in a “Diaper War” experiment to determine, based on experimental results, how much water a disposable diaper can hold and the effectiveness of the polysno vs cotton. Are you up to the challenge?

DIY Projector

You will build your own shoe box projector that can be used with cell phones/ipods. You will learn about various types of Engineers that are involved in product development, products currently in development that involves a camera and the basic theory of optics, focal length etc.

Engineering Bridges with Pasta

Have you ever thought about becoming an architect or a structural engineer? Come and enjoy a workshop where we will be building bridges using one of the most common ingredients in our diet: pasta! You will work with a variety of pasta shapes, glue and basic tools to develop and test a small scale bridge while learning about basic principles of structural engineering, architecture and design.

Experiments in Space – where no one can hear you scream

See ice, water & steam at one time. Coat a penny with gold. Figure out what happens to water, light, and sound when there is no air. Watch a marshmallow Peep blow up. These hands on experiments promise noise and fun.

Fun With Science

Experience an exciting fast paced collection of experiments demonstrated by hands-on volunteers. You will enjoy exploring light, states of matter, air pressure, electricity, chemistry & more - all

Get to Know Your Brain!

Participants will dissect a sheep brain and compare the neuroanatomy with a human brain.  We will also discuss brain function as we are dissecting certain brain areas.

Green Power!

Green Power! is a fun, hands-on, interactive workshop where girls learn the science behind wind energy, and test out their blade designs on model wind turbines. The girls can use the turbines to generate electricity, pump water, or lift weights to see the principles of mechanical work and electricity in action.

Greenhouse Gases: From Tailpipe to the Ocean

Learn more about greenhouse gases in the atmosphere, and how they affect life in our oceans, through a hands-on experiment showing the effect of rising carbon dioxide levels in seawater.

Help Solve a Cyber Crime

A serious crime was committed at a high school involving computers.  Your assistance is needed in investing the crime and to see if you can figure out who committed the crime.  See if you can solve this actual crime.

Inside Computer Technology

Have you ever wondered what is inside a computer and how it works? At this hands-on workshop you will take apart a computer, learn what each critical component does, put the computer back together again, and see if the computer will restart.  You will also use the command line interface to issue commands to complete some tasks.

Look Out! We're Surrounded by LEGO™ Robotics

Join us in discovering the many robots that we use every day, and some we do not! Build, program, and run a real LEGO™ robot. Cheer your team's robot on in a demonstration!

Mock Negotiations

How to ask for what you want and actually get it!  Learn about basic negotiation skills and how to apply to real life situations.  During the workshop you will learn tips on how to achieve a win/win agreement.

Reverse Your Tastebuds

How can we taste so many different things? How does our tongue work to allow us to taste sweet, salty, and sour foods? Why can’t every food taste sweet like sugar? Well, maybe they all can! With this miraculous natural fruit, it will turn your taste buds upside down. Discover the science behind taste and the biochemical signaling events that make it all possible.

Soft Circuits: Electronic Bling is the Thing!

Soft circuits, also known as electronic textiles (e-textiles), are electrical circuits created using flexible conductive materials (such as conductive threads and fabrics) in conjunction with electronics components (such as LEDs, batteries, switches, and sensors). You will learn the basics of sewable circuits and apply that knowledge to a craft project: a tiny stuffed monster with light-up eyes!  Knowing how to sew is helpful, but not required. 

The Physics of Phase Changes

Learn how physics can help you understand simple and surprising everyday phenomena through hands on experiments and discover the surprising properties of water and ice. Meet with experimental physicists and become one for a day!

Think, Chew, Groove!

Explore some of the fascinating organs in the human body, and learn how they function through interactive and fun group activities! Challenge your senses, build your own digestive system and run around a little to understand how the heart supports your different every day activities.

Veterinary Investigations

Learn how to become a veterinarian with Dr. Moore from the Livermore Veterinary Hospital. In this workshop you will diagnose animal patients based on symptoms you detect. You’ll use real tools and methods that veterinarians use every day, including urine and x-ray analyses. You’ll also learn what you should focus on in school if you want to become a veterinarian.
