Acid Base Titration Lab

Posted on:

Westside students recently completed an Acid / Base Titration Lab in Chemistry. The students were using a 0.2M acid in order to determine the strength of a basic solution made from magnesium hydroxide. This is accomplished with the use of an indicator which changes color when all the base has been neutralized. Ultimately, they will use their results to determine how many moles of stomach acid can be neutralized with one dose of the medicine.

Our students look great in goggles and other assorted lab gear!

Anatomy & Physiology students were (gloved) hands on in a recent dissection lab. Students were dissecting pig hearts, and during the process, were instructed how and then proceeded to, inflate the lung.

Take a look at the short video of our school scientists below!

 

 

Battle of the Beaks

Bird beaks

Bird beaks

In a Battle of the Beaks exercise sophomore Biology students recently learned how animals better adapted to take advantage of available foods fare better than the less adapted, and thus live to pass on their genes to the next generation.

Bird beaks were represented by chopsticks, a spoon, tweezers, and a staple remover. Students needed to use their beak implement to pickup various items representing different foods. Thirty seconds were given to collect as much of one food type as possible, before repeating the activity with different types of food.

At the conclusion of the exercise, students were asked to answer what they noticed about their feeding abilities, and reflect on what would happen if a natural disaster caused a certain food type to disappear.

Atom Particle Lab

Charged particles making the tinsel move!

In Intro to Chemistry freshmen students learned that they can strip the outermost particles of an atom (electrons) from one substance (hair and a piece of fake fur) simply by friction and observe the effect of those charged particles on other items. In the images below, you can see they made the tinsel move toward the acrylic rod.

They also made a soda can follow a balloon and bits of confetti jump onto a comb!

Welcome Janell Galloway

Janell & Scott Galloway, in Paris!

Janell & Scott Galloway, in Paris!

Mrs. Galloway will be teaching Physical Science, Conceptual Physics, and Chemistry.

I’ve been married to Scott for 35 years. We have two sons, and our oldest son lives not too far away and is married with a three year-old and another on the way!  Our youngest son is in Washington and just got engaged!  Blessings poured out, pressed down and overflowing!

My husband enjoys fishing and hunting, I enjoy teaching 🙂 and we both enjoy traveling.  I have a few verses that I like to remember:

  • James 1:5 “If any of you lacks wisdom, you should ask God, who gives generously to all without finding fault, and it will be given to you.”
  • Matthew 18:20 “For where two or three gather in My name, there am I with them.”
  • 2 Corinthians 12:9 “My grace is sufficient for you, for My strength is made perfect in your weakness.”
  • Ephesians 3:20 “All glory to God who is able to do far more than all we can ask or imagine, according to His power at work within us.”

WCHS in Belize!

Kylee Wiseman, Mrs. Little, Hayley Sprague, Jack Stevens, Susannah Fischer, and Brittney Martin

Mrs. Little and five Westside students (Kylee Wiseman, Jack Stevens, Hayley Sprague, Susannah Fischer, and Brittney Martin) had the opportunity to join students from various states across the US on an 8 day nature field study trip in Belize with a program called “Save the Rainforest”.

Students went on several hikes through the rainforests (including a couple of night hikes) to learn about the diversity of the Belizean flora and fauna. They visited Mayan ruins, went tubing through mangroves, and discovered many bizarre and beautiful creatures. Students also learned about deforestation, habitat destruction, and displacement of animals in Belize. They learned about conservation efforts and sustainable logging practices that a few programs are trying to implement in Belize. Students had a first hand experience with what it means to be good stewards of nature and what results from unsustainable timber and animal trafficking activities.

New little green friends!

Physical Science Fair

Posted on:

The Science Project is a year long project in Physical Science. It begins with a Background Paper, where the students research a topic of their own choice. Students then write an Investigation Plan. The Investigation Plan is based on an experiment the students design based on their Question (or Problem) and their Hypothesis. 

Following the actual experiment, with clearly defined variables and an experimental group, students complete an Investigation Follow-up Report. In this report, they analyze their data, document trends, discuss their hypothesis, and tie what they learned back to their Background Paper. The last piece is to create a display to show off their work. This year, the senior Bible class served as judges.

AP Biology Bacteria Plates

AP Biology students successfully inserted a jellyfish gene (green fluorescent protein) into E. coli bacteria, which caused the colonies to glow in the dark. Students below gather around the dark bacteria plates glowing in the dark!
