Building Cardboard Chairs

GATE students in Mrs. Stricklin's Exploring Art class created cardboard chairs and benches that could hold 150-200 pounds.  A contest was held at lunch time to determine the winner.  The judging criteria was visual appeal and overall strength.  Chair #3, with the word "bench" on it, was the winner.  The designers and creators won an In-n-Out lunch as a reward.

Rotary Speech Contest

Congratulations to Sierra High School's Violet Vargas for her Third Place Finish in The Rotary Club's speech contest.  Contestants gave a 6 to 8 minute speech that connected the Rotary's Four Way Test to a personal experience.  The Four Way Test: Is it the Truth,  Is it fair to all concerned,  Will it build good will and better friendships, and  Will it be beneficial to all concerned, is part of the ethical guide used by Rotarians. Congratulations again to Violet Vargas and all of the other AUSD students that participated in the contest 

Installation Art at the Grocery Store

Sierra High School artists visited Albertson's Market in Glendora.  The students created two Installation Art pieces using what they've learned in class to beautify the community!  Students transformed an 8' diameter circular table into a vibrant color wheel  using vegetables from the produce section.  Another group of students created a Monet study of his wife, "Study of Woman with Parasol", using cereal, rice and chips to replicate the beautiful Impressionist painting. Friends and community members stopped by to watch students work, and it was fun for everyone involved.
