Science Showcase: Fair at Cal Expo Spotlights Projects from 250 Students

Richard Woonacott, a judge, looks for the W.O.W. in a science project -- something that will allow him to say "what outstanding work."

He was definitely impressed by the effort shown by students at the Sacramento Regional Science and Engineering Fair held Saturday at Cal Expo. The fair showcased projects from about 250 students from eight counties in the Sacramento Valley. It was open to students in sixth through 12th grades.

"It's nice to converse with the students and hear what they say about the project, whether they followed a scientific method," Woonacott said.

He can also tell if the project is the student's own work or if they had help.

The sixth annual event featured entries from volcanoes to more elaborate intellectual displays, such as a project on monitoring heart rates.

Prizes were awarded in 14 areas of study including chemistry, math and computer science, behavioral and social science.

Mira Loma High School swept the competition. Individual winners included Shara Cohen, a senior, and Jonathan Palley, a junior. Mira Lalchandani and Denton Sato were the best in the team category.

Cohen's project created a greater understanding of the ecosystems and feeding patterns of fish and other species inhabiting Eagle Lake by measuring their intake of zooplankton, a primary food source, said Ted Toppin, science fair director.

Palley's project is an original computer program that allows people to learn languages, math and spelling by using virtual computer flashcards.

The team project focused on cancer and genes.

All four received a trophy, a scientific calculator and an all-expenses-paid trip to compete in the International Science and Engineering Fair in Louisville, Ky., in May.

Saturday's event was sponsored by the Intel Foundation, the California Association of Professional Scientists, the Professional Engineers in California Government, Hewlett-Packard, SMUD, Agilent Technologies and Cal Expo.

"A science project is about asking a question and coming up with an answer," Toppin said.

For example, Jasmeet Bhullar, a seventh-grader at Center Junior High School, wanted to know which brand of double-A battery is most cost-effective.

He used five different brands of batteries, placing them one at a time inside a travel clock. Then he wired a light bulb to the clock to help drain the battery. He was able to determine when the battery ran out by the time on the clock.

Bhullar chose to focus on batteries because so many items in the home depend on them, and he learned that just because a battery cost more, it doesn't mean that it will last longer.

"Now, I know which batteries to buy," said Bhullar, 12.

Discovery was part of the fun for the students.

Kinnaly Bouttavong and Apryl Galanta, both juniors at Foothill High School, worked together to see if drinking sage tea, a stimulant, increased people's memory.

They had 16 people drink either sage, green tea, or a combination of both, before playing a game of memory in which participants tried to find the matches for a group of cards.

Although some people were able to find the cards faster over time, the girls were not sure whether it was because the people in the test group were getting more practice with the game or if their memory was actually increasing because of the sage tea.

"You learn from your mistakes," Galanta said.

The girls determined that they should have used a larger sampling of people, and a control group that should have been given water.

Many students tackled behavioral and social issues.

A group of students from Folsom High School focused on how surroundings affect eating disorders.

Natasha LaBeaud, a freshman, learned from her research that extreme temperatures make people stay inside more and they tend to become overweight. She also said stress affects weight.

One of her teammates, Kavita Khandekar, said she was surprised to learn that some people perceived themselves to be too thin or too fat.

Toppin said he was amazed by the hard work and creativity of the students.

"They were able to complete these projects in addition to homework, soccer practice and piano recitals," he said. "It's another way to show colleges that students are competitive."
