Science Fair 2014

After long days, weeks and even months of hard work, it was time for the Utah School for the Deaf’s (USDB) students to compete in the annual Salt Lake Valley Science and Engineering Fair (SLVSEF)! On March 19th, four brilliant 5th and 6th grade Deaf students competed in 4 different categories (biology, biochemistry, physics and human behavior). Each student described their project to at least 4 judges and everyone learned a lot! This was the first year for USDB to be in the regional science fair, so it was an exciting day!20140427-155034.jpg

On March 20th, 15 7th-12th grade students competed in SLVSEF and also did a wonderful job. They presented their projects to at least 5 judges each and experienced the University of Utah campus. The USDB students’ projects ranged from rockets to DNA extraction, animal bio-magnetism to cold tolerance in mammals.20140427-155109.jpg20140427-155132.jpg

 

 

 

To round out the week, on Friday, March 21st, USDB had the honor of attending its first SLVSEF awards ceremony! In addition to hair-raising electromagnetic and static electricity experiments, hundreds of students, ranging from 5th-12th grade, poured into Taylorsville High School’s auditorium to share their passion of science with one another and to continue to improve their work!

USDB had a great first year! Four students received a personal invitation to a Science Summer camp, due to their excellence in their competition category. Senait won a prestigious award from the local 4H chapter for her outstanding work with her culinary arts project. Similarly, Rhett and Meseret won a Technology and Application award from 4H for their work with biomagnetism in grazing cattle. Alexah, who worked with DNA extraction and procurement procedures, won third in the molecular biology category!

Finally, USDB was recognized as “an overly enthusiastic group of kids who seem curious and excited to learn” by the University of Utah’s Outreach program and we will begin a partnership program with them in the Fall of 2014!

Adventures in Speed calculations!

In the science of motion (kinematics) speed is defined as the rate of velocity in which an object changes it’s position. To calculate average speed, we use the simple equation:

Speed= distance / time

Speed is frequently measured in meters per second in science, but various countries which are finely attuned to their automobiles and have an affinity for speed often use miles or kilometers per hour.

In those pictures, our 110cm long school tables provided a perfect pitch for various school items and materials from the science lab to roll down.

Using handheld stopwatches, we timed how long the items took to roll/slide down the table.

i.e. Alexis slid a pen down the 110cm table and it reached the end at an average time of 2.38 secs after 15 trials. Alexis then had the proper components to calculate the pen’s speed. He first converted 110cm to 1.1 meters, then divided it by the average time (2.38 secs).

1.1 m / 2.38 sec = .46 m/s

Practice:
What is the speed of Tim’s ball rolling down a 140 cm table with an average time of 3.12 secs?

Greyhound dogs can run 291.6 meters in 15 secs. What is their speed in meters per second?

*Husain Bolt, the fastest man on the planet, can run 1490.4 meters in 2 minutes, what is his speed? (Remember, it needs to be in m/s)
