Learning About Earth Science

The 6th graders are continuing their exploration in the field of earth science. They are learning about minerals and the rock cycle. During this unit they will define, describe and identify how a mineral is made and where it forms. They will be able to identify and describe the characteristics of igneous, sedimentary and metamorphic rocks as well as their formation. By the end of the unit they will be able to describe and discuss the rock cycle. During their first lab of the unit, Identifying Minerals, the 6th graders tested the streak and hardness of some minerals samples and based on their observations they were able to identify each mineral as either hematite, calcite, talc, lodestone or quartz. Rock on 6th graders!

Learning about Science in 5th Grade

Fifth grade science students have been busy investigating and learning about how plants, animals, and fungi form a system and how they are dependent on one another.  Students modeled the flow of energy in food webs and observed worms to discover how they release nutrients and help plants grow. Then they designed their own experiments to examine earthworm behavior.

Elementary Science Olympiad Team

The students who participated in this years’ team ranged form 3rd to 5th grade. Students competed in events such as Junk Cars, Backyard Biologist, Building Catapults, Wild Weather and other events. LaSalle II placed in 8 out of the 12 events!

8th Grade Science Olympics

The 8th grade class began their science explorations with STEM challenges of Olympic proportions! The students were given 5 different challenges, Regatta, Dominoes, Aerodynamics, Cartesian Divers, and Slow Roller. After a brief introduction to each challenge the students, working in groups, chose three of the five challenges in which to compete.

The students then researched concepts associated with their challenge, discussed and formulated a plan of action and tested their hypothesis. On the day of their challenge the students had 15 minutes in which to create their final hypothesis based on their observations and results from the practices.

Regatta: Students researched buoyancy and created a boat from wax paper, aluminum foil, or copier paper. Once the students had their construction floating they would had gram cubes until the boat began to take on water. The winning boat held 1305 grams!

Dominoes: Students researcher force and inertia. They then designed how they would set up 100 dominoes to knock down with a single push. Each branch added an additional 10 pts. Each 110 degree curve added another 10 pts and any dominoes that fell up or down an incline would gain a two pt. bonus. Highest competitor was 295 dominoes!

Aerodynamics: Students researched Bernoulli’s principle in terms of flight and the force of air. Students designed a paper airplane that would fly as far as it could while remaining in a 90cm width. The longest flight went over 10 meters!

Cartesian Divers: Students researched Pascal’s principle. Placing three divers into a 2 liter plastic bottle filled with water. Students had to manipulate the density and buoyancy of the divers to make them descend on a specific order and rate. Very challenging but all teams were successful!

Slow Roller: Students researched force, inertia and friction. Using a variety of objects, such as, rulers, wooden dowels, and yarn, students designed a course that with a single push keep a marble rolling as long as possible without going off a large piece of construction paper. First and second were divided by a mere .01 second!

Each team earned 5pts for a first place finish, 3pts for a second place finish and 2pts for a third place finish. After all of the challenges were completed the totals were tabulated and the overall Science Olympic Winners for the 2018-2019 school year are:

First Place:

Trevel A.; Alexis G.; Brooke A.; and Karrion W.

Second Place:

Fidel R.; Jalen D.; Chloe N.; and Brenden D.

Third Place:

Maeve Mc.; Eric R.; Felix Z.; and Jalen J.

You Be the Chemist

The You Be the Chemist team competed last weekend at North Park University. Nora L. took 5th place out of 52 students and will be moving on to the State competition. The Demonstration team, composed of Alex V., Grant L., Kania W., and Robert Z., took second place out of 26 teams on their understanding of chemistry knowledge and demonstration.

Congratulations Christopher P.!

Christopher P., an 8th grader, was featured on the Tonight Show with Jimmy Fallon with the GE Fallonventions. He was selected to present his invention from the Invention Convention that he created last school. He also competed at the National Competition in Washington D.C. with his invention last Spring. You can view the segment by clicking the link below. We are so proud of you!

Invention Convention

The seventh grade representatives of LaSalle II competed in the CSIC (Chicago Student Invention Convention) at Clemente High School on Saturday. There were about 300 presenters. In the Junior High division, of 34 students, Kira S. and Jadah C. took fourth place. Grace P. took third place and Christopher P. took First. Christopher has also been invited to participate in the National Invention Convention in Washington D.C.. Also, participating were Andrew W, Willem P, Amelia L, Lesly G, and Luke M.

8th Grade Science Fair

Emma Z. and Tiffany L. recently participated in the regional Science Fair and have qualified for the city wide competition.
