7th Grade Science- Astronomy

The 7th grade has begun its virtual studies with an unit on Astronomy. The 7th grade students explored the relationship between the Sun, Earth and Moon and the specific topics of constellations, reasons for seasons, moon phases,eclipses, and tides. For their explorations students built models of the sun, earth and moon. These models allowed the students to explore the dynamics of interactions between the three solar system objects.  The students also built Starfinders that they could use to locate constellations. In their studies students discovered the shape and positions of the  earth has a large impact upon the seasons we experience in the hemispheres. Students further discovered why the Dark Side of the moon is never seen from earth and why we have moon phases. All due to the rotation and revolution of the moon around the earth. 

Each student, as part of their assessments, created a google slide presentation on their research of the moon. The slide presentations clearly showed  great effort and creativity in picture selection and information gathered. Below is a star finder you would like to create one too!

6th Grade Science’s Journey to the Center of the Earth!


The 6th grade science students are finishing up their introduction into Earth Science this week after studying the spheres of the earth and the layers of the earth over the past couple weeks. Students participated in many critical thinking concepts, focusing on the two questions: “What is inside our earth/Could we dig to the center of the earth?” and “What are the layers that make up our earth?”. During this time, we created a model of the earth on a small sphere. The students had to incorporate math to figure out the scale of the earth and the layers to the sphere they were given. The models turned out great! Students also spent a day using their creative side making a ‘graffiti wall’ where they expressed why it is important to know the layers of the earth. The 6th grade is looking forward to getting out of this world and leaping into the atmosphere next! 

Elementary Science Olympiad

The Elementary Science Olympiad Teams have completed another successful year. The 34 student scientists from grades 3 through 5 competed against other schools from around the state on Saturday, 2/10. Competitions ranged from such topics as Anatomy, Crimebusters, Circuit Wizardry and many more. LaSalle II teams met on a regular basis after school to prepare for the 12 different events.


At the competition, LaSalle II students really stepped up and showed the true spirit of LaSalle II, both in knowledge and sportsmanship. Our scientists were medal earners in 5 of the 12 events.

Science Experiments in 5th Grade

Fifth grade science students are learning about chemical reactions and properties of matter. In this lab, students investigated and modeled how gases cause explosions. In the activity, Bag of Bubbles, students experimented by combining baking soda and vinegar inside a sealed bag and observed how the gas bubbles produced caused the bag to inflate–and sometimes pop!

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 1086 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 290 dominoes!

Aerodynamics:  Students researched Bernoulli’s principle in terms of flight and the force of air.  Students designed an air propulsion rocket, that had a mass of 2-4 grams, that would hit a target bullseye 3.5 meters from launch site. 

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 in 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 would keep a marble rolling as long as possible without going off a large piece of construction paper.  The longest time was 17.42 sec!

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 Champions for the 2019-2020 school year are:

  • Room 212:  Jorge G.; Naija S.; Alexis R.; Dallas B.
  • Room 214:  Kaillen V.; Brooklyn F.; Sabina O.; Alex G.

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!

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:
