During the Science Week Grade 10 made their own versions of Organic Ice Cream in line with their topic in Chemistry which is Organic Chemistry. They tried to make variety of flavors from using fruits, nuts, and green tea. They also observed the temperature required to form the ice cream texture, use of salt to lower the temperature and keep the ice from melting.They all enjoyed this fun activity.

CISM celebrates Science Week 2018. Elementary and Middle School students come to see the interactive and informative exhibits prepared by our MS/HS and IB Science classes.

Some groups presented simple science chemistry and  physics experiments and tricks to other students while the other classes exhibited their projects and inventions. Gr.9 Biology class showcased their 3D models of biomolecules while IB Biology students showed their terrestrial mesocosms.

Science rocks!

G10′s had a lot of fun learning how to test different chemical indicators and knowing how to distinguish acids from bases during our Chemistry class. They were able to learn skills such as proper handling of glasswares and using other laboratory tools such as the ph meter where the students were asked to make an interpretion on the digital readings as they test each samples. Also, they practiced laboratory safety by wearing safety gears since there is a need for them to get work with acids and other chemicals. A follow-up experiment on making their own organic indicator using flowers and red cabbage.

Grade 7 enjoyed making their soap project in Chemistry as one of their final requirement for the 3rd Quarter.
They were able to make use of their skills in proper handling of laboratory apparatus and as well as practice safety in the lab while working on their soap project. They used different prcesses in creating and improving their product such as melting, freezing, purifying as well as using methods to avoid contamination of bacteria. Using an existing organic soap base the class which was devided in 2 groups were able to make different variants . They used organic ingredients such as flowers, oats, cinamon etc.. and researched on the additional health benefits when added to their soap product. The class enjoyed working with their groups and collaborating their ideas.

Finding Evidence of Chemical Reaction

Grade 10 is learning about the evidences of chemical reaction in this experiment they will recognize that formation of precipitate is a result of chemical reaction. They used different compounds in the laboratory and experimented on the reactions of each when mixed.at the end of the the experiment as part of post-lab discussion they were able to identify mixed compounds that undergo chemical reaction.

Grade 6 JL and Gr.9 students study the cell, its structure and functions. They were also able to observe prokaryotic and eukaryotic cells under the microscope. In addition, students created their own analogy of the cell structure and functions. Some groups compared a cell and its parts with a chocolate factory. Another group compared the basic unit of life with a hospital.

Grade 10 Systems Design and Society students presented two versions of their chosen product’s Life-Cycle Assessment. The first LCA is of the traditional product that we could buy in the market today. The second LCA is of the new improved version of the product.

Students were grouped and decided to work on LCAs of eco cream eyeshadow, powdered shampoo and bio handsoap. As part of their final requirements for the course, students presented their LCAs in class and in front of Gr.9 students. They also showcased their actual final products. Gr.9 students tried the products to see its effectiveness.

Interactive System Models

Gr.10 students created interactive system models as a summative assessment for the subject Systems  Design and Societies.

One of the groups made a model for Water Cycle, the other group prepared a model for the Human Digestive System while the third group created the Urinary System model.

The fourth group created a model of the Human reproductive systems. It showcases how the sperm cells approach the mature egg cell in the fallopian tube. In this model, the students used Hot wheel toy cars and its tracks to simulate sperm movement.

Genetic Offspring Models

Problem: Based on the genotype and phenotype of the
parents, can you design a model of the offspring?

Gr.7 students chose chromosome pairs (one from each
“bug” parent) with specific genotype and phenotype.
Students created models of bug offspring using the
known traits of its parents.
