UOI 2 Campaign Preparation - Hajun 4A

During the last weeks of UOI 2, the Year 4 students worked on a culmination project. We will share our learning and demonstrate voice, choice, and ownership by making an awareness campaign. We chose an issue related to renewable and non-renewable resources and found the effect of human use of resources on the natural environment. We communicated and discussed with partners (some of us worked individually) to make the awareness campaign using any format we like, such as Websites, Slides, Canva, Movie, Video, or others. In the campaign, we will share about the issue and how we can find solutions or strategies to balance the needs and availability of our chosen limited resources.

We will share our findings with other school community members through a mini expo. The Year 4 Awareness Campaign mini expo will be on Friday, November 4, 2022. During the process, we were thinkers, risk-takers, and communicators. We discussed with our partners and took risks to try something new to explain and clarify the issue and how to take action related to the issue.

Hands Hygiene Experiment - Maria 4A

For the science lesson in UOI 2, the Year 4 students are currently doing a hand hygiene experiment with bread. In this experiment, we aim to see why washing our hands is important because some people or students don't wash their hands properly. We are also aiming to see what happens when we don't wash our hands so our class can understand clearly what happens if we don't wash our hands properly. This is currently week 2 of our science hygiene experiment. Our class's hypothesis shows that the bread slices that were cleanly placed into the zip-lock bag won't grow mould because there will be no germs on the bread, which makes it clean. Still, the ones placed very uncleanly into the bag will have a higher chance of growing mould because the dirty bacteria and germs can get on the bread and cause the mould to grow.

Each group placed every five slices of bread into their group's separate zip-locked bags to start the experiment; the first one was inserted fresh and untouched by one of the group members in each group with gloves, the second one was touched with a dirty hand by one of the group members with dirty hands, the third one was rubbed on a device like a laptop, phone, iPad, etc. One group member touched the fourth one with hand sanitizer on their hands, and the fifth one was touched by one of the group members who washed their hands properly with soap and water.

We report our observations every 3-4 days on how the bread has changed over time, and we make sure to describe how the bread has changed in our report. We do this to track what the bread looks like and its changes. This science experiment is very useful and important because washing hands is important, especially when there are a lot of viruses and bacteria around us. Washing hands is the easiest way to prevent ourselves from getting sick.
