ESS Experiment on Soil

As the new term begins, so does a new experiment for ESS. These experiments are really fun for students as they can gain lab work experience and are beneficial because of the lab report that has to be done following it. For DP1, we are starting the chapter of Soil Systems and Society. Soil is a necessity on Earth and one of the roles is that it helps to grow plants. Our experiment was to analyze two samples of soils, garden soil and roadside soil. With these two samples we found its pH, moisture, water capacity and texture. It is important to understand these qualities in soil because when they are in a certain condition, it is the best for growing plants.

This experiment was very messy, but it was enjoyable. The students were divided into three groups and it was a new experience for everyone. Although we have done experiments before, we did not use some of the apparatus used in this experiment, so it was a new challenge for us. Equipment such as the dropper, glass rods and the universal pH indicator was never used in previous experiments so it was difficult. What made it challenging was that we did 4 different experiments on a sample and we had to do it in under an hour and a half. This demanded efficiency from us and a lot of teamwork. Fortunately, all groups were able to collect the results they needed.

Although these experiments and the lab report after are difficult and tiring for students, it is very helpful for us as it improves our lab skills, gives us experience in practical work and is great practice for the upcoming IAs.

Inspiring Minds: A Journey of Education, Life, and Gratitude

Education is not only restricted to textbooks and classrooms; it covers a larger knowledge of life, purpose, and the pursuit of achievement. Australian International School Dhaka, promotes complete growth while inspiring pupils to attain their best potential is of highest significance. In a recent engagement project, the school invited Dr. Shahpar Nahrir, a parent of IBDP 1 students Maryam and Amina Bushra, who discussed her life experiences, opinions on education, and important life advice. Dr. Nahrir, having a background in neurological surgery at Evercare Hospital, wants to teach students the significance of hard effort, persistence, and thankfulness in their path towards making a significant effect on society. The Australian International School's dedication to offering a well-rounded education goes beyond academic differences. Recognizing the relevance of real-life experiences and ideas, the school regularly invites guest speakers to share their tales and viewpoints. Dr...

TOK Presentation

On 16th and 17th our TOK Facilitator, Mr. Sajid conducted a practice session for the upcoming TOK Exhibition in May. The TOK Exhibition is crucial in DP, especially in the first year. It contains one third of the overall TOK grade and TOK is a core component in IB. It is essential that students are well prepared for the exhibition. For the practice session, we did not do the full run through of the exhibition. For this practice session we only had to pick one object for the prompt and theme, instead of three in the actual exhibition. We had to create a display for that one object and present it to the class and our DP Coordinator. This has been incredibly helpful for the students, because it gives us an idea of what prompt and theme we will choose. We can see if we are comfortable with the object and are good at explaining the prompt or theme. The presentation also gave us a gist of how it will be like when we present our objects in front of a huge audie...

Exploring Biodiversity: IB DP Year 2 Biology Students Conduct Line Transect Activity

Recently, IB DP Year 2 biology students embarked on an exciting line transect activity on the new school field to study plant species and soil properties. This innovative method of identifying organisms within an ecosystem involves systematic sampling at regular intervals to observe and record biodiversity along a line. Using a 10-meter rope, students examined organisms every 2 meters along the transect, identifying two plant species: Cornus serica L. and Cenchrus echinatus L. . Despite aiming to collect five soil samples for testing pH, salinity, and total dissolved solids (TDS), the experiment was interrupted by rain, limiting the collection to three samples. Another challenge was the presence of bricks in the soil, which prevented digging at one of the sites. In the lab, students measured TDS levels ranging from 18.2 to 22 ppm, salinity from 17 to 18, and pH between 7.63 and 7.68. This hands-on activity provided valuable insights into the local ecosystem within the...
