Southbridge International School Cambodia has shared a look inside its Year 5 science lessons, where students explored materials, measured solutions and recorded physical changes through hands-on experiments. The school described an active laboratory session in which pupils worked together, tested hypotheses and documented observations. Photographs show small groups using containers and other classroom science equipment while a teacher supports their activities.

In its Facebook announcement, Southbridge International School Cambodia described the Year 5 students as “scientists at work.” The post highlights three main elements of the session: investigating materials, measuring solutions and recording changes observed during practical tasks.

The photographs show students in blue school uniforms working at tables with clear cups, small containers and measuring equipment. One image shows an adult assisting a group. The post does not identify the substances used, the precise experiments conducted or the scientific conclusions reached by students.

The activity illustrates how a laboratory setting can give primary school pupils opportunities to investigate questions directly. Instead of relying solely on descriptions in textbooks, students can observe what happens when they carry out a procedure.

Why hands-on experiments support science learning

Practical investigations can help children connect scientific vocabulary with things they can see and measure. When pupils handle materials, compare results and record changes, abstract ideas become linked to observable evidence.

A useful investigation begins with a question that can be explored safely. Students may predict an outcome, follow a procedure and compare their observations with the original prediction. The aim is to develop reasoning, even when results differ from expectations.

Teachers can strengthen this process by asking pupils to explain what they noticed and how they know. Recording measurements and observations also provides material for later discussion, helping students distinguish evidence from guesses.

Testing hypotheses and recording observations

Southbridge reports that students used laboratory equipment to test hypotheses and document real-time observations. A hypothesis is a proposed explanation or prediction that can be examined through evidence.

At primary level, students can practise identifying what they will change, what they will measure and which conditions should remain consistent. These habits introduce the idea of a fair test, although the level of detail should suit the learners’ age and experience.

Written notes, tables and simple diagrams can help pupils organise findings. Teachers may encourage them to describe changes accurately rather than rushing to conclusions. Comparing observations within a group can also reveal differences that need further investigation.

Collaboration in the primary science classroom

The school’s announcement emphasises teamwork during the science session. Collaborative experiments can give children opportunities to share tasks, discuss predictions and check one another’s measurements.

Group work is most effective when responsibilities are clear. One student might measure materials while another records observations, with roles rotating so everyone can participate. Teachers can guide students to listen to different ideas and explain disagreements using evidence.

Laboratory safety remains important. Pupils need appropriate supervision, clear instructions and equipment suitable for their age. Families should not attempt to reproduce unfamiliar experiments at home without knowing the materials and safety requirements.

Encouraging curiosity beyond the laboratory

Parents can extend science discussions by asking children what they investigated, what surprised them and whether their predictions matched the results. Such questions invite students to explain their thinking without requiring adults to know every scientific detail.

Everyday observations, including changes in temperature or the behaviour of familiar materials, can provide starting points for age-appropriate questions. Teachers can then connect these experiences to classroom topics and structured investigations.

The Southbridge International School Year 5 science activities demonstrate students engaging with practical investigation, measurement and collaborative observation. The school’s photographs and account document a classroom experience focused on testing ideas and developing scientific understanding.
