Convection is one of the ways how heat is transferred involving liquids and gases. Movement of liquids (or gases) happens because of the temperature differences between two areas of the liquid (or gas). This video is a simple activity to demonstrate convection in liquids using common materials like glass jars, water, food coloring, and plastic basin. Teachers can make use of the questions shown in the video to form an inquiry-based activity. The teacher can either use this video or simulate one in class with the students doing the task. This is an appropriate activity as a lesson material for grade 4 students.
