The video shows a blackboard with the words "Body Mass Index (BMI)" written at the top. Below that, there is a formula that reads "BMI = weight (kg) / height^2 (m^2)". The blackboard also lists the normal BMI range as 18.5 - 24.9 for underweight, 25 - 29.9 for overweight, and 30 for obesity. The blackboard is surrounded by various objects, including a red stethoscope and a red apple. The video is shot from a top-down perspective, and the camera slowly pans over the blackboard, allowing viewers to read the information.
