متى تطفو الأجسام ومتى تغطس؟ تعلم كيف يعمل الطفو مع الكتل. تظهر السهام القوى المطبقة، ويمكنك تعديل خصائص الكتل والسوائل.
Why do objects like wood float in water? Does it depend on size? Create a custom object to explore the effects of mass and volume on density. Can you discover the relationship? Use the scale to measure the mass of an object, then hold the object under water to measure its volume. Can you identify all the mystery objects?
The purpose of this task is for students to apply the concepts of mass, volume, and density in a real-world context. There are several ways one might approach the problem, e.g., by estimating the volume of a person and dividing by the volume of a cell.
