Formative Assessment for Buoyancy:

1. Multiple Choice Questions: a) Which of the following statements is true about buoyancy?
2. Buoyancy is the upward force exerted on an object submerged in a fluid.
3. Buoyancy is the downward force exerted on an object submerged in a fluid.
4. Buoyancy is the force exerted by an object on a fluid.
5. Buoyancy is the force exerted by a fluid on an object.

b) Which of the following factors affect the buoyant force acting on an object submerged in a fluid? 1. Volume of the object. 2. Density of the fluid. 3. Density of the object. 4. All of the above.

1. Short Answer Questions: a) Explain the concept of buoyancy and how it relates to the weight of an object submerged in a fluid.

b) A wooden block and an iron block of the same volume are submerged in water. Which block will experience a greater buoyant force? Explain your answer.

1. Practical Application: Design an experiment to investigate the factors that affect the buoyant force acting on an object submerged in a fluid. Include a hypothesis, materials needed, and step-by-step procedure.

2. Problem-Solving: A metal ball with a density of 8 g/cm³ is placed in a container filled with water. The volume of the ball is 100 cm³. Calculate the buoyant force acting on the ball.

3. Drawing and Labeling: Draw a diagram illustrating the concept of buoyancy. Label the forces involved and provide a brief explanation of each force.

Note: The above formative assessment can be modified or expanded based on the grade level and learning objectives of the students.
