Mini Challenge

Constructing a Water Tank

Students will work in groups to create a model of a water tank using recyclable materials. They will need to calculate the volume of their tank to ensure it fulfills a specified water storage requirement.

1. Divide students into groups of 4-5 members.

2. Provide recyclable materials such as cardboard boxes, PET bottles, scissors, glue, rulers, and tape.

3. Each group must design and build a model water tank that can hold at least 2 liters of water.

4. Students should calculate the volume of the constructed water tank using the formulas they have learned.

5. Each group will present their model to the class, explaining the building process and their volume calculations.

Utilize knowledge of volume to create a tangible object, fostering teamwork and a practical grasp of the concept.

**Duration: 40 - 45 minutes

Evaluation Exercises

1. Calculate the volume of a right prism with a triangular base with the following dimensions: base = 4 cm, height of the base = 3 cm, height of the prism = 10 cm.

2. A rectangular prism has the dimensions: length = 8 cm, width = 5 cm, height = 4 cm. What is its volume?

3. A water tank is shaped like a right prism with a triangular base. If the base of the triangle measures 6 m, height of the triangle is 4 m, and the height of the prism is 3 m, what is the water tank's volume?

4. A cistern shaped as a rectangular prism has dimensions of 2 m length, 1.5 m width, and 1 m height. Calculate the volume of the cistern.
