Estimate the Area of your Classroom Wall
Use a measuring tape to get height and width.
Multiply to get area.
What if you don’t have a tape? Can you estimate using A4 paper or your hand span?
Mystery Object Volume Challenge
Each group receives a wrapped irregular object (pebble, bolt, rubber stopper, etc.).
Use a measuring cylinder filled with water at a known level (e.g., 100 mL).
Carefully place the object in the water and record the new water level.
Calculate the volume displaced
