Assessment resource Filling glasses: create: assessment

TLF ID L9780

Test your understanding of the relationship between the shape of a glass and the level of liquid in the glass as it fills. Show your understanding by creating irregular-shaped glass containers to match line graphs that represent the filling rates. For example, create a composite shape container to match a graph consisting of a straight line section and a curve. This assessment object is one in a series of two objects.
