Answer: The choice of a submarine to either sink or float depends on the captain of that submarine. For a submarine to sink the captain just have to allow water to fill the water tank (lock), making the submarine more dense than the water it has displaced. For it to float, it just have to empty the water tank and allow air to fill it.
When a boat in a canal lock sank, the water level will rise, because the volume of the boat has displaced more water, and this displaced water will cause the water level to rise. The space occupied by an object in a water, is equal to the volume of water been displaced.

<h3>What is constructivism?</h3>
Constructivism is defined as "a learning method that maintains that people actively create or make their own education and that truth is determined by the learner's experiences."
Some characteristics of constructivism are-
- Arends (1998) elaborates constructivist principles by stating as constructivism believes in the learner's personal production of meaning through experience, but that meaning is determined by the interaction of past knowledge and new occurrences.
- The core notion of constructivism is that human cognition is created, that learners to build new information on the base of existing knowledge.
- The prior knowledge influences the new or modified knowledge that an individual constructs as a result of fresh learning experiences.
- Learners basically use their foreknowledge as a foundation & build on it with new information.
