3. Knowing the difference between objects floating, drifting, and sinking.
4. Knowing the application of Archimedes' law in everyday life.
5. Knowing the procedure of a device by using the Law of Archimedes.

D. Activity Procedures
1. Activities Introduction
a. Motivation and apreciation
- Why the boat that framed from iron does not sink in water?
b. Prerequisite knowledge
- What is a floating, drifting, and sinking?
c. Pre-experiment
- Take care when using tools and lab materials.
2. Core Activities
a. Teachers guide students in forming groups.
b. Learners (guided by the teacher) discuss the understanding floating, drifting, and sinking.
c. Representatives of the students were asked to explain the definition of floating, drifting, and sinking.
d. Representatives from each group were asked to take tools and materials to be used in the experiment.
e. The teacher explain the procedures for experiment.
f. Students in conducting experiments in accordance with the steps outlined by the teachers work.
g. Teachers conducted experiments examining the learner, whether it is done properly or not. If still no learner or group that has not been able to do it right, teachers can immediately provide guidance.
h. Learners are guided by the teacher to discuss the density of objects on the state of floating, floating, and sinking.
i. Representatives from each group were asked to read out the conclusions of the experiments have been performed.
3. Activities cover
