Classroom debates are an effective teaching activity, especially for more advanced science students. Science has many controversial topics that can be discussed by students, who definitely have differing opinions. Topics can be chosen by the teacher or as a collaborative effort between the teacher and students. Participants are then divided into two groups in which they argue for or against a certain concept or policy in science. Debate encourages students to think more about scientific issues, and it also boosts their confidence.
Crossword puzzles can be used for revision, to enhance literacy and also to encourage interest in the subject. These activities are applicable for both younger students and older ones. Teachers can design crosswords and puzzles around a certain topic and allow students to work them out. Puzzles promote discussion of concepts in science within the classroom and are also appropriate when introducing a new concept. This activity can be done at the beginning or tail end of the class session.
Interactive experiments are at the core of science classes. These activities assist teachers to clearly demonstrate various concepts in all subcategories of sciences. Engaging students in the setting up and carrying out of these experiments will ensure that they retain the knowledge. It is important to ensure that all students participate in these activities by grouping them and allowing them to discuss among themselves.
The use of audio and visual activities such as movies in teaching science can be interesting for students. Sources such as TV episodes of "Nova," "National Geographic" and other science movies can be used to impart information while adhering to content standards. Information derived from visual and audio activities is easily maintained by students. These activities can also help them understand otherwise complex or abstract science concepts.
