The article reports that simple, straightforward problems that provide hands-on experience and make real-world connections are the best way to introduce science topics to school students. These discussions lead students to discover scientific principles on their own. Density is one of the most difficult concepts for students to grasp. Although most students can memorize its definition, when they come across a problem that requires deeper understanding, even the word density triggers anxiety. An example from day-to-day experiences can be very effective. For example, a teacher can ask students to explain whether a ship can transport the same quantity of sand as it can transport oil. To develop better understanding of density, students should be provided with different measuring devices. Although it is easy for students to memorize that a fire needs heat, fuel, and oxygen to burn, a hands-on experience makes this lesson much more memorable. These are some of the innovative ways to involve students in a learning process.
