Hands on projects offer one of the greatest learning tools teachers can use with their students. While the students may remember little of what you say, they will remember these projects for many years. Consider these five physics products that are sure to get the attention of any student.
Strong Magnet sculptures allow the students to build using magnets. By using magnets with marked polarity, the students quickly learn that effective building requires attaching the N pole of one magnet to the S pole of the next. This can convert the magnetic building project into a critical thinking exercise for students of any age. The hands on experience is a great intorduction to magnatism.
Magnetic viewing film has a fluorescent green field that shows the magnetic field of magnets by turning darker or lighter in accordance with the directions of the field lines. The film is much easier to use than iron filings over paper and offers much easier cleanup. In addition, students love the crazy designs the magnetic fields create, adding to their retention of this unit. Such experiences prepare the class to learn about magnets, generation of electricity and the magnetic poles of the earth.
A working wood catapult can be used in teaching of math, science and history in a combined unit. The catapult teaches creation, destruction and motion in a single lesson. Students learn how levers increase force and how speed and mass work together to create momentum, which can be used for good or evil.
The bottle balancer illusion offers an effective method of teaching students the principles of gravity. A full two-liter soda is suspended in mid air using a board with a hold drilled through the center. Onlookers will believe there is some trick to this illusion, but it works anywhere gravity is present. This demonstration can help students to learn why a lower center of gravity makes balance easier when riding a skateboard and how the principle makes cars that are lower to the ground safer.
A hand boiler offers an excellent way to demonstrate the principle known as Charle's Law. The liquid in the lower bulb boils due to the heat generated from the palm of one's hand. This causes the liquid to spiral up the tube. Once the device is removed from the hand, the liquid will return to the bottom flask as the glass cools to room temperature. Students learn about the transfer of heat, boiling point and phase changes as liquids turn to vapor.
These experiments and demonstrations offer a great way to motivate kids in a classroom to interact and learn. Choose these demonstrations as a great way to open discussion and prepare the class for learning. These engaged students show better performance on standardized tests.
