Accidents involving electricity can cause shock, burns, and even death. Reviewing and following a few basic rules will help you improve electrical safety when working with hot plates, electrophoresis equipment, power supplies, Van de Graaff generators, etc. Continue reading
This is a fun and challenging inquiry activity in which students construct circuits with specific requirements.

The Focus on Inquiry:
This guided inquiry project was designed to provide students with the challenge of creating a fully-electric car. The students were provided with a motor, photographs of sample electric cars, an outline of the criteria their car was to meet, and a rubric as a marking scheme.
The Inquiry Project:
The project was discussed and proposed at the beginning of the physics unit of study in grade 9 applied science.
Students were tasked with completing three main components:
I. A Thought Book
This is where the students formulated questions, made hypotheses, and made predictions about their project prior to beginning construction of their electric car. The Thought Book took the form of pre-formatted Google Slides that the students shared with the teacher and the rest of their peers. The students completed different ‘pages’ of the Thought Book as they progressed through different stages of the inquiry project. They also used the Though Book to gather, organize and record information during their ‘build days’.
II. A schematic of their circuit
This is where the students communicated their understanding of how electricity moves through their circuit. Students were asked to communicate their results in appropriate key terms (ie. source, load, conductor, insulator, switch).
III. Reflection questions
These questions were designed to have students reflect on their learning, analyze their outcomes, describe their challenges and how they surmounted them.

Students use electrical devices every day. An essential safety component of any electrical device is the fuse. Demonstrate what it means to “blow a fuse” and show why fuses are important safeguards against electrical fires. Courtesy of Flinn Scientific Canada.
This very simple to perform demo can be made very memorable by ensuring the students see it as a discrepant event. Students are expecting to see a free fall but instead see a low terminal velocity with no obvious source of friction.
