In this lab, students will experience the interaction of charged objects. Students should realize that the phrase “opposites attract” isn’t exactly correct. It is not just positively and negatively charged objects that…

This inquiry activity is performed before students understand the difference between current and voltage. Students also determine the procedure themselves and design the data chart and graph on their own. This makes it…

This activity is inquiry-based in that students will perform the activity before they formally learn about how objects can become charged with static electricity (induction, contact, etc.). This will allow the teacher…

The number of batteries used in this lab is determined by the type of lightbulbs that are used. A 3 V lightbulb will require two batteries. Students should perform this activity after being instructed how to use the…

An LED should never be connected directly to a battery or it will be damaged. A current-limiting resistor must be attached to either leg to prevent this damage. The value of the resistor will depend on the battery that…

This lab is between a Level 2 and Level 3 inquiry activity in that it should be assigned after students understand acceleration but before they learn about the acceleration gravity. Because there are many sources of…

In this investigation, students will construct electromagnets and test to see which variables make them stronger. Although elementary and middle school teachers are expected to have done this activity with their classes…

This activity will introduce students to the idea of magnetic field lines—a concept they have probably encountered but may not fully grasp. Completing this activity and reading the corresponding background information…

Resistance is how much an object resists the flow of electrons. This depends on the material (its resistivity) and the size and shape of the sample being tested. In this lab, students will determine whether resistance…

Students can easily see what series resistance means in this activity. Students are sometimes confused by the fact that all real resistors are the same size even when they have far different values. It is recommended…

Students will measure the resistance of resistors that they have drawn on paper with a graphite pencil. They will then connect two resistors in parallel and measure the resistance of the combination. In this activity,…

It is important for students to understand how resistors, capacitors, and batteries combine in series and parallel. The combination of batteries has a lot of practical applications in science competitions. This lab also…

This lab is not an inquiry activity. There are some students whose reaction times will not allow them to catch a 12 inch ruler. They may use a dowel, stick, strip of cardboard, etc. Although the students are led to…
