Electric Circuits
Experiment with electric circuits and conductivity. Young scientists will model and discuss how an electric circuit works. First they will draw a model of the flow of electrons and then build an actual circuit. Finally, they will explain...
Curated OER
Resistor and Resistance
Students explore electrical resistance through various experiments. In this physics lesson, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a resistor.
Curated OER
Thermoelectricity
Students conduct a series of experiments on thermoelectricity. For this physics lesson, students investigate how thermocouple works. They determine the voltage generated when different conductive materials are held at different...

Let's Light up a Light Bulb
Third graders investigate electricity. In this electricity instructional activity, 3rd graders observe a familiar battery-operated toy and brainstorm reasons why and how the battery works. Students work in pairs to explore batteries,...
Curated OER
pH Lab
In this pH worksheet, students experiment with dilutions of acidic solutions to test for the pH using cabbage as an indicator. They then test a variety of substances for pH. On day two of the lab, they test conductivity of solutions and...

Lab 23-Follow Up Questions-Conductivity
In this conductivity worksheet, students answer post lab questions about substances that transferred electrons resulting in electricity flowing through the conductivity leads use to test each substance.
Curated OER
Electricity: Will It Conduct?
Young scholars build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.
Curated OER
Metals and Non-Metals
In this metals and non-metals worksheet, students read an explanation of metals and non-metals and then answer three questions for each about conductivity and form.
Curated OER
Elements, Compounds, and Mixtures
For this elements, compounds, and mixtures worksheet, students answer questions about the properties of elements, mixtures, and compounds. Students identify the physical changes that is made to a substance to determine if it is an element.
Curated OER
Conductivity
Students work together to create a simple conductivity tester. They discover the difference between conductors and insulators. They test different types of materials for their conductivity as well.

Teaching about Increased Conductivity: Are Culverts The Culprits?
High schoolers encounter the complexity of identifying the cause of unusual variations in WOW conductivity data. They propose theories on why there was a sudden increase in conductivity in Ice Lake, Minnesota during July of 1998.
Curated OER
Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...
Curated OER
Arranging the Elements
Young scholars describe how elements are arranged in the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their location in the periodic table. Finally, students identify and describe the...
Curated OER
Periodic Table
Learners relate to the idea of periodicity & give example of other periodic events and identify and use the periodic table as a useful resource. They also identify the relationship of elements to certain groups & periods &...
