Determine the voltage of the battery based on the colors of the resistors and the current in a combination circuit.

Determine the internal resistance of a battery based on the graph of terminal voltage vs. current. Also find the maximum current and the electrochemical potential.

Determine the voltage of the battery based on the colors of the resistor and the current in the circuit.

Determine the voltage of the battery based on the colors of the resistors and the current in the parallel circuit.

This task uses a situation that is familiar to young scholars to solve a problem they probably have all encountered before: How long will it take until an electronic device has a fully charged battery? Given data, students perform a...

This task looks at how long it takes for a laptop battery to fully charge. Students make a scatter plot of data, draw a 'line of best fit,' and predict the time it will take to reach a full charge. Aligns with 8.SP.A.2.

Kids learn by experimenting with science. Project on electricity with homemade batteries.

What are batteries? Explores the difference between batteries and cells, how batteries work, and the different types.
