Lesson Summary

 

In this lesson students will lean and hands on to make  biological batteries on their own. They will follow the instruction on each step and examined by teacher and self-examine with each other to ensure each step is correct and well done.  Students will make 3 batteries and monitored by teacher to ensure each step is right and the batteries are made right and they are at working capacity and functional normal.  Then students will use multimeter to record the changing of the voltage and current of each battery over the time to collect real world data and experience the real power supply performance of biological battery by themselves. 

Essential Question 

 

• How is the voltage and current change of each biological batteries they made? 

• What is the maximum voltage and current of each battery? and Are they stable over time?

• Are the batteries they made all have the same performance? If they are different, why?

• What could be the possible ways to improve the voltage and current output of the battery?

• What they should do and should not do to improve the battery voltage and current?

 

Learning Objectives

 

  Students will be able to

• Engage in discussions about the importance of each step to make a successful battery.

• Discuss how each material and their performance impact the overall voltage and current of the battery.

• Discuss what they learned of the differentiate between a biological battery and the chemical batteries. 

• Explore the possible procedure to correct what they did wrong and how to improve it. 

• I identify the key components that determine the performance of the battery and why?
