Animals: Structure and Function

Groups of organs with specific structures and functions work together as systems, which interact with other systems in the body.
The development and uses of technology to maintain human health are based, in part, on the changing needs of society.

Current, Voltage, and Resistance in Circuits

In today's class Grade 9s conducted their final investigation with electrical circuits. They compared voltage, current, and resistance in series and parallel circuits by setting up circuits with two resistors in series and then in parallel. They measured the voltage and current across and through each resistor in each setup. They also measure the resistance of the resistors in each set up. The analysis of this investigation is due tomorrow.



Homework & Reminders:
  • The Effect of Increasing the Number or Loads in a Circuit Analysis is due tomorrow
  • Complete Q 1 - 7 on p. 575 of the textbook - we will take this up tomorrow
