Today we worked on lighting LED’s up with circuits and switches.  First, we used a 3v battery to light an LED up.  We added a switch in and it was quite simple.  Next, we used a breadboard to connect everything.  This task was harder because you had to line up all the strips, but not too bad.  Then, we connected a 9v battery and a resistor into the circuit on the bread board.  The hardest part was making sure that we had a complete circuit.
