Step 1: Please watch the following video about how to make an electrical circuit: what materials are needed, how to connect them in order to function.
Step 2: Game time: you will find on the screen some elements necessary to make an electrical circuit. Use them and make the circuit work as you have seen in the video. If necessary, watch the video again.

Watch the video:

0:20- Connect the positive of the battery to the positive (longer leg) of the LED and negative to the negative (shorter leg) of the LED
0:37- The LED should light up
0:44- Connect the negative terminal of the first LED to the positive terminal of the other
0:58- Series circuit: Connect the positive terminal of the first LED to the positive end of the battery and the negative terminal of the second LED to the negative end of the battery
1:09- The LEDs should glow, but rather dimly
1:18- Parallel connection: Connect the positive end of the red LED to the positive end of the green LED and the negative end of the red LED to the negative end of the green LED
1:50- Connect the positive and negative battery terminals to the positive and negative terminals of the red or green LED respectively to complete the circuit
2:06- Both LEDs should light up brightly

Level 1 : Basic circuit - Connect the given elements

CONGRATULATIONS! VERY WELL DONE!

WELL DONE, BUT THIS IS NOT THE RIGHT ANSWER! TRY AGAIN!

CONGRATULATIONS! YOU JUST FINISHED THE LAST LEVEL!
