Figures 1 and 2
We used the PhET semiconductor simulator to explore how doped semiconductors function in diodes. By switching between N-type and P-type dopants, we observed the resulting changes and developed theories to explain the behavior we saw.
Semiconductor Front-end Manufacturing Activity:
Figure 3
Figure 4
Figures 3 and 4
Using Tinkercad, we designed a basic circuit and explored how components like transistors and resistors regulate current flow and protect the LED. When we transferred the design to a physical breadboard, we ran into issues caused by a faulty paperclip connection. We resolved the problem by wiring directly to the negative terminal, and the circuit functioned properly—lighting up the LED as intended.
College Readiness Circuit:

Figure 5 and 6
We utilized AND and OR logic gates to design a circuit that models decision-making factors affecting college admissions. This hands-on approach enhanced our understanding of the functional differences between the two gate types and clarified their appropriate use in logical circuit design.
Every Circuit Rock-Paper-Scissors:
