Aiden learned about ions and molecules. He read that ions are charged particles bonded together, one metal bonded to one nonmetal atom. Conversely, molecules are neutrally charged atoms. We discussed and looked at the diagrams.
Matthew completed building his water fountain. We tested it out by injecting water into the tube with a syringe and making the paddle wheel spin under the water.
Matthew and I built several circuits with the circuit building kit. We built a siren, a music player you turn off by blowing into a microphone, a simple circuit, and a water alarm.
Matthew and I troubleshot an error in our engineering of the sketch machine and we corrected it. Matthew used the pulleys and knobs to draw various pictures. He read about how a sketch machine is similar to a computer using code and algorithm, and is similar in design process to a 3D printer.
Matthew constructed a sketch machine. He practiced his engineering skills by reading the instructions and following the diagrams. He learned how to create a pulley system.
Matthew continued adding components to his phantom projector to make vanishing images. He drew his own sun and moon vanishing image. He created a holographic image using a pyramid-shaped reflective plastic shape.
Aiden finished graphing his pressure vs. mass graph from our lab "Reload the Pressure." He took notes on the directly proportional relationship between mass and pressure, and the inversely proportional relationship between volume and pressure.
Matthew completed his phantom projector. He learned that the plastic rectangle reflects the ball onto the stage, making it appear like there's a ghost.
