Chemistry class-one of the Blackboard functions
Before the chemistry class involved experiments, the class representatives had to rush to the laboratory to move equipment before class, and then the teacher would personally demonstrate the experimental process during class. When the class is over, the class representatives have to tidy up the lab supplies and wash the test tubes.
Even so troublesome, whenever the chemistry teacher stood in front of the podium to demonstrate an experiment, some classmates sitting a little bit in the back chanted "Invisible".
But now, with the help of the smart touch-screen blackboard, the chemistry teacher can directly move the experiment to the blackboard.Interactive Blackboard Even the liquid in the test tube is made extremely lifelike, and you can even zoom in and out at will, so you don't have to worry about the students in the back row not seeing it anymore!smart touch screen Teachers also only need to move their fingers to complete the entire process of the experiment.
