주간 과학 랩: 실습 실험

During the weekly science labs, we will explore a variety of scientific topics with hands-on experiments. We will experiment with Physics (Aerodynamics, Buoyancy, Levers & Planes, Magnets, Pendulums, and Hydraulics), Chemistry (Biomolecules, Temperature & Density, Conductors, Electroplating, Proteins & pH, Mixtures, and Titrations and Molar Solutions), Biology (Concentration Gradient, Plants,  Microbiology, DNA and Genetics), Anatomy (Vision, Touch, Sound, and Taste & Smell) and Earth Science (Barometer & Hygrometer, Filtration, and Water Cycle & Air).  

Depending on how the experiments run, there is a possibility the lab may run past the end of the session. 

Please note some of  these labs are similar to the experiments in my week long Science Lab Camps.

Please see the learner supply list tab below.  

This is a tentative schedule, dates are subject to change.
