5th grade science students have been busy. Following our chemical weathering lab, students noted the differences in weathering of a piece of chalk by vinegar vs. water. Continuing out study of the effects of weathering and erosion on the earth, students particularly enjoyed a weathering demonstration of beach erosion and some extreme video of glaciers.
For our 6th and 7th grade science students, it’s electric! This science class was involved in learning about sources and measurement of electric current. Through class instruction and various examples, they achieved an understanding of current, electromotive force, and resistance. The students were able consistently to calculate current and resistance using Ohm’s law. In addition, students have been able to draw schematics of series and parallel circuits and explain their different uses.
In our 8th grade science class, the last two weeks were used to study the laws of motion, calculating average speed, distance, elapsed time, and acceleration/deceleration. Demonstrations in class included difference between constant and variable speed.
Biology students have begun their study of human body systems. We have covered the skeletal system and are currently learning about the muscular system. Our study will continue with the circulatory and respiratory systems in the coming weeks.
