Springlake-Earth HS Science Update

Always Question, Always Wonder.

8th Grade

This past 6 weeks has been a very busy time for 8th graders. When students started back after Christmas break, they jumped right into earth science. Students began learning about convection currents in the atmosphere and oceans and how that leads to different weather systems. Reading weather maps is now a breeze for these kiddos.

After the unit of weather, students dove into plate tectonics and the land formations that occur because the movement of the plates. Students learned about the three types of plate boundaries: Convergent, Divergent, and Transform.

After learning about the different geological features created by plate tectonics, students learned how to read topographic maps. Topographic maps illustrate the different land features created by our ever changing earth.

The 5th six weeks is going to be an even busier time. We will be looking into space science, organisms and their environments, and finally starting our STAAR review.

After Christmas break, the IP&C students begun the integrated physics part of this course. They started by learning about motion and the different parts of motion. This included: acceleration, centripetal motion, speed, velocity, and frame of reference. With each of these topics the students had to learn a new mathematical formula on how to calculate each one.

After students learned the different calculations for motion, they began to explore Newton's Laws of Motion more specifically. The students broke down each of Newton's 3 Laws and became little experts on what they mean.

They finished the six weeks with momentum (no pun intended). Students can calculate momentum, and now they understand what the Law of Conservation of Momentum is.

Biology class learned about ecosystems. An ecosystems a biological community of interacting organisms and their physical environment. An activity they practiced was the process of random sampling, a method used by scientists in estimating population numbers in a specified environment.


Chemistry students started the second semester by learning about the Mole. These students have had their serious thinking caps on through this entire unit. They are now able to calculate molar mass like pro's and even set up and calculate Stoichiometry problems like little Einsteins.

Students have had lots of fun using Avogadro's # (a.k.a avocados #) and the different particles that it represents. 6.02 X 10^23.

Chemistry students have come to the conclusion that this part of the class is not difficult, but there are just multi-step problems that require each part to be put into the correct place. Students have practiced all of this enough that I bet they could write the stoichiometry formula down with their eyes closed.

This upcoming six weeks we are going to explore gases, solutions, acids and bases.

Principles of Technology

Physics explored waves. They learned about Hooke's law, and how to calculate wave speed. They performed an activity illustrating simple harmonic motion with their labquest apparatuses. Up next... sound waves!
