Lesson 3 Mass Wasting and Glaciers – We added Chapter 3 Lesson 3 vocabulary to our science notebook. Then we learned about mass wasting caused by gravity and rain.
We completed a quiz on chapter 3 lesson 1. We learned about erosion by flowing water. Young streams in mountains have the greatest energy and create V-shaped valleys. Then we learned that slower moving, mature streams erode the sides more than the bottoms of their channels creating meanders. Next we learned about coastal erosion from longshore currents.
We learned that landforms created by erosion such as the Painted Desert of Arizona contain several layers of different materials. Then we looked at some national parks with unusual landforms and learned how the formations occurred.

Science Enrichment:
The Snapper -
Gracyn and I watched some views of birds dancing, then we continued with the project we started a week ago. This time the subject was a red snapper fish. We discussed how her family had caught and eaten many snapper. We watched a video from the reef organization, showing scientists counting the fish species found in the Bahamas. She used several warm colors to make her snapper look ‘handsome’.
We conducted an experiment with a pH indicator to determine whether substances were acidic or basic. Then we explored why stronger acids such as acid rain increase chemical weathering of rocks on Earth’s surface. We explored why the amount of surface area is related to the amount of chemical weathering as well.

The Octopus -
Gracyn and I watched the brain-pop segment on dolphins, and discussed the vocabulary words to which she was introduced. We then started a project of completing a coloring booklet on the animals of a coral reef. She chose the octopus to start, and so we watched a video on the octopus. We discussed how they could be any color, and change both color and texture at will. She decided to color the octopus a rainbow of colors to represent this process. We worked at not rushing the process and to keep inside the lines.
We reviewed that the rock cycle is the series of processes that transport and continually change rocks into different forms. When magma cools beneath Earth’s surface or lava cools on Earth’s surface, mineral crystals form changing the material into igneous rock. Then we learned about uplift which is a process that moves large bodies of Earth materials to higher elevations. Uplift builds mountains after millions of years.
