How Crystals Form
In this class we will learn about geodes, crystals, and their connection to biology. The crystals in our geodes are made of quartz, it contains silica, a common mineral that is found in grasses and in most living organisms. Crystals are used in many of the electronics that we see and use every day, let's learn about crystals and then about other components that rocks contribute to biological life.
The piezoelectric effect converts kinetic energy in the form of vibrations or shocks into electrical energy.
Geodes are found in sedimentary rock and in some igneous rocks, we will be breaking geodes from Morocco, they are in sedimentary rock and have quartz crystals that are made of silica.
PHOSPHORUS Moves from living beings to Rocks
The geodes that we are using in this class are from sedimentary rock, this type of rock releases phosphorous as it breaks down, phosphorous is very important in biology. Here is a quick reminder of the phosphorous cycle:
Phosphorous may be released by LIGHTING
Phosphorus is needed for life as we know it, below is a link to an article about lightning and the phosphorus cycle.
PHOSPHORUS is in DNA and ATP
What does phosphorus have to do with DNA?
What does DNA have to do with an organism having different cell types?
What is ATP?
Where does ATP come from?
Where does the phosphorus for your DNA and ATP come from?
New DNA molecules are made by copying, using old DNA molecules as a template during cell division/ mitosis.
ATP: Adenisone TriPhosphate
How Fossils FOrm
Now we will learn about how biological creatures may be preserved in stone. After learning about what fossils are, you may select a fossil and tell us about it, what creature is it, what would be their ecologocical habitat and their niche?
What is your fossil's niche, habitat, trophic level?
After going around the class and talking about the fossils that each student chose, we will go outside and break pinatas that have been decorated by the students to look like cells and organelles.
Please complete the quiz that is on Canvas, we will have a review Kahoot during the next class.
