Contact metamorphism occurs when magma inside the Earth intrudes existing rock. The rock that comes in contact with the magma is superheated and new types of rock are formed.

Mineral grains in shale become foliated as they flatten due to heat and pressure and form slate.

The four main minerals that make up granite are feldspar, quartz, mica, hornblende

Regional metamorphism occurs at the boundaries of plates, where large areas of rock are deeply buried.

The nebular theory states that the solar system was formed by the collapse and flattening of a nebulae due to gravity. This led to the creation of the sun, planets, and other components of our solar system.

The sun is the central point around which all planets in our solar system travel.

In honor of International Podcast Day, Jared and Dani kick off season three of UEN Homeroom with a discussion on innovation during COVID. They discuss topics such as: the innovative ways in which Utah teachers are instructing students, what innovation looks like in our current classrooms, and how to help struggling teachers to adapt the "new now" they are facing in schools.

Illustrations show how genetic instructions carried on DNA are transcribed into RNA, leading to the production of specific enzymes that control the thousands of biochemical processes going on in living cells.

Illustrates the mechanisms of photosynthesis and cellular respiration. It introduces ATP, the universal energy carrier molecules that supplies energy hungry reactions, and shows the structure and function of Chloroplasts and Mitochondria, energy transforming organelles.

A good way to observe reproducing cells is to start with a sparse population of protozoa. A sample of water from a shallow pond, gutter, flowerpot, or ditch is a good source. Examine the sample through a microscope and look for microbes, specifically for dividing microbes.

Here students become acquainted with the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drink in fluids by pinocytosis.
