Day 98: Structure of the Sun January 29, 2007

Posted by Admin in Astronomy.

sun.jpgThe sun and its structure and processes were the subject of today’s notes and discussion. After discussing a diagram of the layers and surface features of the sun, we discussed why the sun shines: nuclear fusion. Tomorrow we will begin construction of the Sun models. These models will take many forms: some will chose to complete a labeled drawing, others will work on construction-paper diagrams, and others still will construct 3D models with styrofoam balls or even cut-apart basketballs! Each model must include the 6 layers of the sun and the 3 surface features: sunspots, solar flares, and prominences. We will continue work on these on Wednesday with test review on Thursday.

Today we also turned in the Stellar Life Cycle projects. The planet flashcards were also graded. The test has been moved from Thursday to Friday; the after school study session has also been pushed back one day: from Wednesday to Thursday (3:05-4:00). The test study guide is available now in class and here.
