HOWLs Target:

• I keep working until the task is complete.

Agenda

• Warm-up: PRETTY PICTURE FRIDAY
• 
• The Antennae galaxies, viewed in the sharpest-yet image of this merging pair of galaxies. During the course of their collision, billions of stars will be formed. The two spiral galaxies, about 45 million light-years from our solar system, started to interact a few hundred million years ago, making the Antennae galaxies one of the nearest and youngest examples of a pair of colliding galaxies. Nearly half of the faint objects in the Antennae image are young clusters containing tens of thousands of stars. The orange blobs are the two cores of the original galaxies and consist mainly of old stars criss-crossed by filaments of dust, which appears brown in the image. The two galaxies are dotted with brilliant blue star-forming regions surrounded by glowing hydrogen gas, appearing in the image in pink. #

• Composting KWL
• With the tubes made from 2L soda bottles we will be looking at what happens to matter during decomposition. Are the changes that happen physical changes or chemical changes?
• To answer this, everyone needs to have an understanding of composting.
• On the worksheet: (use the containers of before and after compost to help)
• Step 1: write everything you already know about compost and composting. This may be a short list.
• Step 2: make a list of questions about compost. Minimum 5.This list can include anything from "How does composting work?" to "Does compost smell?
