哦，化學樹，哦，化學樹！利用科學製作節慶裝飾品 (Flex)

In this class, we will use chemistry and creativity to make four different holiday decorations that you can hang on your chemistree, in your windows, or anywhere that needs a festive decoration!

In class 1, we will learn about solubility and crystals before making two different types of sparkling crystal ornaments. 
In class 2, we will learn about chromatography before using what we've learned to make colorful bulbs or snowflakes with chromatography patterns. 
In class 3, we will learn about polarity and viscosity before using what we've learned to choose materials to make a snow globe.
In class 4, we will learn about polymers before making our own milk plastic ornaments and slime-filled ornaments.

How class is structured:
Each week in the classroom several posts will be made. 
Post 1: all of that week's videos and PDF files will be uploaded. The first video will explain that week's science concept, while the second video will demonstrate how to complete that week's activity or experiment. 
Post 2: students will be asked to share their predictions and observations from that week's activity and upload a photo or video of their final results from that week. 
Post 3: discussion question. Students will read and reply to the discussion question, which will tie together the science that was talked about that week and the actual experiment that they did. They will be expected to provide either a written or video reply to contribute to that week's discussion.

Teacher interaction:
In addition to uploading the content each week and providing timely responses to questions about the activity procedures, I will provide comments on student predictions and observations and ask follow-up questions as necessary. I will also moderate the discussion question by answering questions, providing feedback, and steering the conversation in a way that encourages collaborative learning and community building.
