Today we worked on finishing notes for changes of state. We then discussed freezing and melting before getting back into the discussion about bubbles. Bubbles contain both the liquid and gas phases. You have to blow (gas) through a liquid layer to create a bubble. This also led us to a discussion about surface tension and how beginning with a rectangular frame will still yield a round bubble. Check out the notes below if you missed them as well as some bubble recipes to try over fall break! We will be doing Data Set Question 6 on Wednesday when we get back. The outline is posted below!
