8th grade
1. We went over questions from P. 27 in the textbook. 2. Students will take notes on States of matter and Changes of state. (Attached below) 3. Students watched a video related to the content of the notes (plasma and change of state). 4. Circle topic: How things are going in class & lab partners (discussed as a class)

Today we will: 1. Go over the questions from "reaction in a baggie" 2. Complete the questions and gather class data from the "hot hand lab" (which we did yesterday) 3. Watch a video related to thermal energy and an endothermic reaction (posted below). 4. Questions on P. 27 (which will be attached below). Please answer the questions from Math, Analyzing Data questions (1, 2, 3, & 4) at the top of the page. Then, please answer questions (1,a,b,3a,b) in the Section 3 assessment. Let me know if you have any questions! [email protected]
Today students are doing a hot hand lab. Attached below is the set up. I can post data at the end of the day today or tomorrow for you to fill in the data table and answer the questions.
1. Today students identified properties and changes on page 23 in their Science notebook. Please identify the following as a chemical (C) or physical (P) property: 1. blue color 2. density 3. flammability 4. solubility 5. reacts with acid 6. melting point 7. reacts with water 8. odor 9. reacts with air 10. boiling point Please identify the following as chemical (C) or physical (P) changes: 11. NaCl (table salt) dissolves in water. 12. Silver tarnishes. 13. An apple is cut into pieces. 14. Heat changes H20 (water) to steam. 15. Baking soda reacts with vinegar. 16. Fe (Iron) rusts. 17. Pancakes cook. 18. A tire is inflated. 19. Food is digested. 20. Milk turns sour. 2. Students finished watching "The conquest of cold" (attached below). 1. Students added notes about exothermic and endothermic to page 20 in their science notebook (or page 21 in case you run out of space). (below) Exothermic: Energy is released into the surroundings as heat. As a result, the temperature of the surroundings increases. Endothermic: Energy is absorbed from the surroundings. As a result, the temperature of the surroundings drops. 2. Students took notes on physical and chemical changes (attached below) on page 22 in their Science notebook. Then, we answered the questions regarding physical and chemical changes. 3. Students did a lab. If you would like, you can mix baking soda and vinegar to get similar results. Always keep the ratio one-part baking soda to two parts vinegar. You add baking soda to vinegar. Then, you can answer the questions below on page 21 in your notebook:
1. Today we are practicing identifying physical or chemical properties. Please see the attached sheet, which will show some examples and then some for you to identify on your own. 2. Then, we did a demonstration of elephant toothpaste. 3. We watched parts of Mark Rober's elephant toothpast and then devil's toothpaste videos. These are included below.
1. Today students are going to take notes on Thermal Energy on page 20 in their Science notebook. The notes are attached below. 2. After that, students are going to begin watching "Absolute Zero: The conquest of cold" (35 minutes of the video today), which is attached below as well.
Today students are finishing the density of cubes lab. Next, we are watching a video on density (attached below). Last, we are taking notes on physical and chemical properties, which are attached below.
Today students will be doing the density of cubes lab. Attached below is how page 17 should be set up in your science notebook. Please use the values for mass and volume to calculate the density of each cube. Then you may use the density values to identify each of the cubes. I have also attached a picture of the cubes.
