Presentation transcript:

Analyze It! 1.Scan the QR code posted at this station. 2.Closely observe the photo on your iPad. 3.Write what you observe in this photo. 4.Connect your observations to what you know. Is what you see a physical change or a chemical change? How do you know?

Read It! 1.Get a copy of the Physical Changes and Chemical changes pages. 2.Carefully read each page, and record at least three important notes about physical changes and three important notes about chemical changes.

Tech It! 1.Scan the QR code posted at this station. 2.Watch the study jams video. 3.Click the “Test Yourself” button and complete the test. 4.Take a screenshot of the results of the test. 5.If you didn’t do well, feel free to try watching the video and taking the test again!

Explain It! 1.Read and make observations about the scenario and data in the Explain It data table. 2.Record three observations about the data. 3.Read the following information and answer the questions to form your conclusion. Icy roads can be very dangerous for drivers. In the winter, cities put salt on icy roads. Why would they put salt on the ice? What happens to the salt? What happens to the ice?

Sort It! 1.Get a bag of Sort It cards and make sure there are still 8 in the bag. 2.Sort the cards as Physical Changes or Chemical Changes. 3.Take a picture of the sorted cards. 4.Check your answer using the answer key. 5.What is a physical change? What is a chemical change? Draw a picture and write a brief paragraph to explain your answer.

Explore It! 1.Gather supplies: sugar cube, spoon, and beaker. 2.Record a video of you completing steps 3 and 4. 3.Hold a sugar cube over the beaker and rub it between your fingers until the pieces of sugar have all fallen into the beaker. 4.Add 500 mL of water to the beaker. Stir with the spoon until the sugar dissolves. 5.Answer these questions: Was breaking apart the sugar cube a physical change or a chemical change? Was dissolving the sugar a physical change or a chemical change? How do you know?

Explore It (Part 2)! 1.Gather supplies: 2 pennies, beaker, small pour of vinegar, ½ spoonful of salt, paper towel 2.Record a video on your iPad of steps Pour vinegar into beaker and mix in salt. 4.Add both pennies to vinegar mixture and wait 10 seconds. 5.Take both pennies out. Place one penny directly onto paper towel and rinse 1 penny under water. 6.Describe what happened to the penny that was placed right onto the paper towel. Describe what happened to the penny that was rinsed. Classify each as a physical change or a chemical change. How do you know?
