Science Classroom Observation  Grades 5-10 (with adaptations) ** Goal ** : The students will make and explore the properties of a strange substance using the Scientific Method. ** Background: ** The term “Oobleck” is derived from the book **//Bartholomew and the Oobleck//** by Dr. Seuss that was shared with the class prior to this activity. Experimenting with Oobleck is much more than having fun with a weird substance. As students participate in this activity, they will develop important skills in scientific observation. Scientists use similar processes to investigate quarks in the nucleus of the atom. ** Essential Question ** : In what ways can matter change? ** Materials ** : ** Objectives: ** In this activity students will: ** Performance Indicators: ** v Mixtures are physical combinations of materials and be be separated by physical means. v During a chemical change, substances react in characteristic ways to form new substances with different physical and chemical properties. (Examples: burning of wood, cooking of an egg, rusting of iron, and souring of milk). ** Bell Work: ** As the students enter the room, they will do a quick warm up activity that refreshes them on the properties of liquids, solids, and gases. ** Activity: ** After viewing a Power Point presentation on the Mystery of Oobleck and learning of their “mission”, students will begin the Oobleck Activity. After the completion of the activity, we will reconvene to review what ingredients were in Oobleck, and will discuss what our findings were. I will share with the students that Oobleck is actually a **colloid**; a mixture of two or more substances that are not chemically bound to one another and shares properties of both a solid and a liquid and cannot be categorized as either. ** Assessment/Closure: ** Throughout the activity, I will be observing students as they work, and assessing their progress. Students will complete their labs, check them over using their lab template rubric. Students will have a follow up assignment for homework entitled “**//Reading About Changes”//** that they will be given after tomorrow’s follow-up lesson. In tomorrow’s class, we will also be doing a writing activity entitled **//“Writing About Physical Properties”//** that will have the students write a short essay about their favorite food. The ticket out of the classroom will be the homework assignment that the students completed for today.
