Science Classroom Connection

Students are to complete the review questions in Chapter 1 that were assigned in class, namely, pages 26-27, #’s: 25, 34, 40, 41, 43, 49,  55, and 56.  These will be promptly answered and discussed in class upon the students return tomorrow.

Each student is expected to have completed and ready to turn in the lab report write-up on the paper towel activity, using the common steps of the scientific method. We will discuss students’ data, the analyses of their data, and verify their conclusions that should reflect the hypotheses of their experiments.

 Students will investigate four different types of paper towels to determine which paper towel is the most absorbent. They will use the standard classroom paper towel as their control. In a group of three, the students will state their objective, briefly research it, formulate a hypothesis and devise a procedure for their experiment. Once the procedure is verified by the teacher, the group can proceed with their experiment to collect, graph, analyze their data. Once the group is done, it need to draw its conclusion that shall reflect their hypothesis about the paper towels.

Homework: We will discuss the assigned graph that is based upon the ozone layer, and how the temperature changes affect it over a 12-month period by analyzing and correcting the critical thinking questions that are based on the graph.

Students will then team up in groups of three to devise a method to test which paper towel is the best to use by following the steps of the scientific method. Today, student will document their objective, hypothesis, materials, and procedure prior to proceeding to observe and collect their data.
