**Friday****, February 16th**

*F & G period*:* *Dr. Merritt began the class period by asking students to identify the three types of variables–*manipulated*, *responding*, and *controlling*–in a hypothetical biology experiment (LS12). After going over the answers in class, Dr. Merritt then asked students to do identify the variables in a hypothetical physics experiment (PS32). Again, we went over the correct answers in class.

*Homework: ***F & G period** students have been sent another Google Form by Dr. Merritt to their TASIS email address. This form asks students to identify the manipulated variable (MV), responding variable (RV), and three controlling variables (CV#1, CV#2, CV#3) for their *Brassica rapa* seed germination experiment.

*A period*:* *Dr. Merritt began the class period by asking students to identify the three types of variables–*manipulated*, *responding*, and *controlling*–in a hypothetical biology experiment (LS29). After going over the answers in class, Dr. Merritt then asked students to do identify the variables in a hypothetical physics experiment (PS32). Again, we went over the correct answers in class.

*Homework: ***A period** students have been sent another Google Form by Dr. Merritt to their TASIS email address. This form asks students to identify the manipulated variable (MV), responding variable (RV), and three controlling variables (CV#1, CV#2, CV#3) for their *Brassica rapa* seed germination experiment.

*F & G period*:* *Dr. Merritt began the class period by asking students to identify the three types of variables–*manipulated*, *responding*, and *controlling*–in a hypothetical chemistry experiment (PS22). After going over the answers in class, Dr. Merritt then asked students to do identify the variables in another hypothetical experiment, but this time a biology experiment (LS02). Again, we went over the correct answers in class.

*Homework: ***F & G period** students have been sent another Google Form by Dr. Merritt to their TASIS email address. This form contains a single practice problem involving other members of the Simpson family (Marge, Homer, and Bart). Students should try to complete the short-answer questions assigned to each of the three family investigations/experiments.

*G period*:* *After a short discussion of “variables”, students were asked to write definitions of the three types of variables–manipulated, responding, and controlling–in their lab notebook.

*Homework: ***G period** students have been sent a Google Form by Dr. Merritt to their TASIS email address. This form contains a single practice problem involving Lisa Simpson, who is working on a science project. Students should try to answer the five short answer questions included in the form. The goals of these questions is to see if students understand the difference between the three different scientific variables presented and discussed in class.

**Tuesday****, February 13th**

*Today in science*:* *After reading a short description of “variables” on another page of the SCIENCEsEDiment website, on a designated page of their lab notebook, students were asked to provide 1) definitions of the three types of variables, and 2) short examples of the three types of variables.

**Monday****, February 12th**

*Today in science*:* *In a shortened class (due to the all-school, International Week assembly), students were asked to 1) turn in their Seed Germination Research Project, and 2) continue their INV#6 pre-lab preparations in the lab notebook. The goal of today’s preparations was to become familiar with the first of three different kinds of investigation *variables*. Today, we discussed the “comparable” variable.

*Homework: *If you have not done so already, Dr. Merritt would like to remind students to be sure to print a copy of your SEED GERMINATION RESEARCH PROJECT to give to him as soon as possible. Also, be sure to include any Source sheets that show where you took the information included in your project.
