September 22nd - In Class and Homework

Today was a practice day for the enzyme lab. We used the hand held data collectors, oxygen sensors and potato for the enzyme (hydrogen peroxide is the substrate). At the end of class, an introductory reading for the lab (which we will do Thursday) was handed out to be read for homework. Also, the Test for Chapters 4 & 5 (a summative assessment) will be next Tuesday.

Today was our second day of using the toobers - each student was given a 9 or 10 amino acid segment of the human alpha hemoglobin molecule. The class then used the guidelines for the formation of tertiary structure to build the entire molecule. The remainder of the period was spent working on a protein (structure and function) concept map. The homework is to complete this map.

We introduced the topic of protein structure by viewing the campbell web site (on student computers) and paying close attention to 5.4 #2 (protein structure). Secondary and tertiary structure are the most challenging to learn, so the students were encouraged to spend more time on theses topics. After finishing this, the students completed a rather simple toober activity. A chapter 5 study guide was handed out at the end of the period, and the homework is to read page 28 and 29 of this study guide, and to complete interactive questions 5.6, 5.7 and 5.8 on these pags

We had shortened periods today due to early release (approx 34 min per class). The food labs (table and answers to 3 questions) was collected. The majority of the period was spent viewing a powerpoint presentation involving carbohydrates and lipids with the teacher pointing out the most important information (students were monitoring their study guide on the same topics completed last Friday. The homework is to read section 5.4 - which deals with protein structure and function

Day 2 of the food lab today. The rest of the tests were performed, and then a good cleanup. Homework is to complete the lab questions.

September 14th - In Class and Homework

Today we began a food (organic molecule) lab. We are testing for the presence of 2 types of carbohydrates, proteins and lipids in a variety of food. Today was primarily a set up day (preparing the food samples, etc.). Two handouts were given - the lab instructions and the data table / 3 questions. We will finish the data collection tomorrow. The lab will be due Wednesday (students were encouraged to begin question 1 tonight).

September 11th - In Class and Homework

Time in class today was used to work on a handout dealing with carbohydrates and lipids (from the reading last night). The homework was to complete any unfinished in class work. An expectations sheet for chapters 4 and 5 was also passed out to the students
