Reflection: Real World Applications Lab Activity: Milk Makes Me Sick Investigation (Part 2 of 2) - Section 5: Close - The Meaning of Glucose


In my 15 years of teaching, I have found that students will nod their head to exhibit understanding even if they have no clue what is going on.  Ninth graders will try to take the path of least resistance and will attempt to dodge any extra attention on their lack of understanding.  PLEASE do not allow their head nod to equate to understanding.  It is crucial to "attempt" to check in with each student each day.  I know class sizes make this very difficult, but when you are introducing a new topic or leading into an assessment, it is imperative that teachers check for understanding with each student . . . and do not fall for the head nod!  A quick conversation or glance at their work will alert your attention to whether the student is on the right track or if the student needs academic intervention.  Take the time and check in with your students.  It will show them how much you care and it will provide you with a wealth of information to gauge student understanding!

Lab Activity: Milk Makes Me Sick Investigation (Part 2 of 2)

Unit 4: How It All Happens: An Introduction To Biochemistry
Lesson 11 of 11

Objective: SWBAT complete the laboratory investigation, construct an explanation of the enzyme activity , and hypothesize how this chemical reaction occurs in human physiology.

Big Idea: Uh oh - you just ate that bowl of ice cream, now what are you going to do? Is there enough lactase in your body to digest your lactose-rich dessert? Students will experience first-hand the chemical process of enzymes with this real-world experiment.
