This lab demonstrates both the specificity and denaturation of the lactase enzyme. This is a true kitchen-chemistry lab- the only required materials are skim milk, lactase tablets (from the pharmacy aisle), and glucose test strips. The lab is fully editable. To simplify the lab or to shorten it for just one class period, I suggest removing "Part 2". A pre-lab worksheet, teacher preparation notes, expected results, and possible modification/extension are included.

This worksheet is great for an overview of transcription and translation. The first portion reviews how mRNA is made from DNA and allows the students to create mRNA from a template DNA strand. The second part utilizes the codon wheel to translate mRNA into protein. The last portion reviews both skill sets, from DNA to amino acid chain. It can easily be modified by filling in some of the bases/codons to get the students started on the right foot! Answer key is included.

11 page PDF that contains tiered labs for a lesson about the molecules of life. It includes an advanced version, regular/CP version, and mini-lab version designed for a 42 minute period. A pre-lab worksheet and reinforcement sheet is also included. Download my free macromolecules PowerPoint to introduce this topic!

This handout provides guidance for forensics science students to create a case study on a case of their choice. Useful links are provided to assist students in selecting a case. The requirements are outlined, and an assignment rubric is provided. I have also included a modified version. This is a Word doc, so it can be edited to suit your needs.

This worksheet accompanies my "Cell Differentiation & Stem Cells" PowerPoint presentation. It is a sheet students for students to complete as they engage in the presentation.
