Mollusk Dichotomous Key
Animals
Ecology
Elementary School
Inquiry/Scientific Method
Middle School
In this lab, students will be introduced to the concept of a dichotomous key through the use of preliminary activities modeled by the teacher. They will then learn about the ecology and biology of selected marine mollusks, before putting their dichotomous key reading skills to the test on 8 or… read more of the article entitled “Mollusk Dichotomous Key”
Mystery of the (Hominin) Skulls
Evolution
High School
Inquiry/Scientific Method
In this laboratory activity students will examine nine hominin skulls for specialized features and take measurements that will enable them to determine the relatedness of these species. They will identify the placement of each specimen on a phylogenetic tree that also reveals the geological time frame in which each species… read more of the article entitled “Mystery of the (Hominin) Skulls”

Students will use LaMotte Test Kits to determine the concentration of dissolved oxygen (DO) in various water samples. The process involves adding some chemicals to the water to “fix” the free oxygen (O2). Once the O2 is fixed, they will add an acid powder, some starch, and titrate to determine… read more of the article entitled “Primary Productivity Lab- modified by Sean McGlynn”

High School
Inquiry/Scientific Method
Molecular Biology
Students will separate a mixture of proteins from skeletal muscle using SDS polyacrylamide gel electrophoresis (PAGE). PAGE is a powerful analytical technique having numerous applications in modern biology. Evidence for evolutionary relatedness amongst organisms can be determined using this technique. Suggested organisms to compare include various fishes, mammals, poultry and/or… read more of the article entitled “Protein Gel Electrophoresis”
Pseudomonas Labs
High School
Inquiry/Scientific Method
Microbiology
Plants
Module 1: This classroom activity demonstrates interactions between plants and specific strains of Pseudomonas (a plant-pathogenic bacteria). Students will design an experiment that demonstrates the specificity of the hypersensitive response. This serves as a starting point to learn the importance of model systems through comparisons of two pathogens. Both Pseudomonas,… read more of the article entitled “Pseudomonas Labs”

Slug Lab
Animals
High School
Inquiry/Scientific Method
Middle School
Students will investigate the food preferences of garden slugs (Arion subfuscus) using simple equipment including margarine tubs, graph paper, scissors, and common plants, both wild and cultivated. The exercise is genuine scientific research in that: a) the student devises his/her own “research question” about slug feeding behavior, and b) the… read more of the article entitled “Slug Lab”

Vocabulary and Story Writing- Karen Cook
2012 CIBT Alumni Workshop
Elementary School
Inquiry/Scientific Method
Middle School
The RAFT strategy (Santa, 1988) employs writing-to-learn activities to enhance understanding of informational text. Instead of writing a traditional essay explaining a concept learner, students demonstrate their understanding in a nontraditional format. This technique encourages creative thinking and motivates students to reflect in unusual ways about concepts they have read…. read more of the article entitled “Vocabulary and Story Writing- Karen Cook”
