Using “Crazy Traits” kits, purchased via a Merrillville Education Foundation grant, students developed a model for how probability influences genetic variation. They discovered how genetically diverse the population can be even with just 14 traits.

“Crazy Traits” is a hands-on, modeling kit that engages students while teaching them the role that chance plays, in an organism’s inherited traits. Additionally, it gives students an opportunity to model things they can’t see, such as the genotypes of parents and the alleles inherited from each, and those of the offspring resulting from parent crosses. Student engagement level will increase because they will be having fun while using “Crazy Traits” to study how traits are passed from one generation to the next. They will benefit by seeing the results of genetics crosses that can only be done, currently, using paper-based activities. These 3-D models should significantly enhance understanding and retention of genetics concepts that are often difficult for students to comprehend.
Biology 1B students discovered that there are two types of traits: dominant and recessive. Using “Crazy Traits” kits, purchased via a Merrillville Education Foundation grant, students developed a model for how probability influences genetic variation. Students flipped coins to determine which alleles a Crazy Creature offspring would inherit from its parents. Students then built their creature and compared them to the creations of their classmates. They discovered how genetically diverse the population can be even with just 14 traits, all while using “Crazy Traits”! The program has been successful for two years now and continues to give Freshmen students a hands-on model that enriches their concept of genetics.

Every month, we are creating activities and projects to promote kindness, respect, empathy, and unity throughout the MIS building. We celebrate every month with the “Act of Kindness MVP” award.
Approximately 100 families attended and participated in a variety of STEM activities. The purpose of the program was to introduce our parents to the engineering process and the new Makerspace Room at MIS.
