ND RET Molecular Biology Workshop

This workshop evaluated various pre-packaged science kits for their effectiveness, engagement, and integration into the classroom curriculum. Participants collaborated to assess several kits, including Carolina Biological's "Understanding the Properties of Matter," which allows students to explore intensive vs. extensive properties and conduct hands-on experiments. The findings, shared on the ND RET Molecular Biology Workshop Resource Wiki, serve as a resource for other educators. Key evaluations suggested the kits were engaging and well-structured, with opportunities for modifications to enhance learning.

Presentation Transcript

  1. ND RET Molecular Biology Workshop Ken Andrzejewski- Marian High School Louann Kensinger- Riley High School Deb Semmler- St. Joseph’s High School Jim Keating- Washington High School

  2. Our Goal • To evaluate pre-packaged science kits we might want to use in the classroom • Are they cost effective? • Are they engaging? • Do they work? • How can they be modified?

  3. Our Strategy • To work through the kits as a group • To evaluate each kit • To determine if it would fit into the curriculum • To create modifications as needed • Post findings for others to use

  4. ND RET Molecular Biology Workshop Resource Wiki • http://retmbw.wikispaces.com • Contains science kit evaluations for 2009/2010/2011 workshops • Has a resource page for additional reference

  5. Kit 1: Understanding the Properties of Matter Carolina Biological Supply kit #251200 $149.95 refill #251250 $59.95

  6. Educational Purpose Students will • Investigate intensive and extensive properties • Explore differences between chemical and physical changes • Develop skills to design and perform experiments

  7. Activity 1 Students will devise and implement a logical system for organizing matter using materials from the kit. This included Properties of Matter Study Cards that the students could use to help them.

  8. Activity 2 Students will select 5 materials from activity 1 and explore eight properties of matter: Mass Reactivity w/ acid Volume Density Magnetism Appearance Conductivity State at room temperature

  9. Activity 3 Students will conduct eight different experiments and document some of the ways matter can interact. Experiments included reactions between: Yeast and hyrdrogen peroxide Silver nitrate and copper Sodium bicarbonate and acetic acid Iron and copper sulfate And others

  10. Evaluation • This lab is very engaging- there is plenty to keep students focused. • The worksheets and tables included were of good quality and very usable. • There is also an extension lab that allows students to design and conduct experiments that demonstrate the relationship between the intensive property of density and the extensive properties of matter. A very nice formative assessment addition.

  19. Other Activity Kits full explanations and evaluations can be found on the RET wiki Balancing Chemical Equations- as a balancing equation lab this one was not as advertised. But it did redeem itself as a types of chemical reactions lab. Reconstructing Atomic Thoery- the premiss was good- modeling erly atomic theory experiments but the demonstrations were juvenile and required too much work from the instructor.
