  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.
