African American Scientist Series
Dr.Walter Lincoln Hawkins
Preparation of SLIME Classroom Chemistry Kit
Dr Walter Lincoln (Linc) Hawkins was the first African American to join the Technical Staff of the Bell Labs in 1942. He worked developing plastics to replace lead and rubber sheathing used for insulation of wiring. After a long and distinguished carreer with Bell Labs he retired and continued in service to the community encouraging minorities to study chemistry. He was recognized internationally for his contributions to technology, engineering and polymer chemistry. The demonstration of polymer (SLIME) science could be a first step to follow in his foot steps...
Everyone loves to make slime! Two solutions are combined to form this unique polymer, an example of the type of huge molecules. The preparation of slime is a great example of a chemical change. The large polyvinyl alcohol molecules are linked together (crosslinked) by the boron atoms in sodium tetraborate to create a product we call SLIME. The addition of food coloring turns the slime any color you choose. Kit includes enough polyvinyl alcohol and sodium tetraborate for 4 classes of 24 students, working individually, to make slime.
Suitable for Grades 3-10.
Materials included in this Classroom Kit include:
350 ml of 4% solution of sodium tetraborate decahydrate
- Biography sheet for Dr.Walter Lincoln Hawkins
- 1 set of food coloring agents
- 1000 ml polyvinyl alcohol
- 30 sealable plastic sandwich bags
- 2 -10 ml graduated cylinder or pipet
- Procedural instructions
- Teaching tips for the instructor
Kids LOVE This One!
In 1996 MacNan Biologicals set out on a mission to meld historical facts with scientific exploration focusing on the accomplishments of African American scientists. MacNan Biologicals, located in historic Birmingham, Alabama enlisted experts in the fields of science and education to prepare these kits. The representative scientists selected were chosen for the significant accomplishments they achieved in their particular fields of expertise. It is our hope that the Focus on African American Scientists Series will motivate students to seek a greater understanding of science and consider careers on the scientific frontier.
MacNan Biologicals has also partnered with the Birmingham Civil Rights Institute to conduct seminars to teach teachers how to bring science alive in the classroom. Please inquire about our workshops and group seminars for professional teacher training. Our professional sales staff is ready to assist you.
