African American Scientist Series
Dr Henry Cecil McBay
Sealed Bag Reaction Chemistry Classroom Kit
Dr Henry Cecil McBay worked his way up from humble Texas beginnings to Chemistry research and teaching. Throughout his long career he inspired students and won many awards and honors in the field of Chemisty. One of his favorite demonstrations combined 2 materials to make a new substance with properties totally different from the originals. This facination with chemistry is the theme of this "Reaction In a Sealed Bag" demonstration.
This is a great experiment to show chemical change. Evidence of a chemical reaction include: color changes, heat being lost, heat being absorbed,and the formation of a gas. All of these can be observed in this one experiment, an example of chemical changes.

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.
