The Variation And Evolution Fossil Kit (Product Code: SLE/ES/08) introduces students to intraspecific and interspecific variation using real measurement data. Fifty fossil brachiopods are imbedded in reproduction plastic rocks, and learners use calipers and rulers to record their internal and external dimensions, then compare the numbers within and between species. With reproduction rock formations and a Teacher's Guide included, it works as a biology experiment kit for students studying evolution, and is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Students divide the brachiopods between groups, measure agreed dimensions such as shell length and width with the calipers, and enter the results in a shared class table. Plotting the values as a histogram shows that even individuals of one species are not identical (intraspecific variation), while comparing the spread of two species shows how distinct forms differ (interspecific variation). The discussion then turns naturally to natural selection: which variations might have mattered to a brachiopod living on the sea floor, and how would they be preserved in the fossil record?
The kit sits comfortably among school biology lab equipment in India for evolution and statistics-in-science units, and it also reinforces good measuring technique. Remind students to zero the calipers before each reading, measure every specimen twice, and handle the plastic rocks without twisting so the fossils stay firmly seated.
This kit is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab and serves biology, geography and earth science departments with teaching resources. The company profile gives an overview of the business.
Useful for expanding or extending the measurement activity:
More fossil kits and collections are in the Earth Science category.
How many specimens does the kit contain?
Fifty fossil brachiopods, imbedded in reproduction plastic rocks.
Are the rocks real?
No. The rocks and rock formations are reproductions; the brachiopods set into them are fossils.
What is the difference between intraspecific and interspecific variation?
Intraspecific variation is the difference between individuals of the same species; interspecific variation is the difference between separate species. The kit lets students measure both.
How many calipers and rulers are included?
Calipers and rulers are included, but quantities are not in our current product notes. Contact us to confirm before planning group sizes.
Is there a teacher resource?
Yes, a Teacher's Guide is supplied with the kit.
What does a school need to send for a quotation?
The product code SLE/ES/08, number of kits, delivery address and any tender reference.
Is export supply available?
Yes. We supply schools, colleges and distributors in India and international markets.
