Popular Science Appratus Workshops Private Limited

Explore the use of DNA technology in crime solving.
This activity brings the 'real-world' applications of biotechnology to life and will simulate discussion on the ethical considerations associated with the use of cutting-edge technology. 
Contains materials for up to 40 students.
Your students will become forensic scientists as they apply the latest innovations in DNA technology to a scenario-based DNA murder mystery. 
They'll compare the electrophoretic results of DNA samples from a 'crime scene' with those from various suspects. 
Using a simplified DNA fingerprinting procedure, they'll then solve the crime based upon the fragment patterns revealed on the gel. 
In the process they'll learn the basic concepts of DNA fingerprinting as well as insight into why this revolutionary process is so accurate. 
They'll also get a 'hands-on' education on DNA structu

A decimal abacus is a tool used in math labs to help students understand decimal numbers and place value. 
It representing ones, tens, hundreds, etc., as well as decimals.

Calculating instrument that uses beads that slide along a series of wires or rods set in a frame to represent the decimal places.
