Pasco Adjustable focal length lens

 Demonstrating the @pascoscientific adjustable focal length lens to show how the lens in the eye works. One of the best bits of kit I have used.

Salt structure

 Taking some of the atoms away from the models allows the students to better visualise the crystalline structure and see into the molecule.

A level Maths

Teaching is not just about teaching students about Maths but how to go about solving problems and sometimes by their very nature a new problem has to be explored to work out how to solve them. Learning strategies to solving problems is much more important.

Fractional distillation

Looking at crude oil and extracting the different fractions. The first fractions burnt well but subsequent fractions were impossible to light which surprised the students.

Wireless Smartcart with the Vector Display

Using the @Pasco smartcart with the Vector display is a good introduction to what is going on. Immediately the  vector quantity can be seen on a qualitative experiment before burrowing down into the actual numbers and working out the equations.

DNA

Taking a close look at DNA. The backbone and the way it is shaped related to how it functions. Then looking and modelling some histones to block the gene sites.
 

The ENG Button

 "I can't change into scientific notation", say the students then they meet the ENG function on the calculator that they have never noticed before.
