Robertson, Bill – Science and Children, 2016
Since nearly every science curriculum in the country contains a section on living and non-living things, Bill Robertson believes that pretty much anyone who has taught the subject has run into difficulties. It seems as if no matter what criteria you use to distinguish between the two you can nearly always find exceptions. This article provides a…

Robertson, Bill – Science and Children, 2014
At first glance it seems easy to attribute cause and effect when it's not applicable, either through mistakenly taking every correlation as a cause and effect relationship, misinterpreting the meaning of independent and dependent variables, or not focusing on direct causes. Sometimes it's easy to help students understand where…

Robertson, Bill – Science and Children, 2013
Contrary to popular opinion, electron microscopes are not used to look at electrons. They are used to look for structure in things that are too small to observe with an optical microscope, or to obtain images that are magnified much more than is obtainable with an optical microscope. To understand how electron microscopes work, it will help to go…
