Sometimes, extenuating factors can affect the overall outcome of the desired model projection, so while the models we work with may approximate towards an ideal outcome, the actual outcome is prone to some deviance from the model. You might notice the similarities this has with calculus - And you would be right. One could say that both Isaac Newton an

[P4 Science - Heat] The presenter Steve Mould covers a joke he did for a live show called Festival of the Spoken Nerd. (I have the DVD sets. Don't ask why, please) Gah, of course, the Canadians!

[S1 Science - Density] The following claim was made the other day, where peeled oranges sink but whole oranges float. Maths presenter Matt Parker walks with you through the scientific process of determining the density of the orange and its individual parts. You could stand to learn a lot from his methods, that is indeed an accurate way of measuring the mass and volume of an orange. (Make sure to zero out the weight of the paper tower as well, for maximum accuracy! Not all pa
