Welcome to FlashyScience, your very own virtual laboratory
Here you are the scientist, taking control of the selection, collection and analysis of data to bring experiments to life. Our virtual experiments allow you to explore physics and engineering, and refine your scientific skills in an interactive environment.
Tensile Testing (FULL)
Structural materials are required to withstand a variety of applied loads in use. Understanding how these materials respond to applied loads is vital for informed materials selection. Here you can investigate how materials behave under tensile loading (loads applied along the length of a material to cause stretching).
This virtual experiment allows you to investigate Ohm’s law using digital multimeters (DMMs) to measure voltage, electrical current and electrical resistance values generated by a power supply and a resistor. The experiment also allows you to explore the colour codes of resistors and the variability of resistance values in resistors with the same colour code. These investigations will also teach you to use DMMs and practise handling experimental data.
A potential divider is a simple circuit that uses resistors to supply a variable 'potential difference' (i.e. voltage).This can be used for many applications, including control of temperature in a fridge or as audio volume controls. Understanding how the resistors in the circuit allow this is important for designing many electronic circuits. Here you can investigate how changes in the two resistors can lead to different voltages across them.
Gases are complicated. They are full of billions of molecules that are colliding. To describe how all these interactions is impossible, so the concept of an Ideal gas is made to approximate all these collisions and allows us to predict the behaviour of real gases. In this experiment you can find out the temperature, volume and pressure of a gas are all related and how you can create a heat engine.
