Noise is sound being a nuisance or causing ear damage but sound proofing against this is difficult. This is because all sorts of materials vibrate and transmit sound. Having sound absorbers, such as carpets and curtains helps to absorb sound. Also ..
Babies and adults are warmer than their surroundings and constantly lose heat to it. Other things being equal, how quickly they lose heat depends on their size and the surrounding temperature. The
Cooling curve Two temperature sensors can collect some interesting information about cooling during a change of state. In this experiment the temperature of a water bath increases as a substance cools. But the unusual...
Heat insulation A temperature sensor can be used to study the insulating properties of different materials. Two temperature sensors allow a simultaneous comparison to be made. In this experiment two beakers of hot water...
Three plastic cups are stacked inside each other and a temperature probe placed between each cup. Before stacking the final cup hot water (take care) is poured into the middle cup. Quickly stack the...
You can use a temperature sensor to study the insulating properties of materials. Two temperature sensors allow you to compare different materials at the same time. In this example two beakers of hot water...
An investigation with insulated and un-insulated beakers – reloaded “I bought a metal mug to carry my coffee for my daily trip to the train station. But twenty minutes down the road, I wasn’t...
Nicola Terry hitches a ride on the Heatseekers vehicle in Cambridge as speaks with Dawn Morley. Dawn explains how their infra red camera is able to see where a house loses its heat. They...
