During science we have been conducting
experiments on heat.
We tested the
temperature of hot water and found that it began getting cooler and concluded
that heat will always travel from a hot area to a cooler area.
We then
discussed that there are ways to try and keep heat in but that also at times we
would like heat to travel through a material.
This brought us
onto looking at thermal insulators and conductors. We used our knowledge to
predict which material allowed heat to travel through it. We were right! The
answer was the metal spoon therefore it was a conductor.
Then Miss Prest
explained to us a problem. She said that on a morning she is soooooo busy that
her coffee gets cold before she has time to drink it. How could we help????
We planned a
science experiment to test different materials. In our groups we wrapped a container of hot water with the material and then measured the temperature every 5 minutes. We used tinfoil, fabric,
newspaper and bubble wrap and ensured it was a fair test by keeping the water,
containers and time we tested the temperature the same.
We concluded
that fabric is the best thermal insulator!
