Show how the temperature loss between an adult, a toddler and a baby compare

Extracts from this document...

Introduction

Biology coursework This experiment is set to show how the temperature loss between an adult, year 7 a toddler and a baby compare, we will use beakers of various sizes to represent the above. Apparatus: 1-100ml beaker 1-250ml beaker 1-400ml beaker 1-1000ml beaker Kettle Thermometer Stop clock Method To carry out this test we will first boil the kettle and fill the 100ml beaker 3/4 full, we will then wait till the water reaches 80?degrees before starting the stop clock, after which the temperature will be taken at 2 minute intervals for 10 minutes. This procedure will be carried out for each beaker recording our results in a results table. To keep this test fair we will use the same proportions of water in each beaker (3/4 of beaker full) ...read more.

Conclusion

In my original prediction i said how i thought the beaker with the smallest volume would cool quickest and I am pleased to say from looking at my graph it seems to be right. Evaluation Due to the time limitation we were unable to complete all 3 re-tests which may or may not of effected our results, if time permitted us to we would further this test carrying out the re-tests planned. Also if i was to repeat this test i would use a wider range of beakers to get a more accurate view of the rate of heat loss between sizes. Also due to the lack of computer equipment the tests have to be carried out by us ourselves this means that there is a certain amount of inaccuracy either through inaccurate reading of the thermometer or through human error with stop clocks. ?? ?? ?? ??

    Chlorophyll-fluorescence measurements show that photosystem recovery after re-hydration is rapid9.The recovery of respiration after prolonged desiccation similarly shows recovery in mosses5. It has been suggested that recovery after desiccation involves the reestablishment of membrane integrity and photosystems10. At the scale of a moss gametophyte colony, surface tension is determines the distribution of water around the vegetative tissue5.

    This is because magnesium is more important to plants than iron but less important than nitrogen to plants. Magnesium is one of the raw materials of chlorophyll, and also helps to activate some enzymes involved in energy transfers. Therefore, I predict that in the lemna lacking in magnesium we will see yellow patches on the leaves.
