Introduction of this project 14/1/2014, we were given a task to find out about the temperature of places in our school. There is a total of 7 locations. A 2 day long project. Given a device that costs $100 so we must handle it with care. The seven locations are:

Top floor of Multistorey carpark

Garden outside printing centre

Open space between canteen and block C

Terraces

Field

Running tracks

Fountain area outside General office

Hypothesis Our hypothesis is that places that are concrete surfaced will have a higher temperature than places that are not concrete surfaced as concrete absorb heat easily compare to the other locations.

The data collected is different from the finding of class 2o4. The reason is because it was done at different time so there will be changes in temperature. There are no surprising discovery But we can conclude that places with plants are cooler than places that does not.

Revisiting hypothesis Our hypothesis is that places that are concrete surfaced will have a higher temperature than places that are not concrete surfaced as concrete absorb heat easily compare to the other locations.

It was rejected as places that are not concrete surfaced turn out to have a higher temperature than places that are. The field which is not concrete surfaced have an average of 29.75C but the terraces which is concrete surfaced have an average temperature of 29.20C. Due to the fact that there are a lot of trees around the school, there will be a lot of shade. So we cannot confirm that places with concrete surface will have a higher temperatures as there are always other factors that are affecting it.

Understanding This project allowed us to understand the topic much better as we learned how little factors can make a big change. This project make the topic easier to understand compared to just using textbook knowledge as the project is interesting, fun and engaging.

Thank you!
