Heat+Activity+for+P4+Ex+Group+3


 * 1) Hi everybody from P4 Excellent Group 3! We can discuss the questions for Heat Activity 4 here.

Members: Ming Yang, Wei Li, Cody and Faith toc I hope you enjoy yourselves here!

Your sincerely, Ming Yang

(Everybody, please be more active in discussing!) Ming Yang, who is supposed to do the worksheet? 1 person or everybody? ~Faith C'mon, of course everybody, Faith. ~Ming Yang Are you sure? I think it is group work and 1 person will print. Can you give some comments?~Weili But I've already done the whole worksheet! ~MY Me too! T.T ,I did it when Ming Yang said must! ~Faith

This is a good website. [|Sources used in the past, present and future] ~ Ming Yang

Hey Ming yang! How did people find sources used in the future??? They can only pridict :) (At least this is what I think!) Here is another website on oil (a source of heat used in the past- actually present too) [|Oil source] ~ Ming Yang

This is an excellent website. [|Tracing the Energy of the Sources] ~ Ming Yang

Ming Yang, do not post everything! here: [] ~cody

hello! ME AGAIN! [] ~cody

__Helpdesk__
Everybody, post your queries here.

1. 2. 3.

__﻿Questions__
Is solar energy considered a source of energy used in the present? ~ Ming Yang What are the sources of heat energy used in the period between 1940 & 1960? I can't get the answer! T.T ~Faith For the Research and list the sources of heat energy used in the period between 1940 and 1960 with the sources rf heat energy around the home today question, need to add pictures? Also for the table, on the left side, for example have Liquefied petroleum gas, on the right side, need to put sth similar like burning wood, or can like just anyhow put like Kerosene???~Weili

__Answers to Questions Above__
Ming Yang's Question: I am not sure but I think it is and I just put in the present day column.~Weili Faith's Question: Faith, it is at the information there. (PLEASE look down) ~ Ming Yang I still can't find it! can you please make it stand out?!~Faith Wei Li's Question: I did add pictures. I think you can just put them randomly. ~MY

__Information__
Here are some of the informations on sources of heat.

1. Burning wood and coal are sources of energy used in the past. ~ Ming Yang 2. Crude oil is a smelly, yellow-to-black liquid and is usually found in underground areas called reservoirs. Scientists and engineers explore a chosen area by studying rock samples from the earth. Measurements are taken, and, if the site seems promising, drilling begins. Above the hole, a structure called a 'derrick' is built to house the tools and pipes going into the well. When finished, the drilled well will bring a steady flow of oil to the surface. (Explanation of crude oil)~Weili Sources uesd in the present: Solar energy, LPG, Nuclear Power Sources used in the past: Kerosene, Coal and Burning Wood

__﻿Tracing the Energy__
plants that lived millions years ago > a layer of dead plants covered by water and dirt > heat and pressure > coal

Explanation: The plants that lived millions years ago become a layer of dead plants covered by water and dirt. The heat and pressure of the top layers (the water and dirt) helps the plant remains and turned into coal. How did you do the tracing part??????? I mean the second one????~Me

__﻿Difference between the sources used presently and the sources used in the past__
The energy sources used presently are renewable and the amount of energy given out is greater.
