﻿Hi everybody, this is Mrs. Patterson, welcome to Lesson Three. How can we use climate graphs to compare rainforests and deserts? Today, we're going to be looking at part of this as the Unit One ecosystems. We are going to be looking at climate graphs, we are going to be looking at what they are, how to use them, and then we're going to be applying these and our mathematical and graph skills in order to answer some really important questions. You are definitely going to need a pencil, a pen, and something to write on. Please go and get those now, and I will see you in a couple of minutes. Okay, so, firstly then, what is a climate graph? So, a climate graph is what you can see on your screen now. So, a climate graph, it displays the temperature and the precipitation for a particular area over the course of the year. Okay, so let's have a look at how we actually read a climate graph. So, on a climate graph, we have got three axes. We've got an X axis, a Y axis, and a Z axis. So, we can see those here. So, the X axis is the months of the year, that's down the bottom of our climate graph. So, they are represented by the first letter of the month. So, for instance, J at the beginning, it stands for January, and we go all the way through to December. The Y axis is the temperature, and this is portrayed in Celsius. So, we can see that in that pink box there, it goes from 0 all the way up to 20 degrees Celsius, and this is linked to the red line that is on our graph. So, temperature is displayed as a line graph. Then we have our Z axis. Now, the Z axis is over to your far right, and it is measured in millimetres, so it goes from 0 all the way up to 100 millimetres, and this is represented by the blue bars. So, the blue bar chart is the rainfall, the red line is for temperature, and the different bars and the different points in the lines are linked to the months of the year. It is important to remember, when we are looking at this climate graph, that all of this data is based on averages. So, this is the average amount of rainfall per month, and it's the average temperature per month for a particular place. So, that's important to remember, it's the average. So, all of the daily temperatures and the daily rainfall all added together and then divided by however many days there are in the month. So, let's have a look at a task, then. So, using the same climate graph that we've just looked at, I would like you to complete the four questions that are on your screen. So, there's questions 1 to 4, and it's all to do with reading that climate graph. So, remember that your temperature is by the red line and your rainfall is by the blue bars. Pause your video now, and this should probably take you around ten minutes to complete. Excellent, guys! So, let's go through the answers that we've just done for those four questions. So, question number 1: the red line represents temperature measured in degree of Celsius. Number 2: the blue bars represent precipitation measured in millimetres. Question 3: the highest amount of precipitation fell in September and November and was 100 millimetres. The lowest average temperature fell in January and was around 4 degrees Celsius. So, if we have a look at our climate graph, I have identified the areas that are in green boxes for our questions 3 and 4, just to highlight this further to make sure that we are secure in our knowledge about where we are getting our information from. So, the highest amount of precipitation fell in September and November, and was 100 millimetres, and that's highlighted in those two green boxes that are on the September and November blue bar line. Then, we've got the lowest average temperature fell in January and was 4 degrees Celsius, and that is highlighted in the green box that is on the red line in January. If you need to amend your answers, then please have a look at mine. Make sure that you have got the correct answer down, and that you are secure in the knowledge about how to read a climate graph moving forward. Pause the video here if you need to amend any of your answers. Excellent, well done guys, for any amendments that you had to make. So, let's move on to have a look at comparing tropical rainforest climate graphs against deserts. So, have a look at the two different types of climate graphs that we can see. We can already see that there are some very clear differences in terms of rainfall and in terms of temperature. Let's have a little look further at each one individually, and then we're going to answer an exam question comparing both of these climate graphs. So, here, what I would like you to do, using just the tropical rainforest climate graph, is I would like you to answer the question that is one your screen now. So, you need to fill in the gaps. Pause the video now, and this should take you around five minutes to complete. Okay, let's have a look, then, at some answers for this tropical rainforest. So, the hottest month in Penang's tropical rainforest was September, with temperatures of around 27 degrees Celsius. The coldest month was May, with temperatures of around 24 degrees Celsius. The month that received the highest amount of precipitation was March, with 300 millimetres of rainfall, and the driest month was August, with 70 millimetres of rainfall. Have a look at my answers and have a look at yours, make sure that you have got the correct answers, and that you are reading the line graph and the bar graph correctly. So, let's have a look at, then, at the desert climate graph. So, here is our desert climate graph. Exactly the same as you did for tropical rainforest, can you fill in the gaps with the relevant information from the climate graph? And, again, this should take you around five minutes to complete. Pause the video here. Great stuff, guys! Let's have a look, then, at the answers for this hot desert climate graph. So, I have got that the hottest month in the Sahara desert was July, and this was with the temperature of around 34 degrees Celsius. The coldest month was in January, with temperatures of around 13 degrees Celsius. The month that received the highest amount of precipitation was January, with 20 millimetres of rainfall, and the driest month was June, with 0 amount of rainfall, so there was no rainfall at all in the month of June. Have a look at my answers, and have a look at yours. See if you need to amend any to correlate with mine. If so, pause the video here, and we will move on shortly once you're ready. Excellent, guys! Let's do a quick learning review, then, of which statements are true. So, option number 1: deserts have the lowest temperatures in July. Option 2: the Sahara desert's hottest month is July. Option 3: tropical rainforests have consistent temperatures all year round. And option 4: tropical rainforests have the same amount of rainfall each month. Pause your video here and choose which statements out of the four are true. This should take you around two minutes to complete. Welcome back! So, hopefully you found those statements fairly easy to come up with which ones were true. So, let's go through the answers now. So, our first statement that is true is option 2. The Sahara desert's hottest month is July. Excellent, compared to deserts have the lowest temperatures in July, that is a false statement. And then our second statement to be true is option number 3. Tropical rainforests have consistent temperatures all year round. To compare it to they have the same amount of rainfall each month, they don't, and we know that from the bar graph that we saw on our climate graph. Excellent stuff. So, make sure that you've got the correct statements written down as a learning review, and then we will move on shortly. So, coming on to the main part of our lesson today, I would like you to compare the two climate graphs. The first one being the tropical rainforest climate graph that you've already seen, and the second one is the hot desert climate graph that, again, you have already seen, and you've both answered questions on. So, in order to compare the two climate graphs, there is some success criteria that you must do. So, one: you need to state a similarity between the temperature and the rainfall of both of the graphs. Two: state a difference in temperature and rainfall against both of those graphs. And, three: calculate a difference. So, for example, I've said in July, the desert is 9 degrees hotter than in the tropical rainforest in July. So, you need to read both of the climate graphs and find similarities and differences, and give me specific data from both of those graphs in order to compare them. This task should probably take you around ten minutes to complete, so pause the video now and return once you have completed. So, this is such a fantastic job, guys, this is such a hard task to do, to compare two climate graphs, and only at the beginning of the lesson you've looked at how to read a climate graph. So, some fantastic job. So, let's have a look at some answers, then, that we could have suggested out of these climate graphs. So, in terms of similarities, you could have said that both tropical rainforests and deserts have two seasons. That is a similarity between them. Tropical rainforests have a wet season, which is between December and April, and deserts have a dry season, which is between May and September. The differences that you could have suggested is, as I've already suggested, in July, the desert is 9 degrees hotter than in the tropical rainforest. However, the tropical rainforest has 53 millimetres more rainfall in July, when compared to the desert. There are a multitude of differences that you could have suggested between any of the months from January through to December, and I can't go through all of them, but this is an example for you. So, have a look at yours and have a look at mine. Do you need to redraft your answer, and do you need to rewind the video, and go back and have a look at those climate graphs again to make sure that you've got the correct data from a particular month that you wanted to focus on? So, pause the video here, and if you do need to make any amendments, this should take you a maximum of five minutes to complete. Well done, guys, for making those amendments. So, that does bring us to the end of our lesson today, where we have looked at how we can use climate graphs to compare rainforests and deserts. We have looked at what a climate graph is. Then, we've looked at how to read a climate graph. And then, we have compared two different climate graphs and answered exam questions on them. Next lesson, we're going to be looking at high and low pressure air pressure systems and how they influence where biomes are located. If you would like to share all of the fantastic work that you have done today, then please ask a parent or a carer to share your work on Instagram, Facebook or Twitter tagging @OakNational and #LearnwithOak. See you next lesson. Bye!
