'Run-off'+Group


 * === Important Points about Run-Off: ===
 * === Run-off is the rain that is neither absorbed by the ground nor evaporated. ===
 * === Run-off can carry with it all the loose materials in the catchment, washing soil,fertilisers and pesticides into the waterways. ===

Run-off task card By ALEENA, AURORA and MADDY: = **What is Run-off?** =

**ANS: It is something to do with the water cycle and it is when water goes through drains to reach seas, lakes or rivers. The run-off is the last piece of the Water Cycle.**
= **What is water quality?** = == **ANS: It is how much you use and how good or bad it is. Water is used for drinking, farming, fish production,swimming and much more and most importantly we don't use the same water when we drink or farm. We use water in lots of ways and we use it for different reasons. When we drink water, the water that we are drinking must be good and that is what water quality is about, it is to keep the water safe and fresh for us to drink.** == = Things that humans do to make use of the land: =
 * 1) == **Build buildings.** ==
 * 2) == **Build houses** ==
 * 3) == **Build apartments** ==
 * 4) == **Grow plants - trees, flowers and much more** ==
 * 5) == **Grow vegetables and fruits** ==
 * 6) == **Grow crops and pastures** ==
 * 7) == **Create roads** ==
 * 8) == **Mine.** ==

= **When it rains, where does the water go?** =

**ANS: It repeats the method and it is doing what the water cycle does which means that it goes back to seas, rivers etc.It also goes back to the ocean,pond,stream and lake.**
= **Pictures:** = == **ANS: The first picture has a drain in the middle of the road and it certainly has something to do with run-off because when it rains, most of the water goes through that way on the way to rivers, seas, lakes and oceans. In the second picture, it has nothing to do with run-off because the picture is taken place on a farm and there is no sign of drains and even if there is drains, the water that flows in that farm is dirty and contaminated because the ground is covered in dirt.** == = What impact have we made in our environment or near a catchment area and how could we minimize the effect that has been made by us? = == ** Ans: We effect the environment or a place near the catchment area by littering and blocking the drains and in lots of other ways. We still could minimize this problem by not littering and not throwing stuff like rocks in drains. We could also help minimize this problem by being a good role model because the kids who watch you can also learn that you should not throw stuff and they could learn about th e disadvantages too. ** == = **Internet Research:** =

**ANS: There are a lot of problems about excessive run-off and some of the problems are:**
= Ways we can minimize run-off: = = **Activity:** = =**For the activity, we devised an experiment and this was the results we got:**= = ** What do the headlines say?- Chosen topic: Residents ask '' What's in the water? ' '** = = **ANS:** **Many people asks this same question but, is it just for fun?** = = **People are not saying it for fun, they are saying it because they have no idea of what is in the water and most of them have doubts of whether they are drinking water that is contaminated.** = = **Scientists have researched the water that the people have been drinking and many of them replied that the water is not contaminated but people are still unsure. Many people have found solutions to this problem. Most of them agreed that they should stop littering to save the water they have been drinking but few of them didn't do anything to this matter.** = = **Are people still unsure of the water they have been drinking?** = = **There were no complaints after the solution that the majority chose. Most of the people that were unsure before, now say that they have no doubts at all.** = = **Pollution in our streets:** = = Here is a picture of run-off: = = Here is the picture of the sewage system: = = Sharing information: = = ANS: We found a lot of things that we didn't know through this activity. We didn't know what run-off was and what it's about and also its advantages and its disadvantages. We learnt a lot. =
 * == **The germs that are in the water spreads quickly.For example, the dirt that water takes along with it makes us sick and that water is going through drains to get to rivers and when it does, the river is contaminated and then the river flows all the way until it reaches the lakes and the lake is also contaminated now. It spreads and spreads and when someone drinks that water, he or she will be sick.** ==
 * == **High flows of water can cause flooding and erosion.** ==
 * == ** When a building is built, the way that the water goes is also change d and also less water seeps into soil and that is how run-offs increases. ** ==
 * 1) == The easiest way to minimize run-off is to plan before you take actions. ==
 * 2) == Another thing that you could do is to imagine that you are a raindrop and think to yourself about which way you would prefer[a fun way]. ==
 * 3) == You could seek a scientist's help. ==
 * 4) == If you are a scientist, you could do some experiments and tests. ==
 * =**When the rain was light, nothing really happens to the soil.**=
 * =**When soil and heavy rain are mixed together, they form a muddy ground/pathway.**=
 * =**Sometimes if there is only little soil, there will be more water than the soil.**=
 * =**This experiment depends on the quantity. How much soil and water there is.**=
 * 1) = **There is a big difference between stormwater and the sewage system. Stormwater is the rainwater that flows into the stormwater system and the system includes drains, road gutters and much more. The system does not remove pollutants which is one of the disadvantage.** =
 * 2) =**The systems that the humans built did definitely change the way the water goes through the natural environment. The proof is the water that we are drinking-a water that is not contaminated.**=
 * 3) =The main problem is things to do with stormwater. Stormwater is a problem because it carries pollutants through road gutters and drains to the ocean.=
 * 4) =Run-off may carry pesticides and fertilisers[pollutants from rural areas]. Agricultural and forest practises may affect run-off.=
 * 1) = We learnt a lot of things about run-off. =
 * 2) = We learnt about run-off and that it is part of the water cycle. =
 * 3) = About its advantages =
 * 4) = About its disadvantages =
 * 5) = We also learnt an interesting point. When water bugs are in streams it indicates that it is a healthy stream. =
 * 6) =We learnt about the sewage system - what it is and different kinds of stuff.=
 * 7) =We learnt about stormwater - what it is and its functions.=
 * 8) =To learn some things about run-off, we looked at the water cycle and we now know about the water cycle.=
