Water+Study

= We are starting to learn about Water Conservation. You will do a project to teach about saving water. You must include 5 facts about ways to save water, or what happens when water is wasted. = = These must be "new to you" facts that you learned from Internet research, or from filling out your Water Use Worksheet at home. =

This semester we studied water **__Today you will learn more about pH, and you will write a How-To guide for testing the pH in your system. In your notebook, you will need to explain step by step for testing pH, and explain why a hydroponic farmer needs to test the pH.__** **__Read about pH here and read about pH for plants in a hydroponic system here__** **__Look at the chart below and you will see that most of the nutrients are available at a range of 6.0-6.5__** 

Students investigated the properties of water in containers, as well as water droplets Students examined how water flows through various Earth materials Students designed experiments to the factors that affect the rate of evaporation

Evaporation Results Now that you have completed three experiments to study the factors that affect the rate of evaporation, you need to share your results with the world (or at least with the school:) Choices: 1) You may design a comic strip that teaches about how surface area, temperature, and covering a container all affect evaporation 2) You may create a play or puppet show that teaches about how surface area, temperature, and covering a container all affect evaporation 3) You may draw a poster or children's book that teaches about how surface area, temperature, and covering a container all affect evaporation 4) You may compose a rap song that teaches about how surface area, temperature, and covering a container all affect evaporation 5) You may write a response to this prompt: " A hydroponic farmer is worried that the water from the reservoirs will evaporate too quickly. What recommendations can you offer the farmer, with your expert advice on how surface area, temperature, and covering a container all affect evaporation?"

Please note that however you choose to share your knowledge, you MUST explain how temperature, surface area and a covering affects the speed at which water evaporates. Please respond back with a comment to explain who (if anyone!) you are working with, and what you plan to do for a project) Questions? See me.

We are studying all about the water cycle Evaporation= the liquid water is warmed by the sun and turns to water vapor in the air Condensation= the water vapor gets cooled when it travels high up, and it turns back into liquid water. It hangs out in a cloud until there are enough other water droplets Precipitation=the water falls back to Earth in the form of rain, snow, sleet, or hail. The form depends on the temperature of the surrounding air Runoff=the water falls directly into a body of water, or it flows across a surface and into a body of water such as a river, pond, ocean, stream, lake,Groundwater= the water seeps into the ground, where it travels through a variety of earth materials as it travels down.

 * We are learning about the water cycle, which is how water moves from liquid to gas, to liquid again. Did you know that we have the same water now as in the time of the dinosaurs? It keeps changing where it is located, thanks to the water cycle!**


 * This week you are working to teach us what you know about the water cycle. The only thing you HAVE to include, is an explanation of evaporation, condensation, precipitation, and collection (runoff or groundwater)**
 * Other than that, the sky's the limit! So, you could research a particular weather related natural disaster, create a rap song, make a poster, develop a play or puppet show, etc.**

 * Now let's set up a quick experiment. Take a clear jar with a lid, a plant, and 100 ml of nutrient water. Place the plant and the water inside, tighten the lid, and leave the jar in a sunny spot.**
 * The next time you come to the greenhouse you will need to draw what you see. Are there droplets on the container? Why? Draw and explain in your notebook.**

 * Earlier you drew a system in your notebook. You sketched exactly how the water gets from a raindrop to your plants. Each time you come you will also need to test the pH and the EC. Make a chart in your notebook to write the info down, but also include it here by clicking "edit", recording your info, and then hitting "save"**

How does water get to the plants in your system?
 * partner names || pH and name of system || EC and name of system || date and notes ||


 * Directions:**
 * Today you will start an evaporation experiment with your Water partner.**
 * 1)** **You will measure out 35 ml of water and pour it into a vial and cap it. Repeat with another vial.**
 * 2) Weigh the water in the vials using a balance scale and gram weights. Record the weights.**
 * 3) Measure the height in inches of the amount of water in the vials. Record the heights.**
 * 4) Place one vial in the refrigerator and take the top off. Place the other vial in a warm place in the greenhouse and take the top off.**
 * Make sure to measure the pH and the EC of the system you sketched. With remaining time you may start to draw a final copy of your system you sketched,**
 * Last time you explained What is Surface Tension?**
 * You also read "Which Way Does It Go?" on page 4 in the __Water__ book. Then in your regular science notebook, you wrote a response to the "Water Observations" on page 10 in your water science notebook.**


 * Directions: Today you will draw how the water gets to your plants (make sure you include all the pipes and the water reservoir). You will test the pH and the EC, and you will record it on our greenhouse log**
