In the previous chapter we have all learnt what matter actually is, its different states and its reaction to changes to its immediate surroundings. Now we’ll learn about the PURITY of matter. The water we drink, the air we breathe in, are those all pure matter containing same type of particles? We can answer this question after finishing this chapter. In this chapter we’ll learn: 1. What are pure substances and what are mixtures? 2. What is a solution? 3. What is concentration of a solution? 4. We’ll perform an activity on chromatography. 5. What is a Suspension? 6. What is a Colloid? 7. How to separate components of mixture? 8. How to separate 2 immiscible liquids and the process of distillation? 9. What is an atom? 10. What is the difference b/w physical and chemical changes? 11. What are Metals and Non Metals?

My project is chromatography. Chromatography is the separation of complex mixtures. https://sites.google.com/site/hsea2015marinaanna26/ STEM SOS is a rigorous, interdisciplinary, standards-focused, and engaging STEM teaching approach that is teacher-facilitated, student-centered and directed through sets of project- and inquiry-based (P&IBL) projects. This PBL approach is to maintain the focus on standards-based teaching while enriching and extending the learning of students through PBL projects. The goal is to promote not only collaborative skills and student ownership of learning but also to promote student success in state and national standards. "Harmony Public Schools: Where Excellence is Our Standard" Harmony Schools blend: The highest standards and expectations, A rigorous math and science-centered curriculum, and Engaged and Dedicated teachers and families,... to cultivate excellence and prepare students to succeed in college, careers and life. We are equipping Harmony Schools' students for college, preparing them for life and helping them achieve excellence, while making a positive impact on our community, our state and our nation. At the Harmony Schools, we are dedicated to creating an academically rigorous environment that nurtures students, expects excellence and helps all students realize their full potential. At Harmony, we believe every child can succeed, and we are committed to helping them realize their full potential At Harmony, we believe families play an important role in helping students achieve excellence and are an integral part of our school's community. A Harmony education fosters excellence as a life-skill, and opens the door to a world of opportunity. At the Harmony Schools, by focusing on math and science, we are developing the next generation of innovators and thinkers we need to succeed in the global economy and environment. At the Harmony Schools, we are leading the way in math and science education, so our children can lead our state and our nation in the future. At Harmony, we provide a safe, nurturing academic environment that expects excellence and prepares students for success in college and in life. Harmony Public Schools is the recipient of Race To the Top District (RTT-D) grant in 2012. With RTT-D grant funds, Harmony is implementing a cross-disciplinary, multi-sensory, technology-enabled project-based learning (PBL) curriculum that integrates STEM, social studies, and English Language Arts (ELA). Researchers have documented numerous benefits of project-based approaches beyond the development of content knowledge: students learning through a project-based curriculum develop the ability to transfer their learning to new situations, demonstrate an increased ability to define problems and support their reasoning, and are better able to tackle conceptual problems than those taught with a more traditional curriculum. Through creative and innovative uses of technology such as video storytelling and web sites, Harmony students are publicly sharing their work both throughout the process and in a culminating capstone presentation, ensuring an authentic and meaningful context for deep student learning. Harmony Public Schools have developed a STEM curriculum that incorporates project-based and inquiry-based learning titled “STEM Students on the Stage (S.O.S TM)” with the Race to the Top grant funded by U.S. Department of Education with the goal of not only increasing students’ STEM knowledge and interest but also balancing student-centered teaching with state and national standards to promote success and investment in the learning process through PBL projects

I created this video with the YouTube Video Editor (http://www.youtube.com/editor) I added some awesome music to it, to make it better. !!!Chlorophyll Chromatography!!! (Why Do The Leaves Change Color - Chromotagraphy Paper Experiment) SCIENCE EXPERIMENT Crazy Chris is checking out the fall leaves and shows you how to see color in a green leaf with a chlorophyll cinematography test you can do right at home! Objective: To understand leaf colors pigmintation and why the leaves change color in the fall. Materials Needed: ~ Maple Tree Leaves ~ Coffee Filter ~ Scissors ~ Glass Jar ~ Rubbing Alcohol Step 1) Start by getting yourself some maple leafs oak leafs or any other leafs. Step 2) Cut a coffee filter into a 2.5cm wide strip and using a coin scrape the leaf in a straight line alone the coffee filter. Step 3) Pour a small amount of rubbing alcohol into a container and then place your coffee filter strip so that it just dips into the rubbing alcohol. Let this Sit for for 2-4 hours. HOW DOES IT WORK: The reason tree leaves change color in the fall is because trees sence the decreased amount of light, colder tempretures and the lack of rain water. When these things are senced the tree releases chemicals that shut off water an food delivery to the leaves and they begin to shut down. As leaves shut down they stop making cholorphyl and the and green coloring starts to fade away and the leafs true color can then be seen. Which is why you get two colors on your coffee filter, the alcohol seperates the chemicals in the chloraphyl. Eventurally the leaf turns brown due to cell wall death and fall off the tree. The color in the leaf depend on chemicals either disolved or as floating granuals in the leaf cells cytoplasum. Leaves that are yellow have the chemical xanthaphyl, orange leaves have the chemical charetene, red leaves the the chemical anthocyanin and some golden brown leaves have the chemical tanans in them. Xanthaphyll and caretenes stay in the leaf through out the leafs life but anthysayinins which is caused by sugar build up in the leaf and tanans develpe towards the end of the leafs life. Trees evovled color changing leaves as well as shedding leaves for two major reasons, first is to stop inscects from snacking on the leaves while the tree reabsorbs the nutrients by scaring the insects off with colors as well as to stop them from snacking on the leaves through the winter. Colors also help trees reabsorb nutrients more effeciently and also drop thier leaves cause its just to much work to care for leaves over the long cold dry winter months. !!!Chlorophyll Chromatography!!!

Science Force is a hands-on program designed to parallel the elementary grades K-5 science curriculum. This short video is designed to train parents and teachers who will be leading the lab for a 45-minute class visit as students engage in activities that will help them better understand mixtures and how a process of chromatography can be used to divide mixtures. A mock crime has been committed. Someone has stolen the principal's lunch right out of the staff refrigerator, leaving a note written in a black marker. Using chromatography, the students take a sample of the note and then determine which brand of marker made the note. They create a reference from each suspect's brand of marker to determine who may have been the culprit! In doing so, they find that not all brands of black markers have the same ink recipe, and they use chromatography to divide the components for further analysis. For a copy of the written text and lab sheet supporting this lab, please go to http://science-force.com and learn how you can bring this program to your school. The ideas are free, but realize that these labs are designed by volunteer parents, so the accuracy of the content and the safety when performing this lab rests upon you as the implementer, and not the Science Force program or any persons who are associated with this program.

A pretty simple experiment to start off folks! But fun and kids love to watch this one... Try it out! ~ CHROMATOGRAPHY ~ Aim - To separate a mixture of chemicals in a liquid to see what they are made of! Materials - Paper towel Water tray Water Textas / pens / pencils / other solutions (use your imagination guys!) Jars / bottles Sticky tape Method - 1. Draw a large dot on the paper towel (approx 2 - 3 cm in diameter) for each colour or type of pen. 2. Using the sticky tape, tape the paper towel to the jars so that it stand upright. 3. Place this in the water tray 4. Add water and the experiment will begin! 5. Leave for 10 - 15 minutes and see what chemicals will separate from the solution. Discussion - in chromatography, the water will travel up the page via capillary action, where water travels upwards agaunst the force of gravity. Plants will transport water this way. In our video, the pigments will separate from each of the texta colours. The lighter pigments (yellow, blue) will be carried by the speed of water and travel faster. Heavier pigments (pink, black) will travel slower and separate from their lighter friends. This allows us to see what pigments each colour ink is made up of! Who knew Blue textas had pink in them? At Home - You can try many different ideas when drawing. Your children could draw a picture or compare different drawing tools, such as pens, pencils, crayons, etc. There are so many things that you can test using this method. You don't need to be limited to drawing on the page... Its amazing what household chemicals can be separated and the interesting results that they give. This one's about encouraging your child to be a scientist and using their ideas. Have fun with it! Encourage your children to explore their own ideas! Please post any results that you get or questions / comments. Go Science!

Basically this is a chromatography experiment to show whether if a different dye from a different candy like M&M and Skittles but of same colour affects the reaction in the chromatography paper. There are 4 different colours use to have a fair experiment and we get the dyes by placing the candies on water where the colours gets mixed with water and then we use those dyes and put some dots on the chromatography paper and then put the chromatography paper in a container to perform the experiment. Therefore this video will show you whether there is difference between using different candies of same colour.

Living and Nonliving Things. Things which can grow, move, breathe and reproduce are called living things. Living things can also feel emotions like anger, fear and happiness. After growing and living for a long time living things ultimately die. Examples of living things are human beings, animals and plants. Plants cannot move from one place to another. However, plants move their stem to face the sun. Hence, they are also living things. Things which cannot grow, move, breathe and reproduce are called nonliving things. They do not have any kind of life in them. Examples of nonliving things are rocks, bucket and water.

In this experimental set up 3 potatoes - 2 raw and 1 cooked are used. All 3 have a cavity and are placed in a tray of water. One of the raw potatoes and the cooked one have salt filled in their cavities. The cavity in the other raw potato is left empty. When the potatoes are observed some time later, the salt in the raw potato is dissolved in water, while the salt in the cooked potato is still in the solid form with no water. The 3rd potato is without water. What happened here is like this. Because of osmosis, the cells of the potato surrounding the salt filled cavity gave out water into the cavity. This water is drawn from the water lying in the tray. The cooked potato cells are dead and so do not undergo osmosis. So no water is drawn in and the salt remains dry. In the case of the 3rd potato, as there is no salt, the cells do not develop sufficient osmotic pressure to draw in water..

Here we learn how to prove that the leaves of plants contain starch, which is created as a result of photosynthesis? Remove a plant leaf and heat it in an alcohol bath as shown in the video. The alcohol removes the chlorophyll that makes the leaves green and the heat softens the leaf's cell walls making chemical reactions easier to do . Dip this leaf into a dilute solution of iodine and watch the leaf turn dark green as a result of starch and iodine combining to form a violet coloured complex. Thus, we see that leaves contain starch.
