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?

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.

We are using a scientific method called chromatography to see what colours have been used by different manufacturers to make their black markers. Surprisingly black colour hides a bunch of bright colours. To take the experiment a bit further, we used permanent market too, but it does not dissolve in water. This gave a topic for discussion with Max about what kind of markers we would use in deferent situations. If we want to be able to wash it easily with water afterwards or we want drawing to stay even if we take it outside and it rains. ===================================================== ➜ TheDadLab on Facebook: https://www.facebook.com/thedadlab/ ➜ TheDadLab on Instagram: https://www.instagram.com/thedadlab/ ➜ TheDadLab on Twitter: https://twitter.com/thedadlab ➜ TheDadLab on Pinterest: https://pinterest.com/thedadlab/ ➜ Website: https://thedadlab.net/ ===================================================== Please subscribe to see more upcoming videos http://bit.ly/ThedadlabOnYoutube My main topics include: unique, creative, educational toys for kids, kids science experiments, fun educational activities, must have products for children, kids fashion, dad’s lifestyle, children friendly places to go.

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.

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!

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

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.

Indy Labs - We Put The Science In Your Hands In this episode, we explore how ink colors are actually put together...by taking them apart! Chromatography is a way to separate color mixtures into their individual, visible parts, and we'll show you an easy, "at home" way to do it. Once we've got the concept down, we'll also apply it to making some fantastic summertime (or anytime) butterfly decorations! The Indy Labs series focuses on at home science experiments that are low cost and (usually) easy to do, but still drive the science concepts home. Some science videos show you how to do something cool, but explain very little of it. Others explain concepts, but are very passive and give the viewer little to actually do. With Indy Labs, we put the science in your hands, teaching you concepts, but at the same time, giving you an experiment to try on your own! If you try the lab, please leave a comment and let us know how it went. Also, snap some photos of YOUR at home trials for this or any of the Indy Labs experiments, and upload them to Twitter and/or Instagram. Use #IndyLabs so we can all see your results!

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..

Introduction to Fractions. Fractions express a part of a whole. Fractions can be written using two whole numbers and a line. Number above the line is called numerator. Number below the line is called denominator. Denominator tells us total number of parts in a whole. Numerator tells us how many parts are taken from the whole. Note that, denominator cannot be zero because we cannot make zero parts of a whole.

In this video, we look at one of the Chemistry required practicals. This is making a soluble salt. We look at the stages involved and discuss some of the key points about this practical. It's highly likely that you will get a question on this in your GCSE exam, so it's important that you learn the stages.
