living with the lab 2011 David Hall the worlds oceans contain an average of about 35 salt by weight 35 grams of salt for every kilogram of seawater Image credit NASAGSFCJPLCaltech. 5.5C . Demonstrate . that some mixtures maintain physical properties of their ingredients such as iron filings and sand.. . STAAR 2013 #21; RC1; Supporting. 1. A mixture of beads was placed in a container, as shown below. The beads are of various sizes and each one is made of plastic, glass, or steel.. Investigation 1. Let’s talk about our results. Which. mixtures were separated by the screen?. Gravel. Which mixtures were separated by the filter?. . Powder. How are the screen and filter similar?. Investigation 1. Separating Mixtures. Part 1 – Making & Separating Mixtures. Vocabulary. Mixture. – a substance containing two or more materials with different properties.. Property. – a characteristic of an object (something you can observe). 10-8-14. . Sorting. Separating mixtures with your hands.. Ex: separating pop corn kernels, black beans, & rice. 2. . . Using a Magnet. Using the magnetic property of a substance to separate a mixture. Mixtures and Solutions. Investigation 1. Part 1. Making and Separating Mixtures. What is a mixture?. What is a solution?. What is the difference b/t a mixture and solution?. Our first investigation is figuring out what a mixture is and what a solution is…. Showdown. Name . the two parts of a solution. Solute (solid) and solvent (liquid). In the salt layering lab, the yellow salt solution floated on top of the blue solution because the blue solution was ________ than the yellow solution.. 4.1 Chapter Review. 1. List . two examples each of a solute, a solvent . and a . solution.. solute—an . example such as salt, sugar . solvent—an . example such as water, kerosene . solution—an . Classifying Matter by Composition. Homogeneous. – . matter with a uniform composition. Heterogeneous. - . matter without a uniform composition. Substance. - A pure type of matter that does not vary from sample to sample. Includes . Mixtures. A combination of two or more substances that do not combine chemically, but remain the same individual substances; can be separated by physical means. Two types:. Heterogeneous. Homogeneous. Chapter 5. Ex:. Melting. Freezing. Boiling/evaporation. Condensation. Sublimation. Dissolving. Bending. Crushing. Breaking. Chopping. Filtration. distillation. Physical change. Does not make a different substance. Boiling . Burning. On a molecular level, how would you describe the difference between boiling something, and burning something?. Bellwork: Monday 4/23/2012. Physical Change. Chemical Change. Different Phase- Still same bonds; farther apart, moving faster. . Sorting. Separating mixtures with your hands.. Ex: separating pop corn kernels, black beans, & rice. 2. . . Chromatography. Separating colored mixtures.. Ex: Black marker. 3. . . Using a Magnet. (35 grams of salt for every kilogram of seawater).
