This PowerPoint is one small part of the Matter, Energy, and the Environment Unit from www.sciencepowerpoint.com. This unit consists of a five part 3,500+ slide PowerPoint roadmap, 12 page bundled homework package, modified homework, detailed answer keys, 20 pages of unit notes for students who may require assistance, follow along worksheets, and many review games. The homework and lesson notes chronologically follow the PowerPoint slideshow. The answer keys and unit notes are great for support professionals. The activities and discussion questions in the slideshow are meaningful. The PowerPoint includes built-in instructions, visuals, and review questions. Also included are critical class notes (color coded red), project ideas, video links, and review games. This unit also includes four PowerPoint review games (110+ slides each with Answers), 38+ video links, lab handouts, activity sheets, rubrics, materials list, templates, guides, and much more. Also included is a 190 slide first day of school PowerPoint presentation.
Areas of Focus: Matter, Dark Matter, Elements and Compounds, States of Matter, Solids, Liquids, Gases, Plasma, Law Conservation of Matter, Physical Change, Chemical Change, Gas Laws, Charles Law, Avogadro's Law, Ideal Gas Law, Pascal's Law, Archimedes Principle, Buoyancy, Seven Forms of Energy, Nuclear Energy, Electromagnet Spectrum, Waves / Wavelengths, Light (Visible Light), Refraction, Diffraction, Lens, Convex / Concave, Radiation, Electricity, Lightning, Static Electricity, Magnetism, Coulomb's Law, Conductors, Insulators, Semi-conductors, AC and DC current, Amps, Watts, Resistance, Magnetism, Faraday's Law, Compass, Relativity, Einstein, and E=MC2, Energy, First Law of Thermodynamics, Second Law of Thermodynamics-Third Law of Thermodynamics, Industrial Processes, Environmental Studies, The 4 R's, Sustainability, Human Population Growth, Carrying Capacity, Green Design, Renewable Forms of Energy (The 11th Hour)

This unit aligns with the Next Generation Science Standards and with Common Core Standards for ELA and Literacy for Science and Technical Subjects. See preview for more information
If you have any questions please feel free to contact me. Thanks again and best wishes. Sincerely, Ryan Murphy M.Ed www.sciencepowerpoint@gmail.com

The Styrofoam cup didn't dissolve with the water because, they have different properties, the water is polar, and the cup is non-polar.

Pour 240 mL milk, 45 mL sugar, and 2.5 mL vanilla or chocolate flavoring into the small zipper bag. 3.) CAREFULLY seal the bag and shake up the mixture thoroughly. 4.) Put this small zipper bag inside the much larger zipper bag. 5.) In the large bag add enough ice to cover the small bag and add 80 mL of ice cream salt. Take the temperature of the ice:______ C 6.) CAREFULLY SEAL THE BAG!
  • 147. 7.) Get ready to make a phase change! 8.) Don’t hold bag for more than a few seconds as it very cold and damage skin cells / cause frostbite. 9.) Take turns flipping the bag. Hold the bag by its corners. Keep the bag flipping over and over. Remember to keep the bag over the towel at all times. It should take 10 to 15 minutes to freeze. Take the temperature of the ice/water mixture again: ________ C 10.) When you have ice cream, take the smaller bag out and rinse it off with cold water. One partner needs to take the larger bag and its contents to the trash barrel.

  • 203. • What happens when we mix Red Bull with milk in a clear glass container? – Observe for 5 minutes. – Is it a physical or chemical reaction?
  • 204. • Answer! Nasty – Red Bull acidic. The acid attaches to one end of the milk protein. This forms in milk a salt (a bicarbonate). This alters the structure of the protein causing it to drop out of suspension into a curdled mass on top.
