_________________ Period______ Date______ Objective: Examine the dissolving process and compare how different substances dissolve. Log onto a computer and Google “Phet.” Click on the first site listed, once at the site click “play with sims,” then click “Chemistry.” Find the “Sugar and Salt Solutions” simulation on the phet site and click it, then click “run now.” Define the following terms: (use your book or the internet) Solution-chemistry fluid with substance dissolved in it: a substance

Check “show battery” and “show cores”, watch what happens, adjust some variables 1. Why do electrons (blue dots) move? The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move because they are being attracted towards the positive side of the battery and thus move because of the attraction in the battery. 2. What does the Ammeter (on the left) measure? How is this shown in the sim? It measures the rate

If you haven’t started the simulation already click here to start the simulation. Then answer the questions below. Please insert your answers to each question in the gray boxes immediately after the question to make it clear to the grader which question you are answering. I After the simulation loads click Start. Describe what you see in this simple sun-planet system. Specifically, what happens to the central object (the Sun)? The sun begins to move Can you explain why the central object

Wire Resistance and Ohm’s Law PhET MiniLab Introduction: When an electrical potential exists in a circuit, a current may flow. Current is the flow of electrons in a circuit. Resistance in the circuit slows the flow of the electrons, reducing the current in the circuit. We will use the mathematical form of Ohm’s Law frequently when we investigate electric current and circuits later in this unit. Additional Material Needed: Clean Drinking Straw Procedure Part I Wire Resistance: • Blow through

Name_________________________ Snell’s Law—PhET Simulation 1. Go to the PhET website. https://phet.colorado.edu/ 2. Choose “play with simulations.” Next, chose >Physics, >Light and Radiation, and choose >Bending Light. 3. Learn how to turn on the laser. Play with moving the angle to change the angle of incidence. Figure out how to use the protractor to measure angle of incidence and angle of refraction. Use the light intensity meter to figure out how to measure the percent of the ray that

Name:____________________ Density, Buoyancy, and Force Diagrams PhET Lab (rvsd 2/2011) Introduction You’ve heard that oil floats on water. You also know that ice cubes normally float in a glass of water. Why? What causes some things to float in water (corks, ice, dogs) and some to sink in water (rocks, metal spoons, mobsters)? Density is often described as the amount of mass crammed into a volume, and is illustrated by the formula shown below. The units for density are expressed g/cm3, g/mL

cánh gà ra làm 3 khúc, rửa sạch, để ráo rồi cho cánh gà vào một tô lớn, rắc muối tiêu và trộn đều rồi cho ra khay nướng. Rưới 1/2 chỗ syrup lên cánh gà: Bật lò ở 180ºC, nướng mỗi mặt gà khoảng 10 - 15 phút. Mỗi 10 phút bạn lại lấy khay nướng ra và phết đều chỗ syrup còn lại lên cánh gà để nướng xong cánh có màu vàng đẹp nhé! Cánh gà nướng có vị ngọt ngọt cay cay rất dễ ăn. Nếu nhà có trẻ con bạn hãy giảm bớt lượng ớt hoặc thay thế ớt quả với tương
