1 4 th Grade 1 st 6 Weeks SIENE Test 1 You are conducting a laboratory investigation on mixtures and solutions. Your lab materials include a balance, a beaker, a hot plate, water, vinegar, Epsom salt, sugar and an unknown substance. USE THE FOLLOWING IGRM TO NSWER THE NEXT TWO QUESTIONS: Proper safety when conducting an investigation should always be a priority. ll of the following are good safety practices EXEPT: Review all safety rules before starting the investigation. Wear protective equipment, such as safety goggles. Make sure your equipment and lab area are clean before beginning the investigation. If a chemical spill occurs, clean it up first, and then report if to your teacher. 2 Students are in the science lab. Their assignment is to make ice. They have a beaker of water that is at room temperature. They decide to place the beaker in the freezer. What are the physical changes that will happen to the water? The water will change from a liquid to a solid. The water will change from a liquid to a gas. The water will change from a solid to a liquid. The water will change from a gas to a liquid. 3 ir has no color and cannot be seen, yet it takes up space. What could be done to show that air takes up space? observe clouds forming measure the air temperature blow up a beach ball or balloon weigh a glass before and after it is filled with water 4 How will the water in the beaker pictured above be affected by heat from the hot plate? It will change from a liquid to a gas. It will change from a gas to a solid. It will change from a liquid to a solid. It will change from a gas to a liquid. 5 The thermometer in the picture above shows this reading. What is the temperature of the liquid? 30 degrees elsius 35 degrees elsius 42 degrees elsius 37 degrees elsius

Water in the air outside the container is cooling and changing from water vapor to liquid. ir above the ice inside the container is warming and changing from vapor to liquid.

2 6 USE THE FOLLOWING IGRM TO NSWER THE NEXT TWO QUESTIONS: Phillip was given 4 blocks of different sizes and different masses shown below. The droplets of water on the outside of the metal container pictured here most likely resulted from which of the following? Water is leaking through the container wall. Water in the air outside the container is cooling and changing from water vapor to liquid. ir above the ice inside the container is warming and changing from vapor to liquid. old air is carrying water from the inside to the outside of the container. 8 Which of the following blocks had the greatest volume? lock lock lock lock 7 9 Which of the following blocks had the greatest mass? lock lock lock lock What is the likely reason that oat is sitting lower in the water? oat is smaller than oat, oat weighs less than oat, oat weighs more than oat, oat cannot float, which makes it sink

3 10 Which item is approximately 4.5 centimeters long? earring finger battery crayon 11 You are on a boat returning from a picnic and drop some of your lunch materials in the water. Which of the following items will NOT float in the water?

4 USE THE INFORMTION GIVE ELOW TO NSWER THE NEXT THREE QUESTIONS. Joey is conducting an experiment to see how temperature affects the rate at which sugar will dissolve in water. Josey started out with four containers of water at different temperatures. Joey then added a sugar cube toe ach container. The results of what happened are shown below: ontainer Temperature of Water ondition of Sugar ube 1 4 The sugar had not dissolved after 10 minutes The sugar dissolved in 7 minutes The sugar dissolved in 3 minutes The sugar dissolved in 1 minute. 12 Thinking about the results of Joey s investigation, you could infer that when adding sugar to tea, while making sweetened iced tea, it would be EST to add ice to the warm tea first, and then add sugar add sugar to the warm tea first, and then add ice ignore the order of adding sugar and ice because the sugar dissolves so quickly you couldn t tell the difference ignore the order of adding sugar and ice because sugar will never form a solution with the tea 14 Joey could make the sugar-water solution faster if he used different types of containers heated the water above 30 used 2 sugar cubes instead on 1 only used water below 4 13 Joey s investigation shows that the colder the water, the faster the sugar dissolves the colder the sugar, the faster the water solution forms a solid the warmer the water, the faster the sugar dissolves the warmer the room, the faster the sugar dissolves
