1 Zahrat Al-Sahraa International School Science Department 2014/2015 Grade 5 Final Exam Worksheet A- Fill in the blanks: 1- All the planets rotate or spin on an imaginary line called. 2- The inner planets are and. But the outer planets are and made up mostly of. 3- All the planets in a solar system revolve around a star in an elliptical path called. 4- are rock and iron objects that orbit the sun. Pieces of rock that break off of it are called and travel through space. Most of these pieces burn up in Earth s atmosphere causing a streak of light called. But some of them that reach Earth s surface are called. 5- The preserved remains or traces of a living thing is called a. It can be made of an organism s parts such as,, and shells. Or it can be made of an organism s parts such as and organs. 6- Insect parts and even whole insects are often preserved in. 7- Footprints are examples of. 8- Sometimes fossils form occurs as minerals, such as quartz, replace the material that made up the organism. This kind of fossils is called. 9- The mold and cast fossils are made when an organism is pressed into soft mud, leaving a hollow space called a. Then a forms if the mold is later filled with. 10- Coal forms from dead. It is and made from pure. 11- Oil and natural gas are formed from two elements: and. 12- Scientists who study fossils are called.

2 13- The organisms that look like they haven t changed much over time are called. 14- An energy riche resource formed from the buried remains of once-living organisms is called. 15- Scientists who study fossils are called. 16- Air is matter because it has and it has. 17- is the amount of matter in something, and is the amount of space something takes up. 18- All matter has such as texture, odor, and color. 19- Density is found by dividing the of an object by its. 20- Solid, liquid and gas are the most common states of matter on Earth. A liquid is a substance that has a definite but not a definite, and its particles slide by each other. A does not have a definite shape or volume, and its particles are from each other. 21- Matter has two kinds of properties. Some properties can be observed without changing the type of matter, these are properties. Other properties cannot be observed without changing the identity of matter, these properties are. 22- Matter can change without changing the type of matter; this change is called a. 23- When change of the identity of matter occurs, we can say that the matter is undergoing a change. The process in which new substances are formed during this change is called a. 24- A is a combination of two or more substances that keep their. 25- If the mixture has the same composition throughout it s called a. 26- Both mixtures and solutions are a change. 27- Not all solutions are liquids. It can be a solution of different gases such as, or a solid solution such as formed from solid copper and solid zinc. 28- Mixtures of metals are called.

3 29- Adding chromium to steel will make steel. 30- Adding metals such as Nickel or Titanium to steel can keep it from. 31- Adding carbon to steel will make it. 32- A has holes that some matter can pass through. But a has very tiny openings that only the smallest bits of matter can pass through. 33- Forces are measured with a in units called. 34- Gravity is a force of between two objects. The size of this force as the mass of the object increases. It as the distance between the objects increases. 35- is a force that opposes motion. It acts between two objects that are. It also can exist between air and a moving object, this is called. 36- are forces on an object that are in size and in direction. They cancel each other. 37- An object s acceleration depends on the object s mass and the force applied to it. The larger the force, the the acceleration. And an object with less mass speeds up than an object with more mass. B- Gravity & Friction: What is gravity and what does it do? What is friction? Would there be more friction when rolling a ball over concrete, grass or sand?
