All scientists like to study things carefully. They like to think and ask questions. They try things out and then see what happens. They use their senses to observe things. They describe their observations with pictures and word word文档格式规范word作业纸小票打印word模板word简历模板免费word简历 s. Scientists use science notebooks to write and draw their ideas and their observations about the things they study. This is your science notebook. You will write and draw some of your ideas and your observations here. Enjoy it! Science depends on scientists like you! ISBN: 0-328-20092-1 - 2006 Edition. Copyright ? 2005 Chicago Science Group.

Materials: What you need to conduct your investigation. Procedures: Logical steps to do your investigation. Data: Number data you collected from your investigation. Conclusion: Using data to answer your investigation question. 4 Two students wanted to find out if pendulums made with different lengths of strings would change how many swings the pendulum made. To help them explore their idea, we are going to do an investigation with pendulums. Question: How does the lengths of the string affect the number of swings made by the pendulum? Circle Your answers: Prediction: I predict that the longer/shorter the string more times the pendulum will swing. length, the Materials: , ruler , 3 weights , 3 pieces of string 5 Procedure: 1. Set up materials as shown in diagram. 2. Hold the 10 in. pendulum parallel to the table and drop. 3. Measure and record the number of swings for each trial. 4. Hold the 15 in. pendulum parallel to the table and drop. 5. Measure and record the number of swings for each trial 6. Hold the 20 in. pendulum parallel to the table and drop. 7. Measure and record the number of swings for each trial. 8. Do the whole investigation again twice. 6 Data Table: (String Length) (String Length) (String Length) 10 in. 15 in. 20 in (Number of Swings) Trial 1 (Number of Swings) Trial 2 (Number of Swings) Trial 3 Circle the numbers in Trail 1 to use in your conclusion. Conclusion: My prediction was right / wrong. From the data we can tell that the 10 inch pendulum swung _____ times, the 15 inch pendulum swung _____ times, and the 20 inch pendulum swing _____ times. So, the longer / shorter the string, the more times the pendulum swung. 7 8 Life Cycles 9 10 Life Cycles Vocabulary Lesson 1 cycle: embryo: life cycle: organism: 11 Human Life Cycle Diagram Paste the human life cycle pictures onto the matching stages below.

In a large family, the oldest generation may include all the great grandparents and great-great aunts and uncles; the next generation includes the grandparents and great aunts and uncles; the third generation has all the parents, aunts and uncles; and the newest generation, the children and cousins. 119 human life cycle The stages that humans go through from the time they are born to the time they die. Beginning at birth, these stages are baby, toddler, child, teenager, adult, and senior. intellectual growth The development of a person’s ability to figure things out and solve problems. larva The offspring of an insect. latewood The dark-colored wood in a tree ring.

You may add to this list during the unit. Write notes as you learn more about your questions. 127 Rock Hound Tape your “Rock Hound” Family Link here. 128 Describing a Rock Draw your rock. Show your rock’s color, shape, texture, and other properties. Think: What could cause rocks to have different colors? 129 Describing a Rock 1. Describe your rock’s texture. 2. Describe your rock’s smell. 3. Describe some other properties of your rock. Think: What could cause rocks to have different textures? 130 Igneous Rocks Igneous rocks form when melted rock (lava or magma) cools above ground or underground. They look different depending on how fast they cool and what minerals they contain. Here are some clues to help you identify igneous rocks. 1. Some igneous rocks form when lava flows at the earth’s surface and cools quickly. Rapid cooling causes the minerals in these rocks to form tiny crystals or natural glass. These rocks may look shiny or glassy. 2. Some igneous rocks form when magma cools slowly deep inside the earth. These rocks may look sparkly because the minerals in them had plenty of time to form large crystals. 3. Some igneous rocks have lots of air holes that make them lightweight rocks. Air bubbles trapped in the cooling lava made these holes. 131 Sedimentary Rocks Sedimentary rocks form when fragments of rocks, shells, sand and clay settle at the bottom of a lake or ocean, and are slowly pressed and cemented together. Here are some clues to help you identify sedimentary rocks. 1. Most sedimentary rocks are soft. Some can be crumbled, split, or broken with your hands. 2. If the rock has big fragments of naturally shaped shells and pebbles, it is a sedimentary rock. 3. Sedimentary rocks can have distinct layers. Sometimes these layers have different colors or textures. 4. If you find a fossil in a rock, you can almost be certain that it is a sedimentary rock. 132 Metamorphic Rocks Metamorphic rocks form when other rocks are changed by heat and pressure deep inside the earth. Sometimes new mineral crystals form as the rock changes. Sometimes existing minerals are softened and reshaped. Here are some clues to help you identify metamorphic rocks. 1. Metamorphic rocks are very hard. Pressure and heat gradually changed the original rock into much harder metamorphic rock. For example a hard and brittle metamorphic rock called “slate” formed from a softer sedimentary rock made from clay called “shale”. 2. Some metamorphic rocks have stripes or bands. 3. Some metamorphic rocks contain pebbles that were flattened and stretched by pressure deep inside Earth. 133 Sorting Minerals From a Piece of Granite 1. Check off each mineral as you find it in your crushed piece of granite. Feldspar ___ Biotite ____ Muscovite ___ Quartz _____ 2. Which mineral did you find the most of? _______________________ 3. Which mineral did you find the least of? _______________________ 4. Did you find any other minerals? What did they look like? 5.

Describe your mineral. 135 Mineral Hardness and Streak 1. Did your mineral leave a streak? Yes No (circle one) If yes, what color was its streak? _____________________ 2. List the letters of all the minerals that your mineral scratched. 3. Write the name of your mineral. ___________________________ 4. Write any other information you learn about your mineral (from a field guide or other resource). 136 Fossil Drawings Look at each picture. Draw the plant or animal that may have made each fossil. Think: How do you think each fossil formed? What do you think the environment looked like when the plant or animal was alive? 137 Fossil Drawings Look at each picture. Draw the plant or animal that may have made each fossil. Think: How do you think each fossil formed? What do you think the environment looked like when the plant or animal was alive? 138 How Petrified Fossils Form Petrified: An organism that has been slowly turned into rock. Petrifaction/Mineralization: When Parts of buried organisms are slowly replaced with minerals and become rock. 139 Petrified Bones 1.
