![]() The cast is a natural occurring replica of the actual organism. A cast fossil may form when sediment fills in a hollow mold fossil. The surrounding mud and sediment hardens around the dead organism and only an imprint of it remains after decomposition. Mold fossils are hollow impressions left by a plant or animal. Trace Fossils reveal information about the animal's lifestyle and include fossilised footprints and fecal matter. 101 Great Higher-Order Thinking Questions for Reading. It is an important point that the organism has been replaced by mineral deposits as some children will think that the original organism is inside the fossil. ![]() The soft parts of the body like the skin and muscle usually decompose before fossilization can occur. The hard parts of the body like the bones or stems were trapped in rock and effectively preserved. True Form Fossils are made of an actual plant or animal. Students each obtain 2 rock samples from a collection of 20 for the lab. Sedimentary rocks are made of sand, shells, pebbles, and other. Higher level thinking: You saw in the video that as the glacier melts. You can use NASAs rock cycle worksheets for a more detailed explanation of the various factors that influence rock formation. It is worth noting that there are three main types of fossil: the true form fossil, trace fossil and mold fossil. Metamorphic rocks form under the surface of the earth as a result of intense pressure and heat. Answering questions along the way of the virtual field trip. ![]() Making your own fossil is a way to help children see how fossils are formed. The activity idea on page 32 involves making a replica of a fossil. State true or false: In the rock cycle, old rocks are converted into new ones. Looking at fossils of plants and animals may help children see that fossils are not 'bits of bones' but were once living creatures. Higher-order thinking questions are questions that require students to apply, analyze, and evaluate information rather than simply recall it. We have allocated Levels to SAT-type questions the Extension questions are a little. This is a treasure chest of ideas for teaching about fossils, containing ideas for use in class or for an inset activity to help teachers prepare for this new topic.
