I realize that this LAB exists all over the place, but my version is simple and follows the Scientific Method. The student sheets have them collecting measurement DATA on each object and liquid first, before layering them in the cylinder. I also include a page of teacher suggestions for what materials are easiest to use, from many years of experience. They will Calculate Density of each substance or object and then create a number line of Density once their Tower is complete. My Conclusion Questions always reach up for high level thinking-- to Analyze and Synthesize information, they will compare their results with the Densities of other known substances and draw their own Conclusions as to whether solids are always more dense than liquids. I have included several FREE items that I hope you will enjoy from my new Matter & DENSITY complete UNIT--5E's+way more! I include the Task Cards, my sample Lesson Plans and Weekly Goals sheet to preview vocabulary, and my Density and Physical vs Chemical CHANGES Choices BOARD for differentiation. Please let me know what you think:) Maybe you'll do me the honor of allowing me to plan your Units in the future?
