Penny density lab

Author Profile Summary In this lab, students will learn how to measure the volume and mass of an object and use that to compute density. They will then use that density to talk about experimental errors and accuracy of measurements. As they do this project, they design their own data table to show how they computed the density of a penny.

With such little snow, the ground has been exposed and my little rock hounds have been collecting rocks again. I thought we'd revisit the types of rocks again sedimentary, metamorphic and igneous - but this time give them a more active and visual way to think about how each are formed.

There are many examples of creating rocks from crayons, but this pdf from the the Exploratorium is very helpful. Unwrap the crayons and use the sharpener to create shavings. You can also try to make the shavings use a penny or a plastic knife, although we found that the sharpener was easier and more productive than the penny or knife especially for the little ones.

Make sure to keep the shavings separate from each other at this point.

Sedimentary rocks Sedimentary rocks are formed from sediments tiny rock particles that were created by weathering or erosion that were layered and then compressed. To replicate this with the crayon shavings, take one of the aluminum foil squares and have your child sprinkle each of the colors of shavings into the middle of the square, one at a time so they will form the layers.

Fold the aluminum foil up tightly around the shavings and then compress it. To do this, they can press on it with their hands, step on it, place it in a clamp or use your creativity to think of other ways.

This does take a while to get the crayon pieces to stick together and we found that a little body heat "helps" the process along. Carefully unfold the foil and remove the sedimentary rock with care as this is the most brittle of the rocks that you are making.

A sedimentary crayon rock. To mimic this, take another square of aluminum foil and pile all four colors of shavings in the center.

Fold up the sides of the aluminum foil to make a boat.

Pour boiling water into a mug adult job! Quickly remove the boat and fold the foil in half so that the shavings are compressed a bit. Let it cool and solidify and then open the foil and remove the metamorphic rock.As you learned from the “Hollow Penny” activity, pennies minted before are pure copper.

Newer pennies are actually almost entirely composed of zinc, but the thin coating of copper on the outside makes new pennies look very much like they are made of copper.

A cup of gold colored metal beads was measured to have a mass grams.

By water displacement, the volume of the beads was calculated to be cm Given the following densities, identify the metal. You can now purchase “Numberopedia: What's Special About This Number” by G. Sarcone in pdf format! pages filled with an incredible variety of fun facts on numbers (and their peculiar properties), both mathematical and cultural, tantalizing problems and anecdotes.

There is much to learn for. Copper is incredibly useful in industry for wiring, heat sinks and coins, and in brass and bronze alloys. But this sample is completely useless; it's simply a pretty hand-hammered ball, pleasant to hold and behold.

Jan 27,  · Igneous rocks Igneous rocks are formed when magma (molten rock) cools and solidifies. To make an igneous crayon rock, repeat the steps for making the metamorphic rock, except leave the the aluminum foil boat floating on the hot water for a minute or more until all Author: Momma Owl's Lab.

Sample Traditional Lab Report - Density of Pennies Hypothesis (Based on the instructions provided) The density of pennies made before will be greater than the density of pennies made after Data Table 1 Trial Mass of 10 pennies made before Mass of 10 pennies made. Since the density is the amount of mass per volume, and the volume of a penny can be determined (approximately) from the thickness and diameter, it follows that measurements of the mass, the thickness and the diameter of the penny should be enough to calculate the density. We are pleased to announce IAGARB will be holding its 31 st annual meeting with a return to the Red Lion Downtowner in Boise, Idaho!. Registration for Workshops and Events can be found on HERE.
