the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails * Three alligator clip/wire units (alligator clips connected to each other with wire) * One simple low-voltage bulb with bulb socket IV Procedure: 1. Remove the battery from the battery compartment

Amplifier DC Voltmeter in a Digital Multimeter Copper Coins and Zinc-Galvanized Nails Procedure: 1. Set the multimeter to the “2V” (direct current) range. Turn it on. 2. To measure its voltage‚ insert the black and red probe to the potato. To increase the voltage‚ inject a coin and a zinc-galvanized nail to the said fruit‚ and connect it to the multimeter using the alligator clips‚ have the black probe to the zinc-galvanized nail while the red probe to the copper coin. 3. Read the value. b. Lighting

Physics assignment Aim To determine which factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor

TOPIC 2 Metals The History of Metals * Uses of metals through history: * Copper Age (3200-2300 BCE) – copper and tin were most common metals‚ and were used for ornaments‚ weapons and tools. * Bronze Age (2300-700 BCE) – copper‚ tin and bronze were used for tools‚ weapons and transport. They produced bronze by heating copper and tin with charcoal. * Iron Age (1000 BCE – 1 CE) – iron steel and lead was used for tools‚ weapons and pipes. Iron is much harder than bronze.

Title: Calculating the Atomic Mass of “Pennium” Purpose: The purpose of this lab is to calculate the atomic mass of “pennium” using pennies made before 1982 and pennies made 1982 or after. Hypothesis: The atomic mass of the pennium will be the average of the average masses of a pre-1982 penny and a post 1982 penny. Procedure: 1. Obtain a bag of pennies 2. Determine the total number of pennies in the bag. Record the value. 3. Sort the pennies by date into 2 piles. One pile should consist

There are‚ and always have been many theories on how and why Oetzi the Iceman was killed. Many theories say he was murdered by an enemy‚ tracked down and hunted after surviving a battle with an enemy clan‚ or even that he was sacrificed to the god of the mountains. There is no way to surely determine how he died to a tee‚ and ever since the Iceman’s discovery‚ new evidence has been consistently presenting itself‚ suggesting new and improved theories‚ while also dismissing the old.

volume in proportion to the number of pennies being used‚ the slope of the line equals the density of one penny. 3. The density of copper is 8.89‚ while the density of the Pre-1982 Pennies is 8.17. This means that although the penny’s density is close to that of copper‚ the penny is not all copper‚ but an alloy made up of different metals‚ but primarily of copper. 4. The density of the Post-1983 Pennies is 7.11. The metal Zinc is close to having the same density as these pennies because it has
