Images of the Past: Engineering - Building a Tower During this activity your students will learn about the process of extracting gold ore from the earth and extracting gold from the ore. The students will look for historical clues in the video footage to help identify the age of the video. The students will then participate in a hands-on activity in which they will build a simple tower that will convey the importance of starting with a solid foundation/base when designing a machine or building.

Images of the Past: Compound vs. Mixture - A Simple Separation During this activity your students will learn about compounds and mixtures. They will learn how a chemical change (reaction) is needed to break apart a compound and how mixtures can be separated by physical procedures. Your students will learn how workers at the Golden Reward Mine used a cyanide solution to chemically remove gold and silver from the ore they mined. Then your students will complete an activity in which they will use physical techniques to break apart a mixture.

Images of the Past: Density Bowling During this hands-on activity your students will use household items to investigate density. They will complete an activity in which they will construct a density tube and use it in a game of Density Bowling. This is a great activity because the students will remember this activity every time they are looking for something in their kitchen. This is a density experiment that will last forever. They will also learn about the Lead Opera House and Recreation Center opened in 1914 as a gift from the Homestake Mining Company to the people of Lead.

Images of the Past: Land Subsidence – Support During this activity your students will learn about the issue of land subsidence, which leads to topographical changes. Subsidence is due to poor backfilling/stabilization practices during the mining of gold. Then your students will complete an activity in which they will use materials like sand and coffee grounds to understand the importance of backfilling and stabilization.

Images of the Past: Reaction Rate - Surface Area During this activity the students will learn about a tragic 1930 fire at the Ellison Shaft, Homestake Gold Mine, which claimed the life of two men. They will also use household items to investigate how an increase in the surface area of a solid reactant increases the reaction rate of a chemical reaction. Finally, they will learn how adding chemicals like aspirin to a sewer system is damaging to the environment and water supply.
