This activity will allow students to produce a "marketable" product made from minerals in a product that many people use daily. Students will make their own toothpaste using the minerals, calcium carbonate and sodium bicarbonate. Students get to test their product against the basic toothpaste that many people use. The activity and lesson familiarize students will the natural compounds that are used to make many everyday things. Students will see that the combination of these two minerals makes something profitable. Students can also compare the prices of toothpastes to integrate math and to learn about the economy. The activity can be used when we are learning about minerals and natural resources, geoscience, or how communities use science.

This is a link to the US Geological Service's website. The education portion is really neat. Since i have met my boyfriend, he is a miner, I have become more and more interested in rocks and the earth. This webpage makes it easy to find what you need. Their resources are broken down into categories (K-6, 7-12, and undergraduate). The best part about this is there is a place to look at 3-D pictures of major landmarks. You would need your own glasses, but I think if these were projected on a smartboard, it would be a great way to show students what Mother Nature can accomplish.

This activity helps provide students with a simple understanding of why there are different types of soil. The students will be given a chewy chocolate chip cookie, and a regular crunchy one. They will examine each cookie and describe their characteristics and properties. Next, the students will smash the cookies with their hands to replicate the process of rocks weathering. Now that they have soil, they will compare the properties of both types of soil and form conclusions. Using a chewy chocolate chip cookie and a crunchy one represents the different minerals found in soils, and how it impacts its appearance, texture, and many other characteristics. Once the students have completed this activity, they will be able to enjoy a cookie! I selected this resource because I think it is a very straight forward way of learning about the different types of soils. Using these types of cookies really makes the concept easier to understand. This activity will not cost a lot of money, which makes it very valuable to me. We will do this activity at the end of our soil lesson in science.

This activity could be used at the end of a unit on rocks, minerals and the layers of the earth. Students build their own structures made out of mini marshmallows and toothpicks. The students then place their structure on top of the jello that's sitting in an aluminum pan. The students then shake the pan to see what structures survive the "earthquake". I chose this activity because I thought it would be a great hands on experiment for students to see the damaging effects of what can happen to buildings after an earthquake. Another plus to this activity, is possibly sparking the interest of future architects.

An engineering design challenge!
