Kesler Science Station Lab Elements, Compounds, & Mixtures If you have never used my Kesler Science Station Labs before please download the FREE Start-Up pack from my TPT store. It will provide you with all of the signage and best practices in order to run the station labs in your classroom. The large directions cards included in this file are intended to be read by the leader of the group once the students get to the station. The smaller task cards can be read by another group member. I prefer that each student do their own lab write-up (included at the end of this file), so that they may use it for reference at a later date. The answer key is provided at the end of the document. Lastly, if any of the internet resources no longer work for some reason please let me know via email at chris@keslerscience.com. I cannot guarantee that all resources will be available, but I tried to choose ones that have been around for many years.
Kesler Science Station Lab Elements, Compounds, & Mixtures Teacher Directions Explore It! I will spend much of my time at this station making sure students are understanding the concepts. You will need 3 containers and some Legos (1 with same color bricks, 1 with a mixture of colors, and 1 with compound molecules) It s OK to be wrong at this station. It s meant for exploration of new information. Organize It! All of the cards are included for this station. The cards for this activity are attached near the activity. Students should be encouraged to do the Research and Explore station before attempting this one. I like to label the backs with set numbers because they will get mixed up. Place this one next to the Explore It! Station. Illustrate It! Make sure to include colored pencils or crayons at this station. Read It! Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces Watch It! The video is on YouTube and my Google drive. Use YouTube unless your school is blocked. The original link is https://www.youtube.com/watch?v=fsscqfvgt mi Note that both URL s are case-sensitive. Write It!

Read It! Station Directions Each member of the group will read the passage and answer the questions from the task cards on the lab sheet in the Read It! section. It is important to remember that the answers will come directly from the reading passage.
Steel Production Steel is an alloy of iron with about 1 percent carbon. It may also contain other elements, such as manganese. Whereas pure iron is a relatively soft metal that rusts easily, steel can be hard, tough, and corrosion-resistant. The elements are not chemically combined together. Used to make almost everything from skyscraper girders, automobiles, and appliances to thumb tacks and paper clips, steel is one of the world's most vital materials. Among all the metals, iron is second only to aluminum in natural abundance, making up 4.7 percent of the earth's crust, and occurring mainly as its various oxides. The main product made from iron is steel, the least expensive and most widely used of all metals. Over the years various countries have excelled in making steel. During the eighteenth century a relatively small amount of steel was made, but Sweden was the main producer. In the nineteenth century Great Britain became dominant. In the twentieth century the United States was the largest steel producer in the world until about 1970, when it was surpassed by the Soviet Union. At the start of the twenty-first century, China led the world in steel production. Three primary installations in an integrated steel plant are the blast furnace, the steel furnaces, and the rolling mills. The blast furnace converts iron ore to pig iron; the steel furnaces convert the pig iron to steel; and the rolling mills shape the steel into sheets, slabs, or bars. The three top steel producers in the world are China, the United States, and Japan, in that order. The United States and Japan each produce around 100 million tons (90 million metric tons) of steel per year, and China had an output in 2000 of about 140 million tons (127 million metric tons). Iron and steel make up approximately 90 percent of all the metal produced in the world. The largest steel company in the United States is United States Steel, which produces about 20 percent of the country's steel.
After reading the passage, how can you classify steel? Iron is the most abundant metal found on Earth A. Compound B. Mixture C. Element D. Electrons A. First B. Second C. Third D. Fourth Who are the top 3 producers of steel in the world? A. China, Russia, U.S. B. Russia, U.S., Japan C. U.K., U.S., Japan D. China, U.S., and Japan A. Iron B. Carbon C. Manganese D. Silver What element is steel mainly composed of?

How is a mixture different from a compound? YouTube How are the atoms in a compound held together? 1. H 2 0 2. H 4 3. Fe + S Based on the information from the video, classify the following as mixture compound or element.
Research It! Station Directions Each member of the group will go to the website listed on task card #1 Complete the task cards in order. Every student will answer the questions from the task cards on the lab sheet in the Research It! section.
1. Go to http://goo.gl/32wd3u 2. Play through the interactive about elements, compounds, and mixtures 1. How many elements have to be present for a compound to form? 2. How do you know the difference between a compound and mixture? 3. Name 3 things that would be considered a compound.
Explore It! Station Directions One member of the group will read the task cards in order. The group will be responsible for completing each of the tasks that are being read. Each member of the group will then write their conclusions down on the lab sheet in the Explore It! section.
In front of you there are 3 containers that are labeled elements, mixtures or compounds. Each Lego piece represents 1 atom. Look in the element container. 1. What do you notice about all of these Legos? An element is a pure substance that cannot be broken down into any other substance. It is represented on the periodic table by a symbol. For example, O is Oxygen. 2. Copy the element definition to your lab sheet. Look in the mixture container. 1. What do you notice about all of these Legos? A mixture is a combination of many different elements but they are not chemically combined and can be separated. 2. Copy the mixture definition to your lab sheet. Look in the compound container. 1. What do you notice about all of these Legos? A compound is when one or more elements have been chemically combined together through a chemical reaction to form a new substance. An example is H 2 O (water). You can also count the capital letters. If there are 2 or more capital letters it is a compound. 2. Copy the compound definition to your lab sheet.
Illustrate It! Station Directions Each member of the group will draw a quick sketch on the lab sheet that shows they understand the concept that is being taught. Use the colored pencils and markers that are provided. The directions for the sketch are provided on the task card at the table.
Illustrate It! Station Directions On your lab sheet draw a model of an element, compound, and a mixture. Be sure to label them correctly. Use different colored circles to represent different atoms.
Organize It! Station Directions It is recommended that you have completed at least two of the following stations before working at this station. -Read It! -Explore It! -Watch It! -Research It! Each group will organize the cards. Each of the cards will be used. Once you are complete please have the teacher sign off on your lab sheet. Please mix up the cards again before the next group arrives at this station.

Compounds are 2 ore more elements that have been chemically combined together to form a new substance. You can recognize them in a chemilcal formula because more than one element will be present. You can also count the capital letters in the chemical formula. 2. There are 3 elements present in glucose. I know this because there are 3 capital letters in the chemical formula. 3. An element is a pure substance that cannot be broken down into any other substance. You can find a list of all known elements on the periodic table.
