Description
What our Elements: Metals lesson plan includes
Lesson Objectives and Overview: Elements: Metals is a high-interest reading comprehension lesson plan. As such, students will practice various close reading and comprehension skills. In addition, they will learn about the largest collection of elements in the Periodic Table. This lesson is for students in 5th grade and 6th grade.
Classroom Procedure
Every lesson plan provides you with a classroom procedure page that outlines a step-by-step guide to follow. You do not have to follow the guide exactly. The guide helps you organize the lesson and details when to hand out worksheets. It also lists information in the yellow box that you might find useful. You will find the lesson objectives, state standards, and number of class sessions the lesson should take to complete in this area. In addition, it describes the supplies you will need as well as what and how you need to prepare beforehand.
Teacher Notes
The paragraph on this page provides a little more information or guidance on what to expect from the lesson. It explains that you can teach this lesson in a whole-class setting or as an independent, small-group activity. You can use the blank lines to record any thoughts or ideas you have as you prepare.
ELEMENTS: METALS LESSON PLAN CONTENT PAGES
The Elements: Metals lesson plan contains one content page. Thousands of years ago, ancient people discovered metals like gold and copper by finding shiny rocks
in the ground. Gold was one of the first metals used by humans because it was easy to shape and didn’t rust. Later, people learned how to melt metals out of rocks and mix them to make even stronger materials. The discovery and use of metals helped create tools, coins, and buildings that changed the world.
What Makes a Metal?
What makes an element a metal? Metals have special features that make them different from other types of elements. They are usually shiny, strong, bent, or stretched into various shapes without breaking. They also conduct heat and electricity well, so we use them in wires and cooking pots. For example, electrical wiring contains copper because it lets electricity pass through easily. At the same time, aluminum is excellent for making soda cans because it’s lightweight but strong.
There are several different types of metals on the Periodic Table, and each group has special properties. Alkali metals, like sodium and potassium, are very soft and react quickly with water, so they must be handled carefully. Alkaline earth metals, such as calcium and magnesium, are a bit harder and essential for strong bones and fireworks. Transition metals, found in the middle of the Periodic Table, include familiar elements like iron, copper, and gold. They are known for being strong, shiny, and good at conducting electricity. Other types, like lanthanides and actinides, are found in a separate block at the bottom of the table and are often used in things like magnets and nuclear energy. Each type of metal has different uses, but they all play essential roles in our world.
One of the most incredible things about metals is that some can mix together to form alloys, which are even better than single metals. An alloy is a mixture of two or more metals. For example, steel is made from iron and some carbon. Bronze is another famous alloy made from copper and tin. It was so important in history that there’s even a period named after it—the Bronze Age!
Why We Need Them
The metals on the Periodic Table are some of the oldest and most valuable elements known to humans. They help build our homes, power our electronics, and make our vehicles move. Scientists who study metals, called metallurgists, learn how to make metals better and use them in new ways. Because of what we know about metals and where they are on the Periodic Table, we can keep inventing new tools, machines, and gadgets that help people worldwide.
ELEMENTS: METALS LESSON PLAN WORKSHEETS
The Elements: Metals lesson plan includes two worksheets: an activity worksheet and a review worksheet. Each one will help students solidify their grasp of the material they learned throughout the lesson. You can refer to the classroom procedure guidelines to know when to hand out each worksheet.
MYSTERY METALS ACTIVITY WORKSHEET
For the activity, students will observe several metals. They won’t know what they for sure, but they will make observations about the color, luster, weight, and flexibility of each sample. They will conduct a series of tests and then answer reflection questions based on what they learned.
REVIEW WORKSHEET
The review worksheet lists 5 questions based on the content. These questions all relate to the content pages, so students will need to refer to them often for the answers. In addition, each question provides which reading tool the question corresponds to, such as text feature, vocabulary, or comprehension.
Worksheet Answer Keys
At the end of the lesson plan document is an answer key for the practice worksheet. The correct answers are all in red to make it easier for you to compare them with students’ responses. If you choose to administer the lesson pages to your students via PDF, you will need to save a new file that omits these pages. Otherwise, you can simply print out the applicable pages and keep these as reference for yourself when grading assignments.
