Students examine how every element is classified based on the physical and chemical properties.  In this properties of metals activity students divide into groups, complete a lab and finish a data sheet. 

For this atoms worksheet, high schoolers complete 58 questions about the atomic radius of atoms, the ionization energy, the valence electrons, metals, non-metals and semi-metals and the families of elements.

In this atom worksheet, students complete 60 questions about the trends in atoms such as ionization energy and atomic radius, about valence electrons, about the families of elements, about metals, non-metals and semi-metals, about the...

Students examine and identify biodegradable and non-biodegradable materials. They discover ways in which biodegradable materials can help minimize pollution.

Students determine the contact angle of water on different surfaces. In this physics lesson, students calculate their percent error using a mathematical formula. They explain the advantages of using non-wetting surface for certain...

Students research about the chemical processes involved in cave formation. In this chemistry lesson, students draw or find a cave picture with stalagmites and stalactites online. They write a brief caption and share them with the class.

Students describe properties of various elements. They arrange the elements based on properties in order to explain the organization of the periodic table. They label elements as metal, non-metal, or metalloid.

For this pH worksheet, high schoolers determine how indicators work and what the pH scale is used for. Students learn what happens when non-metals burn in air and metal oxides dissolve in water. This worksheet has 10 problems to solve.

Students recognize that metals, nonmetals, and metalloids have common attributes. They Identify physical and chemical properties. Students define ores and identify where ores can be found.

For this matter worksheet, students compare metals and non-metals, elements, and chemical and physical properties. This worksheet has 22 short answer questions.

How do humans get energy since they aren't mechanical and can't photosynthesize? Learners explore this question by relating potential energy in food to human energy levels. Scholars measure the change in mass and a change in...

In this elements worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with the 25 clues given.

In this periodic table worksheet, students color code the periodic table to show groups of elements, the states of elements, if they are man-made or synthetic elements, if they are radioactive and the number of electrons in their outer...

This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...

For this naming compounds worksheet, high schoolers are given a chart to determine if the compound they are naming is ionic, covalent or polyatomic. Students practice identifying and naming ionic, covalent and polyatomic compounds. They...

The design challenge: develop a method to separate steel from aluminum. The first lesson plan in an eight-part series introduces the class to the grand challenge of ciming up with a method to streamline a sorting process at a...

An organized table charting the different types of chemical bonds arrays this resource. The octet rule, ionization energy, and the naming of compounds are also reviewed. Young chemists answer review questions in multiple choice fashion....

Students collect and categorize solid waste produced in the classroom. They weigh the waste that has been collected over one week's time, and separate it into recyclable and non-recyclable waste. They talk about the role of engineers in...

In this minerals and rocks worksheet, students answer questions about the chemistry of minerals, scratch tests, rocks and the rock cycle, and erosion and deposition.

Students create non-objective art based on the design elements of line, color, balance and movement using tape. This simple lesson plan encourages students to create patterns by overlapping and defining lines on a canvas panel. One of...

In this compounds worksheet, students describe why metals and nonmetals form ionic compounds and why the formation of ionic compounds are exothermic. This worksheet has 5 short answer questions.

In this activity series instructional activity, students read about single replacement reactions and are given a table with the activity series of metals and nonmetals. Students use the activity series to predict if reactions will occur...

In this periodic table worksheet, students are given 12 terms and must match the terms to their appropriate definition. Topics include types of bonds, types of elements, and types of ions.

In this periodic table worksheet, learners answer 10 questions about the periodic table, the elements in the periodic table, the properties of elements and the atomic number, symbol and name of elements in groups of the periodic table.
