In this chemistry worksheet, students use the clues given at the bottom of the sheet to solve the crossword puzzle on the Periodic Table. They describe the number of protons and electrons some elements posses, as well as identify their...

Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

In this word search learning exercise, students locate nine elements from the Periodic Table. The list of elements include palladium, silver, and rhodium.

Students identify the properties of transition metals. In this chemistry lesson, students research facts and uses of one aluminum product they choose. They create an advertisement highlighting aluminum's useful properties.

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

In this chemistry worksheet, students complete a crossword puzzle with 25 questions on chemical reactions. They identify common terminologies used in describing chemical reactions.

In this atoms worksheet, students calculate the formula mass for chemical compounds. This worksheet has 12 problems to solve.

In this chemistry worksheet, students select the answers to 26 multiple choice questions from the drop down box. They describe the physical and chemical properties of transition metals.

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

Using a chart of student test grades as an example, curious chemists learn how to calculate weighted averages. They apply this knowledge to elements on the periodic table. As practice in calculating average atomic masses, learners...

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...

In this chemistry worksheet, students identify and write how many significant figures they would use for each problem. Then they round the answers to the appropriate number of significant figures. Finally, students calculate the mass of...

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Young scholars determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

Students describe how elements are arranged in the periodic table. They compare metals, nonmetals, and metalloids based on their properties and on their location in the periodic table. Finally, students identify and describe the...

In this chemistry worksheet, students identify and locate various vocabulary terms relating to the elements found in the periodic table. There are 116 chemistry terms located in the word search.

One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

Young scholars recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical...
