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 activity, 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...

Students 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 levels of...

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...

Study corrosion on bronze statues with a hands-on lesson. As pupils place a penny in water with salt, they observe the changes in the penny throughout a period of a week. They then analyze the pre-conservation and the...

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...

Students 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 formulas...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Is your acid-base chemistry lesson plan a little ho-hum? Spice things up with puzzles! Young chemists manipulate facts about acids and bases to solve a series of interactive puzzles. The activity combines content knowledge and...

From polyhedrons to platonic solids, here is a lesson that will have your classes talking! As an introduction to platonic solids, scholars cut and fold nets to create the three-dimensional solids. They use an interactive component to...

The need for a counting unit is mentioned as you introduce the mole to your young chemists. Use this presentation to explain Avogadro's number and describe the incredible quantity it represents. Lecture notes are included for most of the...

Young scholars study the Periodic Table to investigate basic properties of metals used to make coins. They discuss how historic events like the Civil War and Gold Rush had a direct impact on the trime.

In this resources worksheet, learners compare and contrast physical and chemical properties and changes. Students review the periodic table, pattern of atomic numbers and chemical reactivity. This worksheet has 56 short answer questions.

Students identify the periodic table trends and predict material properties. They also design and conduct simple experiments and test material properties. Finally, students compare and contrast material properties and that chemical...

Ninth graders review and discuss the Periodic table and its 53 elements. They choose one element to become an expert on and then create a written Report in the form of a poster about their choosen element to be presented to the class.

Young scholars study the elements of the Periodic Table as they relate to the building blocks of the body. They experiment to measure the amount of iron in the body.

In this chemistry activity, students sketch several diagrams of different peptide chains. Students sketch diagrams of galactose and fructose.
