Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

The fifth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program defines dead zones and how they form. Pupils then examine data from the Gulf of Mexico to determine dead zone formation.

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

This compact collection of slides explains the history and use of the mole unit. Relative atomic mass, as John Dalton understood it, is explained. Avogadro's number is also introduced. The mole, or the unit for the amount of a substance,...

An online resource, this worksheet has your chemistry learners complete four data tables with information about atoms and chemical bonds. The first table addresses atomic number and mass, as well as numbers of protons, neutrons, and...

In this science worksheet, students explore the learning outcomes for a unit on chemical reactions. Students define 60 vocabulary words and answer a list of questions for each topic.

Designed to be a study guide or self assessment for high school biologists, the worksheet has good questions about cell chemistry, but would need to be reformatted if you want your kids to write their answers on the paper. There are also...

In this acids and bases worksheet, high schoolers review the characteristics of acids and bases, pK values, factors that change the rate of reactions, and catalysts. This worksheet has 17 multiple choice questions.

Opening with a chart of common polyatomic ions, and finishing with an explanation of how  to name polyatomic ions, this presentation is to the point. The links on the vocabulary page do not work, leaving you only a few slides to...

Students collect and look at rocks and write down information about them in science notebooks. They make comparisons and sort the rocks according to their properties, and then discuss their findings with their classmates and put them on...

In this chemistry worksheet, students use the clues given at the bottom of the sheet to complete the crossword puzzle on mixtures. There are 18 clues to solve on the sheet.

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties instructional activity students complete a demonstration .

A short paragraph helps explain how covalent bonds are formed, and then your class will complete the Electron/Dot and Structural diagrams for the molecules given.  The valence diagrams will reinforce understanding. This activity...

Students discuss background information presented by the teacher and read dictionary definitions for the words "organic" and "synthetic." In this gardengin lesson, students complete a worksheet on the material. Students grow and compare...

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

Though this is meant to be second in a two-part lesson, the two are not dependent on each other. Pupils play the roles of visible light rays, light or dark surfaces, and carbon dioxide molecules. They interact and react according to...

For this chemical reactions worksheet, students follow a flow chart to determine what type of reaction is occurring. Students then classify reactions and balance the equations. This worksheet has 2 short answer and 10 fill in the blank.

In this chemical reactions worksheet, students learn about the 5 types of chemical reactions as well as endothermic and exothermic reactions. Students are given 5 equations to balance and they identify the type of reaction for each...

Students study polyatomic ions and write binary and ternary ionic chemical formulas. They explore putting together different monatomic ions and coming up with as many chemical formulas as possible. They play a game similar to memory...
