In this science vocabulary activity, students solve the clues and insert the words into a crossword. Students insert 8 science words into the crossword.

For this chemistry terminology worksheet, students review and discuss nineteen terms associated with chemistry and then locate and circle each term in a word search puzzle.

In this biologically important molecules activity, students fill in the blank with information about carbohydrates, lipids, and proteins. Students also make notes about nucleic acids.

In this compounds worksheet, students read about the rules for naming inorganic compounds. Then students complete 2 graphic organizers by filling in the compound name, formula, and anion name.

In this science spelling worksheet, learners are given science word definitions, then fill in missing letters to form their matching spelling words. A reference web site is given for additional activities.

Young scholars 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...

Young scholars calculate the Balmer series. For this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Pupils, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.

First graders gain knowledge about solids, liquids and gases by taking a look at the things around them. They have to classify certain picture cards based on which category they feel the picture falls under. As a whole, the class...

Students investigate how long dinosaurs lived on Earth and how that compare to how long man has been on Earth. They discover how scientists excavate fossils.

For this compounds worksheet, high schoolers review how to name inorganic compounds and then complete 2 graphic organizers naming the cations and anions.

Students demonstrate radioactive decay using candy corns. For this Physics lesson, students make predictions, collect data and form conclusions about patterns in radioactive decay.

In this chemical bonding worksheet, students read about the invisible killer, dihydrogen monoxide. Students read about the products it is used in and the problems it causes to the environment. Then students complete 19 short answer...

This page displays the Periodic Table of Elements and allows you to click each individual element for a page that displays in-depth information about that particular element. There are also links to many different games and learning...

This site provides an overview of elements and atoms, the building blocks of matter.

This essay, written for Teachers' Domain, describes the foresight and pattern recognition that Russian chemist Dmitri Mendeleyev used to develop the modern periodic table of elements.

This interactive periodic table developed for Teachers' Domain provides detailed information about the chemical properties of elements and illustrates the electron configurations that determine those characteristics.

A very detailed look at the element Gallium, a member of the Boron Group.

Learn how to read the periodic table of elements as you solve these Math questions about the number of protons, neutrons, electrons or nucleons in an atom of an element. You can choose how many questions to answer, and how complex they...

[Free Registration/Login may be required to access all resource tools.] Explores elements and their different properties, the history of elements, and how atoms relate to elements.

Find out if you know enough about atoms to build them. The goal of the activity is to build an atom of a particular element by dragging the correct numbers of neutrons, protons and electrons into the atom.

Students will use a graph of the relative abundance of elements in the Universe to determine relationships between size of the atoms and their abundance.
