All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

Putty is proof that learning can be fun! Share the wonderful world of polymers with your class through an experiment. Young scientists create their own silly putty, then examine its properties.

Go get the American Dream lifestyle! The 19th lesson in a 22-part series exploring American history shows learners the post-WWII economic boom. Using primary sources, photographs, and cartoons, groups discuss their findings and present...

In this chemistry instructional activity, students select the best answer for 26 multiple choice questions from the drop down box. They describe how elements are arranged in the periodic table.

In this atom worksheet, high schoolers answer 31 multiple choice questions about the structure of atoms, the periodic table, the reactivity of elements, orbital diagrams and the families of elements.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Learners diagram nuclear power plant, describe process for generating electrical power, discuss nuclear disasters in the 20th century, and draw conclusion about value of nuclear power for the future.

Eighth graders investigate the different elements of the Periodic Table. In this chemistry lesson, 8th graders pick an element to research, then present to the class using a powerpoint presentation or a poster.

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

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...

High schoolers will review a semesters worth of material on this final chemistry review. Information ranges from naming isotopes to pH and molarity.

Students study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...

Students complete a Webquest which investigates the chemistry in items such as shampoo. They research the Internet, perform a lab experiment, and write a scientific lab report with their findings. Upon completion of the activities, the...

In this atoms activity, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).

In this science worksheet, students use a periodic table to complete the first four rows of a chart. Students use the Internet or research books to complete the last column.

In this thermochemistry worksheet, students solve a variety of problems including finding heats or reactions, determining specific heats of substances, finding the amount of energy released in a calorimeter determining the final...

Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...

For this current events worksheet, students analyze a political cartoon about the nuclear war threat and respond to 3 talking point questions.

Students analyze data taken from proteomic experiments. In this biology lesson plan, students explain the importance of bioinformatics tools in the study of proteins. They evaluate scientific results using math and computer software.

This is a chart of the elements including the atomic mass, atomic number, symbol, half-life, and more.

Are all atoms of an element the same? How can you tell one isotope from another? Use the sim to learn about isotopes and how abundance relates to the average atomic mass of an element.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will be asked to define atomic number, mass number and understand how isotopes differ from one another. They will be able...
