Students decompose glucose and write an equation for the reaction. In this decomposition reaction lesson plan, students burn a sample of glucose and test the products for water using cobalt chloride paper. They write a balanced equation...

Learners watch video, The Elements, research information about elements using both the Internet and CD-ROM program, and create atoms out of gumdrops and licorice.

In this molecular shapes worksheet, students read about how to predict molecular shapes in molecules based on the number of electron pairs and the VSEPR theory. Students are given twelve molecules, they draw the Lewis structures and...

In this periods, groups, valence electrons and masses worksheet, students are given information about all these components of the periodic table. Students identify 4 elements in specific periods and groups, they find the valence...

Students describe how the mass of a radioactive isotope changes with time and the factors that affect the rate of radioactive decay. They write nuclear decay equations to represent natural transmutation. This activity is accomplished...

Students interpret basic chemical formulas. When class begins, students interpret a "chemical formula" for fruit salad. After they interpret the recipe, students use the same strategies to identify chemical formulas. They evaluate the...

Discover the change of the seasons by modeling the Earth-Sun system. Learners model the orbit of the Earth around the sun and explore how and why the patterns of winter and summer occur.

In this color worksheet, students read where light comes from and the different colors created through a prism. Students compare light (additive color) with pigments (subtractive color). Then students complete 1 drawing, 6 matching, 22...

Students write electron configuration of elements using atomic numbers and they identify valence electrons. In this electrons lesson plan, students observe a demonstration showing the space-filling property of an electron. They also...

Ninth graders explore ways water moves through various reservoirs on Earth, examine how human activities change water cycle, investigate substances present in water that indicate human activity, and discuss how understanding water cycle...

Students investigate the world of bees and describe their characteristics. by identifying the bees' parts, they demonstrate how these parts function. In the lab, students dissect bees and view the various parts under microscopes. ...

Students act out different types of circuits, and create their own circuits using wire, a bulb, a battery and a switch.

Students examine concepts of nuclear chemistry. They compare and contrast the topics of nuclear fission and nuclear fision. They predict the outcome of reactions based on the types of emissions and reactants.

Students identify the difference between some physical and chemical properties and compare some physical and chemical changes. They design an experiment to distinguish between a physical or a chemical property of their choice.

In this science activity, students examine how the universe is bound with the atomic particles and focus upon the findings of two historical scientists.

Students experiment to show their knowledge of molecules and atomic structures.  In this chemistry review instructional activity students participate in an activity and then fill out a worksheet.

Students describe the properties of solids and liquids, and explain how a semiconductor works.  In this atom lesson students demonstrate the bonding properties of carbon and silicon.

Students explore the energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students examine the properties of magnets and static electricity. They participate in experiments that demonstrate the behaviors of charged particles, and record their data on a worksheet.

Students cuminate their study of molecular structure and bonding with this activity.

Students practice naming and writing formulas for simple chemicals. After a review of vocabulary, they create ion flash cards and discuss the rules for writing chemical compounds. They practice naming and writing the formulas based on...

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.

Students, after analyzing the history of a concentrator, model how a Genesis spacecraft concentrator works by playing a game. In groups of three or four, after being given materials to work with, are challenged to roll the rubber balls...
