In this periods, groups, valence electrons and masses activity, 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 electrons...

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...

Students study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Students also graph the data they collect and...

Students investigate Nanotechnology. In this physic's lesson, students evaluate a hands-on model made from chocolate syrup and pretzels to determine the advantages of size.  Students weigh chocolate syrup to determine it's wait...

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.

Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

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...

Young scholars 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....

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 generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

Using the chemicals that leaked in the Bhopal gas tragedy of 1984, chemists examine covalent bonds. Provide for them the chemical reactions and have them draw Lewis diagrams for the molecules involved. That's about all there is to the...

Learners write the electron configuration of elements in the ground state. In this chemistry activity, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

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

Learners 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 examine the structure of molecules, their formula, and percentage composition of each element in the compound. They construct an organic compound with different functional groups using a modeling kit, and draw a 3-D structure...

Students investigate the dangers of radiation by exploring recent nuclear tragedies.  In this scientific debate lesson, students define the idea of radiation "half life" and determine if low doses of radiation are truly damaging to...

Students list reasons why water is important and investigate and graph the freezing points of different solutions.

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.

Young scholars investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps...

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

Students conduct lab test with minced onion to determine where chromosonal DNA is located within the cell, and whether or not it can be extracted.

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

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