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...

In this paragraph correction worksheet, students read an 8 line passage. Then students respond to 8 multiple choice questions regarding grammar, punctuation, and spelling errors within the paragraph.

First graders in kindergarten science class discuss matter. They make predictions and then identify mystery items in brown paper bags as either solid, liquid, or gas by using their senses. They discuss that a chemist is a scientist that...

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 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 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 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 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.

High schoolers generate a radioactive decay table for an imaginary element, use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

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 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.

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Students explore a model that illustrates the spread of HIV through an adolescent population. Acting in the role of epidemiologists, students explore the dilemmas of HIV infection presented by a simulation. Students produce a play, skit,...

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...

Young scholars analyze a variety of cooking oils to determine the amount and types of fats included in each.

Students write the electron configuration of elements using the Aufbau principle. In this chemistry lesson, students build their own key that demonstrates the principle.

Students work together to discover the concept of static electricity. They participate in an experiment in which they test different objects charge. They make observations and record them for later use.

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

Students consider the causes of density at a microscopic level. They then discover that one cause of density has to do with how many protons and neutrons the material contains.
