Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

In this chemistry worksheet, students can use the table to observe and name the common types of ions and determine the charges to explain the gain or loss of electrons.

For this chemical reactions worksheet, students are given fourteen chemical reactions that they must write using chemical formulas for the reactants and products. They balance each equation by placing the proper coefficients in front of...

Learners participate in a simulation activity about how disease spreads. They describe how disease spreads and trace a disease to the first infected person.

In these creative hands-on activities, students construct several different molecular models that represent substances that play an essential role in our nutritional needs. Using gum drops and toothpicks, students design the models....

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...

Fourth graders examine the life cycle of a star while listening to Roy Gallent's, When the Sun Dies. They conduct Internet research and recreate a star's life cycle after viewing an animation.

Students develop an understanding of the mole and molar masses of elements. In this mole lesson plan, students use beans to find their relative masses and draw parallels to the atomic masses of elements. Students work in teams and each...

In this solutions worksheet, students solve twelve problems including calculating products made in reactions, determining limiting reagents, calculating molarity of solutions, determining percent composition, and finding volumes and...

In this photosynthesis worksheet, students are given a diagram of photosynthesis and words that correlate with the process. They use the words to fill in the blanks about the process and the structures involved in photosynthesis.

In this galaxies, clusters and planets worksheet, students solve 5 problems including determining sunspot groups on the sun in a particular day, finding the number of individual galaxies present, determining the number of stars in...

For this halogen chemistry worksheet, students complete a practical to gain experience making observations of inorganic halogens and their salts. Students make observations of changes that take place in each chemical reaction and they...

The history of aerodynamics is rich with experimentation and international collaboration. Author Joyce Bryant relays this dynamic past and provides math word problems using the formula of lift, the force that makes airplanes fly. She...

Students will identify the sources and function of carbohydrates and fiber and apply appropriate food preparation techniques.

Students demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during the...

First graders identify the sun as a source of heat and light. They identify features of houses that help keep use sheltered and comfortable throughout daily and seasonal cycles. Students are told that summer is the best season to...

Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic

Middle schoolers distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. ...

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...

In this chemical reactions worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with 34 clues.

In this gas worksheet, learners use the ideal gas law to find volumes of gases, pressure of gases, moles of gases, mass of gases and molecules of gases. They find unknowns at standard temperature and pressure and they calculate the...

In this acids and bases worksheet, students answer eight questions about acids and bases prior to doing a titration lab. They define both acids and bases and explain what a neutralization reaction is as well as a titration.

In this emission spectra worksheet, students use a spectroscope to observe three types of spectra. These include continuous spectrum, emission spectrum and absorption spectrum.

In this catalysts worksheet, learners use transition metals ions to catalyze oxidation reactions of iodide ions. Students measure the rate of the reactions by measuring free iodine as a product.
