Students identify and observe chemical changes. In this chemical reaction lesson, students use various substances to observe the characteristics of a chemical change. This lesson has three activities including an experiment with baking soda and vinegar.
In this triboluminescence worksheet, students use wint-o-green Lifesavers to observe a chemical reaction that gives off light. They break a lifesaver up with a hammer and make observations and they chew a lifesaver and make observations. Students record their observations and answer questions about the chemical reaction that took place.
In this chemical reactions activity, students complete a crossword puzzle by figuring out the vocabulary words associated with 34 clues.
Students perform a chemical reaction experiment. In this chemical reaction lesson, students mix familiar chemicals together to make polymer. Students decide if they made a liquid or a solid. Students then research polymer and share the information with the class.
Students, in groups, combine given materials from an everyday kitchen until a chemical reaction occurs and record the reaction time.
First graders explore chemical reactions in hot bottled soda and cold bottled soda. In this lesson about chemical reactions, 1st graders observe an experiment and discuss the results as a class. Students determine why bubbles are evidence of a chemical reaction. Students answer four questions as an assessment.
In this chemical equations learning exercise, students write the symbols for the products and reactants and then write balanced symbol equations for the 20 chemical reactions given.
Fifth graders experiment with biodegradable materials. For this science lesson, 5th graders perform a series of experiments, then discuss and chart their observations. Through the experiments, students will be able to identify three types of biodegradable materials.
Students examine transitional metals. In this chemical reaction instructional activity, students investigate the transitional metals used in coins. They will observe some of the chemical properties of these metals and discuss why coins are made from transitional metals.
Students perform a series of experiments on copper to produce a variety of copper compounds. In this chemical reactions of copper lesson plan, students use copper wire and nitric acid to produce copper nitrate. They then form a hydroxide followed by an oxide and they regenerate the initial copper. They answer 3 questions about the experiment.
In this alchemy worksheet, learners read about the early thoughts of alchemists regarding elements. Students are given an experiment done by an alchemist during the Middle Ages and they answer three questions about the experiment knowing about evidence of chemical reactions.
In this writing equations worksheet, students are given 6 chemical reactions and they write equations for each one including the reactants, the products and the states of matter.
Learners explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Learners will collect and summarize data and create a class presentation. This lesson is hands on and includes multiple web links.
Students design and perform simple inquiry investigations in order to answer a question posed by the instructor. They combine specific amounts of sodium bicarbonate, calcium chloride, and phenol red in a closed zip lock bag system.
In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In addition, they answer questions about elements and compounds and identify reactions as chemical or physical changes.
Students recognize the production of a precipitate. In this chemical reaction lesson, students read aloud and then perform a lab activity showing the reactivity among different metals as a replacement reactions.
Students investigate why an apple turns brown after being cut open and brainstorm why this occurs.  In this oxidation instructional activity students design and conduct a simple experiment, analyze their results and draw conclusions. 
Students explore endothermic and exothermic reactions. In this chemistry lesson, students differentiate between endothermic and exothermic reactions using an EasyTemp probe. They plug the probe into the TI collecting vital data.
A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50 multiple choice question by topic, as the questions alternate between the two. The problem-solving section could stand alone as a chemistry quiz, but the third section has both chemistry and biology essay questions. Perhaps you could use this as a resource for questions that you could incorporate into your own test.
In this enthalpy equation worksheet, students are given 3 examples of chemical reactions. Students then respond to 4 practice problems and 1 challenge problem in regard to heat and energy change and release.
