Students explain why rain forests have great biodiversity, and list each layer of a rain forest and tell an organism that lives in each. They identify the cause of acid rain and its affect on a rain forest. Students hypothesize the effects of water and sulfuric acid on a leaf and identify the steps of the scientific method.
Demonstrate the importance of eye safety in the science laboratory! Acetone is sprayed on a bare, plastic-wrapped, and plastic-wrapped glasses-clad styrofoam plate to show the importance of protective clothing and eyewear. Phenolphthalein is mixed with sodium hydroxide in a contact lens simulation. Dilute sulfuric acid is dripped on a real pig eye, rinsed in water, and examined for damage to the pupil. This lab requires plenty of preparation time and materials, but the activity is extremely impactful.
Simulated acid rain, a dilute sulfuric acid solution, needs to be prepared for this demonstration. After a condensed lecture on acid rain, you will apply the solution to a sample of granite and a sample of limestone. Your young scientists will create a data table in which to record the pH of the acid rain both before and after passing through the stone samples. The lesson is not exciting, but it effectively shows how limestone can have a buffering effect for the plants and animals.
Demonstrate to your middle school science learners how chalk breaks down in a weak acid. Discuss what affects acidic rain might have on ecosystems. Lab groups then choose one of two questions: "How does acid precipitation affect an aquatic ecosystem?" or "How does acid precipitation affect terrestrial ecosystems?" They work together to design and perform an experiment to answer their question. This is a stellar lesson on acid rain, and it reinforces practice of lab skills and the scientific process.
Aside from a mention of a textbook page, this chemistry assignment is a suitable review of acids and bases. It begins by addressing conjugate pairs and acid base reactions. Neutralization and amphoteric properties are also dealt with. The worksheet concludes with two real-life word problems.
Middle school environmentalists record the pH of four different liquids, including two aerosol cleaning products. They liken the products to acid rain and speculate in writing which might affect the human respiratory system. Although this is a simple lesson, it is valuable in helping learners make connections between the products we use and the impacts on the environment and health. You will find complete background information and a lab sheet provided for your convenience.
Acquaint your chemistry class with acids and bases by showing this bold and bright PowerPoint. Viewers learn about the characteristics of acids and bases and stop at intervals to answer several questions about what they are learning. Use this on the day that you introduce this topic, and follow it with laboratory exercises in which young chemists observe some of these characteristics up close.
Students prepare artificial flavorings and fragrances. In this esters lesson, students combine an acid and an alcohol of choice to make an ester. Water is released and they produce an artificial flavoring or fragrance. They answer 4 questions about the ester they produced.
Three questions, requiring short answers, show that chemistry learners understand the concepts behind balancing chemical equations. Nine equations leave the coefficients to be filled in, and eleven reactions are described for learners to write as balanced equations. This is a comprehensive activity that provides the necessary repetitive practice in balancing chemical equations. This may be useful for a general chemistry course as well as the intended advanced placement course.
A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and organic chemistry. Take a look to see what else this practice exam includes! While this titled as a practice exam, it could be used as an actual exam. Answers are provided.
Students observe demonstrations of exothermic and endothermic reactions and determine the changes that take place in a chemical reaction. Students observe four demonstrations showing entropy, attraction of molecules due to polarity, magnets pulling ions apart, and the effects of CO2 on burning candles. Students experiment with sodium thiosulfate crystals and observe endothermic and exothermic reactions.
