Ninth graders investigate acids and bases. In this pH lesson, 9th graders test, observe, and discuss natural acids, bases and the pH scale. Students will construct a KLH chart and then use litmus paper to test an acid, base, and water. This lesson includes instructional tips, differentiated instruction, several extensions, and necessary attachments.
Fourth graders compare the color of cabbage water when acids and bases are mixed in. In this acids and bases lesson plan, 4th graders use cabbage water and mix in acids and bases that the teacher prepares before hand. They observe the color change and compare it to the ph scale associating it with and acid or a base. They fill in a color, acids, and bases sheet for assessment.
What is pH and how is it measured? What happens when acids and bases mix? In an extensive 5E experiment and instructional activity, young chemists create their own pH paper, test the pH levels of several substances, evaluate their results, develop and perform their own experiment, and share with the class. Note: In order to perform this lab, you will need a juicer, so if you do not have one, you will need to borrow one.
Did you know that driving 2,500 miles results in an entire ton of carbon emissions added to the atmosphere? This tidbit and others on how carbon dioxide is also increasing in ocean water are the focus of a powerful lesson plan. Participants are introduced to ocean acidification with a video, and then they carry out two investigations that will reveal the increasing pH of the world's oceans. This is a poignant lesson plan, perfect for encouraging youth to become environmentally aware citizens.
Don't you wish you had the time to type up a study guide for your chemistry class? With this resource, there is no need! A chart comparing the properties of metals and non-metals tops the handout, followed by notes on the reactivity series. Finally, you will find an overview of fossil fuels. Use this as an outline for your lecture or to give a copy to junior chemists as notes or a study guide.
Testing the pH levels of household products and then experimenting with acids and bases sounds like the start of a great afternoon. Children discuss the properties of acids, how they taste, and what acids do. Then, they conduct several simple experiments where they see the powers of acids firsthand. They dissolve a penny, create a cabbage indicator, and see how bases neutralize acids. Full experiment procedures, background information, helpful websites, and a worksheet are all included.
