A fun read that exposes students to the concept of acids and bases. Two levels (approaching & on grade) are providing to meet the needs of your students. Like all our text, is is written according to the recommendation of Common Core for complex text. This article would be great for a close read to support inquiry science. If you are friends with the ELA teachers on your team you might even convince them to use this text and get some real integration going between ELA and science. Comes complete with ELA-style questions. Supports the Science Standard: Florida NGSSS: SC.8.P.8.8 Identify basic examples of and compare and classify the properties of compounds, including acids, bases, and salts. NGSS: MS-PS1-5 TEKS 6.5 Matter and energy. The student knows the differences between elements and compounds. The student is expected to: (A) know that an element is a pure substance represented by a chemical symbol and that a compound is a pure substance represented by a chemical formula. Readability: All of our text is checked with multiple metrics to assure it is at an appropriate complexity for the student. By using multiple metrics, our experienced and knowledge staff are better able to determine an appropriate grade level rating. In most cases (we are still working on updating all text), you will see our text marked as Approaching, On-Grade, or Advanced per a specific grade. We are also careful to create text with an appropriate length using a well-established norm (Grade Level x 100 + 100/300 words). We do this so our text to be used not just in the science classroom to support content, but also to be used in a reading classroom to support the development of strong readers. All of our text comes with at least 5 ELA-style questions for this purpose. About Us: Candlelight Science is a group of educator/writers. All have been (most still are) traditional classroom teachers with an average of 20 years of experience. We started our work because of a local need, but quickly realized the need for high quality, inexpensive resources was great. In response, we continue to produce science readers with multiple reading levels (compatible with CCSS text-complexity requirements), lesson plans, and even assessments to make the lives of teachers easier and more productive.
