Topic: Adapting the Science  Curriculum

I read the article “Interactive Word Walls: Transforming Content Vocabulary Instruction” by Julie Jackson, Sherry Tripp, and Kimberly Cox. This article discusses how word walls can be interactive for students to learn science vocabulary terms. Students are often given vocabulary words that they need to define for a science unit. Writing down definitions is just memorization for students. Students need to make connections with vocabulary words in order to retain them. Interactive word walls include pictures of vocabulary terms to illustrate the meaning and deepen students’ understanding (Jackson, Tripp, & Cox, 2011).  Having pictures of vocabulary words will especially help English Language Learners learn the content. Pictures are easier for ELLs to understand rather than definitions.

 Jackson et al. (2011) mentioned that student participation with the word wall supports literacy and learning for all. Teachers can let students draw pictures of the vocabulary words and write the definitions in their own words. Allowing students to write definitions in their own words makes it easier to remember the terms because the words are put in everyday language. Science definitions often have long, difficult words that sometimes make it hard for students to understand. Interactive word walls makes learning new vocabulary words fun for students. Having pictures of vocabulary terms helps students make connections, rather than copying definitions from a textbook.

Topic: Lab Safety 

I read the article “Scope on Safety: Safety is always in fashion” by Ken Roy. This article discusses appropriate lab attire. Having protective clothing in the lab is very important. The first section is about clothing. No loose clothing is allowed in the lab. Loose clothing includes jackets, coats, hats, or any other overhanging articles. Roy (2008) states that the rule of thumb for clothing is for clothing to cover the body from the neck to at least the knees. Having a lab apron over clothing adds extra protection in the case of splashed chemicals. Covering your eyes and feet are important for working in the lab. Goggles should be worn at all times because chemicals used in the lab may damage your eyesight. Open-toed shoes such as sandals and flip-flops are not allowed in the lab. Closed- toe shoes such as tennis shoes or sneakers can be worn in the lab. 

Roy (2008) mentions that students will long hair will need to pull their hair back when working in the lab. Having long hair is dangerous in the lab especially when working with any heating sources and equipment. Gloves offer hand protection. Some chemicals in the lab can damage the skin so wearing gloves are required. Latex and vinyl gloves can be used. For students with a latex allergy, the teacher can have latex free gloves for them to use in the lab. Teachers need to set a list of rules about attire to be worn in the lab. The list of rules can be in a lab safety contract that the teacher sends home during the first weeks of school. Both the student and parents should sign the contract acknowledging that they have read and understand the rules. Lab safety is important for students to abide by so science experiments can be fun for all students.
