Discuss the language demands included in the lesson on mixing substances in a 5th-grade classroom by Identifying key vocabulary terms students must know in order to master the learning objectives for the lesson based on the below standard and learning objective. Standard Conduct an investigation to determine whether the mixing of two or more substances results in new substances. Learning Objective Given a variety of substances and safety equipment in a classroom setting, students will be able to conduct an experiment to mix two or more substances and observe the results. They will be able to correctly identify whether a new substance has been formed as a result of the mixing, based on observable changes such as color change, formation of a precipitate, or change in temperature, with at least 80% accuracy.
