Note: To honor the teachers and students represented in the video, please keep in mind the complex nature of teaching, and to be constantly aware that there is much information not available to the video viewer. Thus, it is neither respectful or helpful to jump to large generalizations about the practice viewed. We suggest using a language of tentativeness when discussing video records of practice, and cultivating a stance of questioning and inquiry when analyzing the teaching we observe.

Curriculum: FOSS Mixtures and Solutions Unit
Learning goals:

The science learning goals for the unit were
a) Students will come to know and understand that
• A mixture combines two or more materials that retain their own properties.
• A solution forms when a material dissolves in a liquid (solvent) and cannot be retrieved with a filter.
• Evaporation can separate a liquid from a solid in a solution.
• The solid material separated by evaporation from a solution forms distinctive patterns
b) Students will develop scientific thinking skills to conduct investigations and build explanations, and develop science process skills such as observing, communicating, comparing, organizing, and relating.

The language and literacy learning goals for the unit were:
1. Students will be able to communicate effectively, orally and in writing, with classmates and the teacher about the study of mixtures.
2. Students will be able to use science and academic vocabulary, and transition words to develop and write a coherent action plan to separate a mixture.
3. Students will be able to analyze and revise their written plan for separating the mixture, and recount orally and in writing what happened in the lab.

a. The total lesson time was 1 hr 40 minutes.

c. The FOSS science curriculum and kits are used in this school and district.
