STEAM DISTILLATION: Extraction Limonene an Essential Oil from Orange Peels

This is just a classic lab – distillation. However, distillation is often done to separate relatively uninteresting stuff. This lab allows students to separate fragrant essential oils from plants, (in this lab limonene is separated from orange peel however the same techniques can be used to extract fragrances from flowers such as lavender). This is a favorite among students and they can use the essential oils in many ways including in future labs like the soap lab also available. I personally like this lab because it teaches students to make use of something we might normally throw away, the orange peel.

Note: I've done this lab with kids in the 7th grade, although it is designed for high school to college aged students. The main issue is the equipment. If you are a middle school science teacher an have distillation equipment go for it...

A word about ‘Zip Labs’: Horizontal & Vertical Lesson Planning

In general, Zip Labs are science and math activities broken down into ‘horizontal and vertical’ educational increments. By ‘horizontal’ increments I mean each activity can be completed in a minimum of 60 minutes. However, the teacher, and/or student may choose to extend the activity over a longer time period or even days. By ‘vertical’ increments I mean each activity is broken down into segments according to grade and difficulty level. So teachers and/or students can decide where to start and how far to go with the topic.

Each Zip Lab includes potentially much more than any teacher will use at the particular grade level he or she may teach. However, it is my hope that teachers, and students, at lower grade levels will gain valuable insight by looking ahead to see how their teaching/learning will be applied in the future. While teachers and students at higher grade levels can reflect on topics that they should have learned in earlier grades. It is my hope that students see their education as a continuum rather than a series of disconnected and random topics.

Zip Labs include diagrams and illustrations that I hope are appealing to a wide range of ages. However, teachers can choose to omit them if they like. Also included is a Common Core ‘Depth of Knowledge’ (DOK) and grade level range ‘sliding’ indicator to help students visualize the relevance of their work.

New in this activity, optional QPA, (Quality Performance Assessment) ‘Stamps’ for Competency Based grading as well as differentiated lesson planning!

-Depth of Knowledge and Grade Level Slide Indicator Graphics

This unit activity meets or exceeds 21st Century and STEM learning expectations, and Common Core learning outcomes. Note: although ZIP-labs fulfill many CCSS, specific CCS standards are not listed because ZIP-labs are designed to be used over many graded levels so the specific CCSS may be different depending upon these factors. For a list of CCSS in your state please visit- www.corestandards.org

New – Integrated Holistic QPA, (that’s Quality Performance Assessment) created by me! This activity requires NO RUBRICS! The rubric is integrated into the activity itself. Much less work for you and far more meaningful to your students.

Working to change STEM to STEAM.
