Product Description
About SNAPs Lab Stations Activities
SNAPs Lab Stations Activities require students to use science, math, literacy, problem-solving and engineering skills. They are designed to enhance students' understanding of scientific concepts and help students apply scientific ideas to the real world. Each station activity promotes skills so to develop students into proficient and competent scientific thinkers.

SNAPs lab activities have five components:
Science Skills Station to develop science skill proficiency
Narrative Station to build science literacy
Assessment Station to evaluate learning and understanding
Problem-Solving Station to foster engineering design
Synthesis/Summary Project to inspire higher-order learning

A description of the activities at each station in this particular lab is detailed below.

Next Generation Science Standards
This laboratory satisfies NGSS MS-LS4-3. It combines the three dimensions of science learning - science and engineering practices, disciplinary core ideas and crosscutting concepts - in order to meet the standards. This laboratory also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.

Comparative Embryology Lab Stations Activity Learning Objectives
1. Compare and contrast gross embryological structures and patterns in embryological development of diverse animal groups.
2. Compare and contrast the structures present in an embryo and the fully formed organism.
3. Make predictions about the evolutionary relationship between different species based on their embryological development.
4. Evaluate comparative embryology as evidence that supports evolutionary relationships between diverse species.

Science Skills Station
Students will compare and contrast the embryos of different animals. Students will compare the anatomy of the embryos in very early, mid and late stages of development. They will describe the development or loss of embryological structures in each animal and from this, make predictions about the evolutionary relationship between the animals.

Narrative Station
Students will read about comparative embryology and how it is important to studying evolutionary relationships between organisms, specifically animals.

Assessment Station
At this station, students will answer questions about key terms and ideas relating to comparative embryology. Students will have to employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
Students will evaluate the use of embryology to determine evolutionary relationships between organisms. Students will compare the usefulness of comparative embryology, relative to other forms of evidence, in determining how organisms may have evolved from each other.

Synthesis/Summary Project
Students will have a choice of 11 projects. Suggestions for projects that are best suited for this particular lab are included. It is up to the teacher to control this portion of the lab, and thus, the higher-order skills utilized in this activity. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.
