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-LS4-6 and supplements MS-LS4-4. It combines the three dimensions of science learning - science and engineering practices, disciplinary core ideas and crosscutting concepts - in order to meet the standard. This laboratory also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.
Natural Selection Lab Stations Activity Learning Objectives
1. Discuss the theory of evolution by natural selection.
2. Describe how the frequency of traits in a population changes due to natural selection.
3. Conduct an investigation to simulate competition for resources and the process of natural selection.
4. Analyze and interpret data in tablesand graphs to support explanations of natural selection and changes of traits in a population over time.
5. Apply concepts relating to adaptations and natural selection so to design, build and test a tool that allowsforsurvival and reproduction.
Science Skills Station
Students will conduct an investigation to study how adaptations improve the ability of some individuals to compete, survive and reproduce while suppressing others’ ability to compete, survive and reproduce. Students will compete with each other for food using a feeding tool. They will interpret and analyze data to determine which tool is the best and worst adapted for feeding.
Students will read a passage about Charles Darwin and the tenants of this theory of evolution by natural selection. Students will also watch a video about common myths and misconceptions about evolution.
At this station, students will answer questions about key terms and ideas relating to natural selection. Students will have to employ lower, mid and higher order thinking skills to answer these questions.
Students will design, build and test a device that mimics a beak and is able to feed on a wide range of food items. Students will be provided with materials from which to construct the feeding device. Students will test the device on several different food items to see how well it eats different kinds of food.
Students will have a choice of 11 projects. Refer to the SNAPs Lab Stations Best Practices and Setup Guide for directions and suggestions on how to conduct the project.
