Product Description
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 does not address a specific Next Generation Science Standard, but it complements concepts related to other NGSS. This lab combines the three dimensions of science learning - science and engineering practices, disciplinary core ideas and crosscutting concepts. This laboratory also makes interdisciplinary connections to STEM, Math CCSS and ELA CCSS to build the appropriate skills.

Ohm's Law Lab Stations Activity Learning Objectives
1. Calculate total voltage, current and resistance for a series and parallel circuit.
2. Describe the relationship between voltage/resistance/current for a series & parallel circuit.
3. Manipulate Ohm’s Law to calculate voltage, resistance or current.
4. Identify and solve problems that arise when too many electrical devices are added to series and parallel circuit.

Science Skills Station
At this station, students will make calculations. They will use Ohm’s Law to calculate resistance, voltage and current for a circuit as well as an individual electrical device. Students will also employ graphing skills to help them make conclusions about how total resistance changes for a circuit when electrical devices are added to it.

Narrative Station
At this station, students will read an information text about quantitatively studying resistance, voltage and current for a series and parallel circuit. They will learn how these factors change as additional electrical devices are added. They will read a second informational text about Ohm’s Law and how it describe the relationship between resistance, voltage and current for a circuit and individual electrical device.

Assessment Station
At this station, students will answer questions about key terms and ideas relating to Ohm’s Law and voltage, current and resistance. Students will have to employ lower, mid and higher order thinking skills to answer these questions.

Problem-Solving Station
At this station, students will identify problems with adding many electrical devices to a circuit (both parallel and series circuit). Students will come up with solutions to solve the problems. They will evaluate the use of circuit breakers in solving problems associated with adding too many electrical devices to a parallel circuit.

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.
