Physical Science is LiT - Connections to Engineering, Technology and Applications of Science

Florida Engineering Education Conference (FEEC)

2. NGSSS Standards:
SC.5.P Investigate and illustrate the fact that the flow of electricity requires a closed circuit. SC.7.N.1.3 – Distinguish between an experiment (which must involve the identification and control of variables) and other forms of scientific investigation and explain that not all scientific knowledge is derived from experimentation.

3. Objective:
Hands-on, minds-on activity that will give the educators an opportunity make connections to engineering, technology and application of science.
5 E model of instruction incorporating technology to address science content.

4. Explicit
I am going to describe and model how to implement the use of a single board, open faced microprocessor to introduce coding.

5. Engage: Pique curiosity and generate interest
What would life be like without electrical energy?
Where does electrical energy come from?

6. What if things start to think for themselves?
Analyze the interactions of science and technology with society including cultural, ethical, economic, political and global factors.
Sensors are adding intelligence to devices address these issues and more.
This surge of technology is creating a vector of change in education.

7. Explore: Encourage student to student interaction
Where does electrical energy come from?
Observe: “Getting Light On”

8. EXPLORATION TIME Design experiment to get light on
Write down steps for getting light on

9. Explain: Encourage students to use their common experiences to develop explanations
Lab Report: Student generate steps to create a circuit using an open faced, single board, microprocessor like Arduino
Materials: 2 wires, cable, LED light, Arduino UNO, breadboard
Experiment / Steps: (include vocabulary resistance, electricity, voltage, circuit)

10. Elaborate: Conceptual connections
Students are now engaged with implementation of their experiment steps to complete a circuit.
Data: Did you get light on? Change one variable at a time and record each change (nature of science)

11. LED Light
Project 1
Wire comes from Arduino 3.3 V to (+) on red line on breadboard
Wire comes out of Arduino GND to (-) blue line on breadboard
Add LED light, short leg goes towards ground, long leg goes next to voltage (3.3V) on red line
Add resistor leg to same row as short leg of LED light
Add second resistor leg to (-) blue row next to ground wire to close the circuit
Plug into computer (power) for electricity.

12. Evaluate: Record Demonstrate understanding of concepts
Conclusion: How did you create the circuit? Where did power come from on the bread board? What was your voltage? What is the resistor for? What would you do next time?

13. Reflection How do you know which evidence to collect during an investigation? Why is it important to identify variables before conducting an experiment (or while evaluating another scientist’s work)? Why is it important that scientists clearly record their procedures? Is another scientist’s work still valid if their hypothesis is disproven? Why or why not? Is another scientist’s work still valid if their results are not replicable? Why or why not?
