Reaction Time vs Reflex Time

In this post activity to the school program, Neuroscience, students will learn the difference between reaction and reflex neural pathways. They will simulate what happens in their body during a reaction and during a reflex to better understand why there is a difference between the two.

Programmable Hydraulic System

For this lesson students will build a hydraulic system using syringes filled with water to demonstrate Pascal’s principle. This system will be controlled using an Arduino, bread board, and DC motor. Students will need to also be familiar with simple circuits, electrical terms, and components when completing this activity. The code needed for this project is quite simple. I recommend taking one class to familiarize students with the basics of the code and how the Arduino works by having them configure a simple circuit and play with some code to make some LEDs change and blink. Once familiar with the code basics, the code to control the DC motor and make it go forward and backwards, along with a circuit diagram, may be provided to the students depending on what the goals for the students may be.

Are you Eating Nails for Breakfast?

Students will carry out a laboratory experiment to isolate particles of iron in their breakfast cereal. They will then identify other variables that they would like to test for and using their Smarter Steps to Inquiry framework, go ahead and test their variable. Lastly, a class discussion would take place discussing the difference between chemical and nutritional iron and the need for iron in our bodies. Students should also be prepared to discuss the other variables that they tested for and their results.
