Incorporating STEM and Academics in Agricultural Education
How a Change of Curriculum Makes a Difference/Using CASE at the Introductory Course LevelSlide2
Why be concerned about STEM?
Not the latest educational fad
Demand for STEM-based education is coming from industry to colleges to secondary education
Adoption of Common Core standards means meeting standards across the traditional disciplines
New teacher evaluations mean ALL teachers are responsible for students’ test scores
STEM can be easily incorporated into CTE – especially Ag Ed
Ag Ed must continue to be part of the solution in education, not perceived as a problem!Slide3
CASE is a tool for incorporating STEM
Concept-based, not content-based
Infusion of STEM throughout curricula
Formulated along Learning Focused methods
Students find the depth of material in the lessons – the instructor is a coach
Use of collaborative groups – modeling industry
Organization of a notebook – later courses create a lab notebook – again modeling industry
Classroom now matches FFA Chapter – students lead themselvesSlide4
Why is the notebook a big deal?
An industry standard
A STEM necessity
Professional training
Builds as students move to higher courses
Lab reports build as students move to higher courses – eventually separate notebookSlide5
Activity 3.2.2 – Life, Death, and pH
Lesson 3.2 – Principles of pH
Preface
The pH of substances is a measure of acidity or alkalinity. pH is important to the health and well-being of living organisms and is involved in many chemical processes. Nutrient uptake and absorption in plants and animals are influenced by the acidity or alkalinity of soil, water, and feed. pH indicators for acids and bases are also used to collect qualitative data in many experiments, thus an understanding of pH is important for students in Agriscience.
This lesson will introduce students to the basics of pH through the testing of common substances. Students will also conduct a structured inquiry experiment and write a lab report.
Concepts
1. The level of pH is used to determine the acidity and alkalinity of a substance.
2. The pH scale is 0-14 where 0 is extremely acidic, 7 is neutral, and 14 is extremely basic.
3. The level of pH affects the health and well-being of organisms.
Performance Objectives
It is expected that students will
· Determine if a substance is an acid or a base using

and a pH sensor.
· Test the buffering ability of water and one additional substance.
· Conduct an inquiry lab on the effect of pH on plant health.
· Write a lab report based on findings of the inquiry lab
