Process & Products
Concept/ Theme/ Issue
Advanced Content
PROCESSES Scientific Method Engineering Design Problem Solving Models Analysis
BIG IDEAS WITHIN & ACROSS FIELDS - Systems, Cause and Effect, Order & Chaos - Applied in Meaningful Ways
CONTENT Biology, Chemistry,
Engineering, Physics, etc.
ADVANCED CONTENT
Pre-assess to measure student knowledge of content Delivered at a level of depth and pace appropriate for learners Centered around a concept(s)
HIGH LEVEL PROCESSES
Ask questions to check for student understanding of content and to challenge thinking Design learning tasks related to content and to measure how students are mastering and manipulating content & concepts
Connected CHALLENGING PRODUCTS
Post-assess Students show mastery of advanced content and scholarly thinking. Concept(s) represented Repeat process with new content and learning goals

Overarching Concepts are Particularly Applicable to STEM
Order and Chaos Example
Atomic Theory, Physics Unexpected results from an experiment
Systems
Example : Biology All about systems from the cell to the human body, ecosystems, etc. Parts of brain working together for complex thinking/activities
Cause and Effect
Example: Chemistry If I mix these two chemicals together what happens? Making Observations and seeing changes occur if you slightly change something Patterns, Exploration, Power, Structure
Others include Patterns, Exploration, Power, Structure

Advanced Content
Either you are an expert already or you can become pretty knowledgeable with the right resources
Find a Scientist or Engineer at local university or college with a passion for outreach or with outreach programs

The Scientific Method Processes
Choose your topic
Identify a Problem
Research the Problem
(Background)
Develop a Hypothesis
Design experiments to Test Hypothesis
(Methods)
Do the Experiments
(Results)
Analyze the Results
(Conclusions)
Both Scientific Method and Engineering Design are
action plans for problem solving and critical
thinking!

My Personal Experience Using the Integrated Curriculum Model
Marvelous Molecules Course designed around chemistry concepts
OverArching Theme Cause and Effect Advanced Content - Atomic Theory, Matter, Chemical Equations and Reactions Product/Process Hands on Labs, Inquiry based, Scientific meeting/poster presentation
Brain Blast Course designed about neuroscience concepts
Overarching Theme - Systems Advanced Content: Brain anatomy, neurons, function, neuronal circuitry, brain and the body, neurodegeneration Product/Process Hands on labs, Inquiry based, scientific meeting/poster presentation
Practicing ICM
Classes Students choose their own topic related to class to further explore Test their hypothesis with experiments they design Present in a scientific meeting via poster presentation
Examples: - Cerebellum - Fine motor control comparison between male/female, long term memory techniques - DNA extraction method enhanced by my 1st/2nd grade students - Mentos/ Coke Experiment Comparing different substances and
modifying it to a small scale experiment (Less messy!)

Is smell sufficient to determine what something is?
Lets Try It Out With A Mini Lesson/ Experiment
How can I add advanced content to this lab? What about critical thinking or problem solving components? If letting students choose a topic and further experiments, what ideas could they explore or do with this new knowledge? How could I use this lab with my students?

Instructions Students work in pairs. 1. Hold the bag upright over the plate while the other student adds the 15 mL of phenol red solution to the bag. 2. Seal the bag and keep it upright. 3. Feel the bag, and record observations. 4. The teacher adds a spoonful of anhydrous calcium chloride. 5. Seal the bag as quickly as possible after the calcium chloride is added. 6. Keep the bag upright and sealed while gently shaking the bag back and forth to mix the contents. 7. Observe what happens after the calcium chloride was added . The reaction takes about three to five minutes. During this time the student not holding the bag should write down any observations that the pair has made.
My observations showed a temperature change, changes in pH, and the formation of a gas. What components were responsible for which observation?
What caused the heat? Why did my pH change? How did that chemical reaction form a gas?
By mixing these chemicals, I get a temperature change, an acid to form, and made the bag expand. How can I use this chemical reaction?
Can I harness the heat to keep something warm? Can the gas be collected and used to make something expand? Can the acid be used to clean a penny?
Chemical Equations
(1) The bicarbonate ion (HCO3-) is a weak acid and partially ionizes in solution.
HCO3
- (aq) H+ (aq) + CO3 2- (aq)
(2) Calcium ion (Ca2+) from calcium chloride reacts with sodium bicarbonate to give insoluble calcium carbonate.
Ca2+ (aq) + CO3 2- (aq) CaCO3 (s)
(3) The removal of the carbonate ion from solution shifts the bicarbonate equilibrium (1) to the right, releasing more H+, which reacts with more HCO3
- to produce CO2 gas and H2O.
H+ (aq) + HCO3- (aq) CO2 (g) + H2O (l)
(4) The indicator changes color because the carbon dioxide dissolves in water to produce an acidic solution.
CO2 (g) + H2O (l) H2CO3- (aq) H+ (aq) + HCO3
- (aq)
