6. Defining STEM
Science – Science seeks to explain. Scientists write explanations based on evidence to explain the natural world.
Technology – Technology is a tool that improves and extends our ability -- in research, measurement, accuracy and collaboration.
Engineering – Designs solutions to solve problems using the explanations of science, the language of math, and the tool of technology. It is innovative and creative.
Math – Math is a language used to problem solve and explain numerically how the natural world works.
W = F x D
Have them record in their journal their own definition of STEM and why we should integrate technology in our science classrooms.

11. Icebreaker Engineering Design Process: EDP Card Game
Using the package of cards given to you, have one team member shuffle and deal the cards.
One designated player will begin by placing one of the cards on the table. Look at your cards and choose the one that comes first.
Each of the next players will do the same, but will begin to organize the cards in the order that the team decides the design process should follow.
Discuss with your team and defend your Claim with Evidence for the card’s EDP position on the table.
Be creative and do not think only of a linear process.
One stays the others stray

13. Determining the Densities of Different Metals
Work in teams of 3-4 members
Consider all ideas brought forth by team members
Problem: How to effectively determine the density of various metals using electronic balances and graduated cylinders
Criteria: Each team will produce density data which will be matched to published densities provided by the teacher
Constraints: Quality of instruments and time
Goal: To match the team’s data collected to real data with minimal errors

15. Beanium Lab: Determining the Average Atomic Mass of an Element
Work in teams of 3-4 members
Consider all ideas brought forth by team members
Problem: After reviewing the process where average atomic masses are calculated, students will measure the average mass and percent abundance of the 3 isotopes of a new element recently discovered (Beanium).
Criteria: Using only the materials given, students will be evaluated to determine if their measured average atomic mass matches the predetermined established value.
Constraints: Only the materials given can be used.
Goal: To determine the average atomic mass of Beanium and compare the mass to other groups.

16. Making and Naming New Ionic Compounds
This activity requires to work by yourself
Problem: After reviewing the concept of balancing the charges of positive and negative species in ionic compounds, students will create as many different unique ionic compounds as possible in the time frame allowed.
Criteria: Using only the materials given, students will be evaluated to determine if they can create and name as many unique, correctly balanced, and different ionic compounds as possible.
Constraints: Only the materials given can be used, and limited time.
Goal: To create and name as many different unique ionic compounds as they can.

19. Reflections What? What did you do? So What?
When thinking about incorporating a STEM-Centered Classroom into your science classroom how would you easily include this day’s activities?
Why should STEM be brought into your science classroom?
Now What?
How will you make sure there is alignment of content?
