30 Minutes    Hands-on Learning Activity: Balloon Supernova 

                     Materials:  Large balloons, punched from different colored construction paper, paper plates, wall tacks, broom 

                     Procedure: 1. place the paper punch outs in the balloon and inflate it. 

                                        2. Tie off the balloon

                                        3. Shake the balloon about and watch the "atoms" move about furiously 

                                        4. Pop the balloons 

                                        5. Sweep up the pieces and place them in the paper plate                             

                       What did you learn from this activity?

                       Why are some ‘elements’ more rare than others?

                       What causes a star to explode?

                       What happens when a star explodes?


60 Minutes    Videos and reflection questions

             Supernova

What are you made of?

What two forces must be in balance to keep a star shining?               

            Elements, atoms and electrons 

What is an element?

Who created the periodic table we use today?            

 Accretion

 How was the earth formed?

            Mining

 How are elements extracted from the earth?

            Refining,

                        What are some ways metals are refined?

            Shaping

                        How is steel turned from ingots into sheets?

            Forming

                      What is a stamping die?  What part’s of Photon where made with this

process?


60 Minutes      Additional questions: 

1.     How do metal products get to your house after they have gone though the stamping process?  Do some research and then list all of the steps.

2.    How is plastic made? 

3.    What does the word “plastic” mean?

4.    What is one very important way most plastics are different from copper?

5.    Can you think of one way this day one unit is preparing you for building Photon?


Key Terms 

Stars

Fusion is the process by which energy is released and elements are formed in stars

Fusion

Fusion is the combining of light nuclei to form heavier elements and that it produces a lot of energy which we experience visible light and radiation

Gravity

Gravity Is a force that attracts objects that have mass - the greater the force the greater the mass

Elements

Elements are building blocks of matter organized by the number of protons in their nucleus. Understand protons are positively charged, neutrons are neutral and electrons are negatively charged

Iron

Stars cannot fuse the element iron so they run out of fusion energy allowing gravity to cause the star to collapse and explode

Supernova

Not all stars become supernovas, but the ones that do are some of the brightest things in the universe. When a star collapses during a supernova event the extreme forces allow it to create elements heavier than iron like gold

Accretion

Gravity causes the bits of exploded stars to combine over millions of years forming a planet like earth

Mining

A mine is a place where ores are extracted from the earths crust

Refining

Elements must be refined from ore though various processes depending on the element being mined

Forming/Stamping

Most metallic elements can be shaped and drawn through mechanical processes

Assembly

Most products we use are put together on assembly lines

Packaging

Packages protect and advertise our products

Shipping

Products we use are shipped around the world in boats, planes, trains and trucks

Shelving

Products we use are stored in stores until we buy them

Atom

An atom is the smallest part of matter that cannot be subdivided using mechanical or chemical means

Proton

A proton is a positively charged particle at the center or nucleus of an atom

Neutron

The Neutron is a particle with no charge at the center or nucleus of an atom

Electron

An electron is a negatively charged particle that exists in orbit around the nucleus.
