3. Elephant Toothpaste Demo Time for a Demo!

4. Elephant Toothpaste Demo We mix some concentrated 40% H 2 O 2 (hydrogen peroxide— from the hair salon)… with some dishwashing liquid… with some yeast. And we got water (H 2 O) & a whole bunch of oxygen gas (O 2 )

5. Here’s the elephant toothpaste chemical reaction. We mixed some concentrated 20% H 2 O 2 (hydrogen peroxide—from the hair salon)… with some dishwashing liquid… with some yeast. And we made water (H 2 O) & a whole bunch of oxygen gas (O 2 ) 2H 2 O 2  2H 2 O + O 2 1 REACTANT 2 PRODUCTS

6. Elephant toothpaste chemical reaction. We mixed some concentrated 20% H 2 O 2 (hydrogen peroxide—from the hair salon)… with some dishwashing liquid… with some yeast. And we made water (H 2 O) & a whole bunch of oxygen gas (O 2 ) 2H 2 O 2  2H 2 O + O 2 But what were these for? 1 REACTANT 2 PRODUCTS

7. Elephant toothpaste chemical reaction. We mixed some concentrated 20% H 2 O 2 (hydrogen peroxide—from the hair salon)… with some dishwashing liquid… with some yeast. And we made water (H 2 O) & a whole bunch of oxygen gas (O 2 ) 2H 2 O 2  2H 2 O + O 2 We don’t see these here? 1 REACTANT 2 PRODUCTS

8. The dishwashing liquid & yeast were CATALYSTS! We mixed some concentrated 20% H 2 O 2 (hydrogen peroxide—from the hair salon)… with some dishwashing liquid… with some yeast. And we made water (H 2 O) & a whole bunch of oxygen gas (O 2 ) 2H 2 O 2  2H 2 O + O 2 These were CATALYSTS!

9. CATALYSTS speed up chemical reactions without getting involved! We mixed some concentrated 20% H 2 O 2 (hydrogen peroxide—from the hair salon)… with some dishwashing liquid… with some yeast. And we made water (H 2 O) & a whole bunch of oxygen gas (O 2 ) 2H 2 O 2  2H 2 O + O 2 They helped THIS start. BUT STAYED OUT OF THE REACTION!

10. Blocks 1 and 2 Blocks 1 and 2 Blocks 3 and 4 Blocks 3 and 4

11. ENERGY MAKES THE WORLD GO AROUND! E = MC 2 ENERGY MATTER x (THE SPEED OF LIGHT) 2

12. ENERGY IS MEASURED IN JOULES. Like distance is measured in

13. ENERGY IS MEASURED IN JOULES. Like distance is measured in meters Like mass is measured in

14. ENERGY IS MEASURED IN JOULES. Like distance is measured in meters. Like mass is measured in grams. Like temperature is measured in

15. ENERGY IS MEASURED IN JOULES. Like distance is measured in meters. Like mass is measured in grams. Like temperature is measured in degrees Celsius or Fahrenheit or KELVIN!

16. SO HOW MUCH IS 1 JOULE?

17. SO IMAGINE IF I DROPPED THIS TEXTBOOK ON THE FLOOR & BROKE APART EVERY SINGLE ATOM OF IT! THE ENTIRE BOOK WAS CONVERTED TO ENERGY! NO ASH, NO CINDERS, NOTHING LEFT (MATTER  ENERGY)

18. LET’S BE EINSTEIN! What’s the mass of your textbook (matter)?

19. 2.2 kg 2,200 grams or 2.2 kg (1000 grams = 1 kg) E = MC 2 E = 2.2 x (speed of light) 2 How much energy is stored in your textbook? So how fast is light? Try 300,000,000 m/s.

20. What’s the mass of your textbook (matter)? 2.2 kg 2,200 grams or 2.2 kg (1000 grams = 1 kg) E = MC 2 E = 2.2 x (300,000,000) 2 How fast is light? Try 300,000,000 m/s. So now just roll with your PEMDAS model.

21. What’s the mass of your textbook (matter)? 2.2 kg 2,200 grams or 2.2 kg (1000 grams = 1 kg) E = MC 2 E = 2.2 x (90,000,000,000,000,000) E = 1.98 x 10 17 joules E 2 x 10 17 joules E = 200,000,000,000,000,000 joules! So now just roll with your PEMDAS model.

22. We split a bunch of atoms that day for sure! This was not just a chemical reaction, this was a ATOMIC NUCLEUS reaction. 6.3 x 10 16 joules 6.3 x 10 16 joules CASTLE/BRAVO WAS THE BIGGEST NUKE WE EVER BLEW UP ON EARTH.

23. THAT’S RIGHT, YOUR TEXTBOOK AS ALMOST 3 TIMES THE POTENTIAL ENERGY OF THE BIGGEST NUKE EVER DETONATED ON EARTH. 2 x 10 17 joules 6.3 x 10 16 joules

24. LET’S COMPARE OUR STUFF TO THINGS THAT CAN READILY EXPLODE… Explosive substanceEnergy released in joules Energy of a lightning bolt5 x 10 8 joules or 500,000,000 joules Energy used to bring down WTCs on 9/111.2 x 10 9 joules or 1,200,000,000 joules First atomic bomb dropped on Hiroshima, Japan 6.3 x 10 13 joules or 63,000,000,000,000 joules 10 million gallons of gasoline9 x 10 16 joules or 90,000,000,000,000,000 joules Energy releases from an average hurricane per day 5.2 x 10 19 joules per DAY or 52,013,000,000,000,000,000 joules The BIG BANG that created our UNIVERSE!1.8 x 10 71 joules or 180,000,000,000,000,000,000,000,000,000,000,000,000,0 00,000,000,000,000,000,000,000,000,000,000 joules

25. CONTINUE TO ENERGY! CONTINUE TO ENERGY!

26. EVER HEARD OF A KILOWATT HOUR? IT’S HOW THEY MEASURE ELECTRICITY USE IN YOUR HOME. So a kilowatt hour is equal to 860 calories; or what you get from eating a burger and fries. On a Saturday of sitting inside, you use about 15 Kilowatt hours. (So 15 of those hamburgers and fries) You would have to walk 52 miles to work that ‘energy’ off.

27. WE MEASURE ENERGY IN JOULES THOUGH… There are about 4 joules in every calorie! 6.3 x 10 16 joules 6.3 x 10 16 joules 63,000,000,000,000,000 J 63,000,000,000,000,000 J CASTLE/BRAVO WAS THE BIGGEST NUKE WE EVER BLEW UP ON EARTH.
