Leif - Dark matter:Shared how this is still based in theories but many varying theories. It was first discovered by Jan Oort in 1932. Dark matter is thought to make up over 80% of the universe and the mass within. It is hard to observe as it does not emit or absorb light or other electromagnetic radiation. Leif also shared a picture of dark matter. Luke - Quark gluon plasma: explained what a quark is and what a gluon is and what they do, shared what a proton, neutron and neutrino's are and their size and quark make up. Shared how the Quark Gluon state is reached. Ayden - Colour glass condensate: explained how this is always present in matter but only visible at the certain state. Explained about quarks and gluons as well and how the CGC interacts at different phases. Shared how Einstein first theorized this but it wasn't until 2012 that it was first seen. Liam - Magnetically ordered: shared the spectrum of magnetic states, only one is visible to us on earth. Shared the properties. Zander - Superglass: Zander shared that this state is a proposed state buy yet to be confirmed with observation (although they are observing one reaction currently that they believe is this state). In this state you have a state where there is a frozen amorphous solid (like glass) that is superfluid at the same time. Zander shared that some people think as glass as a fluid, some a solid and some as a state of it's own. He shared the following videos: Discussed glass, the technology of google glass, where that may evolve to, how it may be improved upon. We talked about how in 10 years which things will seem ancient. We talked about research and discovery. The kids picked another Through the Wormhole to watch for the list http://en.wikipedia.org/wiki/Through_the_Wormhole We looked through the list of Famous Scientists to choose a scientist to research and share for next class.
http://www.famousscientists.org/ Leif - ALbert Einstein Luke - Archimedes Ayden - Richard Dawkins Liam - Thomas Edison Zander - Nikola Tesla Assignment due May 3rd: Research your favourite scientist/inventor and share about his life and findings to the class next week. (Look for what topics of science did they explore, how many attempts did they make, were they entirely right, what was their life like, who were their mentors, what we the world be like without them, what did they give us, what findings have come since that have built on their findings) You can bring in an experiment to demonstrate, something he/she invented, some pictures to pass around. Next week Science Party! Bring an item for the feast maybe something science based... lots of kitchen chemistry you could talk about and share.

Share Assignments Ayden - 4D donut shaped universe from top view Taro - 4D cube called the Tesseract or Hypercube Zander - 4D donut shaped universe that we are on the surface of. Leif - shared 2 thoughts, inside 4D cylinder or inside 4D donut. Liam - spiraled universe like our galaxy. Luke - ever expanding sphere for universe. Watch Through the Wormhole; In the Beginning Key Points Big Bang/Inflation theory vs Inflate and Contract theory vs Brane Theory -covered the accepted Big bang theory and the idea of singularity (the Universe started from one point and before that was nothing. In an explosion the Universe expanded and later cooled creaing matter, galaxies and stars. It is forever expanding.) -although still along the lines of singularity, the Universe expands and then contracts, expands and contracts. -going into 11 dimensions we stretch our minds to think of the branes (like membranes), parallel 4 D worlds separated by a small distance with a weak attracting force between that causes occasional collisions between branes, creating the energy/bangs and expanding out the universe until it cools or is stretched by the ever present dark matter to a flat state again where another bang will happen. Discussed Chapter 10 of the Story of Science, Getting Atom. Learned about Democritus(ca 460BCE) and his theory of the atom, the smallest part of all things, he named it atom meaning uncuttable. We talked about the parts of an atom, what quantum science is starting to discover, even smaller parts (quarks, strings etc) Watch Bill Nye and Discussed Empty space. States of Matter; what is happening to the atoms? Talked about the 3 states of matter that we commonly see naturally occurring on Earth. We also talked about the Plasma state, the 4th state of matter. We talked about the existence of many 'exotic' or 'non classical' states of matter that exist as well. http://en.wikipedia.org/wiki/State_of_matter We did a demonstration to show plasma. 1. slice a grape lengthwise down the centre almost cutting it in half but keeping the it just enough intact so it opens but is still together. 2. place on a plate and put in microwave for 12 seconds. 3. watch plasma appear! Discussed what is happening to get to the plasma state (release of electrons through an ionized state. shows like a zap of electricity) Assignment due April 26th Research an 'Exotic' State of Matter (not solid, liquid, gas or plasma). Make a diagram, a model, or share an experiment for the class. Leif - Dark matter Zander - Superglass Luke - Quark gluon plasma Ayden - Colour glass condensate Taro - Strange matter Liam - Magnetically ordered Optional Assignment Watch Through the Wormhole: Are there more than 3 Dimensions / Through the Wormhole: Beyond the Darkness Share Assignments. Leif shared his using of Thales ratios to measure the height of his house. Luke shared his range of objects he tested with his electroscope. Zander shared his chart with objects he tested with his electroscope and their readings. Read chapter 5 Story of Science; The 'A' Team Anaximander: Student of Thales. Earth is curved, life started in the water, humans came from mermen, the moon is made of its own matter, it has mountains, the moon inhabited by life. Sphere of air around Earth that holds the Sun and Moon. Earth unsupported and is just suspended. Anaximenes: Student of Anaximenes. Everything is from water. Earth is flat, Mars and Venus not stars, rainbow a natural phenomenon not from a Goddess. Anaxagoras: Other inhabited worlds, moon shines the reflection not it's own light, the Sun is a fiery stone the size of Greece (persucuted and jailed for this idea!) He said 'Reason rules the world.' List what they discovered. What were they right about, what were they wrong about? What other things have been wrong? Is Science dangerous? For who, why or why not? What do we know about space? Our solar system? Our galaxy? Our universe? How do we know? Discuss how telescopes work. Watch: Key Points: Galileo did not invent the telescope, It seems to be a optician Hans Lippershey. Lippershey invented the spyglass using the same principles of a telescope to see far away objects. Galileo heard of this and rebuilt a model to see the heavens. The timeline of the findings of the orbit of the planet, the stars, the moons, and all the way to the discovery of Uranus. Discuss the shape of the universe? What do you think it is? What is the 4th dimension? Key Points:
1st DImension - 2 points 2nd Dimension - 4 points 3rd Dimension - 8 points 4th Dimension - 16 points Sculpture of 4th Dimensional interpretation in France. Measuring Math Brain (stimulus happening in part of brain when concentrating of numbers Math is a language Math describes the natural world Prime numbers (only divisible by themselves and 1) Theorized shape of universe and why. A cylinder side to side and a cylinder up and down, wrapping int on itself (a donut shape) We are on the surface of this donut shape. Must be in a 4th dimensional universe?? Assignment due April 12th 1. Draw, sculpt or model what you think the universe looks like. Explain why you think that (there are NO wrong answers) AND?OR 2. Draw, sculpt or model what you think an object would look like in the 4th dimension? (a square has 8 points in 3rd dimension and must then have 16 in the 4th) Optional Assignment Make your own telescope Sharing Assignments Ayden shared his findings on the Pulsar clock (accurate to many decimal places and use the frequencies sent by pulsar stars. He also shared the Korean calendar which is centred around kim Lee, the year of his birth 1912 starts their calendar. Zander shared the Ball clock passing around a picture and explaining how it worked. Liam shared the Salish calendar, the 12-13 lunar cycle of the year and the names of each month. Leif shared the Buddhist Calendar, the names of the months, the benefits and faults. Taro shared the Egyptian calendar, names of months, benefits. Luke shared the Astronomical clock. He showcased the pictures he took when he visited it personally and explained all the meanings of the symbols and figures and how it works. Very interesting! Here is a link to the 600th anniversary show of the Prague Astronomical clock http://www.youtube.com/watch?v=QjWJHEmFfPA Read Ch 4 Story of Science On Map look for Ionia Mediterranean Sea Aegean Sea Athens Turkey Talked about Thales, father of science, what professions, what known for? Thales and Static Electricity - transfer of electrons Protons, Neutron and Electrons Watched Bill Nye Discover Static Electricity Stations Magnetic Cereal? What's happening? Bending Water - what's happening? Make an electroscope. Thales Ratios Discuss and head outside to demonstrate. Walked to park to measure flagpole (height from ground). First going 10 paces out (about 1 m per pace) we angled our sticks so the top pointed to the top of the flagpole. We then took that stick to be 1 pace away and measured with our measuring tape the height to where the stick points to a 1 pace away. We then drew the triangles to see the ratio (one large triangle 10 paces long and flagpole high with our stick angle, the second 1 pace long and 1.35 meters high with our stick angle. That means that the height is 10 times that of the small triangle.... 13.5 m. Way to go! http://www.sciencemadesimple.com/static.html http://www.exploratorium.edu/science_explorer/sparker.html http://www.sciencebob.com/experiments/staticroll.php Assignment:
1. Test some household objects with your electroscope. First you can try charging items by rubbing them to see which items will lose and gain electrons. (You can rub different items against a plastic comb) Then you can put on your electroscope to see how charged with static electricity they are. Make a chart of the items you test and the amount of charge each has (you may want to also include columns for gained electrons, lost electrons) 2. Try using Thales method for measuring far away or very tall items. He used triangles and ratios. Pick an object in your neighbourhood (something very tall or far away) and measure it Thales way. Bring a picture and your measurements with you to class to share. Sharing Mesopotamian inventions Persephone Myth Read ch. 2 pg 11 onwards Myth vs Science Use Persephone Myth for comparison. Types of calendars; lunar, solar, tidal, Teams Mesopotamia China Egypt Islamic read chapter 3 keeping notes to compare. Compare and discuss findings.

Include which type of calendar it is, what are the pro's, what are the con's and some interesting things you have found. Feel free to make a model to share.
Optional Assignment 1. Research a type of clock and share with class. You can include who invented and when, advantages, disadvantages, uses today, how it works, reliability/accuracy. Even make a working model if you can! Here is a list of types of clocks:
"It is impossible for man to begin to learn that which he thinks he knows." ~Epictetus (ca. 55 - ca. 135 C.E.) BC (Before Christ), BCE (Before Common Era), AD (Anno Domini), CE(Common Era) meanings and problems. ca meaning: circa (Around approximately) Who is Epictetus: Freed Roman Slave What does this quote mean, Paraphrase quote, agree or disagree. Discuss Does Modern Knowledge make learning more or less difficult, why? Quest Story of Science Table of Contents, people. Read ch 1 and 2 and discussed as we went. Birthing of a Universe and Creation Myths. Looked through the stories of times and cultures. Explored Sumer and other Mesopotamian areas. Highlighted where on the map this area was, the main rivers and their importance. How moving from Nomadic to agricultural and then to cities opened space for more available time for some (not all as someone still had to do the labour). This extra time gave room to ideas, inventions, contemplation.
