Scientific Method RapFirst you make an observation of the world around Take notes and record all the things that you found Then you ask a simple question something that you want to learn Then you form a hypothesis to explain what you observed Then you make a prediction about how it's gonna go Do a test with a control and variable Then you analyze the data and draw a conclusion Do the scientific method to avoid all confusion ChorusMake an observation Ask a question Form a hypothesis And make a prediction Do a test or experimentation Analyze data and draw a conclusion Scientific MethodThe Atom’s FamilyThey're tiny and they're teeny,Much smaller than a beany,They never can be seeny,The Atoms Family.They are so small.(Snap, snap)They're round like a ball.(Snap, snap)They make up the air.They're everywhere.Can't see them all.(Snap, snap)Together they make gases,And liquids like molasses,And all the solid masses,The Atoms FamilyNeutrons can be found,Where protons hang around;Electrons they surroundThe Atoms FamilyMeniscus Song(Slow) When you measure liquids, with a graduated cylinder. Put the cylinder on a flat surface first, Then pour the liquid inside, Up to the volume you want in there.But you must re-mem-ber, you want a very precise mea-sure-ment, The volume of the liq-uid so ex-act, A pipet ----- will help you with that, But there's some-thing impor-tant. Something important..... you must ---- look at!Look at the bottom, the bottom, the bottom, the bottomof the meniscus, the meniscus, the meniscus You can see a curve, at the top of the liq-uid, Its shape is con-cave and not straight, There's a reason it's curved it's because, Because of the liquid's molecules.The molecules have, a very strong at-trac-tion. For the sides of the cyl-in-der. So the surface is curved downward, that's the spot you look at. The meniscus, the meniscus, the men-is-cus!Look at the bottom, the bottom, the bottom, the bottom of the meniscus, the meniscus, the meniscus, Look at the bottom, the bottom, the bottom, the bottom of the meniscus, the meniscus, the meniscus, Look at the bottom, the bottom, the bottom, the bottom of the meniscus, the meniscus, the meniscus, Look at the bottom, the bottom, the bottom, the bottom of the meniscus, the meniscus, the meniscus,Your measurements done the right way, look at the bottom of the shape that's concave, You'll be so precise............ when you measure liq-uids! (slowly)The periodic Table song's Hydrogen and HeliumThen Lithium, BerylliumBoron, Carbon everywhereNitrogen all through the air?With Oxygen so you can breatheAnd Fluorine for your pretty teethNeon to light up the signsSodium for salty times?Magnesium, Aluminium, SiliconPhosphorus, then Sulfur, Chlorine and ArgonPotassium, and Calcium so you'll grow strongScandium, Titanium, Vanadium and Chromium and Manganese?CHORUSThis is the Periodic TableNoble gas is stableHalogens and Alkali react agressivelyEach period will see new outer shellsWhile electrons are added moving to the right?Iron is the 26thThen Cobalt, Nickel coins you getCopper, Zinc and GalliumGermanium and Arsenic?Selenium and Bromine filmWhile Krypton helps light up your roomRubidium and Strontium then Yttrium, Zirconium?Niobium, Molybdenum, TechnetiumRuthenium, Rhodium, PalladiumSilver-ware then Cadmium and IndiumTin-cans, Antimony then Tellurium and Iodine and Xenon and then Caesium and...?Barium is 56 and this is where the table splitsWhere Lanthanides have just begunLanthanum, Cerium and Praseodymium?Neodymium's next tooPromethium, then 62'sSamarium, Europium, Gadolinium and TerbiumDysprosium, Holmium, Erbium, ThuliumYtterbium, Lutetium?Hafnium, Tantalum, Tungsten then we're on toRhenium, Osmium and IridiumPlatinum, Gold to make you rich till you grow oldMercury to tell you when it's really cold?Thallium and Lead then Bismuth for your tummyPolonium, Astatine would not be yummyRadon, Francium will last a little timeRadium then Actinides at 89?REPEAT CHORUS?Actinium, Thorium, ProtactiniumUranium, Neptunium, PlutoniumAmericium, Curium, BerkeliumCalifornium, Einsteinium, FermiumMendelevium, Nobelium, LawrenciumRutherfordium, Dubnium, SeaborgiumBohrium, Hassium then MeitneriumDarmstadtium, Roentgenium, Copernicium?Nihonium, Flerovium Moscovium, Livermorium Tennessine and Oganesson And then we're done!!Groups and Periods SongV.1 The periodic table looks complex but it's organized in ways you'll find that do make sense. The groups or families are arranged in columns but the periods are in long rows.V.2 The groups of elements have family names, because some of their properties are very much the same. Things like re-ac-ti-vi-ty, especially, those are the columns.CHORUS: The group number tells us how many electrons are in the atom's outer shell. The period number tells us how many electron energy levels that there are.V. 3 Alkali metals - family name - for elements in Group 1 or I A , There's only one electron present in - the outer energy le-vel. CHORUSV. 4 The Halogens - family name - for elements in Group 17 or VII A. There's seven electrons present in - the outer energy le-vel. CHORUSV. 5 The Noble Gases - family name - for elements in Group 18 or VIII A. Their outer shells are always filled, so they don't need, to bond with an element.They're the Noble Gases ....... They don't bond with any element. (Brief interlude) They're the Noble Gases ....... They don't bond with any element. (Brief interlude) They're the Noble Gases ....... They don't bond with any element !Mass Versus WeightMass versus weight -- two measures for an object. They're not the same, let's all see why! To determine the mass, we use a balance to do it. We use a scale to measure weight.Mass, measured in grams, or in kilograms, It's all about how much stuff - the object has!Grams or kilograms (ba! ba! ba!)They're the units we use for mass. (for mass, for mass, for mass).Newtons are for weight (ba! ba! ba!)Weight's the measure of gravity's pull on the ob-ject.So you can see, mass and weight aren't the same thing. Weight is the measure of gravity's pull! In contrast to weight, mass tells us how much matter, How much matter the object has.Mass, measured in grams, or in kilograms, It's all about how much stuff - the object has!Grams or kilograms (ba! ba! ba!)They're the units we use for mass. (for mass, for mass, for mass).Newtons are for weight (ba! ba! ba!)Weight's the measure of gravity's pull on the ob-ject.Mass and weight, mass and weight, they're not the same. Mass and weight, mass and weight, they're not the same. Mass and weight, they're not the, not the same.Grams or kilograms (ba! ba! ba!)They're the units we use for mass. (for mass, for mass, for mass).Newtons are for weight (ba! ba! ba!)Weight's the measure of gravity's pull on the ob-ject. ................
