Chemistry Science Lessons PowerPoint-Radioactive Beans Do your students understand exactly what is happening when a radioactive atom decays? If not, they will after doing this fun activity. More-free Radioactivity Quiz Need a quiz on radioactivity you can use to test students with, or just to see what they know? Have them take this 10 question true/false quiz. Presented in 4 variations. More-free PowerPoint-Radioactive Samples Learn about the 3 kinds of radioactivity- alpha, beta, gamma- by viewing actual samples of polonium, strontium, and cobalt, and then discussing what each does over time. More-free "The Elements" by Tom Lehrer If you've never heard this, you're missing out. Prove to your students once and for all that chemists do have a sense of humor...at least among themselves. More-free PowerPoint-Balancing Chemical Equations Includes 4 problems that students can work through. They start easy so students can see what's going on and build confidence. More-free PowerPoint-Isotopes & Ions Confused about isotopes and ions? Let this PowerPoint help straighten you out. Presented in 2 versions-normal and the short version, which your students can do on a blank sheet of copy paper or on the handout provided. Choices abound! More-free PowerPoint-Difference 1 Proton Makes This demonstration reinforces what protons are, where they are, and just how important they are by illustrating what happens when 1 little bitty proton is added or removed. More-free Premium Chemistry Science Lessons -Stronger Lessons, Stronger PowerPoints Interactive Notes-The Atom In this set of interactive notes students observe: 1.a sugar cube that gives us an idea of how small atoms are, 2.another kind of sugar that sparks, proving electrons exist, 3.an a-maze-ing demo that helps us understand how we know anything about something so small, and 4.bar magnets that provide clues about the other two kinds of particles- protons and neutrons. More Dot Diagramming-Understand The Placement Of Protons, Neutrons, And Electrons Dot diagramming is an important bridge between 2 major chemistry concepts- atomic structure and then how these atoms combine into molecules. This activity feels more like a puzzle than a typical science lesson. More Counting Atoms-An Investigation Into The Nanoworld Of Atoms How can you measure something that’s so small that it’s never been seen? In this challenging but fun lesson students will count the number of atoms in a metal cube not with their eyes, but with mathematics. More Clay Atoms-Taming Our Fear Of The Invisible Most students are uncomfortable with atoms because they assume that since atoms are small they must be hard to understand. This fun activity will disprove that as students use clay to mold protons, neutrons, and electrons that they’ll combine to make atoms. More Periodic Pencil Classification-Understanding Chemistry's Cornerstone Watch as students progressively organize a group of pens and pencils using a scheme they devise themselves. And then spring a big surprise- their table relates to the Periodic Table in many ways! More Interactive Notes-Physical And Chemical Change In this set of interactive notes students observe: 1.an egg changing its mind, 2.what happens when you light rocket fuel, 3.an invisible force snuff out a candle, and 4.a who-dunnit mystery that will identify Santa's non-believer.
