TEACHER: And that is how you find the MIN/MAX on your calculator. *BOOM* Drop the mic! STUDENT: What do I put in Y1? _ _ _ _ _ _ _ _ _ No more of this! Give your students a great reference sheet to put in their notebook and NEVER ask you the keystrokes again!

This is what the entire universe looks like in one image

This is what the entire universe looks like in one image - The universe is so vast it's almost impossible to picture what it might look like crammed into one field of view. But musician Pablo Carlos Budassi managed to do it by combining logarithmic maps of the universe from Princeton & images from NASA. He created the image below that shows the observable universe in one disc. Our sun & solar system are at the very center of the image, followed by the outer ring of our Milky Way galaxy, the…

Expanding and Condensing Logarithms Math Lib

Expanding and Condensing Logarithms Math LibIn this activity, students will practice using the product property, quotient property, and power property in order to expand and condense logarithms as they rotate through 10 stations. The answer at each station will give them a piece to a story (who, doing what, with who, where, when, etc.) This is a much more fun approach to multiple choice, and the students adore reading the story to the class.

What is the Technological Singularity? The Technological Singularity is the point in the predicted near future when technology allows the artificial increase of intelligence to a level far beyond that of current human intelligence. It is best described as an intelligence explosion; the event horizon which can not be predicted beyond.

Great Lakes of Titan The existence of oceans or lakes of liquid methane on Saturn's moon Titan was predicted more than 20 years ago. But with a dense haze preventing a closer look it has not been possible to confirm their presence. Until the Cassini flyby of July 22, 2006, that is. Radar imaging data from the flyby, published this week in the journal Nature, provide convincing evidence for large bodies of liquid. This image, used on the journal's cover, gives a taste of what Cassini saw…

Logarithmic Properties Centers

This is a great classwork activity for review prior to an assessment involving Logarithms and their properties. **Centers are broken down into topics for this activity. There are 2 each of Simplifying, 2 each of Expanding, and 4 of solving equations using logarithmic properties.**

"Worksheet with list of functions that precalculus students ought to come to know very very well (y=x, y=x^2, y=x^3, y=x^-1, y=x^1/2, etc). Early in the year, I spend five minutes of class having students fill out as much of the first page as they can and then I collect them (but don't grade them). We repeat this off and on until most people can do the whole page in five minutes. Later, we do the same thing with the second page (trig, log and exponential functions).
