Students study sea surface height and temperature and other characteristics of an El Nino.  For this ocean impacts lesson students examine the factors that influence an El Nino or La Nina. 

Can you follow a composition of transformations, or better yet construct them? Young mathematicians analyze the composition of dilations, examining both the scale factor and centers of dilations. They discover relationships for both...

Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

Don't get out of order! Examine the effect of order on a sequence of transformations. Learners perform reflections and translation transformations in sequence. They see that changing the order of the transformations does not always have...

A few class periods will be required to complete this physics investigation with your high schoolers. There is an unavailable video written into the lesson plan, but there is plenty of material here to bridge the gap. Two terrific...

Young scholars compare bacteria and viruses and their roles in biotechnology and bioterrorism. They outline fundamental steps of bacterial transformation and the possible selection processes to identify transformants. They discuss...

In this algebra worksheet, students solve systems of equations using matrices. There are 24 questions to be solved.

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

Emerging engineers perform pre-lab calculations in this first of a three-part lesson on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw a draft of their...

Wow! A very detailed slideshow covers complex topics of genome research methods. This is advanced and relevant to the highest level of school biology. Excellent resource if you wish to expose your class to scientific methods and...

All phenomena concerning magnets, their field lines and impact on objects are covered. The trivia surrounding field lines and the earth, electric charges, repulsion and attraction is plentiful. The slide show continues after twenty...

For each of eight diagrams of objects in motion, physics masters draw pie charts to depict the changes in energy. For each they must identify the energy conditions at each position. This is a unique worksheet, perfect for assessing how...

Future physics majors look at a diagram of a marble rolling across a railing. They sketch motion maps and force diagrams. They determine the horizontal range of the marble as it falls to the floor. Then they double the height and repeat...

Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...

Forgot how to multiply matrices? Well, this app can help. It is like a gigantic, well-organized reference card for all things math. Customize your personal reference material by adding your own notes and build up a personalized list of...

Accelerate young physicists' learning with this collection of problem-solving worksheets. Starting off by teaching learners to identify the given information and variables in physics problems, this resource goes on to challenge them...

Fractions, ratios, and proportions: what do they have to do with segments? Scholars discover the midpoint formula through coordinate geometry. Next, they expand on the formula to apply it to dividing the segment into different...

Class members use a compass and several points to map out the magnetic field of a magnet. Pairs trace the magnetic field lines produced by a permanent magnet by positioning the compass in numerous spots around the magnet to view the...

To work through the complexity of coordinate geometry pupils make the connection between the coordinate plane and the complex plane as they plot complex numbers in the 11th part of a series of 32. Making the connection between the two...

Video game characters move straight with matrices. The first day of a two-day lesson introduces the class to linear transformations that produce straight line motion. The 23rd part in a 32-part series has pupils determine the...

Class members make a real connection to matrices in the 25th part of a series of 32 by looking at the identity matrix and making the connection to the multiplicative identity in the real numbers. Pupils explore different...

Explore the history of cholera and its effect on society with your biology class. Young biologists will then proceed to grow their own germs, prepared from live cultures, and follow the steps of the scientific method to generate data....

Use the coordinate plane to show two figures are similar. The instructional activity incorporates congruence transformations and dilations to move a figure on to another figure. Pupils determine that if a similarity...

Examine the various rigid transformations and recognize sequences of these transformations. The lesson asks learners to perform sequences of rotations, reflections, and translations. Individuals also describe a sequence that results in...
