Can you communicate without electricity? In this activity, students explore a problem in which a school’s power has gone out and they need to deliver an important message to a neighboring first grade classroom. However, they must stay within the following constraints: they cannot use cell phones and they have to stay in their classroom while doing so. Students research and use a variety of tools and materials to build, test, and retest a device that communicates sound the most clearly while learning about and demonstrating how sound causes vibrations.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).

Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large--from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine ("It's good for you!"), it's at the core of everything that exists--including you. Having said all that, some of the specific topics we'll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That's a lot. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

There's a lot of different ways when it comes to math hacks. Here are just a few examples:

-If you're trying to do long division and are having trouble keeping track of all the digits, try using a pencil to keep track of your place. Draw a line under the number you're currently working on, and then draw a line above the number you're dividing by. This will help you keep your place and make sure you don't make any mistakes.

-If you're trying to add or subtract a large number of digits, try breaking the number down into smaller chunks. For example, if you're trying to add 753 + 872, you could break it down into 700 + 800 + 50 + 70 + 2. This will make it much easier to add up, and you're less likely to make a mistake.

-If you're having trouble memorizing your multiplication tables, try using a simple mnemonic device. For example, for the 7 times table, you could use the phrase "Seven times up, never down," which would remind you that 7 x 7 = 49. There are lots of different mnemonic devices out there, so find one that works for you.

This statistics video tutorial provides a basic introduction into standard normal distributions. It explains how to find the Z-score given a value of x as well as the mean and standard deviation. It explains how to determine the probability by finding the area under the curve represented by f(x) - the probability density function using the empirical rule and the Z-tables. This video contains plenty of examples and practice problems.

Learn how Meiosis is different than Mitosis.
To begin with What is the goal of mitosis and meiosis?
They both create new cells. Both mitosis meiosis start with diploid cells.
Mitosis creates body cells that are diploid. diploid means they have two sets of chromosomes. In humans each body cell has 23 pairs of chromosomes or 46 total.

Meiosis also creates new cells but these cells are gametes which for males is sperm cells and for females it is egg cells. These cells are haploid which means they have one set of chromosomes.

You are the living ancestor of an unbroken chain of lives stretching from you, through your mother and your grandmother all the way back through the complete history of life on planet Earth to the very first life forms that appeared around four billion years ago.
