Students explore averages by completing a data analysis activity. In this bell curve lesson, students measure different food items and plot their measurements on a X and Y axis. Students create bell curves around the average weight or length of the specific food item and explain averages occur in all types of statistics.
High schoolers explore the concept of the bell curve. In this bell curve lesson plan, students discuss the controversy associated with the bell curve. High schoolers use an applet to explore a normal distribution. Students discuss mean, median, mode, and standard deviation in relation to skewness using an applet.
Statisticians investigate normal distribution in this lesson as they examine the area under a normal curve and use a model to find what percent of the area lies within 1,2, and 3 standard deviations of the mean. Using the TI-Nspire, they investigate an application of the normal distribution relating to the weight of each orange in a crop.
After watching Sal lead up to the finer points of probability in the previous videos, students get a chance to see him grapple with some truly complex problems. He shows viewers how to see these problems as "intuitive" by giving the answer first, and then demonstrating how he arrived there.
Students investigate normal probability distribution. In this Algebra II/Statistics and Probability instructional activity, students explore the area under the normal curve between various x-values and determine what percent of the area lies within 1, 2, and 3 standard deviations of the mean. Students apply this data to answer question about an orange crop with normally distributed weights.
Fifth graders are introduced to ways to increase their self-esteem. As a class, they share their specific talents under three categories. In groups, they use the internet to research the lives of various African Americans making sure to note their struggles and behaviors. To end the lesson plan, they set their own career goal and how to accomplish it.
You have been hired by a local newspaper to analyze the salaries for baseball players. How would you describe the data including the shape, center, and spread in the context of the problem? Interpret the differences including possible effects of outliers. Included in the lesson are facilitator notes, follow-up questions, and solutions.
Upper graders examine the concept of probability. They collect data and create a bar graph. They must interpret the data as well. Everyone engages in hands-on games and activities which lead them to predict possible outcomes for a specific event. This amazingly-thorough, 13-page plan has worksheets, video streaming links, and assessments embedded in it.
Using graphs and colorful annotations, Sal makes probability a thrill to behold in this video about binomial distribution. He takes students through additional practice so that they can "get the hang of the binomial distribution" before he begins to teach about normal distribution.
A fantastic lesson on survival in outer space should excite your learners! Pupils explore the challenges that living, working, and surviving in space elicit. They focus on the spacesuit itself; how it protects astronauts, and enables them to meet the challenges of being in space. A terrific plan!
Vapor pressure is the focus of this chemistry video. Sal explains that, when molecules are "sticking together" a substance takes on a liquid, or a solid form. But when kinetic energy is increased, the molecules are forced apart and a substance can take on a gaseous state. He goes on to illustrate (using chemistry concepts), why different substances have different boiling points, or points where a gaseous state is achieved.
The article for this activity no longer accessible through the links in the lesson plan, but can be found in the National Center for Biotechnology Information website. After reading it, environmental science students answer questions and evaluate data on the provided handout. The activity involves plotting bar graphs or histograms as well as computing logarithms, making it most useful for advanced learners.
