Hypothesis Testing - Solving Problems With Proportions

Hypothesis Testing - Solving Problems With Proportions Teacherflix 9 Views • 2 years ago

This statistics video tutorial explains how to solve hypothesis testing problems with proportions. It explains how to calculate the sample proportion and the z-test statistic and how to compare that with the critical values in order to determine whether or not if you should accept or reject the null hypothesis at a specified confidence level or significance level.

Periodic Table of Elements for Kids | Learn all about the elements on the Periodic Table

Periodic Table of Elements for Kids | Learn all about the elements on the Periodic Table Teacherflix 3 Views • 2 years ago

What is an element? And how many known elements are there in the vast universe? Periodic Table of Elements for Kids answers these and other questions and explains how the table came to be in the first place. Elements make up everything in the whole world, so it makes sense to learn a little more about them. The Periodic Table provides us with a lot of valuable information about these different atoms.

The first person to propose that scientists arrange the elements in a table was Dmitri Mendeleev in 1869. At the time, there were only 65 known elements, and Mendeleev arranged them according to their atomic weights as well as by their similar properties. Today, the table has seven rows, called periods, and 18 columns, called groups. The elements in each group have similar properties. For instance, the elements that can be classified as alkali metals all align in one group.

What you can learn about each element on the table depends on which table you look at. Some provide more information than others. For the most part, you can discover the element's name, atomic number, atomic weight, and symbol. Many symbols reflect the name of the element. For instance, the symbol for calcium is Ca. Others reflect the Latin origins of the word, such as for gold, the symbol for which is Au.

We hope you and your student(s) enjoyed learning about the many elements on Earth! If you want to learn even more, head over to our website and download one of our many free lesson plans about atoms or elements, full of activities, worksheets, and more!

ASL 20th Century for Kids

ASL 20th Century for Kids Teacherflix 5 Views • 2 years ago

A century is a pretty long period of time, so a lot can happen in those hundred years.

Right after that global pandemic, scientists developed insulin and penicillin, which saved millions of lives. This is also when the Great Depression occurred, and many people lives and lifestyles changed drastically.

In the next few decades, Amelia Earhart took flight, the Monopoly board game made its debut, and the second World War began and ended. In addition, the time around the middle of the century introduced M&Ms and Cheerios to the world. Velcro, color TV, and seatbelts were all invented in the 1950s, and this is also when Charlie Brown, Disneyland, and McDonald's started.

One of the most significant decades is the 60s, which focused a lot of civil rights. This is also the decade during which man stepped on the moon, the first super bowl was held, and the Beatles became famous.

Farms and Food for Kids | Learn how food comes from a farm to your table

Farms and Food for Kids | Learn how food comes from a farm to your table Teacherflix 35 Views • 2 years ago

Did you know that most of the food you eat started out at a farm? There is a whole system in place to get your food from its origin at a farm to your plate on the table. In Farms and Food for kids, you will learn all about this process and discover some fun facts about what your food goes through as it travels from farm to you.

A farm is usually a large area of land used to grow crops or raise animals for the production of food. Farms are the main source of food for people all over the world. Farmers are the people who work on or own and manage a farm. Most farms are specialized today, meaning that they focus on one or a few select crops or animals. Without farms, many people in the world would go hungry.

So how does food get from a farm to you? It goes through several steps, and this video talks about some of them specifically. First, farmers prepare the land by turning the soil with a plow. Then the seeds get planted by a seeder, and the crops get watered. Sometimes, farmers will also spray fertilizers to help the crops grow or pesticides to keep pests from ruining the crops.

Once the crops are ready, they are harvested and then stored. Farmers then transport the goods to wholesalers like restaurants and retailers. Finally, retailers place the food on the shelves for us to buy them. Sometimes, food goes through processing plants that help that food last longer. Other times, smaller farms can sell their food at farmers markets directly to consumers!

We hope you and your student(s) enjoyed learning about the importance of farms! If you want to learn even more, head over to our website and download one of our many free lesson plans about farms and food, full of activities, worksheets, and more!
