This short video and interactive assessment activity is designed to give fourth graders an overview of 24-hour clocks.

These lesson plans and activities were developed by Janine Darragh, Gina Petrie, and Stan Pichinevskiy and were previously located on the Reaching for English app. Created for K-12 English teachers in Nicaragua, the materials may be used and adapted for any country's specific context and needs.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Vitamin D guidelines are currently in a state of paralysis. The problem: the numerous competing ways of measuring levels of 25-hydroxyvitamin D, a slightly modified form of vitamin D in the body. This lack of standardization has produced three conflicting sets of guidelines for defining vitamin D status across the globe, those from the UK, the US, and the Endocrine Society. The guidelines from the UK and US set similar standards, defining vitamin D deficiency as 25-hydroxyvitamin D concentrations less than 10 to 12 nanograms per milliliter. This is the standard typically adopted by government-sponsored committees. Non-governmental organizations, however, tend to adopt the guideline set by the Endocrine Society, which defines deficiency as 25-hydroxyvitamin D concentrations less than 20 nanograms per milliliter. Despite a wealth of data on vitamin D and how to measure it, a worldwide consensus on determining vitamin D status remains elusive..."

Coders use a variety of blocks and customized sprites to create their own interactive diorama about a jungle. The purpose of this project is to reinforce the concept of parallelism to trigger two or more algorithms simultaneously.

This lesson will allow students to select and share what details are important on a topic.  Groups of students will research a topic and then discuss and determine the top 25 important things someone should know about the topic.

This eLesson by Dr. Felix Yerace will provide students with an opportunity to learn about the text of the Twenty-Fifth Amendment as well as its historical usage and potential need. It will ask them to consider why such an Amendment was deemed necessary and how it has been, and could be, used. It will also give students the opportunity to debate possible applications of the Twenty-Fifth Amendment.

Coders use a variety of blocks and sprites to create an interactive aquarium. The purpose of this project is to apply previously learned concepts in a new context (e.g., creating or modifying sprites, parallelism, events, etc.).

This lesson explores the most recent constitutional expansion of voting rights: extending them to people between 18 and 21 years of age. Students will read the 26th Amendment and learn about its history. They will view an NBC report from Nov. 5, 2008, that explains how important the youth vote was to the election of Barack Obama. Finally, they will examine the results of a recent study showing that young voters have very different concerns than older voters, and hypothesize about how young voters might affect elections in 2012 and beyond.

Coders use a variety of blocks in parallel to create simulations (e.g., dribbling a ball). The purpose of this short project is to apply previously learned understandings in order to simulate motion.

Coders learn how to use the “go to page” blocks to create a multi-page story about a rainy day. The purpose of this project is to introduce coders to the “go to page” blocks and to apply previous understandings across multiple pages.

Coders use the repeat block to repeat a silly dance for Scratch Cat using motion blocks. The purpose of this project is to introduce young coders to repeating algorithmic sequences in ScratchJr.

This lesson unit is intended to help teachers assess how well students are able to visualize two-dimensional cross-sections of representations of three-dimensional objects. In particular, the lesson will help you identify and help students who have difficulties recognizing and drawing two-dimensional cross-sections at different points along a plane of a representation of a three-dimensional object.
