Create your own shapes using colorful blocks and explore the relationship between perimeter and area. Compare the area and perimeter of two shapes side-by-side. Challenge yourself in the game screen to build shapes or find the area of funky figures. Try to collect lots of stars!

The foamy fun of "Elephant's Toothpaste," also known as the catalytic decomposition of hydrogen peroxide, helped Camille Schrier win her job as Miss America 2020! In this episode, Camille re-creates this winning chemical reaction and teaches us all about the science of catalysts and decomposition. Explore questions such as: What is a catalyst? What does a catalyst do? Why do we need a catalyst to make "Elephant's Toothpaste"? It’s a HUGE, wonderful, foamy mess that's all powered by science! Developed for students in grades 6 - 10.

In this lesson, students will be introduced to the idea of decomposition. Specifically the lesson caters to math word problems, but could be easily modified to any subject (as found in the modificaitons section of the lesson plan). Students will engage with each other and the vocab to work through an easy process to decompose word problems into manaeagable pieces as a strategy to solve. All activities are low prep and can be modified to your needs. This can be a stand alone lesson or expanded by using Part 2 and Part 3 to deepen understanding through coding activities. 

This lesson expands upon the ideas of decomposition by using GameChangineer to incorporate commands to create a coded mini game from decomposing word problems. Students will assist the teacher in this guided lesson on how to create commands and use the website before engaing independently in Part 3. Activities are low prep with modifications included, but do require organized planning to implement effectively. If you have not done a lesson on decomposition, it is suggested you use Part 1 to help student's gain the necessary understandings of the processes used in this lesson. 

This is the final part of an extended lesson on decomposition. Students will create a word problem to decompose and then use GameChangineer to create a mini game that is reflective of the word problem and its solution. Students will be using the plan, design, and review process thourhgout their creations. A rubric and self reflection tool for the final products are included. Activities are low prep with modifications included, but do require organized planning to implement effectively. If you have not done a lesson on decomposition, it is suggested you use Part 1 to help student's gain the necessary understandings of the processes used in this lesson. If you have not done a lesson on writing commands and using GameChangineer, it is suggested you use Part 2 before implementing this independent activity. 

Hands on Chemistry is a resource designed for use in traditional, online, and blended high school Chemistry classrooms. It was developed by Blue Ridge PBS in collaboration with Virtual Virginia. In this video, Chemistry teacher Fred Mitchell demonstrates decomposition using Hydrogen Peroxide and catalyst Manganese Dioxide.

Students will use decomposition strategies to predict what will happen in a story based on the pictures through the use of the 5W and 1H question words. Students will identify the characters and setting of the story and make a prediction based on the information they gained from the images.These materials were created by CodeVA in partnership with George Mason University and were funded by the National Science Foundation under Grant Award #1837380
