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.

Bridges come in a wide variety of sizes, shapes, and lengths and are found all over the world. It is important that bridges are strong so they are safe to cross. Design and build a your own model bridge. Test your bridge for strength using a force sensor that measures how hard you pull on your bridge. By observing a graph of the force, determine the amount of force needed to make your bridge collapse.

Students will practice their use of dialogue by creating a thrilling story.  They will use Scratch to create sprites and a setting that drives their story with an emphasis on writing proper dialogue.   

Students have a lot of British rulers to keep track off. This Flow Chart allows student a visual of the leaders and then to fill in with important details. There are Google Draw and print copy versions. An answer key is included.

This lesson is part of a cross curriculum unit based upon planning of a road trip.  In this lesson students research an attraction they wish to visit on their road trip.  After researching an attraction students complete a brochure describing their attraction.

This is a lesson plan to teach bruteforce and divide and conquer to elementary students. This lesson plans comes with activities and a quizlet study deck. 

 This activity will allow students to compare Brute Force and Divide and Conquer sorting algorithms.This activity will show the sorting process of a Brute Force algorithm and a Divide and Conquer algorithm that is used by a computer when sorting data.

This activity will show the sorting process using the Bubble Sort Brute Force algorithm that is used by a computer when sorting data without using a computer.

This resource consists of a Java applet and expository text. The applet simulates Buffon's coin experiment. The radius of the coin can be varied. The applet illustrates a random experiment, the sample space, random variables, events, probability, and relative frequency.

This resource consists of a Java applet and expository text. The applet simulates Buffon's needle experiment and the corresponding approximation of pi. The event of interest is that the needle crosses a crack. The length of the needle can be varied. The applet illustrates a random experiment, the sample space, random variables, probability, and relative frequency.

Students will construct equations of motion for two separate buggies. Using these equations of motion, they will predict the crashing location if the buggies are driving toward each other.

Builders and Bulldozers is a fun game that I use to help my students practice skipping, galloping, and jogging.  Instead of just performing each movement, they get to use the movements in a game.

This is an unplugged worksheet activity to walk students through the process of building strong, easy to remember, passwords.

This video explores how GigaBeam Networks is expanding and improving the quality of internet access in rural Virginia by providing fiber optic internet connectivity to its customers as well as highlighting some of the jobs available in this industry.

This lesson will help students build knowledge about sentences. Sentences are made from words and the words convey a message.

This slideshow will help students to identify and use strong passwords, and explain why strong passwords should be used (e.g., protect name, address, and telephone number). It walks students through a process that can be used to create strong, easy to remember, passwords.

A bungee jump involves jumping from a tall structure while connected to a large elastic cord. Design a bungee jump that is "safe" for a hard-boiled egg. Create a safety egg harness and connect it to a rubber band, which is your the "bungee cord." Finally, attach your bungee cord to a force sensor to measures the forces that push or pull your egg.

A zip line is a way to glide from one point to another while hanging from a cable. Design and create a zip line that is safe for a hard-boiled egg. After designing a safety egg harness, connect the harness to fishing line or wire connected between two chairs of different heights using a paper clip. Learn to improve your zip line based on data. Attach a motion sensor at the bottom of your zip line and display a graph to show how smooth a ride your egg had!

Earthquakes happen when forces in the Earth cause violent shaking of the ground. Earthquakes can be very destructive to buildings and other man-made structures. Design and build various types of buildings, then test your buildings for earthquake resistance using a shake table and a force sensor that measures how hard a force pushes or pulls your building.

Students lean about proportions, ratios, and unit rate. It is important for connections to be made among ratio tables, graphing points, and slope of a line. Students make these connections through the first activity provided by the VDOE. The second task by Illustrative Mathematics is a way to assess student understanding.
