This lesson teachers students about the composition and functions of blood. As a result of this lesson, learners will be able to describe the composition and volume of whole blood, describe the composition of plasma, and discuss its importance in the body and list the cell types that make up the formed elements, and describe the major function of each type.

What happens when you drop Mentos candy into a bottle of cola? Surface area, candy glaze, carbon dioxide, and a small amount of time all make a difference. It is a short assessment geared to help students think about the phenomenon and learn what Myth Busters has uncovered in the investigation using three questions that check for understanding.

In this lab activity, students are asked to:
- Collect data on the diameter and circumference of several round objects
- Graph this data to explore the relationship between diameter and circumference
- Analyze the graph to determine a numerical value of Pi

This test consists of 10 multiple-choice questions and 3 essay questions. The test covers the motion of the sun, moon, and stars, as well as contributions made by early astronomers including Ptolemy, Copernicus, Eratosthenes, and Galileo.

This interactive simulation/movie allows students to watch the changing altitude of the sun at noon throughout the entire year. Along with the simulation is a time-lapse video showing the changing shadow of a large building, and the changing seasons outside.

This is an online lesson, which students can complete on their own either at home or in class. Students read about discoveries that were made by ancient astronomers, and how impressively accurate many of them were.

This video is used to demonstrate how observing the motion of stars can allow you to find your latitude on the earth. This video can be used very early in the discussion of star motion and is a nice compliment to the simulation found in the video, which is available here. http://astro.unl.edu/naap/motion2/starpaths.html

This project was designed for an Algebra 1 online course. The course still is designed to teach slope, even though this standard is now technically taught in the 7th and/or 8th grade. The intent was to design a project to get students to see slope in a different manner, using percent grade change of hiking paths.
The purpose of this activity is for students to use their developed knowledge and creativity to create their own system of linear inequalities. Students also collaborate in an online discussion, where they have the opportunity to graph their classmates’ systems and share what they’ve learned.
