We've talked about mixtures and solutions, solutes and solvents, but what about things that can't be undone? What about Chemical Changes? Would it surprise you to know that baking a cake is a Chemical Change? Or striking a match? In this episode of Crash Course Kids, Sabrina talks to us about how to tell if you have a chemical change on your hands.

As a class, students use a low-cost air quality monitor (a rentable “Pod”) to measure the emissions from different vehicles. By applying the knowledge about combustion chemistry that they gain during the pre-activity reading (or lecture presentation, alternatively), students predict how the emissions from various vehicles will differ in terms of pollutants (CO2, VOCs and NO2), and explain why. After data collection, students examine the time series plots as a class—a chance to interpret the results and compare them to their predictions. Short online videos and a current event article help to highlight the real-world necessity of understanding and improving vehicle emissions. Numerous student handouts are provided. The activity content may be presented independently of its unit and without using an air quality monitor by analyzing provided sample data.

Have you ever wondered why it takes such a long period of time for NASA to build space exploration equipment? What is involved in manufacturing and building a rover for the Red Planet? During this lesson, students will discover the journey that a Mars rover embarks upon after being designed by engineers and before being prepared for launch. Students will investigate the fabrication techniques, tolerance concepts, assembly and field-testing associated with a Mars exploratory rover.

Students groups create scientific research posters to professionally present the results of their AQ-IQ research projects, which serves as a conclusion to the unit. (This activity is also suitable to be conducted independently from its unit—for students to make posters for any type of project they have completed.) First, students critically examine example posters to gain an understanding of what they contain and how they can be made most effective for viewers. Then they are prompted to analyze and interpret their data, including what statistics and plots to use in their posters. Finally, groups are given a guide that aids them in making their posters by suggesting all the key components one would find in any research paper or presentation. This activity is suitable for presenting final project posters to classmates or to a wider audience in a symposium or expo environment. In addition to the poster-making guide, three worksheets, six example posters, a rubric and a post-unit survey are provided.

Students use the robot paths they documented during the associated Robots on Ice Engineering Challenge activity to learn about and then make artwork. During the previous activity, students recorded the path of their robots through a maze in order to collect data during a remote research simulation. Now, they take a new look at the robot paths, seeing them from an art perspective as continuous line drawings. Students learn about Picasso’s famous works of art that used the same technique. Then they learn the artistic definition of a line and see examples of how it is used in different art pieces; they practice making continuous line drawings and then create sculptures of their drawings using colorful wire. A PowerPoint® presentation is provided to guide the activity.
