Students prepare to launch weather balloon
MORRISON – Twenty-five students and Teacher Bob MacArthur spent the morning of Saturday, April 4 flying a balloon. All the way to an altitude of 63,044 feet - almost 12 miles above the mile high city.
The Highlands Ranch High School teacher and students from his meteorology class, complete with a pink marshmallow Peep in commemoration of Easter. The Peep and other specimens were launched with the balloon in order to observe the impact of dramatic changes in altitude, pressure and temperature, plus exposure to radiation.

District News

DCSD is requesting parent input on the health and wellness of our students. Last year, DCSD received a large planning grant from Colorado Health Foundation in an effort to assess how the district supports students through the lens of the Whole School, Whole Community, Whole Child model (WSCC). The mission of this grant is to review the current state of DCSD's student health and wellness program, and then formulate a three to five-year plan based on stakeholders’ needs, the latest research, and best practices. As part of this process, we would like your input.

How are we doing?

We want to hear from you! How often do you prefer to receive email newsletters from DCSD? How can we improve the news and information you receive? This brief survey should only take a minute or two of your time. Thank you for giving us your input!

Tell us what you think, here!

It may look like a plain, white shipping container was just parked on the backyard grounds of Mountain Vista High School. The contents of the container are anything but plain, though. Walking inside the container, different colors of ambient lighting glow, futuristic-looking equipment and tall towers are suspended from the ceiling, and the humidity level is set to 70 percent. The container has been recycled into a new kind of learning opportunity for students.
