Upper school students at St. Mark’s School of Texas have been participating in a spikeball tournament, and it’s supposed to end today.

Teams have been competing in a bracketed playoff this week.

The students are spending time outdoors, which is timely as yesterday was Earth Day. St. Mark’s released an infographic showing the results of the school’s recycling efforts. In the past year, almost 22 tons have been recycled, and environmental savings add up to 373 trees, 22 tons of carbon dioxide and more than 150,000 gallons of water.

Watch some of the spikeball highlights below.
