Bison, bobcats, and bears, oh my! SPREE campers spent a week exploring the major ecosystems of Colorado and the plants animals that make them unique.
Campers started their exploration of Colorado ecosystems in the mountains where the South Platte River and many other waterways begin. Campers did some experiments to investigate what mountains are, what they are made of, mountain anatomy, and how they act as Colorado's "water towers!" Then, we got to explore the creek to feel connected to the water from the mountains.
Next, we learned about some Colorado mountain animals! Ungulates, animals with hooves, are one of the kinds of animals that are specially adapted to living in the mountains. Our state mammal, the bighorn sheep, lives in the Rocky Mountains! Campers made some sheep marionettes and learned some cool facts about them while acting out some of their behaviors.
Another cool Colorado ecosystem is a prairie! Prairies are a unique type of grassland found in North America- including Colorado.
Campers learned about unique features of prairies- including the types of plants, types of soils, types of weather and amounts of precipitation, and types of animals that live there. Campers delved into prairie plant adaptations with a dress up and drawing activity: they have skinny leaves to minimize water loss, super long roots to collect water, ability to grow back after fires, ability to grow back after being eaten by grazers, and more! Campers then went on a mini plant exploration hike to discover that Denver is actually built on prairie land!
Next, we learned about a few Colorado Prairie animals!
We played a game to learn about how all parts of the bison were used by Arapahoe and Cheyenne tribes, tried to lift how much bison eat in a day (24 pounds!), and played a hunting game to reenact some Native American skills.
Another animal we learned about was a prairie dog! Campers learned how they are a keystone prairie species, and we played a game to learn how they comunnicate danger, "yip, yip!"
And as always, we got time to explore the creek, cool off, and catch some critters.
Thursday: The City (Field Day)
Another important Colorado ecosystem that the river and creek flow through is cities! Many plants and animals inhabit this urban landscape, even if it may not be obvious at first! Campers took a short hike along the river trail to nearby Commons park. We learned about squirrels through an animal mystery activity and a predator and prey game. Then, we explored in the tall grasses and discovered many exciting parts of nature in the city while on a scavenger hunt!
After a picnic lunch in the park, we headed back towards camp on the trail with a stop in Confluence park to play water games and search for crawdads in the river. We caught many big crawdads and learned some cool facts about them!
Colorado has some desert regions in it, too! With very little rain, plants and animals have many cool and unique adaptations to survive the tough conditions.
We discussed a few types of desert plants with unique adaptations, but of course we primarily focused on cactus! Campers made model cactus out of clay to see that their spines are not only a defense mechanism, but they also provide shade for the plants! Next, we got to dissect a prickly pear cactus leaf to see what they look like inside where all their water and nutrients are stored.
Jackrabbits and roadrunners were some cool desert animals that campers got to learn about! We made our own jackrabbit ears while we learned about their unique cooling system. Then, we learned some cool roadrunner facts and played a game to learn about their speed and hunting skills!
Before critter crawl, we discussed how deserts typically don't have waterways running through them and what some environmental desert dangers could be (and how to help avoid them!) Then we got to get in the creek to cool off after our "heated" discussion!
Now that the campers were Colorado ecosystem experts, we wrapped up our week with a graduation ceremony!
