February 10: Hatching Dino Babies
This activity bubbles to life when we wet some baking soda and pad it around our baby dinosaur. Add a little bit of vinegar and WOAH! Watch as the little dinosaur “hatches” from the egg! You can do this at home yourself: 1/2 cup of baking soda, add water until paste (optional: add a few drops of food coloring to the mix as well as a tablespoon of dishsoap – it’ll make your bubbles last longer and give them a fun color). Add a tablespoon at a time of vinegar on top to see the reaction! Come hatch a dino with us!

For our activity today, we’ll learn about their amazing spiral shape and make our own ammonites out of coils of clay to take home! Come learn about this awesome fossil with us!

June 9: Sand Turned to Stone: Sandstone!
Sandstone is the type of rock that makes up most of Dinosaur Ridge (and Red Rocks Park). It’s made by sand being buried and stuck together over time with other minerals growing and acting like glue. Come join us as we make our OWN sandstone with colorful sand and glue, and once it dries – we’ll have a model of sandstone!

November 10: Watercolor Leaves and Petals
How colors mix and blend is always so fun to play with! Today, we’re going to look at how flowers take water and how it may change the color of the flower petals after it drinks through the stem! Join us as we use markers to brightly color coffee filters, and then dip them in water to see how the colors blend and mix! This is just like when a flower drinks colorful water and changes the color of its petals!
