After learning about their adaptations, we will go on a fun nature walk-in Alum Rock Park to see what we can find together! Insects tend to love coming out after a rain, so dress accordingly! After exploring, we will come back to do a fun craft together! Our instructors have created personal kits for each child, so they can be artistic while being safe! You'll come in the morning as children, and leave as Junior Entomologists!
