We’ll bring our science programs to you.
We partner with school districts to support science learning. We offer district-wide elementary, middle, and high school programs, either virtually or in-person.
We collaborate with a range of partners to innovate in science education. Together, we go further.
In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view. Learners then drip oil onto wax paper to examine what shape each drop has and whether oil drops are like water drops or different. Finally learners drip colored water drops and oil drops onto wax paper together, mix oil and water in a container, and observe how the two fluids behave when they are in contact.
