I have taught viscosity while teaching Earth Science (viscosity of lava) and States of Matter. I actually did this lab with my students for my very first “I’m a real teacher” observation– and I got a great review! I bought all of the supplies at Dollar Tree so it wasn’t very expensive. It did make my room smell like ketchup and syrup which are two of my most hated food odors.
I don’t have a SMARTboard in my lab, but I do have one in my math classroom. I projected a timer on the board and students worked with their groups and used the timer to time how long it took to pour each liquid into a container.
My students LOVED this lab! Click on the PDF below to download.
