MEL Physics "Hydrophobicity" Review October 2020

This month our experiments' theme is "Hydrophobicity" and the contents were listed on the back of our box along with a note about what we would need to prepare in advance from home. This month we just needed some vegetable oil.


Inside our box was an instruction sheet that included some general safety rules and information for the supervising adults. I love that they include this sheet so the parent can follow along but still allow the child to work independently.


If you prefer to use technology, you can also download the MEL Physics app and everything you need is there including safety and disposal information. The directions are sometimes animated and they provide scientific descriptions and further educational materials which I definitely recommend checking out!

Experiment 1: Droplet Labyrinth


I have to say that I was very impressed with how well-organized this box was! Everything was in its place and the experiments were labeled 1-3 and the baggies with supplies for each experiment had coordinating numbers on them making everything so easy to locate. The directions came on a sturdy fold-out card with illustrations and steps that I found easy to follow. Our first experiment was "Droplet Labyrinth."


For this experiment, we needed hydrophobic powder and red and blue coloring.


They provided these cool labyrinth cards, a brush to use with the powder, and a Petri dish.


They also provided a set of gloves, a black underlay to work on, and protect our table, and a paperclip to open up our bottles. We also received two different pieces of felt, one was hydrophilic (absorbs water) and the other was hydrophobic (repels water).

After looking at the materials for these projects, I felt it was safe enough for my two-year-old to observe while my six-year-old and I worked together. He put on his safety goggles and we were ready to go!



We played around with the hydrophobic paper watching the droplets roll around...right onto my table.


We placed the labyrinth card inside our Petri dish to keep the mess contained. Now it was time to add a drop of coloring to the beginning.


Then my daughter tried to navigate the droplet to the circle at the end.


Experiment 2: Oil Spill


Our second experiment was entitled, "Oil Spill."


This time we needed some of the same felt, although I was able to reuse ours from the first experiment. We also needed some of these plastic cups they provided and a dropper.


This time we were working with graphite. They provided two bottles of powder for us.




We loved how cool it looked!


Next, we dipped in our two different types of felt and observed the difference. It's a bit difficult to see here, but you could see that one absorbed only the oil. I loved that they made a real-life connection to an oil spill!

Experiment 3: Hydrophobic Sand


Our last experiment was "Hydrophobic Sand."


We received a small container of blue hydrophobic sand.


We also received some regular sand.


They also provided some coffee filters, a spoon, and some square cups.




Then we dumped the hydrophobic sand into the other cup. This one was much more interesting to observe! It never got wet!


We had some fun playing around with the sand and when we were done, we used a coffee filter to drain the water out. It was pretty amazing to see the water pass through it!

Bonus Experiment: Wettability


We also received this QR code along with a candle and some yarn so that we could perform a bonus experiment.


After scanning the code, I was taken to this experiment entitled "Wettability" which involves using a boiled egg. This will be a fun experiment to save for a rainy day!

Verdict: This was our first time receiving MEL Physics and I was so impressed with the packaging and how it included everything that we needed in the box (other than water and some oil). It was packaged neatly, everything was easy to locate, and the experiments themselves were well-explained through illustrations and included the educational information behind what we were observing. If you want to go further with the learning you can access the app for more information, or you can even check out their virtual reality app if you have a viewer! I think this was a great box and would be fun for any kid interested in physics or as a supplemental tool for homeschool learning! My kids are much too young for this box, but they were impressed, and so was I!
