Learning French through science

Easy science experiment for kids: making oobleck in French

What is oobleck and what makes it a great science experiment for kids? Inspired by Dr. Seuss’ Bartholomew and the Oobleck, it is a substance that can change its form without any change in temperature. It is just one example of a non-Newtonian fluid. Other examples are ketchup and silly putty, both of which exhibit liquid-like properties when poured but act like a solid when under force.

Making this fascinating goo only takes a few steps and a couple of ingredients that you most likely already have in your pantry. Since it involves pouring, mixing, and squeezing, children get to work on their fine motor skills. And once the oobleck is ready, playing with it is not only fun but also a great sensory experience for kids.

Conducting this science experiment for kids in French will enable your kids to discover or practice vocabulary related to measuring ingredients and action verbs involved as they follow the instructions.

Be warned that this experiment is quite messy, but I guarantee that the look of amazement on your child’s face is well worth it!

Transition words

If you want to enrich this activity further, you can add transition words to draw their attention to the sequence of steps.

  • Tout d’abord (first)
  • Ensuite, puis (then)
  • Maintenant (now)


You can also focus on colour vocabulary. You can use individual colours or mix different colours to see what they produce.
