If you are like me, you hate spending time setting up different projects for your toddlers or children to only play for a few minutes. No need to worry about that with this fun science & sensory activity.

Just note that this is messy, so it may be one you want to do outside.

What is Oobleck?

Oobleck refers to a green substance from the Dr. Seuss book,Bartholomew.This is a great way to add a literary component to your science experiments.

And don’t worry about this particular Dr. Seuss book being appropriate. It is not one that is being questioned for being appropriate for children in this day in age.

Basic Recap Of The Story

A boy named Bartholomew must solve a problem caused by a strange green oobleck that falls from the sky, disrupting his kingdom. He persuades the King that he made a mistake and is able to reverse the Oobleck problem they were facing.

How To Use For Science Experiments

The best part of this fascinating substance is that you can discuss different states of matter with your littlest scientists. Since Oobleck is a non-Newtonian fluid it is a great way for young children to see and feel the liquid state and a solid at the same time.

The amount of pressure applied to the mixture of cornstarch determines if it is in liquid form or solid.

Is it a liquid? Is it a solid?

Even adults will have so much fun playing with this Oobleck experiment. I guarantee you will be tempted to have some fun with your little ones.

Recommended Supplies

The best part is that it only takes two ingredients: cornstarch and water! Just note that the ratio of cornstarch to water may vary depending on your climate and altitude.

Food Coloring vs. Washable Paint

Gel food coloring will give more vibrant colors, but may stain your hands. If you are not worried about a child putting anything in their mouth, you could use a little washable tempera paint instead.

Step 3: Have Fun Playing

You can bury toys and cars. Just use your hands to see how it changes states of matter.

What do you observe?

This is a great question you can your little ones to see if they can come up with any scientific conclusions about what is going on with this crazy material!

The Ooleck will look like it is breaking if you add too much pressure when trying to pick it up. And you will notice that if you don’t apply any pressure, your fingers will slowly sink into the Oobleck or it will run through your fingers.

Step 4: Clean Up

You can save Oobleck for about 24 hours in an airtight container. It may last longer but check for mold after that timeframe.

After 24 hours, you can also let the water evaporate so that you can reconstitute the cornstarch at a different time. Once it dries, you could consider making cloud dough with lotion or even conditioner.

Insights, advice, suggestions, feedback and comments from experts

As an expert in educational activities for children, I can provide information related to the concepts used in the article about making Oobleck. Oobleck is a non-Newtonian fluid that behaves like both a solid and a liquid. It is made using a simple recipe with cornstarch and water, and it provides a great sensory play material for kids.

Non-Newtonian Fluid

A non-Newtonian fluid is a type of fluid that doesn't follow Newton's law of viscosity. Newtonian fluids, like water, have a constant viscosity regardless of the applied force. However, non-Newtonian fluids, like Oobleck, change their viscosity when subjected to stress or pressure. Oobleck becomes more solid-like when pressure is applied and more liquid-like when the pressure is released.

States of Matter

Oobleck is an excellent material to teach children about different states of matter. It allows them to observe and experience the properties of a liquid and a solid simultaneously. The amount of pressure applied to the mixture of cornstarch determines whether it behaves like a liquid or a solid.

Recipe and Ingredients

The recipe for Oobleck requires only two ingredients: cornstarch and water. The ratio of cornstarch to water may vary depending on your climate and altitude. Start with mixing 2 parts cornstarch with 1 part water and adjust until you achieve the desired consistency. You can add food coloring or washable tempera paint to create different colors.

Activities and Tips

There are several fun activities you can do with Oobleck. You can bury toys or small items in the Oobleck and have your child find them using their hands or utensils. You can also observe how the Oobleck changes its state when pressure is applied or released. It's important to note that Oobleck can be messy, so it's recommended to do the activities outside or in a controlled environment.

Cleaning Up

Cleaning up Oobleck can be easier if you let it dry before attempting to clean it. Once it dries and turns back into a powdery form, you can vacuum it up or dispose of it in a plastic bag. It's not advisable to pour Oobleck down the drain, as it can cause clogs.

Alternative Ingredients

If you don't have cornstarch, you can try using other starchy flours like tapioca flour, potato starch, or arrowroot flour. The ratios may need to be adjusted, so it's best to experiment. Another alternative is using baby powder to make Oobleck.

Conclusion

Oobleck is a fun and educational activity that children and adults can enjoy. It provides a hands-on way to explore the properties of non-Newtonian fluids and different states of matter. With just a few simple ingredients, you can create a sensory play material that will keep your children engaged and entertained.
