Positively charge protons
The scientist who proposed the plum pudding model, also known as the chocolate chip cookie dough model, was J.J. Thomson. In this model, electrons were embedded in a positively charged sphere, much like raisins in a plum pudding or chocolate chips in cookie dough.
That would be Thomson's atomic model, also called the "plum pudding model."(though I personally think a chocolate cookie is much more appetizing)
A chip model uses physical or visual representations, such as colored chips, to illustrate addition and subtraction. For addition, you can place chips of one color to represent one number and chips of another color for the second number, then combine them to see the total. For subtraction, you start with a total number of chips and remove a certain number to visualize the result. This hands-on approach helps learners grasp the concepts of these operations effectively.
Thompson described his model as plum pudding. Since not many people even know what plum pudding is, i like to describe his model as a scoop of chocolate chip ice cream. Imagine the vanilla ice cream as the positive material and the chips as the negative material.

what is an example of a small thing that a model can represent
His idea was that electrons just floated around in a pool of protons. Knowing this, you could relate the pool of protons to the dough of a cookie and the electrons to the chocolate chips located all over the dough, therefore connecting the two subjects.
J. J. Tomson was the discoverer of the electron. Using a cathode ray tube he found a particle that was deflected by a positively charged plate. Today we call cathode ray tubes televisions (at least the ones with picture tubes). He called the new particle a "corpuscle". Today we call it an electron (derived from the Greek word for "amber" which can be used to generate static electricity). Based on his research, he reasoned that the new particle had a negative charge. He proposed that an atom was like a mushy ball with raisins (electrons) stuck in the surface. Just like a tasty English holiday treat called Plum Pudding. Since atoms are usually electrically neutral (no charge), he reasoned that the mushy part had a positive charge (which would cancel the negative charge of the electron). Americans would say it was more like the electrons were chocolate chips in a scoop of chocolate chip ice cream or the chocolate chips in a scoop of chocolate chip cookie dough. (the repeated use of chocolate has nothing to do with the model). LA Dacanay

You could use raisins or chocolate chips to represent mitochondria in an edible cell model. Cut up a fruit snack or gummy candy into small pieces to represent the inner membrane folds. Arrange these components within a larger gelatin or cake base to create a visually appealing representation of a cell with mitochondria.
