Today, We're Making:

• 'Homemade Ice Cream Science Experiment' - Parents can teach kids to explore chemistry by making their own homemade ice cream. They can investigate how salt turns the ice surrounding the ice cream mixture in a bag into a slush, lowering its freezing point and turning the mixture into ice cream. Further, they can experiment with different ingredients and quantities to observe changes in texture and flavour - thereby understanding the concepts of concentration, solutions and chemical reactions.
• 'Moon Map' - Given the date in July, this project could be related to the lunar landing anniversary (20th July 1969). Kids can create a 3D map of the moon using kitchen ingredients like flour.

Breaking Down the Homemade Ice Cream Science Experiment

In simple terms, the science behind the homemade ice cream is a fascinating interplay of Kitchen Science and Thermodynamics. Let's look beyond the bowl; when we freeze the ice cream ingredients, we essentially slow down their molecular motions, turning free-flowing liquids into creamy solids. This phenomenon is linked to the laws of physics and chemistry - as the temperature drops, the molecules lose energy and move slower, resulting in the consolidation of the mixture.

If we deep-dive into the Ice Cream Making Process, it’s all about balancing three core elements – ice, salt, and the mixture. The salt lowers the freezing point of the ice and causes it to melt. As it melts, it draws heat from the cream mixture, making your homemade ice cream colder and colder.

The Role of Ingredients

Digging into the role of each component, we magnify the significance of Science and Food compatibility. How about getting your hands on some Edible Experiments and whipping your homemade dessert right away?

• Cream: The fat in the cream serves as a barrier against the formation of large ice crystals, thereby giving the ice cream its characteristic smooth texture - an essential scientific recipe.
• Sugar: Also a vital player in the Homemade Ice Cream team, sugar not just sweetens but also aids in creating the soft texture. It lowers the freezing point and interrupts the formation of big ice crystals, ensuring that your homemade ice cream remains scoopable.
• Eggs: Often included in several Creamy Homemade Ice Cream recipes, egg yolks lend a rich taste. On the scientific front, the proteins in the egg yolk form a mesh-like structure, trapping both air and water molecules. This results in the smooth, dense consistency we all love.

The Science of Churning

Churning or agitation interrupts the formation of ice crystals, making them extremely small, and adds air to the mixture. Hence, while crafting your DIY Ice Cream, it is necessary to keep the mixture moving during the freezing process. This will help you achieve that light and luscious texture which is the soul of creamy homemade ice cream.

The Homemade Ice Cream Science Experiment is not just a delightful culinary experience but also a great way to engage in home science experiments. It is empowering to understand how simple ingredients undergo transformations and create something delicious and gratifying!

Baking Soda and Vinegar Experiment - A STEM project

Objective: To learn and understand the concepts of concentration, reaction and chemical changes.

Ingredients

• 1 tablespoon of baking soda
• 1/2 cup of vinegar
• 1 glass
• 1 teaspoon
• 1 measuring cup

Instructions

• Step 1: Measure 1 tablespoon of baking soda and pour it into the glass.
• Step 2: Measure 1/2 cup of vinegar using a measuring cup.
• Step 3: Slowly pour the vinegar into the glass containing baking soda.
• Step 4: Watch the reaction. The mixture should bubble and fizz. This is because a chemical reaction is taking place between the baking soda and vinegar, forming carbon dioxide gas.
• Step 5: Discuss the results. Ask your child to explain why the reaction happened. This will help them to understand the concept of chemical reactions.

Further Experiments for Understanding Concentration

Objective: Experiment with different quantities of baking soda and vinegar to understand how concentration affects the reaction.
