Children have many questions and interests about worms, but parents won't allow them to dig up worms in the dirt to observe them because it can cause health problems in children, so nothing is more important than having a bowl full of worms for children to observe. Today, the alpha science classroom teaches kids DIY Heat Sensitive Worms, a fun children's chemistry experiments activity that uses fascinating polymer materials to help kids make safe and fun worms, allowing kids to experience the magic and fun that comes from kids' science experiment activities.

Alpha Science Class: DIY Heat Sensitive Worms Experiment Steps
Step 1: First, the children measure out 1 cup (8 ounces) of warm water in a transparent cup or glass, pour it into a bowl, and add 1 scoop of blue worm activator powder, and stir.
Step 2: The children are turning 1 blue spoon equal to 1 teaspoon or 3 grams of worm activator, just in case you lose the blue spoon. Before proceeding to the next step, make sure most of the worm activator is dissolved in the water.
Step 3: Now that the children have the worm activator solution, spray a small amount of worm slime into the bowl. Watching the slime turn into a long silkworm!
Step 4: Now, the children must change that worm back to a beautiful blue. Remove the worms from the warm activator solution and put the worms in a glass or bowl of cold water (the colder the better). Depending on the thickness of the worm, the change back to blue may be instant, or it may take a minute.
Step 5: Put the worms back in warm or hot water and turn them back to blue.
Alpha Science Class: DIY Thermal Worm Experiment Principle
The alpha science classroom tells the children that when you made Insta-Worms, you were learning the science of polymers. The real name of this liquid is sodium alginate. Sodium alginate is a long-chain molecule called a polymer. Polymers are large molecules made by linking many smaller molecules together. Specifically, sodium alginate is a polysaccharide isolated from seaweed. Polysaccharides such as starch and alginate are made by linking together hundreds of glucose (sugar) molecules. Alginate is commonly used as a thickener in foods such as ice cream and fruit pies. Now that you know this chemical secret, next time you go to the grocery store, check the food label to find out which other foods contain sodium alginate. Alginate compounds are also used in dental impression materials and wound dressings.
The long worm is very lifelike. In the process of DIY heat-sensitive worms, children also learned about the worm's discoloration characteristics and the magic of polymers. Then children can develop their own thinking, observe and record the time and process of discoloration of hot insects for better understanding. So, today's kid's science experiment activities in Alpha Science Class are over. I hope this children's chemistry experiments activity will help children spend a happy time full of science and magic.
Alpha Science Toys has prepared disgusting science experiment kits for children to help them understand the magical mysteries of different insects and bacteria so that children can become the most powerful scientists.
