Please enjoy this easy slime video tutorial. This activity is recommended for children ages 4-8 with parental supervision.
- 4 ounces glue or melted stick glue
- 4 ounces warm water
- Shaving cream
- 2 ounces of liquid laundry detergent
- Food coloring (optional)
- Lotion (optional)
Slime is cool for many different reasons. It’s not just fun to play with, it also teaches us a lot about science!
Slime is a sticky substance, but why? Glue is an important part of the answer. Glue is a key ingredient of slime. It is made up of molecules (a group of really small pieces called atoms) that are long and flexible. These molecules are called polymers. When the glue polymers move past each other, they act like liquids (think of water). But when the glue molecules mix with the molecules of the other ingredients, the glue molecules begin to stick to each other because of a chemical reaction. This makes it harder for the glue polymers to flow and move around. When this happens enough times, the substance becomes rubbery and sticky!
Just like when you bake a cake, you must follow certain directions when you make slime.You have to carefully mix the ingredients together or else your slime will be too runny or too sticky! When you put these steps together, you are following something called the scientific process by doing an experiment!
In real life, slime can actually be used for cleaning! Slime can help remove dust from keyboards and hard to reach places but we recommend you wait for adult permission before trying that at home. Some say that playing with slime is also a great way to relieve stress!
PROPERTIES OF SLIME INVESTIGATION
In science, it is important to investigate. Investigating the properties (traits or specific details) of a sample can help you understand it better. By using your sense of sight to observe or by using your sense of touch to compare textures, you can learn a lot! Scientists like to investigate using different methods like observation or measurement. They have made lots of cool discoveries by paying attention to small details and so can you! Here are some questions and fun tests to perform on your slime sample!
HOW FAR CAN YOUR SLIME STRETCH?
Roll your slime into a cylinder shape. Hold each end of the slime with a different hand and then extend your arms. How far can it stretch before breaking?
WHAT TEXTURE IS THE SLIME?
Using a magnifying device (examples below) hold up the slime to the surface and examine its texture up close. What do you see? Does it look different when magnified?
Magnifying device examples:
- a phone camera or…
- a magnifying glass or…
- the bottom of a clear glass filled with a few millimeters of water
HOW STICKY IS THE SLIME?
Investigate the stickiness of the slime by testing it with parent approved items. Some items may include coins, buttons, beads, etc.
HOW DOES THE SLIME REACT AFTER BEING IN DIFFERENT TEMPERATURES?
Place the slime in a container near a sunny window or outside. After ten minutes, remove the slime from the container and examine it.
- Does it feel different?
- Is it warmer to touch?
- Is it more slippery?
- Is it harder to play with?
Place the slime in a container in a dark, cool location. After ten minutes, remove the slime from the container and examine. Ask yourself the same questions as above. What are some other differences you’ve noticed?
