The Toothpaste from Sheep!
Scientists in London have discovered a "woolly" new way to keep your teeth healthy! They’ve created a special toothpaste using keratin—a strong protein found in sheep's wool. When you brush with it, the keratin mixes with your saliva to create tiny crystals. These crystals actually crawl into the microscopic holes in your teeth to repair the enamel, which is the hardest part of your body. It’s like using a tiny woolly sweater to patch up your teeth!

Wee Ones
Scientists found keratin in sheep's wool, but also in bird feathers and human hair. If you have 1 pile of wool, 1 pile of feathers, and 1 pile of hair, how many piles of keratin sources do you have in total?
Little Kids
If one sheep provides enough keratin to help make 5 tubes of toothpaste, how many tubes can we make using the wool from 4 sheep? Let's count by 5s!
Big Kids
Scientists think this toothpaste will be ready to buy in 3 years. If there are 12 months in a year, how many months away is the "sheep toothpaste"?
The Sky's the Limit
A scientist needs to mix 5 grams of wool keratin with exactly 10 grams of minerals to make a small batch of toothpaste. If they want to make a giant batch using 50 grams of wool keratin, how many grams of minerals will they need to keep the ratio the same?
