Where Can I Get Animal Teeth For Science Project

This fun tooth disuse experiment with egg shells is all about teeth and how to proceed them healthy. First nosotros talked nigh how of import it is to brush teeth everyday and and so chatted nigh foods that are good for teeth and foods that aren't.

Sugary, viscous food is not good for teeth as it sticks to the surface, bacteria then break down the sugar to make acid which can harm teeth.

Did yous know eating cheese at the end of a meal can assist neutralise the acids in your rima oris and reduce the chance of tooth disuse?

Molar Disuse Demonstration

We used these giant teeth from The Consortium and some play dough to demonstrate plaque building upwards on teeth. The giant teeth made a great prop and actually kept the children engaged for a long time.

The we fabricated models of our mouth using more play dough, talking nigh the size and shape of teeth in our jaw.

Molar decay experiment with egg shells

Nosotros tin can't experiment on our own teeth so are using eggs to represent them, as the shell of an egg is made of a similar substance to tooth enamel!

What y'all'll demand for a tooth decay experiment:

Eggs

Jars

Water

Tea/Java

Fizzy flavoured drink

Vinegar

Toothpaste

Instructions

• Pour the same amount of fizzy drink, vinegar, water and tea or coffee into your jars.
• Add a whole raw egg nonetheless in it'south shell to each, cover an actress egg with toothpaste and besides identify in tea/coffee.
• Leave for approximately iii days.
• Remove the eggs.
• Rinse the egg kept in vinegar and rub gently until the beat comes away.

Results of our tooth decay experiment with egg shells

You lot should see staining on both the fizzy drink and tea/coffee egg.

We institute our toothpaste covered egg stained less than the non toothpaste covered egg.

The vinegar completely dissolved the eggshell, leaving just the membrane behind.

Why do teeth stain?

Tea is rich in tannins which stain teeth if they're not cleaned properly while cola and fizzy drinks are acidic as well as containing staining products.

Vinegar ( which is acidic)  dissolves the calcium carbonate in the beat out, leaving simply the membrane intact. This very cool egg experiment lets yous bounce an egg without it breaking!

More than egg experiments for kids

Did you know you can make a potent bridge from eggshells?

Walk on raw eggs like Housing a Woods.

Make a model rima oris using biscuits, marshmallows, jam and peanut butter. This disgusting action is one of threescore Gross Science Experiments y'all can find in my latest volume, GROSS Science.

Or, how about trying one of my other very eggy experiments!!

Egg Experiments

Actress background information for KS1 and KS2 Science

Teeth are non but for eating, animals often use them to defend themselves or to attack other animals.

Different shaped teeth have different purposes. Apartment molars like humans have are for grinding and chewing nutrient, while abrupt canine teeth are for tearing food apart ( these are found in carnivores ) and large incisors for cut and chopping grass ( found in herbivores ).

Caring for teeth

Cleaning teeth, using floss and mouthwash aid keep teeth and gums free from plaque. Plaque is formed by bacteria feeding on the sugar left on the surface of teeth afterwards eating.

Suitable for Early Years Foundation Phase

Concrete Development → Health and self-intendance → ELG

• Children know the importance for good health of concrete exercise, and a salubrious diet, and talk about ways to go along good for you and safe. They manage their own bones hygiene and personal needs successfully, including dressing and going to the toilet independently.

Key Stage ii – teeth exam

Describe the importance for humans of do, eating the right amounts of different types of food, and hygiene.
