Keeping Our Teeth Healthy

Lately, we have been learning how and why it is important to take care of our teeth! After reading many books and watching some short videos, we came up with ways to keep our teeth healthy.

We need to:

- Brush our teeth two times a day

- Floss our teeth once a day

- Visit the dentist

- Eat lots of healthy foods

- Do not eat too many treats

- Drink milk or water

- Wear a mouth guard when playing sports

- Replace our toothbrush often

- Do not chew on hard items such as markers, toys, etc.

Last week, we did another fun experiment together! Ms. Petersen had four hard-boiled eggs. These hard-boiled eggs represented our teeth! We put each egg in a different kind of liquid.

Here were some of our predictions:

Water	- The egg might break - Might turn brown
Milk	- Might break into two pieces - Egg might disappear
Vinegar	- The bubbles will explode - There will be no more bubbles
Pop	- Egg might turn different shades of brown and black

After we waited two sleeps, we took the eggs out of the liquids. We are getting so good at observing and noticing all kinds of different things during our experiments!

Here were some of our observations:

Water	- There was a little bit of brown on the egg but mostly white - Pretty strong - It was shiny
Milk	- Very strong - White in colour - Did not break - It was shiny
Vinegar	- The bubbles stayed on the egg - The shell disappeared and the egg was soft - White in colour
Pop	- Turned brown - We couldn’t brush off the brown with a toothbrush

 

Then we had to choose 2 of the experiments to draw on our recording sheet. Notice how we used our best listening ears to hear the sound of the words! Then we had to describe to Ms. Petersen what would happen to our own teeth if we drank that particular kind of liquid. Since we have started doing experiments in our classroom, we are starting to apply our new-found knowledge to our world around us.

Ask me what will happen to my teeth if I drink one of the above liquids!

Needs and Wants

Over the last two  weeks, we have been learning about things that we NEED to survive. At first, we thought we needed many things to live. These things included:

• A car
• Bones
• Blood
• A computer
• Food
• A house
• TV
• Clothes
• Brain
• Water
• Milk
• Among other things

Then we watched a video that explained that there are 5 (basic) things that we NEED in order to survive. We need:

1. Air
2. Healthy food
3. Shelter (a place to live)
4. Water
5. Clothes

     

     We had many discussions about other things that students thought we needed. The biggest thing was a car. Many students thought that we NEEDED a car to live. We brainstormed some ways we could get to school if we didn`t have a car. We thought that we could walk, take a bus, take a taxi, ask a friend to drive us, take a plane or train. It was very hard for some of us to imagine our life without a car!

 

We also thought a lot about the things that we want. This book explained that both adults and kids have to make tough decisions sometimes to buy only things that they need. In the book, Dad really wanted to buy root beer, but decided to leave it at the store and get healthy food instead. Sometimes we are lucky and we are able to get the things that we want, but only after all of our needs have been met. We watched this video to help us understand that we shouldn`t ask for so many things that we WANT but don`t need.

We also sorted the following pictures into two categories: Wants and Needs.

Ask your child to tell you the 5 things we NEED to survive and a few things that they want!
