Im doimg a STEM Project on natural substances for teeth whitening these are materials and steps:
Materials:
1. Baking soda
2. Lemon juice
3. Coconut oil
4. Activated charcoal
5. Toothbrush
6. Mixing bowl
7. Measuring spoons
8. Timer or stopwatch
9. Optional: toothpaste for comparison
Steps:
1. In a mixing bowl, combine 1 teaspoon of baking soda with a few drops of lemon juice.
2. Mix well until it forms a paste-like consistency.
3. Dip your toothbrush into the mixture and gently brush your teeth for 2 minutes.
4. Spit out the mixture and rinse your mouth thoroughly.
5. Optionally, you can also try brushing with coconut oil or using activated charcoal for additional whitening effects.
6. Repeat this process 2-3 times a week for a few weeks and see how it works for you.
What can I put Data/Observations on?
It is easier to understand the data if it is put into a table or graph.
Create a table first that organizes your data.
Make sure the table has a title and data is clearly identified.
Make sure any numbers have units (SI).
Create a graph and import it here (or on an additional slide).
This can be a line graph, bar graph or pie chart (depending on what kind of data you have.
Make sure all data is properly labeled.
Is there a title?
Is there an x-axis/y-axis? What values should be there?
Did you use TAILS (title, axis identified, intervals (spaced out properly), labels, scale (does the graph fit the entire page)?
Is there a legend or a key?
The data/observations for your STEM project on natural substances for teeth whitening can include the following:
1. Initial teeth shade: Before starting the project, record the shade of your teeth using a shade guide or any other method of measuring teeth color.
2. Treatment duration: Record the number of weeks or days you have been following the whitening process.
3. Teeth shade after each treatment: After each treatment, record the shade of your teeth again using the same method as the initial measurement.
4. Comparison with toothpaste: If you are using toothpaste for comparison, record the shade of your teeth after using toothpaste for the same duration as the natural substances.
You can organize this data in a table like the following:
| Treatment Duration (weeks) | Baking Soda & Lemon Juice Teeth Shade | Coconut Oil Teeth Shade | Activated Charcoal Teeth Shade | Toothpaste Teeth Shade |
|----------------------------|---------------------------------------|------------------------|-------------------------------|-----------------------|
| 1 | | | | |
| 2 | | | | |
| 3 | | | | |
For the graph, you can create a line graph with the treatment duration on the x-axis and the teeth shade on the y-axis. The values on the y-axis can correspond to the shade guide used (e.g., 1-10 scale), and the x-axis values will be the duration of the treatments. Make sure the graph has a title, labeled axes, proper intervals, and a legend/key if needed.
It is important to note that natural teeth whitening methods may have varying effects on different individuals, and the effectiveness and results can differ. Therefore, conducting this project on multiple participants and averaging the data may provide more reliable conclusions.
