Bubble measurement is a test which can prove that pond weed produces oxygen gas. Pond weed releases oxygen and takes in carbon dioxide during the process of photosynthesis. The experimenter will find the outward-moving bubbles containing oxygen with which to oxygenate the plant in question's surrounding water.
glowing splint ... if it relights then the chemical reaction produces oxygen.
The dissolved oxygen level in pond water can vary depending on factors such as temperature, aeration, and biological activity. Generally, a healthy pond should have dissolved oxygen levels above 5 mg/L to support aquatic life. Testing the water with a dissolved oxygen probe or chemical test kit can provide an accurate measurement.
Pond fish may be dying due to poor water quality, overfeeding, or lack of oxygen. To prevent this, regularly test water quality, avoid overfeeding, and provide adequate aeration and filtration in the pond.
You can test for the presence of oxygen gas by using a glowing splint test. A glowing splint will reignite in the presence of oxygen. Alternatively, you can use a chemical reaction like the decomposition of hydrogen peroxide, which produces oxygen gas bubbles. Additionally, you can use an oxygen gas sensor to directly measure the presence of oxygen in the air.
One way to test if a gas is oxygen is by using a glowing splint test. A glowing splint placed in a test tube of the gas will reignite if the gas is oxygen. Another method is to use a colorimetric test strip specifically designed to detect oxygen, which will change color in the presence of oxygen gas.
This is a simple test that uses a specific chemical to react to the presence of oxygen in the water. An indicator is often added as well, so that depending on the level of oxygen there is a color change that can be measured against a standard reading chart provided with the test kit. You can purchase these kits at most pool stores.

A blood test can prove many illnessed or diseases you may have, and tell how much iron and minerals are in your body.

The chemical test for oxygen is the glowing splint test. In this test, a glowing splint is extinguished in the presence of oxygen due to its ability to support combustion. If the splint reignites, it indicates the absence of oxygen.
It's not a sobriety test, it's meant to prove that you are intoxicated, not prove your sobriety. If you deny your field sobriety test or breathalyzer you can get your license suspended.
