Properties of Water
The name of the bonds holding together ONE MOLECULE of water
What is Polar Covalent Bond
The first step of the scientific method.
What is making observations?
The factor that you measure or the outcome in an experiment.
What is the dependent variable?
Plants take in carbon dioxide during this process.
What is photosynthesis?
Using natural resources carefully so they are available in the future.
What is sustainable development?
This property allows insects to walk on water
What is Surface Tension
An educated guess based on observations is called this.
What is a hypothesis?
The factor you deliberately change.
What is the independent variable?
Which part of the water cycle moves water from plants to the air?
What is transpiration?
These resources can be replaced naturally within a human lifetime.
What are renewable resources?
Water molecules stick to each other because of these weak bonds
What are hydrogen bonds?
After forming a hypothesis, this step tests it.
What is conducting an experiment?
A group used as a baseline comparison.
What is the control group?
Nitrogen gas must undergo this process before plants can use it.
What is nitrogen fixation?
Why do environmental scientists collect data after a solution is applied?
To see if the solution works or needs to be modified.
This property keeps Jax Beach temperatures from fluctuating too much
What is high specific heat?
Why is replication important in science?
It increases reliability of results.
These must remain the same throughout the experiment.
What are constants or Controls?
This bacteria changes NH3 (ammonia) into NO3- (nitrate)
What is Nitrifying Bacteria?
Give one example of a renewable resource.
Water, sunlight, wind, forests (any one)
This property makes water the “universal solvent.”
What is polarity?
A scientist plans to study organisms that live in hot springs. What should be the first step in the investigation?
What is recording observations about the organisms?
A student wants to test how different amounts of sunlight affect the growth of bean plants. Using the hypothesis formula (If…, then… because…), write a hypothesis for this experiment.
What is: If bean plants are placed in more sunlight, then they will grow taller because sunlight provides the energy needed for photosynthesis.
Burning fossil fuels increases the amount of carbon dioxide in the atmosphere. Which process in the carbon cycle can help reduce this increase, and why?
What is: Photosynthesis, because plants take in carbon dioxide and convert it into food.
Give one example of how humans negatively impact natural cycles.
Burning fossil fuels → increases CO₂.
