Which of the following is NOT a testable question? A) Does water temperature has an effect on plant growth? B) Will lavender plants fed with apple juice have a more pleasant aroma? C) Does brushing with baking soda make teeth whiter than brushing with toothpaste? D) Do different foods mold/spoil at different rates?
B) 'more pleasant aroma' is an opinion. Scientific experiments are based on fact.

**Why is the Earth heated unevenly?
Because the Sun's rays strike the Earth at different angles.

**Describe the digestive process.
Teeth break down food --> food travels down esophagus to stomach where it mixes with acid and is broken down further ---> small intestine where nutrients are absorbed ---> large intestine where water is absorbed ---> waste matter expelled.

**Describe the water cycle.
Water evaporates, condenses in clouds, clouds get full of water, precipitation occurs.

**Ms. Moore wanted to see how quickly various solutions evaporated. She made a salt-water solution, a sugar water solution and a citric acid solution. She used 5 cc of dry material and 50 ml of water for each solution. Each solution was mixed in identical containers. She put one solution by the window, another solution was put on the desk, and the last solution was put in the closet. She observed the results daily. Is this a reliable experiment? Explain your answer.
It is not a reliable experiment because there are two independent variables (type of solutions and the locations where she put the solutions to evaporate). An experiment should only have ONE independent variable.

What is water vapor that can be seen called?
