A
What do you write in a hypothesis
A description of what you think will happen during the experiment
What shape is a cornstarch particle
Long and thin oval like shape
What is the pH range of an acid
0-7pH
What is the first step of the water cycle
Evaporation
Example of a gas is
Will assess depending on the answer
What do you write in a conclusion
What actually happened (the results of the experiment) and why it happened + why your hypothesis was either wrong or correct.
Oobleck turns watery when force is applied, and turns hard when no force is applied. True or false
False. It is the other way around
What is the symbol/ letter for the chemical "Oxygen"
O
What is a solute
The thing that is being dissolved
What is the 4th step of the water cycle
Collection
Everything is made out of
Atom
What is a state of matter that has its own shape, and its particles are really close to each other that it is vibrating the whole time?
Solid
What is the full name of "pH"
Potential of Hydrogen
When something is supersaturated, it...
cannot dissolve anymore of the solid/ solute
What is the right order of the water cycle
Evaporation -> Condensation -> Precipitation -> Collection
What is the thing that tells us how acidic or basic something is? (can be made out of red cabbages)
Universal indicator
What is a state of matter that does not have its own shape, can become the shape of its container, and the particles of it are neither too close nor far from each other?
Liquid
What is the pH based on
Concentration of Hydrogen ions
What is a concentration?
How much something is inside of something
Capillary action is the process of
water being brought/ transported to the leaves from the roots through the xylem
What should a good method include (state one)
- measurements of how much of each materials will be used
- easy to understand and clear step by step process
- safety precautions
- Step by step explanation to how the experiment should be cleaned
- How to measure the results of the experiment
What is the name of a tube in a plant stem that transports/ brings water from the roots to the leaves? (goes up)
Xylem
Greater concentration of hydrogen ions is a/an (base or acid)
Acid
What does OH- stand for
Hydroxide (Hydrogen + Oxygen)
In our rock candy experiment, when the water evaporates in the sugar water, the sugar is separated from the water. After that, the separated sugar sticks onto the chopstick, creating salt crystals. (True or False)
False: creates sugar crystals not salt crystals.
