An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, what is the dependent variable?

• Type of plant

• Water, apple juice, milk

• Plant growth

• Color of the plant's leaves

If a student is doing an experiment to see if plants will grow in different types of soil, what should be a constant?

• type of soil

• who the person is measuring it

• Location of the Plant

• Temperature of the room

• The type of soil

Investigate how changes in matter at the molecular level can lead to the development of new materials with specific properties.

• Design an experiment to create a new polymer by combining different monomers and testing the material's properties, such as strength, flexibility, and resistance to heat.

• Mix various liquids to observe color changes without considering molecular structure.

• Freeze and melt different substances to see which one lasts longer in its solid state.

• Observe the solubility of different salts in water without altering their molecular structure.

DOK Level 4: Extended Thinking

Design a project to compare the effects of physical changes (such as temperature and pressure) on different states of matter.

• Heat and cool water, ice, and steam to observe changes in state and record temperatures at which these changes occur.

• Freeze and melt different metals to see which one has the highest melting point.

• Apply pressure to various solids to determine their hardness.

• Observe the color changes in substances when heated without measuring temperature.

What is an experimental group?

• A group of students who are excited to do their science fair projects

• The group that is exposed to the independent variable

• The group that is finding the dependent variable

• The person that does the experiment

What is a control group?

• The students who wait till the last minute to do their experiment

• They tell everyone what to do

• You have to give exact instructions

• A group that does not receive 'treatment' in an experiment (you can only have this with people experiments!)

Marcos wants to know: Does the type of gasoline put in a car effect how fast the car can drive? What is the independent variable?

• Type of gasoline

• which car the gas is put into

• how fast the car can drive

• how much gas is put into the car
