Six Characteristics of all living things:
1. Have one or more cells
2. Have DNA
3. Use energy to carry out activities
4. Reproduces
5. Grows and develops
6. Senses and responds to change
Four Necessities of all living things:

Scientific Method: The steps used to solve a problem
7 steps
1. Identify the problem- a clear statement of the question to be answered
2. State a hypothesis – a suggested solution to a problem.
3. Test the hypothesis – design an experiment to investigate the problem
4. Make observations – Keep records of all data collected.
5. Analyze Data – organize data and find the meaning of it.
6. State a conclusion – Explain the data. Do your results support the hypothesis?
7. Share your results.
Vocabulary:
Hypothesis: an educated guess or a suggested outcome for the experiment
Constant: Something that remains the same during an experiment
Variable: Something that changes during the experiment
Independent variable: The one thing you are changing to test the outcome. (amount of sunlight)
Dependent variable: The measure of the change. (plant growth)
Observation: Information gathered during an experiment using the senses.
Inference: A conclusion based on observations or from given information.
Data: The information gathered by observation

C) 4.6 L to mL
Which is larger? A) 550 mm or 1.5 m
B) 3.2 L or 4000 mL
C) 5000 g or 1.2 kg
Which is smaller? A) 12 mm or 1 cm
B) 600 mL or 2 L
C) 3.5 g or 350 mg
