  1. Science Exam Study Guide

  2. What are the six parts of the scientific method (in order)? • Observation • Hypothesis • Experiment • Data collection • Conclusion • Retest

  3. What are the 3 types of variables in an experiment? • Control • Independent • Dependent

  4. What is a procedure to test the hypothesis? • Experiment

  5. Which one of the steps is gathered through your senses? • Observation

  6. In our floating cans experiment: • What was the control variable? • The can of coke • What type of data did we collect? • Qualitative • What was the independent variable? • The different cans of soda

  7. Who was the man who first studied cells? • Robert Hooke

  8. What is a clear, jelly-like substance that holds the organelles in the cell? • Cytoplasm

  9. What is the stiff outer layer that gives plant cells their shape? • Cell Wall

  10. What is in charge of making protein? • Ribosomes

  11. What surrounds and protects the nucleus? • Nuclear Membrane

  12. What is in charge of what enters and leaves the cell? • Cell Membrane

  13. What is found only in plant cells and allows the plant to make food? • Chloroplast

  14. What is the control center of a cell? • Nucleus

  15. Define these words: • Tissue – specialized cells with similar structure and function. • Organ – a structure made up of at least two types of tissues that work together to perform a specific job. • System – a group of organs that work together to perform a specific function.

  16. What are the jobs of the digestive system? • To digest food • To transfer digested nutrients into the blood • To absorb water

  17. List the steps of how tissues help your hand move when you touch a hot stove. • Nerves in your hand send a message to the spinal cord. A reflex takes place when nerves in the spinal cord send signals to muscles in your hand that cause you to move it off the stove. Then, the nerves send a message up the spinal cord, where the brain receives it.

  18. What kind of tissue is blood? • Connective tissue

  19. What kind of tissue gives an organism the ability to move? • Muscle tissue

  20. What kind of tissue are villi? • Epithelial tissue

  21. What kind of tissue gives an organism the ability to respond to stimuli in the environment • Nerve tissue

  22. Describe the levels of organization from cells to organ systems • Cells make up tissue, tissue make up organs, and organs make up organ systems.

  23. What are the four kinds of tissues? • Epithelial • Connective • Muscle • Nerve

  24. What do organs have in common? • They are all made up of the four kinds of tissue.

  25. Why is the heart made up mostly of muscle tissue? • The heart requires muscle tissue to keep beating.
