This is always kept constant or the same in an experiment
This is a summary of data usually displayed in a graph
This is the information you gather from an experiment. It can be numbers or observations. We usually record it in a chart during the lab
This is the end of a lab where you write your results for the lab
A Variable that you change in your experiment
A type of observation that is expressed by the five senses; you can see, touch, hear, smell, or taste it (ex. The shirt is black)
A Variable that changes depending on what is done in the experiment
Part B: Look at the picture and write two observations and one inference about it.
Part C: Short Answer:
SpongeBob loves to garden and wants to grow lots of pink flowers for his pal Sandy. He bought a special Flower Power fertilizer to see if will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilized water. He places the other plant on a shelf in a closet and waters it with plain water every other day.
10. What did SpongeBob do wrong in this experiment? Explain.
11. If the experiment is done correctly what types of things need to be kept constant?
12. What is the independent variable?
13. What is the dependent variable?
