Question

objective
understand the nature of science

• devised that scientific investigation may or may not use the same set of procedures, determined that there is not just one “scientific method”
• science findings are based upon evidence

1. maria grew bacteria from the mouth on special plates in the laboratory. the plates were of different temperatures to bacteria growth rate.
2. eddie used a survey to determine how many other classmates were left - handed and how many were right - handed.
3. joey saw cockroaches come out after dark. he asked, “how do bugs find the corners in the hall?”
4. james wondered if grass could be grown out of plant leaves, flowers, and stems.
5. mike soaked six different kinds of seeds in water for 24 hours. then he planted the seeds in soil at a depth of 1 cm. he used the same amount of water, light, and heat for each kind of seed.
6. al read about growing plants in water. he wanted to know how plants could grow without soil.
7. lewis said, “if i grow five seedlings toward light, i think the plants will grow faster than the five plants grown in white light.”
8. angela’s experiment proved that earthworms move away from light.
9. brent said, “if i feed ten different plants in a particular lake, it might affect small animals, such as crayfish, that live in the same water.”
10. michael fed different diets to three groups of guinea pigs. his experiments showed that guinea pigs need vitamin c and protein in their diets.
11. kim’s experiment showed that children’s eggshells were stronger when she gave her hens feed, to which extra calcium had been added.

1. draw conclusions

a. recognize a problem
b. form a hypothesis
c. test the hypothesis with an experiment
d. draw conclusions

dinosaur scene - observation and inference worksheet

1. the dinosaur is sneezing.

a. observations
b. inferences

1. the carnivorousness is going to eat the stegosaurus.

a. observations
b. inferences

Explanation:

Part 1: Scientific Method Matching (Questions 1 - 10)

Question 1

• Brief Explanations: Analyzing data (counting left/right - handed) to draw conclusions about the class. This is drawing conclusions from results.
• Answer: D. Draw conclusions

Question 2

• Brief Explanations: Asking a question about how the color of the room affects mood is recognizing a problem to investigate.
• Answer: A. Recognize a problem

Question 3

• Brief Explanations: Wondering if juice can be extracted from plant parts is forming a question - based hypothesis (a tentative idea to test).
• Answer: B. Form a hypothesis

Question 4

• Brief Explanations: Soaking seeds, planting, and using the same water/light/soil is conducting an experiment to test something (implied hypothesis about seeds).
• Answer: C. Test the hypothesis with an experiment

Question 5

• Brief Explanations: Being curious about growing plants in water and how they grow without soil is recognizing a problem to study.
• Answer: A. Recognize a problem

Question 6

• Brief Explanations: Making a statement about how plants will grow (comparing to a first plant) is forming a hypothesis (a prediction).
• Answer: B. Form a hypothesis

Question 7

• Brief Explanations: A conclusion is drawn from Anabela’s experiment about sunflowers moving from light.
• Answer: D. Draw conclusions

Question 8

• Brief Explanations: Making a prediction about what will happen when two plants are in the same water is forming a hypothesis.
• Answer: B. Form a hypothesis

Question 9

• Brief Explanations: Michael’s experiment (feeding different diets) leads to a conclusion about guinea pigs’ needs.
• Answer: D. Draw conclusions

Question 10

• Brief Explanations: Kim’s experiment results lead to a conclusion about eggshell strength and calcium.
• Answer: D. Draw conclusions

Part 2: Observation and Inference (Questions 1 - 2)

Question 1

• Brief Explanations: “The dinosaur is sneezing” is a direct observation of what is seen in the picture.
• Answer: A. Observations

Question 2

• Brief Explanations: “The carnivorous is going to eat the stegosaurus” is an inference (a conclusion based on observation, not a direct observation).
• Answer: B. Inferences
