  This stage of the scientific method includes taking out books from the library, going online and speaking to experts.

Conducting research/collecting information.

100

Identify and define the three types of variables in an experiment.

Independent Variable: what the scientist can control (changes)


Dependent Variable: what the scientist is measuring


Control: the part of the experiment that stays the same

Based on the graph below, what plays the largest role in helping mold grow on bread? 


Based on the graph, sugar water on bread results in the highest percentage of mold growth.

100

What step of the scientific method is this?
“If I use place the basil in direct sunlight, then it will grow higher, because basil needs a lot of sun.”

Hypothesis

200

What you think based on observations and prior knowledge (is also testable and measurable). This is also an educated guess.

Hypothesis

200

  • Create a hypothesis based on the scenario: 


     A scientist conducted an experiment to test the affect of Miracle Grow on plant heights. In Pot A, he put in the Miracle Grow. In Pot B, he did not. In both pots, he used the same amount of water, sunlight, and soil. Each day for two months, the scientist measured the height of each flower to see which grew taller. 

  • Possible Answer: 


  • If the amount of fertilizer is tested, then the plant given the most Miracle Grow will grow the tallest.

Below is a bar graph Jasmine created after conducting an experiment about paper airplanes. Based on the graph, what did Jasmine forget to include?

  • She forgot to provide the graph with a title.  

  • 10 extra points: She also forgot to label her units! (look back)

List the six steps of the scientific method, in order.

  • 1. State the problem

  • 2. Conduct Research

  • 3. Form a Hypothesis 

  • 4. Design and run the Experiment

  • 5. Analyze the data

  • 6. Draw Conclusions

300

The ___________ describes the steps you follow during an experiment.

A short statement of whether or not your results support your hypothesis is called a(n) ______________ .

  • Procedure


  • Conclusion

300

  • Identify the control, dependent and independent variable in following experiment: 


  • A scientist conducted an experiment to test the effects of Miracle Grow on plant heights. In Pot A, he put in the Miracle Grow. In Pot B, he did not. In both pots, he used the same amount of water, sunlight, and soil. Each day for two months, the scientist measured the height of each flower to see which grew taller. 

  • Control: soil, water, sunlight 

  • Dependent Variable: height of plant

  • Independent Variable: amount of miracle grow

A fifth grade student conducted an experiment to test the amount of water absorbed by different brands of paper rolls. After 24 hours, what was the difference between the heaviest and lightest brand of paper? 



  • Heaviest- Cottonelle         0.57 ounces 

  • Lightest- Angel Soft         -     0.10 ounces 

                                                    ________________

                    0. 47 ounces 

300

Describe the importance, or value, of following the scientific method when conducting an experiment.

Answers will vary.

400

What is the purpose of an experiment?

To test a hypothesis

400

  • Identify the control, dependent and independent variable in following experiment: 


  • Students of different ages were given the same puzzle to put together. They were times to see how long it took to finish each puzzle. 

  • Independent Variable: ages of the students

  • Dependent Variable: time it took to put the puzzle together 

  • Control: the same puzzle 

400

Based on the graph, between what three hours is there the greatest change in temperature? What might be affecting this drop in temperature? 



Between 2 and 5 pm there is a drop from 60 degrees to 40 degrees, a 20 degree drop in temperature. The drop in temperature may be due to the sun setting during this time.

Two students, Veronica and Jennifer did the same experiment. Veronica observed everything carefully but did not write anything down. Jennifer recorded her observations in a notebook. At the end of the experiment, each student drew a conclusion. Which student is more likely to have a correct conclusion?

Jennifer is likely to have a correct conclusion because it is based on data from the experiment.

500

  • True or False:


     Scientists repeat an experiment many times.

True!

500

  • Identify the control, dependent and independent variable in following experiment:


  • An investigation was done with an electromagnetic system made from a battery and wire wrapped around a nail. Different sizes of nails were used. The number of paper clips the electromagnet could pick up was measured. 

  • Dependent Variable: number of paper clips picked up 

  • Independent Variable: size of nails

  • Control: battery and wire 

500

With your group, create a bar graph to display the following data:


  • Student graphs will vary. 


  • Must include:


    • Title

    • Label both axis'. 

    • Include units

    • Evenly spaced bars!

 Why is it important to display results from an experiment in a chart, or graph?

It is important to display data because it will show patterns in the data.
