Week 4 Science: Scientific Method

 The Scientific Method is a way to ask and answer questions about the world in a logical way. There are various versions of the scientific method floating around out there, but I think these six steps are classics. Ask a question, make observations, form a hypothesis, design and conduct an experiment, analyze your data, and draw a conclusion. The steps can be repeated as needed, and using the scientific method is a great way to learn about the world!

Why is asking questions the first part of the Scientific Method?

1

After watching the straw rocket video, write a testable question you can answer by building one or more of these straw rockets. (Example: Do longer rockets fly straighter?)

1

Form a hypothesis regarding your question.
(Example: If a straw rocket is longer, it will fly straighter because the body of the rocket will keep it straight)

 
Collect the following materials and build two or more straw rockets to test your question.  Feel free to watch the video again to see how to build them or see where you can modify them.  Remember to test in a way that you can collect measureable data (distance, height, weight, time, straigher, etc.)
Paper
Scissors
Tape
Drinking straws
Tape measure

1

Using data from two or more rockets, explain using your data if your hypothesis was correct, incorrect, or needs more testing.

1

Your friend is wondering if an ice cube has more mass before or after it melts. What would you tell her?

Put the Scientific Method order:

Draw a Conclusion
Make Observations
Form a Hypothesis
Ask a Question
Analyse Data
Conduct an Experiment

Take a picture of your two rockets and upload it here.

Say you placed a beaker of water near a window at your house and recorded the volume of water in the beaker for three weeks. What volume of liquid water was converted to water vapor that entered the air over the three week period?

1

A student places 100 grams of water and 50 grams of ice into a beaker. Which of the following is the best prediction for the mass of the contents of the beaker after the ice has melted into the water?

1

A student has a dish with a mass of 72 grams. The student places 12 grams of butter in the dish and melts the butter. Which of the following best describes the mass of the dish and butter together before and after the melting?

Good Thinking! 
See you next week!!
