Grades 3-8

Inquiry Challenges:

This section will provide you with ideas students can use to practice inquiry. The Oregon Science Standards provides the following format for Inquiry.

• FORMING THE QUESTION/HYPOTHESIS

• DESIGNING THE INVESTIGATION

• COLLECTING AND PRESENTING DATA

• ANALYZING AND INTERPRETING RESULTS

You will need to judge at what level your students are able to enter the format. The ideas presented will give more information than the students should be given but will help you direct their activities.

Procedure in the following refers to directions for the teachers only. Students are encouraged to apply the various steps of inquiry and teachers need to help them with the steps with the Inquiry steps.

HOUSE DRAFTS

Procedure: Show the students a draftometer you have constructed using the following design.

Materials: Pencil, Tape, Plastic Food Wrap

QUESTIONS:

Which are the biggest sources of air? Windows… Doors…Electrical outlets…. Others

How does a fireplace change air movements in a house?

Does the presence of dirt around doors and windows correlate with air movement?

COLORED WATER

Procedure: Raise the question does color of water or the water container has anything to do with the ability of water to retain heat?

Materials: Juice cans, Food Color, Thermometer, Hot water, Spray Paint

Students might take this inquiry in two different ways. First they might make different colored waters and test their ability to retain heat. Second they might paint the juice cans different colors and test them. Either way will give them opportunity to practice Inquiry.

COVERED OR UNCOVERED PANS

Procedure: Challenge students with question,” Will water boil faster in a covered pan than in an open pan?”

Materials: Pan with lid, Heat source (hot plate), Stopwatch, Water, Thermometers

Remember to caution students about heated water and hot plate burners. Are there controls to this experiment that will make for different testing procedures. An example might be to have students start with the burner on before placing the pan on to heat.

Additional Challenges

Galvanometer

What happens when the Electo magnet and the Galvanometer come into range of each other?

Electomagnet

How do more wire wraps change the strength of the electromagnet?
