Need help with this assignment!

Topic: Hot Can

I have a question, I want to know what the independent variable would be in this situation.

The purpose is to build and test a device that will keep the hot water.

The dependent variable is Temperature in Celsius.

My investigative question is: How does changing the insulators affect the temperature in Celsius?

materials that I using: cotton, cork, aluminum can, fabric, and aluminum foil

Topic: Cold Can

The purpose of this is to cool hot water as fast as possible

My investigative question is: How does changing the shape of the can affect the temperature in Celsius?

I want to know what the independent variable would be in this situation. What is the independent variable in this experiment? and hypothesis!

The dependent variable is: The temperature in Celsius

Hypothesis : (if (IV affects DV). Then (list the materials you are using or what you did to the can and predict what will happen to the temperature) Because (explain the science/what we have learned about conductors)

Materials: aluminum can, hot glue sticks

Data table for the Hot Can / Cold Can" challenge

DATA TABLE FOR THE "HOT CAN" / "COLD CAN" CHALLE Directions: 1. Record the starting temperature for the Hot Can, Control Can, and the Cold Can (O minute). 2. Record data for EACH can every minute for 20 minutes. HOT CAN CONTROL CAN COLD CAN Time Temperature Time Temperature Time Temperature (minutes) (C) (minutes) .
