In this Remarkable Idea students will learn about and use the Scientific Method to conduct an experiment involving colors.
This activity addresses:
- Choice making
- Social skills
- Cause and effect
- Alternative methods of access
What you need:
- All-Turn-It Spinner
- Blue2 Bluetooth switch
- Ice cube tray
- Clear cups or jars
- Food coloring (red, blue, yellow)
- Dye water with the red, blue, and yellow food coloring, place into ice cube trays, and freeze. At least four of each color will be needed.
- Write your vocabulary words in a place where all students can see them.
- Record definitions of “hypothesis” and “conclusion” to TalkingBrix.
- Record the colors purple, green, and orange onto the Step-by-Step.
- Record the steps of the scientific method onto a Step-by-Step.
- Ask a question
- Construct a hypothesis
- Test with an experiment
- Analyze data and draw a conclusion
- Communicate the results
What to do:
- Have a student activate the a Step-by-Step to share the steps of the scientific method with the class so you can discuss them. When you come to one of the vocabulary words, have your “Word Whiz” define them using the TalkingBrix.
- One student can be assigned the extra duty of “Lab Assistant” to take photos of the experiment in progress with the camera app on an iPad/iPod using a Blue2 Bluetooth switch. The resulting pictures could be made into a bulletin board with the results of the experiment so students can present their findings with more people.
- Allow students to choose a hypothesis using the All-Turn-It Spinner and complete a hypothesis using the Step-by-Step:
- When the yellow cubes melt and mix with the blue cubes, I hypothesize the water will turn the color ___________.
- When the blue cubes melt and mix with the red cubes, I hypothesize the water will turn the color ___________.
- When the red cubes melt and mix with the yellow cubes, I hypothesize the water will turn the color ___________.
- To add another level of difficulty, use different amounts of ice cubes in cups or all colors and challenge students to think about what will happen with those cups.
- Another fun addition would be to create a time-lapse video of the ice cubes melting. This can be done with an iPad with iOS 8 or digital cameras.
