Testing Variables in Plant Experiments

The video tutorial guides students through using the Gizmo tool for a science experiment on plant growth. It covers account setup, launching the Gizmo, and conducting an experiment by changing variables like light, soil, and water. Students are instructed to fill out a Google Doc with their hypothesis, observations, and conclusions. The tutorial emphasizes testing one variable at a time and recording results accurately.

What is the first step you need to take when accessing Gizmo?

• Download the app

• Start an experiment

• Create or log into an account

• Join a class

Which of the following is NOT a variable you can test in the Growing Plants Gizmo?

• Amount of sunlight

• Color of the pot

• Type of seed

• Type of soil

Where should you record your observations and data for the Growing Plants Gizmo?

• In a spreadsheet

• On a Google Doc

• On a piece of paper

• In a notebook

What should remain constant when testing a single variable in the experiment?

• All of the above

• The amount of water

• The type of seed

• The type of soil

What is the purpose of changing only one variable in the experiment?

• To use more resources

• To make the experiment more complex

• To isolate the effects of that variable

• To save time

What should you do after setting up the experiment in Gizmo?

• Submit the Google Doc

• Change all variables

• Hit play to start the simulation

• Turn off the computer

How long does the simulation run in the Gizmo experiment?

• 10 days

• 20 days

• 100 days

• 50 days

What conclusion can be drawn if a plant does not grow well in the experiment?

• It was the wrong type of seed

• It did not have enough light

• It had too much light

• It had too much water

Which plant showed the best growth in the experiment?

• Plant A

• All plants grew equally

• Plant B

• Plant C

What should you do if you have questions about the experiment?

• Search online
