Scientific Method: What is Veda’s Favorite Treat?
Conducting Experiments

Students watch as Veda chooses a treat from various options.


Students will make predictions.

Students will observe and ask questions.

Students will plan and conduct a simple investigation.

Students will use simple tools and equipment to gather data.

School Therapy Dog Veda

Four paper plates with a different dog treat on each (carrot, peanut butter, dog treat, cheese whiz).

Be sure there is only one item (one dog treat, not two or three, for example) on each plate.

Pencil and paper


Have students make predictions about which will be Veda’s favorite treat. Explain why they predict that.

Place plates with treats on them throughout the room. Let Veda come into the room while students are standing back and not making noise. Students record which treat was eaten 1st, 2nd, 3rd, and 4th to see if Veda preferred one treat over the other. Repeat this 3 or 4 times. Students document each trial.

Students work through the steps of the scientific method to find out if Veda has a favorite treat.


Observe how the students are recording the data. Discuss results of the test and why they think Veda chose some treats over others. Repeat this test at several later dates to see if results change. Discuss what other food items might be used and how results might be different.
