4th Grade Basic Principles Laboratory (by date, latest first)

Use this hands-on scientific method activity during a matter unit, or as a fun science center. Perfect for some fun after break!

You will need:

- a clear jar (such as a mason jar)

- 2 cups of water

- 2 tablespoons baking soda

- 6 tablespoons white vinegar

- food coloring (optional)

The question and procedure is filled in on the recording sheet. Students will need to formulate and record their hypothesis, materials, observations, and conclusion. There are guiding questions to help students think about what happened during the experiment.

The reaction created by the mixture of the baking soda and vinegar causes CO2 to form, creating gas bubbles that make the corn "hop" around.

I welcome and appreciate your comments! :)

This scientific method can be used for any grade! It helps students work through a note taking process and practice putting the scientific method in order for the steps and through examples. Students can also create their own experiment to practice putting the steps in order!

This is great for visual, auditory, and kinesthetic learners! After this, students can create and practice these steps through an experiment!

What's included:

• Guided Notes
• Vocabulary Words with visuals, definitions, and vocabulary
• Scientific Method Practice
• Scientific Method Review
• Experiment Creator Steps
• Answer Key

Students will use a chair, a board and car with interchangeable wheels (like a LEGO or K-Nex car) to examine the affects of the inclined plane. Students will run experiments, collect data, and do mathematical calculations including mechanical advantage to complete the activity.
