EiE Video Snippets: NGSS Science and Engineering Practices

Practice 3: Planning and Carrying Out Investigations

Young engineers test their designs by conducting experiments. They identify relevant variables and decide how they will be measured, and they collect data for analysis.

What makes the best mortar for a wall? Students reflect on their testing of some materials and their properties.  

Predicting, testing, observing, and comparing: elementary engineering is closely connected to inquiry-based science.

When team members share ideas, the group is more likely to come up with a good design for a hand pollinator.

You’re going to make a device for pollinating flowers by hand. What will it look like? What materials can you use?

Struggling with new ideas encourages students to explain their reasoning.

An accident in the data collection process provides a chance for learning.

The class discusses variations in temperature data.
