Each lab group in your class is given a skateboard and is challenged with making the skateboard roll faster than it currently does. The team that can make their skateboard move the fastest down a ramp will win a prize! You group decides that you are going to test the impact of a few different factors like changing the wheel type, using a lubricant on the wheel axles, and adding weight to the top of the board. You run each of these experiments independently to see if they positively impact the speed of the board. Which of the “Eight Practices in Science and Engineering” is this an example of?
1. Making an evidence-based argument
2. Asking questions and defining problems
3. Obtaining, evaluating, and communicating information
4. Planning and carrying out investigations
