AT Cycle 6

❤️ 1: F 10/9a, 💛 3: F 10/9  ladder lab (1)

Today, we'll use the materials from the Torque Meterstick Lab again to investigate the situation of a ladder leaning against a wall.  We'll start with a short video about ladder safety.  We'll use this to generate some questions about ladder safety.  We'll use what we know about static equilibrium to figure out where we can stand on a ladder and feel safe.  You will work as collaborative team members to build a couple different models of the situation and make predictions about safety.  Then, we'll test your Ladder Lab models with a few questions.  We'll use the materials from the previous lab to try to test your predictions in this lab.  You'll go through the iterative process of engineering your ladder model to correct any weaknesses.  You'll answer a few more questions to make sure your model works well.  Finally, you'll answer the ultimate question about the real-life safety of ladders by researching some specifications of real ladders and you'll consider some design choices that could make the ladder safer.    

Handout:  Ladder Lab 

Homework:  Finish creating your mathematical models on page 1 of Ladder Lab if you have not already done so.  We will test your models next time.
