This is a science lesson plan for a fourth grade lesson that touches on the topic of Mechanical weather. This lesson includes an introduction to the material where students are able to connect prior knowledge to the theme of Mechanical Weathering through a large group discusion about peanuts. Then the students will be going through a powerpoint presentation that further explains the concept of mechanical weathering. Then I will demonstrate an example of mechanical weathering while the students do the following :
Make observations about the chalk before beginning the activity. Have students sketch the chalk and predict what will happen when it is shaken in a plastic container with salt for two minutes.
Place a teaspoon of salt in a plastic container with a small piece of sidewalk chalk.
Set a timer and place the lid securely on the container.
Shake for two minutes.
Observe the chalk after shaking and compare it to the chalk before it was shaken with salt.
Discuss how this is like weathering.
Then the students will get the opportunity to perform their own experiment surrounding mechanical weathering.
I would briefly talk about why it is important to me to think about how this lesson might be adapted for different schools or classroom communities.
In terms of this lesson, there are a few different ways that I would make adjustments to better fit for different schools or classroom communities. One adaptation I would make is to create different forms of assessments at the end of the lesson. In the original plan, I had students completing an exit ticket to help show me which students grasped the concept and which students may need some more extra support. This does not fit with the wide variety of learners i would have in my classroom, So one way i would change this is to
1)have both a physical and digital form of the exit ticket
2)rework the activity so that it is less of an assessment and more of a demonstration of knowledge
