This unit has seven lessons complete with lesson plans so it is easy to incorporate them into your plans. Although the lessons are actually designed for grades 7 and 8, they are easy to use in high school especially since instruction has been hit and miss over the past couple of years due to the pandemic.
The first lesson explores graphs with the same data but appear different due to the different scales being used. The activity goes through several pairs of graphs that contain the same data but with different markings on the y-axis so the whole graph looks different somewhat before asking students to draw graphs using different units to see how things change or to look, really look at graphs that look the same but are on two different topics such as water levels and student enrollment. There are 14 slides including an introduction and a summary. Furthermore, the lesson plans offer a set of worksheets students can fill out to show what they learned.
The second lesson is on interpolation of values from the experimental data on chirping crickets. The values students come up with are used to create a linear equation. Lesson three has students learning more about independent and dependent variables while discussing things such as taking a 19 day trip and trying to identify whether milage or day is independent. The fourth lesson has students matching graphs to the word story provided. This begins with a story about someone who took a glass of iced coffee from the fridge and microwaved it to get it hot enough to drink but it takes him several tries. This is good because it breaks the story into pieces which are matched to the appropriate part of the graph before the student has to choose the whole graph.
The fifth lesson has students analyzing graphs related to Hurricane Katrina and the damage it did to New Orleans. It looks at distance from New Orleans, wind speed, barometric pressure and how the wind speed and barometric pressure relate to each other. The sixth lesson explores the growth rate of American boys and girls from ages two to 20. It has students looking at finding an average growth rate so they can create a linear graph. The final lesson is on population growth and break points. It has students learn about the S-curve or logistic curve so they can see how everything they've learned applies. They get to use what they learned about the logistic curve to create an experiment on the population growth of duckweed.
As stated before all lesson plans come with lesson plans and most lessons average about 15 slides. What I like is that if a student misses a question, the program breaks down the steps even further or explains more about things until the student gets the correct answer and they cannot move on till they get the correct answer. This unit could be used in either math or science and I think it is nicely done. Check it out to see what you think. Let me know what you think, I'd love to hear. have a great day.
