Math Lab: Investigating Second-hand Smoke Using Inequality Symbols
This lab is great to use as reinforcement to newly learned lessons, or it can be used as a semester review! Honestly, this is one of my favorites! * Working with a partner, students use balloons to measure the volume of a single breath of air and apply their calculations to determine (mathematically) how much second-hand smoke they breathe when exposed! * In the process of making their discovery, students use the circumference formula in a variety of forms in order to find a radius, and ultimat

Linear and quadratic functions - performance task
This is a media-based performance task. It requires that students watch a YouTube video which will engage them in answering the questions in the handout. More importantly, students will increase their understanding of linear vs. quadratic functions by evaluating functions for various points. They will also make a connection about how the degree of the function determines the shape of its graph.

My Own Ice Cream Cone: Slope Activities 1
Introductory lesson to using data to create a linear growth graph and model by building "fake" ice cream cones. Templates are included for the cones and scoops. Instructions for the teacher are also included. Contact me at hrudolph@orangecsd.org for details or clarification. Students will be introduced to appropriate vocabulary such as initial amount, slope, intercept, growth, increasing, model, trend, linear function or linear equation. Lamination is helpful for re-using the materials! A

Take a Bite Out of Algebra- Slope Activities 2
Students will literally take a bite out of a pretzel (or Twizzler) and predict the pattern if they would continue to eat it. A decreasing slope is discovered, and a model can be written to portray the situation. Students can predict how many bites it will take for the pretzel (or their fingers!) to be gone. Appropriate vocabulary should be introduced, including slope, intercept, trend, decreasing, and linear.

Bell Work - Equations
This is 5 day's worth of bell work to use as a review for standardized testing. Day 1-4 includes 3-5 multiple choice questions on equations and day 5 is a quiz with the same or similar questions with no multiple choice answers. I let the students use their notes on the quiz which holds them accountable for listening and writing down the correct answers when we go over the previous day's bell work.

Free Fall Lab
In this lab, students first use the free fall equation to calculate the theoretical time for a ball to fall from four different heights. Second, they do an experiment and record the actual time to fall. Third, they calculate the percent error between the two times. It is designed as an introduction to the free fall equation and provides a common experience for the teacher to expand upon. It also serves as a method for calculating percent error. Materials needed: 2 metersticks 1 ball 1 stopwatch

Equations of Lines of Best Fit: Liquid Battery Lab
In this lab, students will create a battery that can power an LED light using electrolyte liquids such as lemon juice, vinegar, or gatorade. Students will: make the battery, take data on how much voltage is created as they increase the amount of liquid used, determine the dependent and independent variables in this experiment, plot their data points on a graph, create a line of best fit, determine the equation of the line of best fit, and conclude what the slope of that line means conceptually.

Zip Lining Slope Between to Points Lab Activity
Goal: understand slope conceptually and calculate slope through any two points.
How do you plan to make the ratio of rise to run hands on and visual for students? How about by asking them to create zip lines? In this activity students will work in teams to create fast and slow zip lines using fishing line, paper clips, and any toy you can hang from the clip. Students will experiment with the ratio of rise to run as they must use the entire piece of wire for every zip line run meaning the onl

Scatterplots: Linear Regression Line of Best Fit:Forearms and Height (Editable)
After teaching my students about scatterplots, correlation, and the line of best fit, I take a day for them to do a hands-on lab, in which they measure their height (in inches) and their forearm length (from the tip of their elbow, to the bony point on their wrist), and we plot the class data, write the equation of the line of best fit, and then use the equation generated both forwards and backwards. They will need 45 minutes to an hour to do this in class.

Math Lab:Exponential Functions and Seed Overproduction vs Time/DISTANCE LEARNING
My students totally enjoy doing the following math lab! They invariably find it to be both fun to do as well as informative. They readily relate to discussions within.
* Students work with a partner
* Students begin by a brief discussion about seed overproduction
* Students are provided with assumptions used to complete the lab
* Students work collaboratively to determine the number of seeds in a bell pepper
* Students find the average number of seeds in a bell pepper using the totals
