Data Analysis and Interpreting Graphs
Students practice analyzing pie charts, scatter plots, and bar graphs in the basic worksheet that is designed to pair with lessons on the scientific method. Most beginning biology students (in high school) are fairly adept at interpreting basic information from graphs, though scatter plots are sometimes challenging for them. I usually do this type…

Color the Parts of a Microscope
Students read text that describe the parts and functions of the microscope and ask them to color the parts as they read.
-
Microscope Labeling
This simple worksheet pairs with a lesson on the light microscope, where beginning biology students learn the parts of the light microscope and the steps needed to focus a slide under high power.

Investigation: Properties of Water (with Stats)
This investigation asks students to review the properties of water as they relate to life, usually a topic covered in the first or second chapter of most biology textbooks. Students then perform an experiment where they test the number of drops that can be placed on penny and compare that test to drops that…

Investigation: Tools and Measurements
I designed this activity to help students become familiar with basic equipment found in the lab. Students take volume measurements using a graduated cylinder, beaker, and a 3ml pipette. Ultimately, they must determine how many single drops of water are in 1 milliliter by designing a way to test this given the tools provided.…

Investigation: Processes of Science
Students must develop their own causal question about what biological factors affect a person’s lung capacity, Then test their hypothesis using a respirometer.

Lab Report Guidelines and Template
Help students organize a lab report for any experiment, includes basic layout: title, introduction, hypothesis, materials and methods, data, and conclusions.

Demo: BTB and Carbon Dioxide
I have used this demonstration every year to introduce the scientific method. The worksheet below is optional and includes instructions for writing a lab report and doing a more involved investigation, but for the beginning of the year, I prefer to just have students observe and give their suggestions for how to test various hypotheses.…

Video Lessons and Taking Notes
Many teachers have adopted a “flipped” model of instruction, where students view lectures from home and then use class time for discussions, experiments, and problem-solving. I have not fully gone to this model because many of my lectures have been redesigned as cases and include information with a discussion and a problem to solve.…

Investigation: What Factors Affect Seed Germination?
This activity can be used as part of a unit on plants or as an activity to illustrate the scientific method. The materials are cheap and can be obtained from the grocery store. Students design an experiment to determine what factors affect seed germination. They are given a list of variables that are appropriate…

Investigation: Stride Length and Bone Lengths
This activity is intended to introduce students to spreadsheets while also reinforcing concepts learned in the unit on the skeletal system. While graphs may be easier to create using google sheets, student can still create graphs by hand using graph paper. Your class will need a set of meter sticks or rules to…

Investigation: What Factors Affect Cricket Chirps?
One of my favorite scientific method activities was a project that used a flash simulation to investigate cricket chirps and how the frequency is affected by temperature, humidity and wind speed. Unfortunately, flash is no longer supported by modern browsers. This alternative assignment asks students to listen (and count) cricket chirps, create a data…

How to Use a Spreadsheet to Create a Graph
High school teachers often assume that their students know how to use basic word processing programs, internet browsers, and spreadsheets. My students come to me with very little knowledge in how to do advanced tasks in those platforms, like inserting a graph or image. I created this assignment to give students an introduction into…

What Are Logical Fallacies?
This activity can be a good introduction to logic and how fallacies can undermine claims in an argument. This can be included in introductory lessons on the scientific method and instruction on how to formulate and support conclusions with data. I’ve also found this to be useful before lessons on evolution where we discuss myths…

Scientific Method in Action
This simple worksheet has two reading passages, similar to what students may see on state standardized science tests. Students read a short description of a science experiment and must answer questions related to science methodology, such as identifying controls and variables and summarizing conclusions that can be drawn from the text. The two stories are…
