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.…

Feedback Loops: Insulin and Glucagon
The Next Generation Science Standards includes feedback loops and homeostasis as a standard for life science. While homeostasis is a theme for many units in biology, feedback mechanisms are fairly specific. In fact, this is probably the most oddly specific topic found in NGSS. If you are trying to include it, most younger students…

Article: The Body Farm
This article has been adapted to model standardized test questions students, where the article is divided into columns and each paragraph is labeled with a number. Students are required to find information in the text and analyze text structures. Readers are asked to used context clues to understand difficult vocabulary. Students must also make…

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.…

Investigation: Why Are Cells So Small?
This activity requires students to practice math skills by measuring the surface area and the volume of boxes. Collect boxes for students to use, these can be any type of box, such as tissue boxes, food boxes, or shoe boxes. Ideally, you want a range of sizes, with at least one box being overly…

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…
