Color the North American Biomes
This coloring activity is suitable for beginning biology students who are learning about the plants and animals found in each major biome. The worksheet does require a basic geography knowledge, which I found somewhat lacking in my freshman students. I usually place a large map of North America on the overhead projector for students…

Color the Neuron and Neuroglia
Students can practice what they have learned about neurons with this simple coloring activity. The page shows features of the neuron, such as the axons and dendrites. They will also color the supporting cells of the matrix. There are no instructions, students must identify each of the types of glial cells: oligodendrocytes, astrocytes, microglial cells, ,…

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: Estimating Population Size
In this investigation, students simulate how mark and recapture techniques are used to estimate population size. Prepare populations in advance by gathering 60-150 small objects, like toy spiders, beans, or beads. Toy animals seem to be more exciting for students, and you can sometimes find them at dollar stores. In my class, I…

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…

Manipulate DNA in a Simulation to Explore Mutations
This activity uses a simulation from the Concord Consortium. It shows how DNA is transcribed to RNA and then turned into a protein. It’s a very clear animation and can be used on its own as part of a lecture on protein synthesis. I have even used this as a demonstration to show protein folding…

Color the Cellular Structures of the Ameba
This worksheet describes the structures of the unicellular protist known as the ameba. Though NGSS standards do not require units on protozoans, this can still be a useful exercise for examining how structure relates to function and how single-celled organisms move, consume food, and reproduce. What is the amoeba? An amoeba is a type of…

Color a Typical Prokaryote Cell
This worksheet is similar to the animal cell coloring and the plant cell coloring, where the focus is on structures found in the cell and how those structures relate to the cell’s function. Students read a short passage about prokaryotes and the two kingdoms of bacteria: archaeabacteria and eubacteria. The passage includes information about…

Case Study: How Do Genes Determine Skin Color?
This case study focuses on a news story whose headline declares that a “mother is a the only black woman to give birth to two white babies.” Students look past the sensationalized headline to discover how skin color is controlled by multiple genes and make a final judgement about whether statements made in the…
