Human Population Growth
This activity was designed for home school during the Covid-19 pandemic. Students were completing a unit on ecology and had already done activities on trophic cascades. In this activity, students explore an interactive map and timeline that showcases major events in human history that impacted human populations, events like plagues or the development of new…

Saving a Fussy Predator, the Lynx
Read an article about the reintroduction of the lynx in Europe. A lynx is a type of feline. They are specialists, meaning that is has a very specific diet, the rabbit. Introducing the lynx poses challenges, but many people welcome its return. They are large cats, and can also pose a danger to livestock and…

Predator Prey Simulation
Interactive program allows students to manipulate the type of organisms within a system and what they eat.

Evolution of Caffeine
In this activity, students access a database called UniProt that provides information about protein sequences derived from genome sequencing. Students search for the protein sequences of three plants that produce caffeine, Camellia sinensis, Coffea arabica, and Theobroma cacao (tea, coffee, and cocoa). They compare the protein sequences to determine if the gene to create caffeine arose independently…

Biological Magnification
This article discusses how toxic substances accumulate in top predators in an ecosystem, a phenomenon called biological magnification. This accumulation can have dire effects on those populations and can threaten the entire species with extinction. Students read background information on mercury and DDT and how those toxins are measured in PPM (parts per million). A…

Genetics – Lop Ears
This worksheet allows students to practice doing genetic crosses that involve two traits. The first problem has the 4×4 Punnet square already set up. Once they fill out the square, they determine how many of the bunnies have floppy or long ears, and how many have black or pink noses. Note, these genetic traits are…

The Calvin Cycle
TED-ED video on the Calvin Cycle explains how the cycle works to create glucose. Students complete questions and label a diagram of the Calvin Cycle.

Frog Anatomy Label
This worksheet is a supplement to the frog dissection activity where students examine a preserved specimen. The main structures of the abdominal cavity are shown on this image and students practice identifying them using the included word bank. ( The worksheet could be modified to not include it should students need a greater challenge. )…

Horse Genetics
Practice genetic crosses with horse traits. The gait-keeper gene controls whether a horse will trot or pace and the flaxen gene determines mane color.

Practice with Taxonomy
Though Next Generation Science Standards does not emphasize the memorizing of major groups anymore, students can benefit from learning the basics of how animals are classified. Taxonomy is often introduced with evolution, where students learn how to analyze phylogenetic trees and create cladograms. This worksheet is a simple reinforcement exercise that covers the six kingdoms…

Genetic Crosses – 2 Traits
This worksheet was designed for freshman learning dihybrid crosses. Students struggle with setting up Punnet squares, so the squares are set up for them at first. Students only need to fill in the letters of the genotype can determine the phenotype proportions. A final task requires students to set up their own 4×4 square when…

Label Steps of DNA Replication
For freshman, DNA replication is only covered in basic terms, where students are told that the process is semi-conservative and leads to the production of two new identical strands. AP Biology students are required to learn te steps of DNA replication and the roles that enzymes like DNA polymerase, helicase, and ligase, play in the…

Human Population Growth
Students graph population estimates for years ranging from 1650 to 2012. The graph will show an exponential growth curve which students analyze to determine how frequently the population doubles. Students also explore the concepts of carrying capacity and growth rates. Questions ask students to discuss what happens when the earth exceeds its carrying capacity and…

Cell Cycle Label
This worksheet was created for freshman level biology and is a simpler version of a worksheet I use in the advanced classes showing the cell cycle. The image shows a cell in interphase, prophase, metaphase, anaphase, and telophase. Students label each phase and then identify structures within the cell that are important for cell division,…

Modeling Osmosis
This basic lab uses Deco-cubes to show how they change in size when soaked in salt water, distilled water, and tap water.
