This worksheet helps students to determine which candidate is the long lost son who should get the inheritance after a couple dies. Types of problems include: monohybrid crosses, co-dominant dihybrid (blood typing), incomplete dominance, and a
This labeling worksheet provides a review of the processes of Cellular Respiration and Photosynthesis (what moves into & out of each process). The 1st page is basic knowledge of the processes, focusing on where the cellular energy comes from
In this lab, students investigate how a combination of genes work together to create an organism. This activity helps to reinforce basic patterns of inheritance: dominant/recessive, incomplete dominance, codominance, and sex-linked traits.
This activity is an example of a population of bears changing over time once a predator is introduced. It compares 2 arm variations: hands up or hands down.
Prep for this lab includes copying & laminating sets of bear cards (3 pages per
This activity helps to reinforce metric measurement by having students measure each other and convert to mm, cm, & m. They also create a bar graph of the information. I use this at the beginning of the year to practice metrics – something the
In this lab, students experiment with genes and environment for a population of toothpick “fish”.
They should have an understanding of basic genetics (genotype & phenotype) before this activity. Concepts covered include: genetics review,
This worksheet walks students through the idea of evolutionary fitness, using 4 lions as examples. They begin by using current knowledge & ideas about fitness to make a claim about the lions. Next, they discuss each lion (ideally with a
Using what students currently know about their body, they decide who would “win” in a battle to find out which body system is “most important”. Complete each battle by justifying the answer using as much scientific evidence as you can to defend
This activity helps to reinforce the genetics of sex-linked traits. There are three scenarios with different sets of parental genes which students use to model the transmission of X & Y chromosomes.
Supplies needed: *some minimal set up is
This is the format I use for all of my student's lab reports. Each student has a lab notebook (composition style) that they use throughout the year to document their learning. They are always amazed when they look back at the end of the year and
My students always "get" 1 trait Punnett squares right away, but need a lot more help with 2 traits. I came up with this guide to show them 2 ways of completing the task, both will get you the correct answer. I like to ask them: "Do you like big
In this activity, students will make a small terrarium that will allow them to observe and measure the water given off through transpiration. The investigation takes a few days, to give the plants time to transpire. Students then graph the class
