Grade 8College. For a class of 30 students. Why just tell students about genetics when they can learn the basic principles of Mendelian genetics and the concepts of inheritance by observing real plants? This kit was previously titled 3, 2, 1Countdown to Genetics because students examine 3-day-old plants to study 2 phenotypes, allowing you to do 1 assessment of their understanding. All kit activities can be completed in just 3 class periodsand everything is included except a light source.
Product Details
Students germinate Wisconsin Fast Plants® seeds to study the inheritance of two phenotypes: stem color and seedling height. These phenotypes can be scored in the seedling stage. The P1 , F1, and F2 seeds are provided in the kit so students do not have to make the crosses themselves. They germinate the seeds, make predictions, and modify their predictions on the basis of data that they collect.
Time Requirement
One class period for teacher prep and pre-lab. Four class periods for investigations.
Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.
