Middle School Curriculum

Back in 1963 when LAB-AIDS® shipped its first kit, we had a vision, to revolutionize the middle school classroom with one of the first inquiry-based approaches to learning science through hands-on activity. More Info

What are the ethical issues involved in using genetic information?
Students explore how organisms get their traits and what causes variation from one organism to another. They also analyze and interpret evidence for how certain traits affect reproduction. Students learn how both genes and the environment can influence traits and apply what is learned to a human genetic condition.
PE Assessment Example:Think back to what you know about Marfan syndrome and fibrillin. Draw a labeled diagram that models the cause-and-effect relationship between the fibrillin gene, fibrillin protein, and traits/ symptoms for a. a person without Marfan syndrome, b. a person with Marfan syndrome.

Reproduction is part of Issues and Science three year middle school program, designed by SEPUP at the Lawrence Hall of Science. This three to four week unit anchors the lessons around the the socio-science issue: What are the ethical issues involved in using genetic information? Investigative phenomena within the 14 activities connect back to the issue and storyline. This unit builds towards and assesses PEs LS1-4, LS1-5, LS3-1, LS3-2.


Content in Reproduction | NGSS is organized into 14 activities, as follows:

Activity Title Activity Type Activity Overview
1. Joe's Situation View and Reflect Students are introduced to a scenario of a student who has just learned he may have inherited a genetic condition (Marfan syndrome).
2. Creature Features Modeling Students develop models to investigate the inheritance of a trait in imaginary creatures.
3. Reproduction Reading Students read about the differences between sexual and asexual reproduction at the cellular level.
4. Gene Combo Investigation Students model the inheritance of single-gene traits by collecting and analyzing data from coin tosses.
5. Gene Squares Problem Solving Students use Punnett squares to model sexual reproduction and predict the approximate frequencies of traits among offspring.
6. Mendel, First Geneticist Reading Students read about Gregor Mendel’s experiments with pea plants.
7. Do Genes Determine Everything? Laboratory Students design an experiment to investigate the effect of the environment on such plant traits as seedling color.
8. Show Me the Genes! Reading Students read about the behavior of chromosomes and the function of DNA during sexual reproduction.
9. Breeding Critters-More Traits Investigation Students create imaginary critter offspring to model patterns of inheritance and develop explanations of what happens in terms of genes, chromosomes, and environmental effects.
10. Animal Behavior Investigation Students read one of four real case studies on a behavioral or physical trait in an animal. They examine and interpret graphs to argue for how those traits increase the animal’s reproductive success.
11. Plant-Animal Interactions Investigation Students read about four different flowers and four different pollinators. They construct an argument for how the structure of the plant increases its reproductive success by attracting a specific type of pollinator.
12. How Do Genes Produce Traits? Modeling Students use a simplified codon table to determine part of the fibrillin protein sequence from a given DNA sequence and explore the protein’s three-dimensional structure.
13. Fault in the Genes Modeling Students model mutations and their effects on protein sequence and structure.
14. Advising Joe Talking It Over Students revisit the Marfan scenario and use a model to construct an explanation of what is going on and an argument about what Joe should do.

Lab-Aids® provides several useful tools to guide you and your students through the Reproduction unit:

Reproduction | NGSS

Student Book

The Student Book guides students in exploring a socio-science issue and connected phemonena through a series of varied activity types. Activity types use one of twelve different instructional strategies to apply Science and Engineering Practices to specific Disciplinary Core Ideas and Cross Cutting Concepts.

SEPUP's integrated literacy strategies help students process new science content, develop their analytical skills, make connections between related concepts, and express their knowledge orally and in writing. The built-in assessment system helps teachers identify students' strengths and weaknesses from the beginning of the unit. This allows them to adjust activities when needed so that all students get the best chance to build their knowledge and appreciation of science. At the back of the Student Book there is an Appendix containing additional resources for students, such as science skills, literacy strategies, and media literacy among others.

Lab-Aids® Science Lab Notebook

A science notebook not only models the way scientists work, but it helps to develop and reinforce students’ science learning and literacy skills.

The Lab-Aids Science Lab Notebook is designed to support best practice note-booking strategies. It includes three-hole punched pages in a two-column design for Cornell-style notes. GraphAnywhere pages allow students to both write and easily create data-tables and graphs anywhere on the page. The unique “Lab-Log” column serves as a blank canvas for drawings, connections, and self-reflective notes. 160 pages total.

Teacher Edition and Resources

The SEPUP Teacher Edition (TE) guides you through each activity in the Student Book and helps you see the development of concepts within the big picture of the unit. It helps you set up the equipment from the kit, organize the classroom, conduct activities, and manage practical details, all of which enhance students’ learning environment.

The Teacher Edition text is broken down into several sections, such as Activity Overview, NGSS Connections and Correlations, Materials and Advanced Prep, Teaching Summary, and Background information to name a few. The Teacher Edition is packaged as a color-printed, loose-leaf binder which allows you to personalize it with highlighting, annotations, rearrangements, and insertions. It provides full support for teaching the program. Additional support resources can also found in the Teacher Resource book.

The Teacher Resource (TR) provides background and suggestions to increase the overall effectiveness of implementing the program across all levels of learners. Some sections include: SEPUP’s Approach to Teaching and Learning, Differentiation Strategies for Diverse Learners, Literacy Strategies for Supporting Reading Comprehension and for Enhancing Students’ Writing, and comprehensive instruction on the SEPUP Assessment System. There is also a section containing unit specific resources, such as overviews, unit storyline and phenomena table, NGSS correlations, assessment blueprints, and item banks."
