Week of 3/16 students will complete their final NYS required lab.
The New York State “All Mixed Up” Lab is a required middle school science investigation that focuses on how substances mix and separate. In this lab, students explore how different materials can be combined into mixtures and then separated using their physical properties.
During the investigation, students are given a mixture of several substances (often things like sand, salt, iron filings, or other materials) and must design and carry out a plan to separate the components. They test different separation methods such as magnetism, filtration, evaporation, and sieving.
The goal of the lab is for students to understand that mixtures can be separated because the substances in them keep their own physical properties. Students collect data, explain their reasoning, and justify why certain separation methods work based on the properties of the materials.

TEST NEXT WEDNESDAY 3/18/26 on Traits and Reproduction. Here are key concepts to review:
1. Traits and Variation
1. Traits and Variation
Traits are characteristics of organisms (ex: eye color, fur color, height).
Traits can be inherited from parents or influenced by the environment.
Individuals within a species show variation, meaning traits can differ among members of the same species.
2. Inheritance
2. Inheritance
Organisms inherit traits from their parents during reproduction.
Offspring receive genetic information from both parents, which leads to combinations of traits.
Patterns of inheritance explain why offspring resemble their parents but are not identical.
3. DNA as the Instruction Molecule
3. DNA as the Instruction Molecule
DNA contains the instructions for building and maintaining an organism.
DNA carries the information for traits.
DNA is located in cells and is passed from parents to offspring.
4. Genes and Proteins
4. Genes and Proteins
Genes are segments of DNA that contain instructions.
Genes provide instructions for making proteins.
Proteins help determine how traits appear (for example, proteins that produce pigments).
5. Protein Production
5. Protein Production
Cells use the instructions in DNA to build proteins.
The type and amount of protein produced influences the traits an organism displays.
6. Sexual Reproduction
6. Sexual Reproduction
In sexual reproduction, two parents contribute DNA.
Offspring receive half their DNA from each parent.\
This mixing of DNA leads to genetic variation among offspring.
7. Predicting Traits
7. Predicting Traits
Scientists can use models to predict how traits may be passed to offspring.
Some traits follow recognizable patterns of inheritance.
8. Environmental Influence on Traits
Not all traits are controlled only by genes.
Environmental factors (nutrition, sunlight, temperature, etc.) can influence how traits develop.
