Lab report physical and chemical changes

Macroscopic patterns are related to the nature of microscopic and atomic-level structure. Introduction and Connection to the NGSS and Common Core In this lesson, students go through a series of 12 quick lab stations in order to practice identifying reactions as chemical or physical changes.

At each lab station, students not only identify the signs of a chemical change, but they also read reactant and product descriptions in order to identify changes in chemical and physical properties that occurred.

Each station is quick, fun, and very specific to to standard MS-PS! Science and Engineering Practices: When students look for patterns in data to identify the signs of a chemical change based on their qualitative observations, they do just that!

At each lab station, students use patterns in evidence to identify each reaction as chemical or physical. Students thus realize that patterns can be used to predict phenomena. Patterns Connecting to the Essential Question: What are you supposed to learn today? And, what evidence can show how the physical and chemical properties of the substances change?

Explain to students that we will again be working with Skill CH. Have students turn to their unit plans and silently read the skill. After reading the skill, students rank their current level of mastery on a scale of 1 to 4 4 being mastery.

Students in my room have already assessed themselves in the lesson prior to this; this would be an opportunity for the student to change their number if they felt their level of mastery had increased after the previous lesson.

In my classroom, students frequently self-assess their level of understanding on each skill in the unit as we go. As you can see from the image below, this student ranks has continually updated his level of mastery on each skill has his learning has developed.

Students in my class have already had an introduction to the differences between chemical and physical reactions. My students have already worked through the Skill CH. For a look at all the lessons that have led my students to this point and where we go from here check out the lessons in these units: Molecular Arrangement and Phase Changes: Focuses on Skills 1 - 4 of the Chemistry Unit Plan This unit is designed to answer the Essential Question, "How do particles combine into new substances?

What evidence can show how the physical and chemical properties of the substances change? It particularly focuses on types of matter, physical properties, phase changes, and factors that affect physical properties.

Stazi Belvin Chemical and Physical Lab Changes Lab Report 9/5/ I. Purpose- The overall purpose of the lab is to identify chemical and physical changes. II. II. Safety- To work with the chemicals used in the lab, it is required to wear safety goggles to protect your eyes from the fumes when working with the chemicals. Pearson Prentice Hall and our other respected imprints provide educational materials, technologies, assessments and related services across the secondary curriculum. Physical Changes vs Chemical Changes Lab • What was done? • What can you observe? • Is it a physical or chemical change and why? folds • Is it still paper? • Is this a physical or chemical change? #1) Crumpling Paper Crumpling paper does NOT change the nature of the paper. It puts creases and folds in the paper, but does not .

It stresses group discussion, discourse and utilizing text references when engaging in argument. Students utilize reading, writing, and speaking strategies in order to develop scientific literacy.

Chemical Properties and Reactions: Focuses on Skills 4 - 6 of the Chemistry Unit Plan. This unit is also designed to answer the Essential Question, "How do particles combine into new substances?

This unit focuses on chemical properties and chemical reactions. Students analyze evidence and property changes that allow them to distinguish between chemical and physical reactions.

In addition, students investigate the Law of Conservation of Mass as they look at how bonds are broken and formed in chemical reactions. This unit is full of hands on labs and station rotations that will engage any middle school student in chemistry!

Chemical reactions result in a change of properties! Let the students follow them. In the previous two lessons Chemical Reactions Un-Notes and Chemical Physical Group Challengestudents have been developing an understanding of the difference between a chemical and physical reaction.The Ellington lab is an idea factory, where your ideas are welcome.

What is Science?

Throughout its existence, the Ellington Lab has generated impactful new technologies and approaches. Flinn Scientific is the #1 source for science supplies and equipment both in and outside the classroom.

For more than 40 years, Flinn has been the “Safer Source for Science.”. Stockfeed and Petfood products which are excluded from registration. To be excluded from registration with the APVMA, an animal feed product must be one that is fed to, and voluntarily consumed by, an animal and meet specified requirements in relation to ingredients, manufacturing, labelling and claims.

Lab 4: Chemical and Physical Changes Humans having a desire to classify things so they are more understandable. The Periodic Table of the Elements grouped elements according to their increasing mass (a physical property) and by columns (similar chemical properties).

10/21/–Idaho State Police Forensic Services has recently received a number of important federal grants. These federal grants play a huge role in the laboratory system remaining one of the most efficient, productive, and progressive forensic laboratories in the country.
