1. The educator will engage the students in a discussion of the 3 states of matter.
2. The educator will use student knowledge and props to discuss molecule activity in each state.
3. Next, the educator will discuss the difference between a physical and chemical change.
4. The students will be led through an experiment to see a chemical change happen.
5. If selected, the students will then experiment with a physical change.
6. If time allows, we will take questions.
The student will be able to:
- identify if a substance is a solid, a liquid or a gas
- be able to identify the difference between a physical and chemical reaction
- understand that in order for an experiment to be successful, exact measurement is important

NGSS Learning Standards
P-PS1-1 Ask questions and use observations to test the claim that different kinds of matter exist as either solid or liquid.
K-PS1-1 Plan and conduct an investigation to test the claim that different kinds of matter exist as either solid or liquid, depending on temperature.
2-PS1-1 Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
2-PS1-4 Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot.
5-PS1-1 Develop a model to describe that matter is made of particles too small to be seen.
5-PS1-3 Make observations and measurements to identify materials based on their properties.
5-PS1-4 Conduct an investigation to determine whether the mixing of two or more substances results in new substances.
MS-PS1-1 Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2 Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-4 Develop a model that predicts and describes changes in particle motion, temperature, and phase (state) of a substance when thermal energy is added or removed.
MS-PS1-6 Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy during a chemical and/or physical process.
MS-PS1-8 Plan and conduct an investigation to demonstrate that mixtures are combinations of substances.
