States of Matter

A Museum of Science Traveling Program Description

States of Matter is a 60- minute presentation about the characteristics of solids, liquids, gases, and the temperature- dependent transitions between them. It is designed to build on NGSS-based curricula.

NGSS: Next Generation Science Standards Needs

We bring all materials and equipment, including a video projector and screen. Access to 110- volt electricity is required. Space Requirements The program can be presented in assembly- suitable spaces like gyms, multipurpose rooms, cafeterias, and auditoriums. Goals: Changing State

A major goal is to show that all substances will go through phase changes and that every substance has its own temperatures at which it changes state. Goals: Boiling

Liquid nitrogen boils when exposed to room temperature. When used with every day objects, it can lead to unexpected results! Goals: Condensing

Placing balloons in liquid nitrogen causes the gas inside to condense, shrinking the balloons before the eyes of the audience! Latex-free balloons are available for schools with allergic students. Goals: Freezing

Nitrogen can also be used to flash-freeze a variety of liquids. Students are encouraged to predict the results, and may end up surprised! Goals: Behavior Changes

When solids encounter liquid nitrogen, they can no longer change state, but their properties may have drastic—sometimes even shattering— changes. Finale

Likewise, the properties of gas can change at extreme temperatures. At the end of the program, a blast of steam is superheated… Finale

In addition to these core goals, other concepts are taught with a variety of additional demonstrations. Program Details

• Can only be booked for school groups during the school year. • Only available, in slightly different versions, for second- or fifth-grade students studying the program content. Program Details

• Capacity is up to eight classes (200 students) of a single grade per session. • Up to two consecutive sessions can be taught per day. NGSS Connections • 2-PS1-1. Describe and classify different kinds of materials by observable properties of color, flexibility, hardness, texture, and absorbency. • 2-PS1-4. Construct an argument with evidence that some changes to materials caused by heating or cooling can be reversed and some cannot. • 5-PS1-1. Use a particle model of matter to explain common phenomena involving gases, and phase changes between gas and liquid and between liquid and solid. • 5-PS1-3. Make observations and measurements of substances to describe characteristic properties of each, including color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility. NGSS Scientific and Engineering Practices

• Asking questions and defining problems. • Planning and carrying out investigations. • Developing and using models. • Constructing explanations and designing solutions. 2019 – 2020 Prices
