Students will describe the motion of particles in solids, liquids, gases and plasma. Students will connect the transfer of heat to change in temperature and states of matter. Students will gain deeper understanding of the concept of temperature as it relates to phase changes in matter. Students will apply concepts to a variety of real life situations.

Goal

Students will describe the motion of particles in solids, liquids, gases and plasma. Students will connect the transfer of heat to change in temperature and states of matter. Students will gain deeper understanding of the concept of temperature as it relates to phase changes in matter. Students will apply concepts to a variety of real life situations. 

 

What will be done with my students

Students will investigate properties of matter, specifically temperature and how it affects phase changes. Students will conduct experiments with regular ice as well as dry ice. Then, students will participate in a "how low can you go?" temperature challenge while making ice cream in a baggie. Students will use Vermier Temperature Probes and laptops to conduct experiments. Students will observe a teacher demonstration using liquid nitrogen and observe its effect on various objects such as pennies, flowers, and marshmallows. Students will write about phase changes in a creative writing assignment. Students will take a pre and posttest to assess learning gains on Study Island, a computer software program. 

 

Benefits to my students

By completing hands-on activities, students will make real world connections to the abstract concept of molecular activity. Students typically struggle with concepts that involve very tiny objects (atoms) or very large objects (stars.) It's one thing to read about molecular activity, it's quite another to observe changes on a real-time graph of an experiment, which is what they will do in the ice cream lab! Students generally report that they remember all the science lessons that involved food, especially ice cream! 

 

Describe the Students

My students come from a variety of backgrounds. About 58% of the students are on free/reduced lunch. Some of the students struggle with reading comprehension and need extra reading classes to help them. Also, some of the students struggle with test anxiety, so they need multiple encounters with the science content. This builds confidence on standardized tests that are given by the district or the state on a regular basis (every nine weeks.) 

 

Budget Narrative

The Liquid Nitrogen Dewar is a special container used to transport Liquid Nitrogen. This will be purchased from Amazon.com and the liquid nitrogen is available from AirGas Supply. Dry Ice is available at the Bardmoor Publix. The Study Island program price was given as a quote this summer and the subscription lasts for the school year. The science supplies are for the ice cream in a baggie lab and other labs with temperature changes.
