SC.5.P.8.2

This lesson introduces how heat transfers to different substances using an electrical device. The electrical device used create thermal energy changes a substance’s state of matter. This lesson contains a lab experiment that tests the timing at which butter changes to its melting point while using a lamp. This lab questions whether using a different electric device will conclude the same results. 

This is lesson 3 in the Detecting Electrical and Thermal Energy Unit.

Type: Lesson Plan

In this lesson, 5th grade students will build an engineering device to separate oil from water in a simulated oil spill. Students will have an opportunity to learn about the impact that humans can have on the environment, both positively and negatively.

This is an Engineering Design Challenge that is best used after a unit or lesson that is aligned to science standards on solving problems or materials which dissolve in water. This challenge provides students a means to use their knowledge of the way materials will or will not dissolve in water to create and design an oil spill removal tool while learning the Engineering Design Process and being exposed to the field of engineering. This lesson is not intended as an initial introduction to the standard and would be best utilized as a culmination lesson.

This lesson gives students hands-on experience with sorting mixtures based on their properties. The students will relate these science standards to a real-world problem of eliminating trash in land fills. They will have to purchase the tools they use to create their assembly line to sort the garbage within the budget provided.

In this Model-Eliciting Activity (MEA), students will work in groups to develop a procedure to rank which self-made, children's drink would be best to add to a current coffee shop menu. Students will consider factors such as flavor appeal, temperature of drink , costs, time required to mix drink, special equipment needed and nutritional value. Students will apply knowledge of how temperature and stirring can affect dissolving time.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought processes. MEAs follow a problem-based, student-centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator. To learn more about MEAs visit: https://www.cpalms.org/cpalms/mea.aspx

This lesson uses the 5E model as students explore how various substances will dissolve. This is the first in a two part lesson. In the second lesson, students will compare how a substance will dissolve in varying temperatures. Students will learn about dissolving, mixtures, solutions and solubility.

Type: Lesson Plan

In this lesson, students will be experimenting with what independent variable will affect dissolving rates; students will compare results of peers to also determine materials that dissolve and do not dissolve from 5 given materials. Students will identify and learn what controls in an experiment are and their importance. This is a multi-part lesson that can be broken down by day or presented in one block. Complete all the Part A’s in each phase (Teaching/I Do/Know, Guided/We Do/Understand, Independent/You Do/Do) before Part B’s.

Type: Lesson Plan

This is part 2 of a lesson addressing solubility. Part 1 addresses how varying substances will dissolve in water. Part 2 addresses how temperature will effect solubility and the 5E lesson plan model will include a lab.

In this series of six investigations, students will participate in activities that help them better understand the different factors that affect the solubility of solids, liquids, and gases. First, students will add sugar and food coloring to different liquids to discover that substances don't necessarily dissolve in all liquids. Students will then add cocoa mix to hot and cold water, and see that this solute dissolves better in hot water. However, the following teacher demonstration shows that increasing the temperature of water has very little effect on the solubility of salt. Students also experiment with the effect of temperature on carbon dioxide gas dissolved in water. Students should conclude that temperature affects the solubility of substances in different ways. As a culminating challenge, students use their knowledge of dissolving solids, liquids, and gases in water to create a fizzy lemon soda.

Type: Unit/Lesson Sequence

In this unit, students will investigate M&Ms in water by posing questions, designing and conducting experiments to answer these questions, and developing explanations based on their observations. Students will investigate the effects of variables, such as temperature, on the rate at which the colored coating of M&Ms dissolves.
