Title: Lights, Camera, Action: Creating Videos to Investigate Changes When Mixing Two or More Substances
Description:

Students will collect data on an investigation where two or more substances are mixed together. Students will analyze the investigation to decide the type of change, chemical or physical, that occurred during the investigation. Students will use their observations from the investigation to create a short movie where they will describe the data they used to determine the type of change that occurred during their investigation. This lesson will work best for classrooms equipped with classroom tablets or schools that allow students to bring their own device.

This lesson results from a collaboration between the Alabama State Department of Education and ASTA.

Title: Substances and Chemical Reactions
URL: https://aptv.pbslearningmedia.org/resource/phy03.sci.phys.descwrld.lp_chemical/substances-and-chemical-reactions/
Description:

In this lesson, students observe chemical reactions that produce obvious effects (as opposed to reactions in which the substances appear not to change at all). They begin by exploring a different substance every day for one week. They compare the substances and learn that substances can be solids, liquids, or gases. Next, through teacher demonstration (or direct, supervised student involvement), students watch what happens when sand and water are mixed together (no chemical reaction), and when several pairs of acids and bases are mixed together (a chemical reaction occurs). Students then get to build their own "film canister rockets," using baking soda and vinegar as rocket fuel. This lesson concludes with open-ended thinking when students are asked to determine where rust comes from.

4 ) Provide evidence that some changes in matter caused by heating or cooling can be reversed (e.g., heating or freezing of water) and some changes are irreversible (e.g., baking a cake, boiling an egg).

3 ) Examine matter through observations and measurements to identify materials (e.g., powders, metals, minerals, liquids) based on their properties (e.g., color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, solubility, density).

Title: Acids and Bases StudyJam
URL: https://studyjams.scholastic.com/studyjams/jams/science/matter/acids-and-bases.htm
Description:

An object’s pH level can be tested using indicators. Objects with a low pH are acids, and those with a high pH are bases. Acids and bases react together to form water and salt.

The classroom resource provides a video that will introduce students to pH levels, acids, bases, and their possible reactions. This resource can provide background information for students before they conduct their own investigations. There is also a short test that can be used to assess students' understanding.

Title: Ooh, Oobleck!

Description:

Jump in with both feet as you watch oobleck (cornstarch and water mixture) videos and learn about three states of matter: solids, liquids, and gases. Learn to use captions and charts to make reading comprehension less messy and loads of fun.

7 ) Design, construct, and test a device (e.g., glow stick, hand warmer, hot or cold pack, thermal wrap) that either releases or absorbs thermal energy by chemical reactions (e.g., dissolving ammonium chloride or calcium chloride in water) and modify the device as needed based on criteria (e.g., amount/concentration, time, temperature).*

Title: The Transfer of Energy 1: Thermochemistry
URL: http://sciencenetlinks.com/lessons/the-transfer-of-energy-1/
Description:

This lesson is the first of a three-part series on energy transformation. All three lessons have the general purpose of increasing students' understanding of energy transfer, its role in chemical change, and the factors that can influence this change. This lesson is intended to increase students' understanding of heat and chemical reactions. Students will perform an experiment in which you will determine how the temperature of water changes when it is mixed with either calcium chloride or ammonium nitrate.
