This set of lessons is just the resource you need when you want your students to work as teams of scientists as they learn about a physical property of liquids. The activities are great for an open house, a science night, older students working with younger students, or activities to send home for families to share.

Here's what's included:

   ♥ A lesson overview video gets you started with a preview of the activities, materials, and resources. It's like I'm sitting next to you explaining your options;

   ♥ Seven activity videos can save set up and clean up time or be shown to a student absent from science class;

   ♥ A PowerPoint™ presentation contains a variety of images and can be used to spark a conversation before, during, or after the lessons. All the images are licensed under Creative Commons so you can use them in different contexts during your science class;

   ♥ A web site link provides more background information and additional suggestions for activities about the properties of liquids and evaporation;

   ♥ A student text with two different reading levels is included with color or blackline images, English text or Spanish text;

   ♥ The texts are recorded for students who benefit from hearing the information;

   ♥ A variety of assessments with suggested answers or a rubric gives you choices when assessing your students.

♥  ♥  You have several options for presenting this fun activity to your students ♥  ♥  

The activities use materials* that you can locate. Contact us if you need help with materials.

I modified the activities and added more resources to create and easy and fun way to share science through distance learning or as an independent activity, including: Distance Learning: Cohesion String, Distance Learning: Cohesion Coins, and Distance Learning: Cohesion Pepper!

This unit is part of a series about chemistry including: particles, solids, liquids, this product, physical change, and chemical change.

to see state-specific standards (only available in the US).
Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties. Observations could include color, texture, hardness, and flexibility. Patterns could include the similar properties that different materials share.
Make observations and measurements to identify materials based on their properties. Examples of materials to be identified could include baking soda and other powders, metals, minerals, and liquids. Examples of properties could include color, hardness, reflectivity, electrical conductivity, thermal conductivity, response to magnetic forces, and solubility; density is not intended as an identifiable property. Assessment does not include density or distinguishing mass and weight.
