Focus Questions

How can a mixture be separated? Where does the solid material go when a solution is made? How can you engineer or design a process to separate a mixture of dry materials?

How can a mixture be separated?

A mixture can be separated using a screen or a filter.

Where do the solids go in a solution?

When a solution is made, the solids dissolve and become transparent. A solution can be separated by evaporation.

How can you separate dry materials?

You can separate dry materials by observing the physical properties, such a particle size and shape, density or magnetism to determine what methods would work best.

Mixture or solution?

Check out the Crash Course Kids video below to explore more about mixtures and
solutions and some great real life examples! On Google Classroom you will find a fill in the blank worksheet to complete as well, outline key ideas about matter and mixtures and solutions.

Done with your work early? Check out the video below talking all about Mixtures vs Solutions! Hope you enjoy. When you are done you can write down what you learned in your science notebook.

What do I need to complete?

Google Classroom

Investigation 1 is now complete, including 1.1, 1.2 and 1.3. Check out the work below to see what you need to complete. Most science work is paper and pencil and in your science journal in school, but a digital checklist and grades will be posted on Google Classroom. Be sure to check out google classroom to see what is missing. Click below to find your google classroom.

Science Journal work for Investigation 1

Below you will find descriptions of the work from Investigation 1. All materials are in your science journal in school. Any work that is incomplete can be taken home to complete. Please be sure to return the science journal as soon as you are done, as we use it everyday in school. You can use the slideshows linked below for help completing any of the science work. If you missed an experiment, you can check the slideshows for descriptions of what took place or check with a classmate as well. On google classroom you will see a checklist of all work assigned and grades.

Investigation 1.1

During the science experiment, we observed the mixtures. Please write down observations for each of the three materials on color, texture, shape and size. Then, answer the question at the bottom, what happens when you add water?

Investigation 1.1

During the science experiment, we tried to separate the mixtures of water and gravel, powder and salt with screens and filter paper. Write down if the separation method worked. Then, answer the bottom question, writing down your observations of the experiment.

Investigation 1.2

During the science experiment, we used a balance to weigh water and a salt solution. Record your measurements in the top. Then write your observations of what we learned from the experiment at the bottom.

Investigation 1.2

During the science experiment, we used evaporation dishes to separate the salt solution. Draw a picture of the salt crystals in the evaporation dish. Write down your observations, being sure to use scientific words.

Investigation 1.2

During the textbook investigation, we read pages 5-9 about mixtures and states of matter. Please answer the four questions provided. Be sure to check the textbook for the answers to the questions.

Investigation 1.3

During the science experiment, students were given the opportunity to design their own experiment to separate dry materials. Write down your ideas on how to filter the mixture. After you conduct the experiment, be sure to write down the steps you completed to separate all the materials.

Investigation 1.3

During the textbook investigation, we read pages 10-14 about taking mixtures apart based on physical properties. We also discussed conservation of matter. Be sure to check the textbook for the answers to the questions.
