Students use a thermal process approach to design, build and test a small-scale desalination plant that is capable of significantly removing the salt content from a saltwater solution. Students use a saltwater circuit to test the efficiency of their model desalination plant and learn how the water cycle is the basis for the thermal processes that drive their desalination plant.
This engineering curriculum meets Next Generation Science Standards (NGSS).

Learning Objectives

After this activity, students should be able to:

Science & Engineering Practices

Disciplinary Core Ideas

Crosscutting Concepts

Develop a model to generate data to test ideas about designed systems, including those representing inputs and outputs.

Models of all kinds are important for testing solutions. The iterative process of testing the most promising solutions and modifying what is proposed on the basis of the test results leads to greater refinement and ultimately to an optimal solution.

Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success. (Grades 6 - 8 ) More Details

Science & Engineering Practices

Disciplinary Core Ideas

Crosscutting Concepts

Analyze and interpret data to determine similarities and differences in findings.

There are systematic processes for evaluating solutions with respect to how well they meet the criteria and constraints of a problem. Sometimes parts of different solutions can be combined to create a solution that is better than any of its predecessors. Although one design may not perform the best across all tests, identifying the characteristics of the design that performed the best in each test can provide useful information for the redesign process-that is, some of the characteristics may be incorporated into the new design.

Introduction/Motivation

How much of the water on our planet do you think is available for drinking? (Give students a few seconds to think about this.) Of the total water available on our planet, less than 1% is safe for drinking. In fact, the world's water consumption rate is doubling every 20 years, outpacing by two times the rate of population growth. It is projected that by the year 2025, water demand will exceed supply by 56%.

Luckily for us, the oceans are full of water - except that we just can't fill a glass with ocean water and drink it! Engineers have been working on technologies to transform ocean water into drinking water. One technology they have created is based on a thermal process that is a controlled approximation to the naturally-occurring water cycle. What is really cool about this technology is that the water cycle occurs by nature on our planet and engineers have thought of ways to mimic this process on a smaller scale.

During the next few days, you are going to design and build a model system that takes in saltwater and removes as much of the salt as possible. You will also test the efficiency of your system using a saltwater circuit. We are going to use the engineering design process to help us create our desalination plant. Has anyone ever heard of the engineering design process? Do you know what it is? (Take suggestions from students.) It is a series of steps that engineers follow, kind of like how scientists follow the scientific method, but these steps are used to solve solving engineering design problems.

Procedure

Background

The thermal desalination approach involves heating saltwater until it evaporates and then forcing the evaporated water to condense. The condensed water is clean water. This type of process is used to produce more than 85% of the desalinated water in the world. This approach mimics the water cycle; in fact, each step in a thermal process can be linked to a stage of the water cycle (see the attached Water Desalination Plant Presentation PowerPoint).

In this activity, students design a model seawater desalination plant using a hot plate as the heat source (see an example in Figure 1).Refer to additional background information for this activity in the associated lesson, Ocean Water Desalination, and associated activity, Saltwater Circuit.

An important aspect of this project is to give students opportunities to make mistakes. It is common for students to not consider in their initial designs all aspects of how the desalination plant will ultimately work. But through a few design iterations, they improve their designs, until their plants work. This process mirrors the real world in which the steps of the engineering design process are followed and repeated to correct design deficiencies.

The basic steps of the engineering design process (sometimes called the engineering design loop) include: identify and understand the need, brainstorm and develop possible solutions, select the most promising solution, make a design plan, construct a prototype/model, test and evaluate the prototype/model, and redesign and improve. A successful model or prototype serves as the mock-up for a full-scale product or system. Engineering teams often iterate a design many times before determining the final solution to a challenge. See more information on the engineering design process at https://www.teachengineering.org/engrdesignprocess.php.

Before the Activity

Gather materials.

Cut the aluminum foil into 12 x 12 in (30 x 30 cm) pieces, one per team. Cut a few extra sheets in case some teams are unable to build a working plant on their first try and need more than one piece.

Make copies of the Design Worksheet (one per team) and the Reflection Worksheet (one per person).

For Day 1, set up a projector to show the PPT presentation.

For Day 2 and Day 3, have a cooler full of ice.

Divide the class into groups of three or four students each.

With the Students-Day 1

1. Show students the attached Water Desalination Plant Presentation (PowerPoint).

2. Show students the materials available to build their model desalination plants. Have one or two sets available for them to examine. Hand out the Design Worksheets, one per team.

3. Review the steps of the engineering design process (write them on the board).

4. Give teams time to brainstorm ideas and come up with labeled diagrams and drawings of what they intend to create with the given materials. Encourage them to get several ideas down on scrap paper. Use the worksheet to document the final design.

5. Review and approve designs at the end of class. Acceptable designs are detailed, labeled diagrams that show what the model plant will be made of and look like.

With the Students-Day 2

1. Give teams time to construct their model desalination plants.

2. Once a team has completed their model, have the team begin testing. Give each team 20 to 35 grams of salt, 32 fl oz (946 ml) of water and 2-4 cups of ice. (Use about a 3:1 ratio of water to salt. During the testing phase, set hot plates to their highest setting.)

3. Once a team has its plant running, have team members take turns visiting other groups' stations to ask questions about their designs, and provide the comparative research information and ideas requested on page 3 of the Design Worksheet.

4. After the desalination plants have been running for 20 minutes or so, have the team check to see if they are collecting water. Answer the questions on the Design Worksheet.

5. If no water is collected, direct students to analyze their design and redesign with improvements.

6. Before the class period is up, have students make notes on their design worksheet on what worked and what didn't. Let them know that the next class period will be the final class period to get a working desalination plant.

7. For teams that successfully collect water, have them use their saltwater circuit to test the water for salt. If the light bulb turns on, then salt is present in the recovered water. If the light bulb does not turn on, then is no salt (or significantly reduced amount of salt) is present in the recovered water. Success!

8. While going from team to team, note the kinds of designs and their major features, so as to prepare for the next class period when you will begin with an overview of different designs.

With the Students-Day 3

1. To help students reach a working design, spend about 10 minutes at the beginning of the class drawing three different designs on the board and leading a class discussion about what would work and not work. You could use Figures 2 and 3 (one is workable, one is not); you could also incorporate student design examples observed from step 8 on Day 2.

2. Give teams about five minutes to revise and improve their designs.

3. Replenish any materials students may need and give students time to build and test their revised model desalination plants.

4. It is possible that not all teams will achieve a working design by the end of Day 3. This does not mean the team has failed. In engineering --- much is learned from failures. Ask each team to write a summary paragraph describing their model plant and its performance.

5. Conclude by having each student complete the Reflection Worksheet, as described in the Assessment section.

Figure 2. A failed design for a desalination plant, because the clean, condensed water falls back into the seawater.

The design drawn in Figure 2 does not have a chance to work; the water that is evaporated by the hot plate condenses on the bottom of the plastic bin and falls back into the original saltwater solution. The design team failed to consider how to collect the water that condenses at the bottom of the plastic bin.

The design shown in Figure 3 could work; the water evaporated by the hot plate condenses at the bottom of an angled plastic container that directs the clean water into a collector cup.

Figure 1: A working design for a saltwater desalination plant.

Vocabulary/Definitions

engineering design process: A series of steps that engineering teams use to guide them as they solve problems. Sometimes called the engineering design loop.

input: The object(s) going into a system.

iteration: Repeating a series of steps to get closer to a desired outcome (that is, re-design, re-test, re-build to get nearer to an optimal engineering solution to a specific problem). Also: A version of the final product or solution. For example: Our third iteration passed the saltwater circuit test.

Assessment

Pre-Activity Assessment

Class Discussion: After showing the Water Desalination Plant Presentation PowerPoint, lead a class discussion.

Activity Embedded Assessment

Design Worksheet: Teams use the worksheet to sketch their design schematics and details, collect comparative information on the designs of other teams, and answer questions about their testing results.

Post-Activity Assessment

Team Writing Assignment: Whether or not teams achieved a working design, ask them to conclude their work by composing a summary paragraph describing their model plant and its performance.

Reflection Worksheet: By answering the four questions on this worksheet, students individually describe what they learned in this activity and how it can be improved. Review worksheets to gauge students' mastery of the subject matter. Questions: Describe the thermal water desalination processes; With which part(s) of the design process did you help? What did you learn in this activity? How would you change this activity for future classes?

Safety Issues

Use eye protection during this activity.

Hot plates can get extremely hot. Watch that students do not touch or throw water on them.

Activity Scaling

For Lower grades, show a demonstration of the model desalination plant, test its water output with a saltwater circuit, and make comparisons to the natural water cycle.

For upper grades, allow teams to choose the saltwater concentration for their model plant.

Introduction: Hot Dog Cooker / Solar Oven

This Hot Dog Cooker / Solar Oven is simple and easy to make. We have had it reach temperatures over 170 degrees Fahrenheit on a cloudless 80 degree day. Today is a pretty cloudy low 80s day and the oven still was over 115 degrees.

Step 1: Materials

Materials

1. Pringles can or other cylindrical container.

2. Sharp knife, make sure you can handle a sharp object or ask for help. Kids - ask a responsible adult for help.

3. Straight edge, we used a cut piece of aluminum laying around but a ruler would be good.

4. Sharpie marker or other marking pen.

5. Skewer

6. Hot Glue

7. Drill / Drill Bit

Optional
Magnet, Plastic Wrap, Tape

Step 2: Procedure

Empty contents. Fat Cat had no problem eating the chips in our cans to "help" us out.

Using a straight edge draw a rectangle on the side of the can. We used this side because there were lines already.

Use your knife to cut the rectangle out. Save this piece for later.

Using your skewer, poke a hole through the plastic lid.

Take skewer out and put plastic lid on to bottom of can.

Mark can where hole should go on the bottom of the can.

Drill hole with drill in bottom of can.

Put skewer through the lid, the center of can, and the bottom hole.

Step 3: Stand

Use the rectangle piece we cut out to make a stand. This will help keep the oven from flipping over.

Take the scrap piece and run a bead of hot glue along the center of the piece. Do not put on the shiny side.

Place the scap piece to the can. Try to make sure that when the solar oven is set down that it will be angled at the sun and not straight up or straight forward. We eyeballed it.

If you want to be exact, use a protractor to determine angle. Different parts of the world get different angles of sunlight and an oven angled properly will get more direct sunlight into the oven causing higher temps.

The stand also allows for different angles. Just rotate the can on its side. Experiment with it and you will see.

Step 4: Extras

We like magnets. So we put a magnet on the bottom of this solar oven. It helps keep it in place and allows for many different angles. We had it hanging on the back of a metal chair out in the yard. Just seemed to be the thing to do lol.

We added plastic wrap to one to keep heat in. We need to experiment to see which oven cooks hotdogs better.

Step 5: Success?

Today was a very humid day and cloudy. When we brought the oven up from the basement, the thermometer read around 70 F after about 10 min it was up over 115 F. Outside temp was 82 F.

I don't know if that was much of a success but I know on a sunny day we had the thermometer reading over 170 F on an 80 F day.

Remember to keep adjusting / moving can as the sun moves.

Did you know that you can make your own barometer using items from around your home? I had no idea! My kids love science experiments, so I can't wait to try it! Today, Joanna from The Blue Barn here sharing her DIY barometer tips and tricks. Until I read her post, I had no idea I could make one at home so easily. Love it! Read on for full instructions!

I'm so excited to be writing today for the lovely Tammy of Housing a Forest. My name is Joanna I'm originally from Wales, U.K but now live on the East Coast of the United States with my hubby, four children and way too many animals to remain sane. I'm chief creator at Blue Barn Living and you can normally find me and all our messy fun projects over on Instagram @thebluebarn.

Here in Connecticut we are heading into Spring and despite a few late snow storms we are expecting milder rainy weather because everyone knows that 'April rain brings May flowers'. This makes it the perfect time of year to get the kids thinking a little about the weather and how we can predict some of these seasonal showers. Welcome the Barometer.

A Barometer as described by Google, ( noun) is an instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.

The first Barometer is credited to an Italian called Evangelista Torricelli who is said to have invented it in 1643. However, there were thought to be a number of Italian scientists and astrologers working in the area of vacuums and air pressure at this time in the 17th century.

A barometer measures air pressure: A "rising" barometer indicates increasing air pressure; a "falling" barometer indicates decreasing air pressure.

Many barometers use Mercury tubes to help measure the air pressure but today we are going to make one that will work using a few items you have around your house.
You will need Step 1
Take your balloon and cut the neck of the balloon off.
Step 2
Taking the bottom part of the balloon stretch it over the neck of the jar. A younger child might need help with this as you should pull it as tight as possible so the balloon fits flat with no dimple in the middle.

Secure the balloon in place with a thick elastic band. This now creates a sealed vacuum in the jar.
Step 3
Cut a straw at an angle to create a pointer.

Tape the straw to the center of the balloon. Make sure the end of the straw ends in the center.
Step 4
On a piece of card draw a sunshine towards the top and a rain cloud towards the bottom. Mark the paper in the middle where the straw currently rests.

Now the children can step back and observe the barometer over time. What do they observe? Does their Barometer change? Does it move a lot or a little? Could they tell when it was raining v sunny? Ask them why they think this is happening?

You can explain to them that air is made up of tiny particles called molecules. The air inside the jar has been trapped by the balloon so no molecules can escape but they press against the balloon and the sides of the jar.

There is also air outside the jar, this air also contains molecules that push against the balloon from the other side.

If the pressure inside the jar is greater it pushes the balloon to dome outwards. If the pressure inside the jar is less the outside air molecules push the balloon inwards. The balloon causes the straw to point up or down depending on which way the pressure is greatest.

The weather causes changes in air pressure and thus changes in the arrow direction allowing you to see the weather prediction.

What other information can we gather from the weather? Think of other tools used in weather reporting. Could they come up with something to measure rainfall? What about wind direction or strength?

...........................................................................................

I can't wait to try making our own Joanna, thanks so much for sharing! Off to go find some balloons so we can make one. Love it! Fingers crossed that our barometer reads sunshine for tomorrow!

We all love comments, so why not pop over and visit The Blue Barn her and tell her how much you enjoyed her post on Housing A Forest.
