How does the type of light affect water’s evaporation rate?
I think that (place your own hypothesis here).
(Your materials might be a little different. Use what you have.)
Eleven 9 ounce Solo cups
One Sharpie marker
Fill five cups with an equal amount of water, labeling the cups A-E.
Place cups in different places around the house.
Wait four days and then mark the water level.
Repeat steps 1-3 using five different cups labeled A2-E2. Put cups in the exact same places as the first five cups. Place A2 cup where A had been, etc.
After four more days, weigh each of the ten cups with the water in them, including a control cup with the original amount of water.
Average the two trials for each cup (A & A2, etc.) and calculate the percentages to see how much water evaporated.
(Fill in the blanks with the percentages you got from your calculations.)
Cup A: ____% evaporated
Cup B: ____% evaporated
Cup C: ____% evaporated
Cup D: ____% evaporated
Cup E: ____% evaporated
My hypothesis was supported by my experiment: (Place your own conclusion here.)
Type out the Problem, Hypothesis, and Experiment, etc., and display on left side of board. In the middle section, have the title of the project and photos or sketches of the cups of water and where they were placed. Also, graphs can be made on the computer displaying the results of the experiment. On the right side of the board, display the Results and your Conclusion.
This is a very interesting project! I imagine most people know someone who lived through WWII and have heard stories of what life was like during that period in history. What made this particular project interesting was that the student (actually my son) interviewed several people who lived during this time period. He received first hand information about what life was like and how so many people pulled together for the good of our country, even though they had to ration items and do without some items. Interviewing these people helped make this project come alive for him. We knew someone whose best friend was killed at Pearl Harbor on the USS Arizona. It was such a sad time in history for all those involved!
Another interesting factor was that we had actually been to Pearl Harbor, saw the short movie (which made it seem like we were really there and brought tears to my eyes), went through the museum, and bought memorabilia such as a copy of the newspaper which showed the headline “WAR!”
TIPS FOR THIS PROJECT:
Interview people who lived through WWII and get a first hand account of what it was like.
Get copies of pictures of people who served in the war to add to the project.
Read children’s books about Pearl Harbor. See list below.

Most kids are fascinated with volcanoes. When teaching about them, it is important to let kids make a volcano, have good pictures of real volcanoes, and if possible, a video, since most students are not able to take a field trip to actually see one. If you are fortunate to be on the island of Oahu in Hawaii, then you can hike up to the top of Diamond Head, an extinct volcano. We did this, and it was quite impressive. Or you can visit Hawaii Volcanoes National Park on the Big Island of Hawaii, which we also did, and you might get to see an actual lava flow. We didn’t get close enough to see a lava flow, but we did walk through the Thurston Lava Tube which was very interesting.
Here is a book we own that has many great pictures of volcanoes:
Use a large pan, 9 x 13. Place an empty 16 ounce bottle in the middle of it with the top off.
Using either papier mache, modeling clay, or salt play dough, make a mountain with vertical ridges around the bottle. Do not cover the top of the bottle. Paint brown and let dry.
Mix 1 tablespoon liquid dishwashing soap and 1 tablespoon baking soda in a cup and carefully pour into the bottle in the middle of the mountain. (If you’re brave, you can add a few drops of red or orange food coloring in with the soap and baking soda.)
Place the pan with the mountain outside. Add 1/4 cup white vinegar to the bottle and stand back. Your volcano will erupt!
For ESL students, be sure and label everything.
For Gifted students, ask higher level questions. There is a chemical reaction when the baking soda and vinegar are mixed. It produces a carbon dioxide gas (a chemical reaction) which is the same gas that a real volcano produces.
