4th Grade S.T.E.A.M.
Utah Habitat Tunnel Book4th Graders- This is a very important project that we do to learn the habitats of Utah: Wetlands, Desert and Forest. I would like you to choose one habitat and draw the landscape for the back ground, draw two plants from the habitat and attach them to the side of your book and draw one animal from your habitat and put it in the front.
Do the best you can and if you need help, send me an e-mail [email protected] |
Rainbow in a Jar
Ingredients:
2 cups of warm water 1/2 cup measuring cup 1 Tablespoon measuring spoon 1 1/2 cups of granulated sugar Red, Blue, Yellow and Green food coloring Tall thin glass or test tube- old glass cup, old water bottle, Straw 4 popsicle sticks Microwave |
Steps:
1. Measure a 1/2 cup of warm tap water into the four (4) jars 2. Add 2 drops of food coloring to each of the 4 jars 3. To the jar of red water, add 2 Tablespoons of sugar 4. To the jar of yellow water, add 4 Tablespoons of sugar 5. To the jar of green water, add 6 Tablespoons of sugar 6. To the jar of blue water, add 8 Tablespoons of sugar 7. Stir each of the jars to dissolve the sugar. If your water is not warm enough to dissolve the sugar put the jar in the microwave for 30 seconds at a time, stirring in-between until the sugar is dissolved NOTE: Dissolving increasing amounts of sugar you are increasing the density of the sugar water solutions. The jars started at the same level and now the blue jar looks fuller. 8. Pour about 1 inch of the blue water into the bottom of your glass bottle/ test tube/ extra glass jar. 9. Use your straw to gently drip green water onto the top of the blue water. (drip the water gently along the side of the jar just above the blue layer) 10. Use your straw to gently drip the yellow water onto the top of the green water. GENTLY!!! 11. Use your straw to gently drip the red water onto the top of the yellow water! Again, be very gently. If you are not gentle, the colors will mix together and you won't have a rainbow!!! |
Water has three states: solid, liquid, and gas. Water begins its journey in a liquid state, which we see as bodies of water. As the sun heats water, it becomes a gas, or water vapor, and travels up into the atmosphere in a process called evaporation. As water vapor continues its journey higher in the atmosphere it begins to cool and gathers in small drops forming what we know as clouds. This is called condensation. Once water vapor condenses, it forms droplets of water that fall to earth in the process of precipitation. We experience precipitation as rain, sleet, snow or anything in between! By using four everyday supplies, you can create and witness the water cycle right in front of your eyes!

A. The hot water at the bottom of the jar represents bodies of water on earth. Just as water evaporates from lakes, oceans, and other bodies of waters, the boiling water becomes vapor.
B. As it cools in the top of the jar, where the clouds are drawn, you see the process of condensation and the jar begins to fog.
C. After a few minutes of condensing, the “rain” drips down the side of the jar back to our body of water on earth, showing precipitation.
