As part of our unit on the AMERICAN CIVIL WAR we study slavery and it's effects. We integrated some math into cotton ginning by figuring out how long it would take us to gin enough cotton bolls to make a pair of jeans. Most of us would take between 4-7 hours!
OWL PELLET DISSECTION
To end our science unit on food chains and food webs, we got to dissect owl pellets. This was really fascinating and kind of gross! We were able to see the most recent meals of the owl by the undigestible parts left in the pellets. We found the skulls, bones, and teeth of mice, moles, and other rodents. At first it was sort of yucky but once we started finding things in the pellets, it was like a treasure hunt! SUPER COOL!
FOOD CHAINS AND FOOD WEBS
Our final science unit is all about the flow of matter and energy in ecosystems. We learned how the source of all energy is the sun, beginning with photosynthesis. We learned about food chains and food webs, producers, consumers, decomposers, and scavengers and got to see real life examples of these when SUU Animal Ambassadors came to our classroom to visit. It was soooo cool!
As part of our language arts and writing unit on Greek Mythology, we made these awesome paper mache masks!
CHEMICAL MAGIC? No, it's SCIENCE!
We created some new substances using chemical reactions. We mixed several different kinds of substances and watched for chemical reactions. Sometimes, when we mixed two liquids, we got a solid or a gas.
We conducted an investigation using frozen carbon dioxide (dry ice) where we learned about SUBLIMATION. This occurs when matter changes phases from a solid to a gas-skipping the liquid phase.
We conducted investigations in matter stations today. We learned about volume, buoyancy, displacement, density, temperature, and experimented with lots of different ways to measure matter using balance-pan scales, digital scales, and thermometers.
MAGIC CRYSTALS? NOPE!
IT'S A PHYSICAL CHANGE
We added water to some Potassium Polyacrylate crystals in different forms. The result was some substances that appeared to be different, but this was a physical change because we didn't create new substances. If the water all evaporated, we would still have the Potassium Polyacrylate crystals left in the bag.
CONSERVATION OF MATTER
We learned about conservation of matter during a phase change. We weighed Otter Pops, made predictions, then froze them. We discovered that even though Otter Pops expand when frozen, the weight remained the same because we did not add or take away any matter- just changed the phase from liquid to solid. Then we conducted an investigation using salt and sugar, weighed and dissolved in water. We will watch as the water evaporates and leaves us with salt and sugar crystals.
We made raisins dance as we learned about DENSITY and BUOYANCY in MATTER today. We observed that raisins would sink when dropped into seltzer water but then rise up to the surface only to sink again. This pattern repeated over and over. We observed that the carbon dioxide bubbles in the seltzer would collect in the "wrinkly" parts of the raisins, making them more buoyant so they would rise to the top, but when they reached the surface, the bubbles would pop and the raisins would sink again!
INTERACTIONS OF EARTH'S SPHERES
We learned about the 4 spheres of earth; the BIOsphere (living things), the HYDROsphere (water), the ATMOsphere (air), and the GEOsphere (rocks and soil). We did a station activity where we learned about examples of each sphere and how they interact.
HOGWART'S SCHOOL OF SCIENCE
Halloween was such a fun day! The day before Halloween we were sorted into "houses" in preparation for Halloween fun. We did some science experiments, had the Halloween Parade in our costumes, played Haunted House Escape Room, and Hogwart's Minute to Win It!
Will a Mountain Last Forever?
We simulated the process of weathering and erosion on rocks and mountains by shaking sugar cubes to see how rough edges on rocks were smoothed and how deposition occurs.
We conducted an investigation comparing thick and thin "lava" to see which kind causes tall and explosive composite volcanoes with pahoehoe lava, and which kind create shield volcanoes with aa lava. We discovered that when we blew air into the thick lava, it would create bigger bubbles that exploded at the top, while the runny lava create lots of little, gentle bubbles.
Our mission, if we chose to accept, was to closely examine pictures of a "crime scene" and the text that went along with to determine what happened, based on evidence. We learned that when we READ LIKE A DETECTIVE, we refer to the text often, and really delve into what the author is telling us, or not telling us, to really understand what the text is about.
STEM JELLO EARTHQUAKE CHALLENGE
As we studied how earthquakes work, and how they affect humans, we were challenged to create our own structure out of toothpicks, marshmallows, and gumdrops. It had to be at least 2 stories high. We then tested its ability to withstand an "earthquake" by placing it on Jello and shaking it. Then we determined what changes we needed to make to engineer a better building.
For Landform Day, we each brought a model of some kind of change to the Earth's surface; either a volcano, earthquake, sinkhole, tsunami, or landslide. It was so much fun watching each other explain our model and see what they did!
FALL FIELD TRIP AT
On our field trip we were looking for evidence of slow changes to the earth's surface. We walked on an extinct volcano near Navajo Lake. Then we went to Mammoth Caves and explored through the lava tubes.
SO MUCH FUN!!
WE KNOW ABOUT THESE!
We learned how scientists use dichotomous keys to classify organisms. We first practiced on our class, then we classified some animals, plants and insects, and finally, we created our own dichotomous keys by classifying candy. It was DELICIOUS!
We did a STEM Engineering extension for our lesson on experimenting. Using only one sheet of paper, we had to design, and redesign, a way for our guy "Bobby" (the bobby pin) to land as slowly and gently to the ground when dropped from above our heads. We drew our designs, tested and tweaked them, and had a lot of fun while learning about engineering, inventions, and that failure is just a way of learning and making things better.
WILL IT FLOAT?
We experimented today in science by trying to get a golf ball to float in water. We learned that in fresh water, the ball would sink, but if we dissolved enough salt into the water (matter), that the ball would float! We also floated some rocks and learned about DENSITY, BUOYANCY, and that when we dissolved STUFF (matter) into the water, we increase the weight of the water, even if we can't see the "stuff."
HOW OLD IS THAT TREE (cookie)?
As part of our science unit on process skills, we learned about measuring in both standard and non-standard units. We discovered that our classroom is about 7 students in length. We also learned that there are more than one way to estimate the age of a tree. We learned about diameter and circumference and used what we learned to measure trees and tree cookies.
HULA HOOP OBSERVATIONS
We kicked off our science study this year by learning about SCIENCE PROCESS SKILLS. One of these skills is Observing. For this lesson we got out the microscopes and magnifying loupes to observe ordinary objects up close. Then we went outside to collect our own specimens to observe. (We may have had to sacrifice a few insects in the name of science.) We used hula hoops to narrow our focus and drew everything within the boundary of our hula hoop. We noticed that when we observed very closely, there was more in that tiny area than we originally thought!
