Science: Climate & Seasons

The first two weeks of school we learned about Climate and Seasons using Layers of Learning, year 2 unit 1.

We read a book about how the sun makes the seasons.

We pulled the colors out of spinach leaves. We mashed up the spinach and then covered them in nail polish remover. We put a piece of coffee filter barely into the nail polish remover and then waited several hours. Eventually, we could see shades of green, yellow, brown, and red on the coffee filter.

We colored maps showing climate change through ice melt, a climate map, and El Niño weather patterns.
Science: Climate & Seasons

We put one cup of water and five ice cubes in jars. We put a sandwich baggie over one jar and left both in the sun for one hour. After an hour, we checked the temperatures of the water. The jar with the baggie over it was 12 degrees warmer than the jar without, demonstrating how the greenhouse effect works.

First Day of School!

Yesterday we went back to school for the 2017-18 school year. As is typical as we get back into the groove, the day was long, but good, too.

Cameron has seminary at 7:15 this year. That is so much better than 6! The boys and I got ready for the day and I made breakfast (cinnamon rolls) while he was there. When he got home, we ate breakfast while watching CNN10.

First Day of School!

Then we moved into the dining room for grammar and spelling. We are using IEW Fix-It Grammar (The Nose Tree).

First Day of School!

In addition to going over the sentences and copying them, the boys are also circling the letter chunks (like they did in Spelling You See the last couple years) and diagramming parts of the sentences.

First Day of School!

Then we did geography. We are studying Turkey (using Layers of Learning) for the next two weeks. We did map work.

First Day of School!

We learned about camel wrestling and made little paper camels.

First Day of School!

The boys did their on their own work including Spanish (for Cameron and Adrian) and Latin (for Fritz), math and reading.

First Day of School!

This year all three boys are assigned to learn about whatever they want however they want. Adrian has chosen to do science experiments and record what he learns. He played with the super absorbent polymer that is in baby diapers. He was fascinated by it.

First Day of School!

Adrian finished school about 2 and the other two around 3:15. Considering we went to taekwondo and so were gone for a bit over an hour in the morning and then had to make lunch and eat it before getting back to school, I figure that’s not bad for the first day of school.

For snack, we had some hazelnuts. Adrian was not impressed.

First Day of School!

For dinner, we had ajvar, a dip made with eggplant and red bell peppers, kebabs and rice, and kuru incir tatlisi (poached stuffed figs).

April & May Science Experiments

We picked animals to research and filled out report sheets on them (this is Fritz’s report on the blobfish).
April & May Science Experiments

We filled out some cladograms.

We looked at the bacteria in yogurt under the microscope. We left out a bit of yogurt overnight and then looked at it. We discovered there were a lot more bacteria on the slide the second day.
April & May Science Experiments

We identified whether plants from our yard were monocots or dicots.

We looked at a monocot and a dicot under the microscope.
April & May Science Experiments

We identified the body parts of a cockroach. We were supposed to do the same with a spider, but after months of watching for spiders, we never caught one (and only saw a few very tiny ones)!
April & May Science Experiments

We cut a banana in half lengthwise and put the halves in ziploc baggies. We added 1 teaspoon of yeast to one bag and sealed them up squeezing as much air out as possible. The yeast digested the banana into a soupy mess while the plain banana stayed firm and puffed up the bag a bit. (Cameron’s and my hypotheses about what would happen were completely wrong, but Fritz’s was right.)
April & May Science Experiments

We examined a mushroom and identified the parts and then dissected it.

We looked at a torn blade of grass under the microscope.
March Science Experiments

We looked at rhizobacteria under the microscope.
March Science Experiments

We made a terrarium in an empty pickle jar.
March Science Experiments

We picked two identical leaves off one tree. We put 1/2 cup of distilled water in one jar and 1/2 cup distilled white vinegar in another jar and added a leaf to each jar. We let them sit overnight. The next day, the leaf that had been in the water was bright green and still looked healthy while the leaf that had been in the vinegar was very dark green and a bit shriveled.
March Science Experiments

We planted four radish seedlings and watered one with pure water, one with pure vinegar, one with 4 parts water and 1 part vinegar, and one with 4 parts vinegar and 1 part water. The one with pure water kept growing, the one with pure vinegar died within a few hours. The one with mostly water tried to keep growing, but wasn’t healthy, and the one with mostly vinegar grew for a couple days and then died.

January Science Experiments

We looked at blood under the microscope. None of the boys were willing to prick their own finger so I ended up doing it.
January Science Experiments

We listened to each other’s heartbeats using the stethoscope. Little did I know when I bought that stethoscope in 1997 for nursing school that it would still be getting used 20 years later!
January Science Experiments

We used balloons to measure our lung capacity. We took really big breaths
and then breathed all the air out into the balloons. Not surprise that Cameron has the biggest lung capacity, followed by me, then Fritz, and Adrian has the smallest.
January Science Experiments

We moved our joints in all the different ways joints move.
January Science Experiments

We dissected a chicken wing, paying attention to the skin, fat, muscles, and bones and how they connect to each other.
January Science Experiments

We demonstrated how quickly bacteria multiply. We started with a sheet of
paper representing the parent bacterium. We ripped it in half showing that one
becomes two in 15 minutes. We ripped those in half making four in 30 minutes.
Then we ripped those in half making eight in 45 minutes and so on until after 150 minutes we would’ve had 1,024 bits of bacteria confetti. We graphed the exponential growth.
January Science Experiments

We sat still and contemplated the organ systems that were working inside our bodies.
January Science Experiments

We examined insect wings and looked at them under the microscope. (This is a cockroach wing. It’s strangely pretty.)
January Science Experiments

We made a to scale timeline of the geological time of the earth. It stretched all the way across the entire house. The beginning of time is at the door. The little circle at the bottom is the appearance of humans.

We shined a flashlight in their eyes to see how their pupils automatically constrict when exposed to light.
November and December Science Experiments

We demonstrated how the body wants to stay in homeostatis. They checked their pulse (Fritz’s was 72 beats per minute) and then exercised for one full minute. They checked their pulse again (Fritz’s went up to 108 beats per minute). Then they relaxed for five minutes and then checked their pulse one more time (Fritz’s had gotten back down to 78 beats per minute).
November and December Science Experiments

I told each of them their birth stories. Adrian apologized for being born 12 days late.
November and December Science Experiments

And, of course, we dissected a frog.
