Fossils and Dinosaurs

This week we are talking about dinosaurs and fossils. We talked about how dinosaurs came to be, when they lived, what modern animals they are related to, and how they became extinct.  To everyone’s delight, we set out our collection of replica dinosaurs. These replicas are from the Carnegie Museum series, ranging from 1:10 to 1:60 in scale, and painted to reflect scientists’ best guesses on what each dinosaur might have looked like. Accuracy in dinosaurs is very important at this age, as many of our students are already experts. Children also explored dinosaurs by cutting them out of play dough, counting and sorting them, reading many different books about them, and playing dinosaur games.

This week, we also talked about fossils and how they are formed, reenacting the cycle with play dough. Students were so inspired, they got fossil books to compare with the fossils in our outdoor classroom. Kindergarteners became paleontologists and used the scientific method to find “fossils” in chocolate chip cookies. What a delicious Kindergarten studio!

Valentine bags

Hands down, one of our students’ favorite days is when we get to meet with our Upper Unit Partners. Last week we worked on Valentine bags in preparation for the holiday. There were lots of hearts—and hugs!

The Structure of the Earth and Rocks


This week, students in Primary are studying rocks and the Earth. We talked about the three types of rock and how each type of rock is part of the rock cycle. Molten rock fromed beneath the earth’s crust is brought to the surface by volcanoes. After the lava cools, this igneous rock can be transformed into sedimentary or metamorphic rock. Then it can be pushed deep inside the earth again, where it will melt and the cycle will start again.

We demonstrated these three kinds of rocks with soft candy—adding pressure to simulate sedimentary rocks, some heat and pressure for metamorphic rocks, and a lot of heat for igneous rocks. We watched the components of dirt separate when mixed with water and allowed to settle and erupted our volcano model. We also sliced open a hard boiled egg to see that it has layers similar to our planet.

This topic has led to numerous drawings and the writing of books showing the incredible information gained by studying rocks.

Light and Sound

This week we are exploring light and sound! As part of our exploration of light we used a prism to separate sunlight into the colors of the rainbow. Children also used mirrors to bounce light from one surface to another, and found out what they looked like in a mirror that was convex or concave. Other students used a flashlight and colored plastic paddles to change the color of light.

When energy causes an object to vibrate, the vibrations travel through the air to our eardrums, and we hear a sound! We investigated sound in several different ways. Using a Slinky, we tried to imagine how sound travels through the air in waves. We explored the connection between the size and shape of an object and the sounds it can make, trying out a rubber band and box “guitar” and listening to the pitches of tuning forks.

Celebrating Dr. Martin Luther King, Jr.

On Tuesday we talked about Dr. Martin Luther King, Jr. and his significance in history. At this age, we try to find a gentle way to talk about this subject.

We began with a basket of eggs in a variety of colors. We gave each child an egg and asked them describe it—color, size, and shape. Then one at a time, we asked for the eggs back, cracking them into a big bowl. What we noticed was that while the shells of the eggs looked very different, for the most part, the insides of the eggs looked very much the same.

We talked about how this was much like people—we look very different, but on the inside we are very much the same. We told the children that this was the work of Dr. King, to spread the idea that he felt all people should be treated equally, regardless of the differences we might see on the outside. We all deserve love, respect, and a chance to thrive.

We finished our meeting by reading a book which contained an excerpt of Dr. King’s “I Have a Dream” speech.

Second graders have been busy learning the pentatonic scale, both aural and written, and have been learning to sight-sing different patterns. A pentatonic scale is a scale with only 5 tones. The word “pentatonic” comes from the Greek “pente” meaning 5 and the Latin “tonicus” meaning tone. Pentatonic scales are very useful in learning music theory as well as composing music. Most Western folk music is composed using a pentatonic scale.

Today, students were given cards on which were printed various patterns of solfege in the pentatonic scale: do, re, me, sol, la. Each student chose favorite patterns and arranged them in a way that sounded pleasing to them the only “rule” being that the song had to end on do. After some practice, composers became performers as they played their songs for the class.

Simple Machines

This week we began our science unit on simple machines. We discussed how simple machines were some of the very first pieces of technology that humans invented, in order to do more work than they could with their muscle power alone. We built a marble ramp to show how and inlined plane can move objects. Using Lego Duplo pieces, we built a seesaw that acts as a lever, allowing one Lego person to balance two Lego people on the other side of the seesaw if she is sitting further away from the center than they are. We also built a Lego car to show how wheels and axles allow us to move heavy weights along a flat surface. Gears, wheels with teeth, can be connected to cause a complex chain of events.

2018 Shop Local Cards Available Now

2018 Shop Local cards are here! Get them at Juniper,MOON Co-Op, the Oxford Farmers Market Uptown, and McGuffey Montessori School for only $15. This year’s card features benefits including…

—5% off every day at MOON Co-op
—10% off your purchase at Kofenya
—15% off one item at Juniper
—$5 day passes at Miami Rec Sports… and much more! For a complete list of the discounts available, go to

Although fundraising is a critical piece of McGuffey’s budget, it is also part of our school philosophy to act responsibly as a part of our community, and to pay it forward.

For this reason, McGuffey shares a portion of the proceeds with some of our favorite non-profit organizations—the Oxford Community Choice Pantry, the Oxford Farmers Market Uptown Sprouts Program, and the Friends of the Oxford Lane Library. These are organizations our students, families, and staff consider a valuable part of this community.

We also believe it is important to support our local economy, and, for that reason, have chosen a “Shop Local” theme for our card, and have sought businesses from Oxford and the neighboring communities to participate in this program.

McGuffey students, parents, and staff donate their time and talents to facilitate the production, sale, and distribution of the Shop Local card, so there will be no cost to participating businesses or our non-profit beneficiaries.

Thank you for supporting McGuffey, the other non-profits, and our locally owned businesses !

Muscles and Bones

We have a visitor to our classroom this week! He has lived at McGuffey for quite some time, and has been affectionately named “Brainless Bob.” He is a life-size plastic skeleton, which allows our class to see exactly what is going on underneath their skin. (We somehow forgot to take photo of him while he was visiting!)

As we have been talking about our skeleton, we learned that we have 206 bones in our bodies. Some are big and some are small. Our largest bone is our upper leg and the smallest is in our ear. We discovered that we could feel many bones in our bodies—our knuckles, hips, ribs, and shoulder blades. Bones give us shape and protect important organs like the brain.

One of the works in the classroom this week is a full set of human x-rays. Children can take time to browse each x-ray, comparing them to their own bodies. They can even build a complete skeleton out of x-rays!

We also talked about our muscles. We used a partially inflated ballon, stretching and releasing it to explain how muscles expand and contract. We learned that muscles are in our face and help us smile and make silly faces. We also learned that muscles are part of our digestive system starting with the tongue.

In the past six weeks we have discussed nutrition, digestion, respiration, circulation, muscles, and bones. Although it’s pretty complicated, we have a much better sense of how our bodies work!
