Science: Sedimentary Rocks

Weeks 18 and 19 of school we learned about sedimentary rocks using Layers of Learning, year 3 unit 12.

We watched YouTube videos about sedimentary rocks.

We let a piece of chalk soak in water and checked its weight every 5 minutes. In 15 minutes, it gained 2 grams. This showed us that some rocks can absorb water.

We mixed sand with epsom salts dissolved in water and left it in the window that gets the most sun for a week to turn it into a rock (we weren’t sure it would work because we were in the middle of several very cloudy days that week).

It worked!

We demonstrated how layers of sediment separate.

We dissolved some chalk in vinegar.

We identified sedimentary rocks.

We learned how a surface coal mine works.

Geography: Peru and Bolivia

Weeks 18 and 19 of school we learned about Peru and Bolivia using Layers of Learning, year 3 unit 12.

We found Peru and Bolivia on the big wall map.

We did mapwork.

We watched YouTube videos including on one the Nazca Lines.

We made our own Nazca Lines designs.

We decorated hats.

We watched lots of YouTube videos, including several on Machu Picchu.

We ate Bolivian Silpancho for dinner (it was so good!).

History: Settlers

Weeks 18 and 19 of school we learned about settlers using Layers of Learning, year 3 unit 12.

We added to our timeline. Some pages still have some space. Some are completely full.

We did did mapwork about Jamestown.

We watched YouTube videos about Roanoke and the Mayflower.

We watched YouTube videos about Plymouth.

And on building a wetu.

And then we made a model of one.

We did some mapwork.

We ate hasty pudding for lunch.

Science: Igneous Rocks

Week 17 of school we did a creative kids unit using Layers of Learning, year 3 unit 11. That was our last one week unit of the school year.

We made a sugar syrup and cooled one container of it in the freezer and one on the counter to show different types of crystals.

We watched YouTube videos on rocks.

We made rock candy by putting together various things representing minerals and then covering them in chocolate. They turned out yummy.

We sorted igneous rocks.

We learned about how igneous rocks form.

We made magma goo and extruded it through our fingers.
