Geography: South Africa

Weeks 34 and 35 of school we learned about South Africa using Layers of Learning, year 3 unit 20.

We found South Africa on the big wall map.

We did mapwork.

We watched lots of YouTube videos.

We put together a puzzle of South Africa’s flag.

We made Ndebele pictures.

History: American Revolution

Weeks 34 and 35 of school we learned about the American Revolution using Layers of Learning, year 3 unit 20.

We learned about some of the major battles of the Revolution and which side won them.

We added to our timeline.

We tried to make five-pointed stars, but made a mistake somewhere and ended up with six-pointed ones.

We discovered Fritz had no idea how to march when I told him to march around the room to Yankee Doodle.

We watched a YouTube video about the Treaty of Paris that ended the Revolutionary War.

Science: Oxidation and Reduction

Weeks 32 and 33 of school we learned about oxidation and reduction using Layers of Learning, year 3 unit 19.

We watched a couple YouTube videos.

We soaked pre-1982 pennies in salted vinegar. When we took them out they were nice and shiny, but within minutes they had grown greenish stuff over them. We put two silver ungalvanized nails in the vinegar and after about 15 minutes, they were copper colored.

We made a silver nitrate solution and added a coiled copper wire to it. Over the next few minutes, the solution turned from clear to blue and bits of silver grew between the coils. This is probably our favorite experiment we’ve ever done. It was really cool to watch it happen.

We started steel wool rusting in water with and without salt.

We watched a couple more YouTube videos.

We dipped apple quarters in plain water, water mixed with lemon juice, and water mixed with vitamin C. We left the fourth quarter undipped. We didn’t get to finish this experiment exactly because while we were waiting for oxidation to happen, my father, not realizing the plate of apples was an experiment, ate the undipped quarter and the quarter dipped in plain water. That was all right, though, because we’ve all see how apples brown and we were able to observe that, of the two that were left, the one dipped in lemon juice browned faster than the one dipped in vitamin C water.
