Science: More (chemical) Reactions

Weeks 28 and 29 of school we learned about more (chemical) reactions using Layers of Learning, year 3 unit 17.

We played with pH papers. Fritz especially had a good time with that.

We watched tons of YouTube videos (including one of Cameron doing the Diet Coke and Mentos experiment almost a decade ago).



We put glow sticks in hot and cold water and then let them sit for a while. The one in cold water didn’t glow as brightly, but the one in hot water didn’t glow as long.

We put Alka Seltzer in water and watched how the temperature changed. It went from 72* to 64* in less than a minute.

We mixed baking soda and vinegar and timed how long the reaction continued while stirring and while not stirring. It took 8 minutes for the reaction to end when we let it sit, but less than a minute when we stirred it.

We did the Diet Coke and Mentos experiment. The fountain it made was impressive.

We mixed diced potato and diced liver with hydrogen peroxide to see which contained more catalase. The result: Definitely the liver!

History: Boston Tea Party

Weeks 28 and 29 of school we learned about the Boston Tea Party using Layers of Learning, year 3 unit 17.

We added to our timeline. For the first time we had to put some on the facing page because the main timeline page is completely full.

We did mapwork.

We decorated cookies to demonstrate taxation without representation. After they spent some time making their cookies as pretty as they could, I told them I was taking a tax of one cookie each and they had no choice in which I took. Then I told them we were going to vote on having a cookie party later in the day and on how many cookies they would each contribute to the party. They got to choose which ones they wanted to contribute. We talked about how the first way was like taxation withOUT representation and the second was taxation WITH representation.

We made a model of Faneuil Hall.

We watched lots of YouTube videos including the Boston Tea Party episode of Liberty’s Kids.


Third Quarter Done!

We completed the third quarter of the 2018-19 school year last Friday. We learned so much this quarter.

In history, we learned about the thirteen colonies, slave trade, South Pacific, and British India. In Geography, we learned about Central America, Brazil, Australasia, and India. In Science we learned about metamorphic rocks, gems and minerals, fossils, and chemical reactions. In the arts, we learned about settler sayings, Colonial art, principles of art, and classical music. As always, we started each day by watching CNN 10.

Cameron read (listened to) Blood on the River: Jamestown 1607 by Elisa Carbone, The Republic of Pirates by Colin Woodard, The Slave Dancer by Paula Fox, Why Dinosaurs Matter by Kenneth Lacovara, and Mozart: A Life by Paul Johnson. His grades were great:
History A
Geography A
Science A
Art A
English A
Math A

Fritz read Dark Enough to See the Stars in a Jamestown Sky by Connie Lapallo, A History of US: Making 13 Colonies by Joy Hakim, The Slave Dancer by Paula Fox, Dinosaurs in the Attic by Douglas J. Preston, Capturing Jasmina by Kimberly Rae. His grades were very good:
History A
Geography A
Science A
Art A
Piano A
Religion A
English B
Math A
Logic A
Latin A

Adrian read If You Lived in Colonial Times by Ann McGovern and June Otani, If You Lived When There Was Slavery In America by Anne Kamma, Dinosaur Detectives by Judith Bauer Stamper, and Chemistry: Getting A Big Reaction by Simon Basher. His grades were excellent:
History A
Geography A
Science A
Art A
Recorder A
Spanish A
Religion A
English A
Math A

Science: Chemical Reactions

Weeks 26 and 27 of school we learned about chemical reactions using Layers of Learning, year 3 unit 16.

We made aluminum hydroxide, a white gel, by combining water, ammonia, and alum.

We made green rust by combining steel wool and vinegar, letting it sit for a week, and then combining some of the liquid from that jar with ammonia.

We blew up a balloon using baking soda and vinegar.

We did a chemical reactions worksheet.

We made milk of magnesium by combining epsom salts dissolved in water and ammonia.

We watched lots of YouTube videos on chemical reactions.
