In grade four we learn about Plant Growth and Change in Science. This year, we thought we try something new and plant and EAT sprouts that we’ve grown right in our classroom. Tomorrow is the big day for our Diakon Radish sprouts – we’ll cut them, rinse them and enjoy!
It turns out… we love butter. We also think this simple machine is fascinating.
Inside the gear box, we have 36 cogs on one gear and 12 cogs on the other. This means that for every one turn of the handle, the paddles in the jug turn 3 times (36 divided by 12 = 3). That’s great bang for your buck! We get a ton of work done with very little effort.
This happened on Tuesday. One day of the week we have gym either outside or in our classroom. Yoga is a great way to test our flexibility and try challenging poses. Namaste.
This is a while back — but I snapped a few pictures, so I thought I’d share. Our red wrigglers have been working overtime, munching away on fruit and veggie scraps from our lunches.
We don’t have enough worms to feed them everyday, but we try to feed them every couple of weeks. No mess, no smell and a great way to discover how worms, bacteria and fungi help us to get rid of natural waste.
We also have reading buddies with Mr. Webb’s grade twos every week. We make terrific role models for good reading behaviors and get to work on our reading fluency as the same time.
Today, we used one of these to make butter from whipping cream.
Why? Well, we’ve been learning about gears in our Simple Machines unit and this machine is amazing! Take a look inside the gear box.
We learned that the gear ratio is almost 3:1. There are 35 teeth on the driver gear and 12 teeth on the driven gear (Michiaiah counted!) This means for every one time that we turn the handle, the paddles inside turn almost 3 times! This makes our work easier.
Here’s what happened…
First we took turns.
We checked our progress: Frothy cream anyone?
This looks better.
We strained away the buttermilk. Miss Woitas is having buttermilk pancakes for dinner tonight!
We rinsed off the remaining buttermilk.
Some of us were even brave enough to sample the finished product.
