Simple Machines work - April

-
These are some photos from Simple Machine work done in Room 306/Finlay.  In the earlier pictures, students are using K'Nex kits to make their own pulley design, then using the kit instructions to make various lever examples like scissors, a hockey stick and a wheelbarrow. 

In the later pictures on a different day, students have a "Rescue" challenge where they pretend they have to try to rescue a hiker who has fallen down the mountain. They have to built a stable platform that the hiker can crawl into, and a winch/pulley to send the platform down the side of the mountain and pull it back up with the hiker.

Harvest time for Room 306

Today we harvested our beets/beet leaves, radishes, kale, mint and basil.  Everything was so fresh and delicious!  A few leftovers are being offered for the school conferences.  Many students were surprised and disappointed to hear that by harvesting everything off these plants, we would have to uproot and kill them, or take all the leaves off and therefore kill them.  We are making way for another growing project: tomatoes! We are keeping our Morning Glory plants going, because the way they are climbing is just amazing!  It will be really interesting to watch where they keep growing, and what they manage to wrap around.
