red yellow orange

Standard

So this week we’re learning about orange.  Yes, we are still in our farm theme – but it’s fall so I put this mini unit into the mix.  This past weekend I made a batch of yellow and a batch of red playdough.  As you’ve probably guessed, we are mixing the two together to get orange.  I give each child a little ball of yellow and a little ball of red and just let them play – most mix the colors, a few choose not to.  However, the color is coming out more of a red-orange then a true orange.  I should have made a batch and a half of yellow and a half batch of red because as it stands now the red is overpowering the yellow.  Oh well, I’ll have to mental-note that for next year.

Another activity we did was I put a squirt of yellow and a squirt of red paint into a small zip-lock sandwich baggie, sealed it, and gave one to each child to squish around.  After a bunch of manipulation we discovered that the two colors mixed and made orange!  Some children told me they already knew that would happen – but I could tell that for a lot of them it was a new discovery!  I loved the looks on some of their faces when they saw the color changing!

One of the last activities we’ve done so far this week is painting with yellow and red.  I put some red and yellow on a large piece of white construction paper and give them a paintbrush.  Almost every child mixed their paints and painted until their entire paper was covered in orange!  Then, when their painting was finished I put a strip of paper in the middle that read “Red + Yellow = Orange” – which made the kids excited because they had a “real” math problem on their paper!  (We had talked about the “+” and “=” signs as a group beforehand when we did the paint in the baggies and I wrote it on the board)

So far, a good start to our week!  🙂

blue yellow green

Standard

So this week we have been learning about the science of color mixing!  In honor of St. Patricks Day we have been discovering how to make the color green.  The past couple days we have been playing a lot with the playdough I made.  One little boy in my class got so excited when he saw the two colors mixing he yelled at the top of his lungs, “Hey – look at this –  I have green playdough now!  Cool!”  So, they have been slowly but surely making our blue and yellow playdough green – and loving every second.

Today we did a little color mixing at circle time.  I paired up each student and gave each pair a baggie with blue and yellow paint in it and told them to take turns squishing the bag in their hands.  At first they weren’t so sure – so I gave them some encouragement and soon they were squishing to their hearts content!  They were very excited about watching the colors blend and turn to green!  You would have thought it was magic the way they reacted – so cute!

We carried this over into art and started painting with blue and yellow paint.  Even on their paper they goit excited to see the green appear – although one would have thought they should’ve already known what was comming!  🙂  We will proabaly finish up the paintings tomorrow and will continue to play with the playdough the rest of this week and on into the next.  I love seeing their faces light up when something they are doing makes the change!  Gotta love it!

Wind

Standard

We are in the final couple weeks of our weather unit and today we talked about wind.  We talked about how you can’t see it but you can feel it.  You see what it does when it moves and bends things.  We went outside and observed what the wind was doing to the objects around us.  Then we talked about how we can make our own wind.  We talked about how fans make wind.  Then we asked if they knew how they could make their own wind.  After lots of guessing, one child finally yelled, “When we blow!”  Bingo!

So next we gathered 10 objects from around the room – things like a feather, a crayon, a block, a piece of yarn, ect. and asked the children to predict what would happen if they blew them.  Would these objects move in the “wind”?  After writing down their predictions, we tested their theories by having them take turns blowing the objects to see what happened!  Most of the predictions were right and the children were super excited!  We posted the chart of predictions and outcomes on the wall for parents and the children to look over.  The rest of the morning they were blowing things to see if the wind could move them!  What fun!
