To start out our dinosaur exploration, I arrived at school with a giant papier mâché egg. I got this idea from Deanna Jump's dinosaur unit. This worked out really well timing-wise, because the Easter Bunny had just visited us ;) We talked about making inferences and used a recording sheet to record our ideas of what could be inside due to the egg's appearance. The recording sheet will be included in my dinosaur unit when it is all ready to go! After our initial inferences, I gave my students three clues, and then we made another inference and talked about how some of our guesses changed. We also had to talk a little bit about checking whether our inferences made sense... yes, the egg was white, but are polar bears oviparous?! While they were outside for recess, the egg hatched... and we drew a final picture of what was inside:

Here is a reminder of our first big exploration question:
1. Comment est-ce que les différents outils peuvent nous aider à...
- Faire des découvertes
- Résoudre les problèmes
- Changer l'apparence/la texture des substances?
Our first activity was one of the best activities I have done in my (short) teaching career! I made dinosaur eggs out of baking soda and enough water to make dough. I put a little dollar store dinosaur in the centre of each egg. I forgot to take a picture of the eggs when they were whole, but they were really great - a perfect weight and texture for convincing dino eggs. I placed them on a cookie sheet with a whole assortment of tools - paintbrushes, magnifying glasses, Q-tips, plastic knives and spoons, toothpicks, popsicle sticks, plastic tweezers, etc... along with an eye dropper and a little cup of vinegar. I told them nothing except to try whatever tools they liked to hatch the egg, and to remember to be a good partner (we did this in groups of 2-3). It only took about 5 minutes for the first group to get their dinosaur out (using the knife and spoon like a chisel). Their dinosaur was still covered in "egg", so they decided to drop it into the "water" (I hadn't told them what was in the cup) to wash it off. Well!!! The screams of excitement when the "water" exploded were just magical! Everyone was so excited and started immediately trying to make theirs explode, some using the eye dropper and some just dumping it all in the cup. This turned the solid eggs into goo, changing their appearance, and solved the problem of getting the dinosaurs out of the eggs and cleaning the dinos off. My students also discovered that what was in the cup was not in fact water. It was a super fun experiment and I HIGHLY recommend it!
|Just look at that joy and excitement!|
|Love when they change the worksheet to make it grammatically correct for their answer haha|
Another activity we did to practice using tools also came from Deanna Jump's dinosaur unit. We did a chocolate chip cookie excavation! Each child received a cookie, two plastic knifes, and a paintbrush and had to carefully extract all the chocolate chips from their cookie and count them. We have focused a lot on counting strategies this year and I was pleased to see them being used reflexively!

Enjoy your week!
