Wax Museum 2021
Students dressed up as a president of the United States and recited important facts about each one for students, staff and parents. They all did an excellent job!
Water Cycle In A Bag
First, the class drew a sky in the upper half of the plastic bag and included clouds and the sun since they are important parts of the water cycle. Next, they added a couple of drops of blue food coloring to a cup of regular tap water and poured it into their bags. Then, they picked a window that got a lot of sunshine for best results. By hanging the water cycle bag in direct sunlight we were able to see water evaporate and condense into tiny droplets. When the droplets became bigger, they ran down the side of the bag like rain. The water pooled again at the bottom of the bag like it does with lakes and oceans.
Students used a Ziploc bag, permanent marker, water, blue food coloring and clear tape for this activity.

The Earth's Layers
Students in Grade 3 learned about the multiple layers of the Earth. They are, in order from the exterior to the interior - the crust, the mantle, the outer core and the inner core. These four layers all play a part in making our world work. The crust is the thin, outer layer of the Earth where we live. The next layer is the mantle which consists of very hot and dense rock and is much thicker than the crust. The Earth's outer core is made up of iron and nickel and is very hot. The inner core is the very center and hottest part of the Earth.
Students created a 3D model of the Earth by making a planet out of Play-Doh. When they were done creating the different layers, each student cut their Earth in half to reveal it in cross-section. Students used toothpicks and a label to identify each layer.

Build an Igloo
This STEM challenge was to build a model of an igloo. We started off talking about snow-covered areas like Alaska, parts of Canada and even northern parts of the United States. Then we discussed what igloos are made of and watched a video online about how they are built. Students used a lab sheet to sketch a plan before beginning. Then
they used paper plates, cotton balls, paper towel rolls and glue to build a circular based, dome shaped igloo with a door opening. Everyone was successful and had fun building an igloo with their materials.
Animal Adaptations
Students in Grade 3 learned how adaptations allow organisms to survive in certain environments. This activity allowed students to model and explore the way in which fat helps insulate an animal from a cold environment. We used vegetable fat (shortening) to model an animal's layer of fat and a cup of ice water in this experiment. Students spread the vegetable fat over one index finger, put it in the ice water and timed how long they could keep their finger submerged. They repeated the process with their other index finger without the fat. Students found that the fat-covered finger was more comfortable longer than the unprotected one. This experiment confirmed the fact that fat can help animals survive in cold environments.
