Add some science to your Polar Express Day with these three hands on activities!
This product includes a lab booklet and directions for three different Polar Express inspired science lab investigations.
Frozen Hot Chocolate
1. You will need an ice cube tray or small muffin tin, hot chocolate, water and “hot chocolate” made with cold water (“cold chocolate”).
2. Fill one cup of the muffin tin with each liquid and place the tin in the freezer.
3. Check on the liquids each hour until one of the liquids is frozen.
4. Document results.
1. The night before you do this experiment, freeze water in two cookie sheets to create your ice ramps and road.
2. You will also need two trains or cars and a “road” ramp. I like to use a binder as the road and under the ice ramp to keep the inclines consistent.
3. Set up two ramps. Hold a train at the top of each ramp. Let go of the trains to let them roll down the ramps. Don’t push your trains.
4. Document your results.
and the STEM extension...Stop the Train!
Students are provided with various materials (I randomly select these from things I have on hand: salt, honey, tape, rubber bands, yarn, popsicle sticks, etc.) and challenged to find a way to slow down the train on the ice ramp.
Students plan and test their ideas to determine what could work to stop the train!
