Wagon train science and engineering project
We have been studying Lewis and Clark, the Oregon Trail, the Gold Rush , life as a pioneer etc. One of the hardships the pioneers had to face was fording rivers with their wagons & belongings. They had to take their wagons apart and cross the river- then rebuild them if they made it. So, as a science challenge the children were asked to build a wagon that could float and carry the most weight across our large bin of water. Everyone was given the same materials, a time limit and had fun! Enjoy!

Final Day for the K'nex Vehicles
Playground Slides- The boys make predictions and observations.
Taking the vehicles apart was a bit emotional.
K'nex Vehicles Experiment #2
Pushing the bottle on different surfaces.
We are all excited to check out the playground slide next!
The student books are complete. See them here.
Force, Motion and K'nex!
An Integrated Science Unit
The children were asked to build a K'nex car & test which will travel the furthest distance using two different ramps. ( Incline Planes). They will study friction, force and two variables that impact the car's distance. They will also test the car pushing an object down the same ramps. They will record mathematical data on their car, the ramps and their two trials using vocabulary and concepts taught during the unit. They were asked to share all their data , reflections & analysis. They will be asked to organize all their data, reflections, analysis, glossary of terms and more using Book Creator. For the writing assignment, they will be writing step by step clear directions about how to build their vehicle. Diagrams, pictures and video will be included.
Day 1 building, collecting data and photographing car from multiple angles.
Day 2 recording data and brainstorming words needed to write detailed directions. Day 3 will be Ramp day and measuring distance .
Reading & Learning about a few well known scientists
Final day of crystal science project
B.B. Crystal Project
Writing up our observations & conclusions after watching the crystal video below then reviewing our original hypothesis ended this experiment.
Observations of their own crystals included some data collection as well- weight in grams, size & inspection of crystal shape using a magnifier glass . The single crystals were very easy to see and draw. The children were asked to draw it and compare their snowflake crystal to a real snowflake using a ven diagram! They were surprised as they lifted their pipe cleaner out of the solution. ( You cannot see the crystals that formed when in the solution).. Wonder why? We then watched Bill Nye's video on chemistry!
Scientific Method and Crystals
This experiment had the children go through the steps of the Scientific Method. The hypothesis varied but the question was - Would Borax Crystals grow on a pipe cleaner and a string if all other variables were the same. The children filled out their worksheet, made their smart guesses, listed the materials, variables and wrote down their observations. We noted that the string floated and wondered what would happen! Then each child was given their own jar and using the same solution and methods hoped they could grow a Borax crystal for the next step in the process. We were very surprised by the video and what happened to the string! Watch CAREFULLY!
The Science Fair is Coming!
Packets coming home next week.
Projects due March 25th!
Preparation begins for the 4th-5th grade Science Fair Experiments. We started with with a song, a YouTube video, book , a quiz activity and some science! We studied many vocabulary words needed for their upcoming science fair project and the steps in the Scientific Method!

Candy Cane Science
An Independent Variable and a Constant Variable
This science experiment easily demonstrates the concept of an independent variable and the constant. Once we went over what a candy cane was made of, the concepts of the lesson & the recording/observation sheet, the children were to determine what were the variables and the constant. They then made a smart guess ( hypothesis). We then watched what happened in 8 minutes to our 3 candy canes. They were asked to draw and explain their thinking and why they thought the candy cane in the hottest water dissolved faster. There reactions below as they watch the candy canes start to dissolve are priceless. They ended the lesson trying to think of another experiment that might impact dissolving a candy cane when we return form break that has a independent and dependent variable.
Why did the hot water dissolve the candy cane faster? Everyone made that smart guess but no one could explain why… Can you?
