Kindergarten students have been performing experiments to see what types of objects float. Next we will be designing foil boats and testing them to see which design holds the most weight without sinking.
Our First grade classes experimented with Magnets in November to see what types of materials are attracted to magnets and to see that not all magnets are the same strength. They also learned that magnets have North and South poles. We have just begun our unit on Sound. Ask your child what the difference is between volume and pitch. First graders using tuning forks to learn about vibrations and pitch:
Second grade students have been learning about different forms of energy. We performed experiments using heat and light energy in November. Now we are studying Energy of Motion. We are experimenting with wind energy to move objects and observe how different sizes, shapes and materials affect how much energy is required to move an object.
Kincaid third graders have just completed the unit on Soil. Your student should be able to tell you the difference between weathering and erosion. We have had plenty of opportunities to see erosion happening in our community with all of the rain during November. The students practiced using balance scales and weighed three different types of soils (sand, loam and clay) to show that some soils are heavier than others. We also performed a percolation test to see which soil type allows water to pass through quickly and which soil type absorbs the most water.
Fourth grade has been learning about forces and motion. We designed catapults and launched marshmallows from them to learn about levers and simple machines.
Next we made “roller coasters” out of foam tubing. We used marbles on our tracks to study energy and motion. Each group was challenged to create a “roller coaster” with one loop. The marble had to go around the loop, reach the end of the track and be slowing down or stopping at the end of the track. The students had to determine how to adjust their tracks to have enough energy for the marble to make it around the loop but not so much energy that the marble was going too fast at the end of the track. We had lots of creative designs!
Fifth grade has been “lighting up” the classroom as we study electricity. We tested different set-ups of batteries and light bulbs to see what makes a circuit. Next we will be learning the difference between a series and parallel circuit and how a switch works.
