Simple Machines

The 5th graders learned about wedges and levers through a simulation! They were able to interact with the objects and move them, which showed the different results when a change was made. The students recognized that they use these simple machines in their daily lives, such as a door stopper, which is a wedge.

Measuring Lab

The fifth graders were introduced to the metric system by completing a measuring lab. The students all used linear measurement to calculate mass and volume. They measured the lengths, widths, and heights of block to be able to compute density as well.

Mini-Metric Olympics!

The 5th graders reinforced their measuring skills by competing in the Mini-Metric Olympics! The students had to go through six stations and complete an experiment. The six stations were Paper Plate Discus, Paper Straw Javelin, Cotton Ball Shot Put, Right-Handed Marble Grab, Left-Handed Sponge Squeeze, and Big Foot Contest. In each of the experiments, they had a task to do and like scientists, they had to measure using the metric system!

LED Light Bulbs vs. Regular Light Bulbs

This week, the seventh graders carried out experiments to see whether regular lights or LED lights were more efficient. The students split up into five groups. Each group had a battery pack with two batteries, six wires, three regular bulbs, and three LED bulbs. They had to set up different types of circuits, such as series or parallel, for both of the kinds of lights. They then used multimeters to measure the voltage in volts and current in amperes.

Catapults

The seventh graders had to design catapults that would be able to launch a marshmallow the farthest. They only had ten minutes to plan and work together to build their catapults. The materials they had to utilize were popsicle sticks, rubber bands, a binder clip, a spoon, and some marshmallows to test their structures.

Solar Power

The seventh graders learned about solar power and how it was affected by different aspects. Some of the aspects that impact solar power are weather, seasons, and location. Today, the seventh graders performed experiments to see how heat and light affected solar power. They used lamps and shined them onto small solar panels. They learned how to use multimeters to measure the amount of voltage the solar panels produced.

Aluminum Foil Boats

The seventh graders were given the challenge of designing an aluminum foil boat that would be able to float in water with marbles in it. They were given only fifteen minutes to come up with a design that would be able to withhold the most amount of marbles. They had two pieces of aluminum foil. One was for practice and the second one was for the real challenge. They came up with unique and different ideas. The winner was a rectangular-shaped boat with 107 marbles in it!
