Electrons Will Travel

Electrons will travel – given a source and a circuit.

That’s what Ms. Sparling’s 4-6 team science students are learning through a series of hands-on activities using batteries, wires, light bulbs, switches and more.

An electric circuit is an electric current – made up of electrons moving in a path – that flows continuously. It is formed with components consisting of conductors (most often wires) and a power source (such as a battery) and may also include load elements (like light bulbs.) Another important component is an insulator. Insulators protect people and other things from the harmful electric current flowing through a wire. Insulators are usually rubber, since rubber does not conduct electricity and is often used in insulated wires (aka rubber-wrapped wires.)

Ms. Sparling’s students first experienced the difference between open and closed circuits using a battery, insulated wires and a small light bulb. When the circuit was closed (with everything connected in a circle) the light bulb was lit; but when the circuit/circle was broken/open the light bulb went out.

Next students used critical thinking and problem solving skills to determine how to incorporate a switch into the circuit. (Ms. Sparling was available to help them attach wires to the switch, but the students needed to determine where the wires should be attached to create a closed circuit.)

The next step: exploring a series circuit versus a parallel circuit and how the brightness of the light bulb is affected.

Beloved Bear Inspires Grammar Lesson

Finding Winnie

Some of the best stories are real stories.

In this case it’s the story of Winnie, the black bear who inspired some of the best-loved children’s stories featuring a bear and his friends who live in the Hundred Acre Wood.

LGS 4-6 team students recently enjoyed the book Finding Winnie: The True Story of the World’s Most Famous Bear, by Lindsay Mattick. The book is a story within a story: a mother is telling her son a bedtime story about a Canadian soldier in World War I who stumbles upon a baby black bear.

Because the book takes place in a present day setting as well as the past, it provided an opportunity for a lesson on verb tenses.

Using verbs from the book, students identified “clues” which help identify the tense:

            Past tense:       -ed       (he jumped, she watched)

            Present tense:   -s       (he jumps, she watches)

            Future tense:   will      (he will jump, she will watch)

The students were challenged by some irregular verbs like “ate” and did very well.

Pooh would be pleased.
