Our new science unit is about electric circuits and how they work. For our first lesson, we made a list of what we already know about electric circuits, and then we made a list of what we wanted to find out. The next lesson we did was figuring out how to get a light bulb to work using only one battery, one wire, and a light bulb. Some people got it to work pretty quickly, other people took longer to discover how it worked. By the end of class, everyone was able to light their bulb. We got it to work by touching a wire to both ends (positive and negative) of the battery, and the light bulb needed to touch either the top or bottom of the battery and a part of the wire. The picture below is of someone lighting their bulb using one wire, one battery, and a light bulb.
Reminders:
Cassie's Mittens - We are collecting stuff for Cassie's Mittens where you can donate winter clothing accessories, like mittens, hats, gloves, scarves, boots, and earmuffs. Thursday, December 19 is the final day to bring your donations.
Warm Clothes - Bring warm clothes because it is getting very cold outside. We need to wear warm clothes when we are outside to prevent getting frostbite and to keep warm during recess.
P.E. Shoes - Bring snow boots for outside, but remember to bring tennis shoes on P.E. days. Our P.E. days are Monday, Tuesday, and Wednesday.
Sincerely,
Mrs. Johnson's 3rd and 4th Graders
