It is a big year in Science!
We will study the following units:
- Electrical Energy
- The Sun, Moon & Earth
- Using Microscopes
- Systems of the Human Body
Sun, Moon & Earth
After we studied how the Earth rotates on its axis and revolves around the sun, we made sundials to show how ancient people told time using the shadow of the sun.
The Human Body
We studied five systems of the human body -- skeletal, digestive, nervous, circulatory, and respiratory. Each student prepared a project and presentation on a human body system of their choice. We were seeking the answers to: What are the jobs of this system? What are the components of this system? How do these components work together? And how does this system work with all the other systems of the human body? Students had a range of options to share their knowledge -- project boards, Google Slide presentations, models... and here they are!
Sharing a STEM Activity with Our Third-Grade Reading Buddies
Our challenge was to build the strongest possible bridge using 25 jumbo popsicle sticks and 36 inches of tape. Our winner, I believe, was 600g!
Our Own In-Class STEM Challenges
The First Challenge: To build the tallest possible tower that will hold a basketball for at least one minute, using only newspaper and masking tape. Everyone noticed a big improvement in teamwork and in project results comparing our efforts to September's. Congratulations, everyone!
A Winter Challenge: On one class member's birthday, we selected a challenge to see which team could build the tallest balloon tower given a specified number of balloons of each shape and three feet of masking tape. All manner of inflatable architecture resulted, and a great time was had by all!
Spring Challenge: Many STEM challenges involve building the tallest tower or the strongest bridge or boat. For our Spring Challenge, we tackled motion. The challenge was, given a specified set of materials, how to build a marble chute where the marble would travel from the starting line to the finish line without going off track. The solutions were, as usual, ingenious!
In our Electrical Energy unit, we studied the sources of energy for our daily lives -- hydro power, wind, solar, fossil fuels, and nuclear. Then we moved on to the types of circuits -- parallel and series. We created different circuits in our classroom lab.
