Today the 3rd graders had their first taste of energy labs for the 3rd trimester. Students will be looking at three types of energies: light, sound and heat. They will be exploring the properties of each type energy.
In light energy students are exploring the following ideas:
- light travels
- light reflet
- light refracts or bends
- light splits into colors
Take a look at Ms. Manliguis’s class as they explore the properties of light energy.

In the second trimester the 3d graders are learning about simple machines. In their first experiments they explored the lever. Here students were asked to balance their levers with particular objects. By positioning the objects of different weights in certain positions on each side of the lever, they were able to make the lever balanced. This took patience and precision and the 3rd graders were able to get all the lever challenges.
Science goes hand-in-hand with math. Before the students could work on inclined planes they learned how to use a spring scale and a protractor. A spring scale can be used to measure the weight of an object or how much force it takes to more an object. Many students had seen a spring scale being used to measure the weight of fish when family members go fishing. Students practiced weighing marbles and washers.
In their next lab students would have to measure the steepness of the inclined plane. In order to do that they needed to know how to use a protractor which measures angles. Students had mentioned previous knowledge of angles by using the math vocabulary such as obtuse, right and acute angles.
The most current simple machine is the inclined plane. They were asked, if you had to move a piece of heavy furniture onto a truck, would you use a steep inclined plane or a not-so steep inclined plane. Using their data that they collected students reflected on which ramp would be best and why. Students had to measure the angles of each type of ramp, 15°, 30°, 45°, 60°, and 75°. However in order to measure the degrees, students had a quick math lesson on how to use a protractor, a tool used to measure angles. They did great in their math lesson. Hopefully they will see how math and science go hand-in-hand.
Check out the video which showcases their level and inclined plane experiment.
One of the new web 2.0 tools that the teachers learned at our in-service yesterday was Tiki Toki. It is an online customizable timeline. Here participants can add “stories” to the event timeline. In our class today, we’re going to try it out. See the sample below of our Birthday Timeline. We’ll be adding our birthday to the timeline. This way, we can see if anyone has the same birthday.

Heat energy can make many things move or change. When an object is warm or hot, the tiny molecules like to move around and expand. When an object is cool or cold, the tiny molecules like to stay in one place or get close together. Take for example a thermometer. When the liquid inside gets hot or warm from the object being measured, it expands. The only place for the liquid to expand is up the tube. So what do you think happens to a thermometer when the liquid inside get cool or cold? Yep…it contracts or gets closer together. Thus making the liquid go down.
As the 3rd graders are learning how heat energy makes objects change or move, they explored this concept of expanding and contracting by observing what happens to a tea bag in cold and hot water. What do you think happened? See what they observed.
Here is the 3rd trimester finals schedule for grade 3 – 5.
4B Silva – Tuesday, May 8
4A Kala – Wednesday, May 9
5A Pai – Thursday, May 10
5B Ah Hee – Friday, May 11
3B Manliguis – Monday, May 14
3A Everett – Tuesday, May 15

The third graders are exploring the vibrations of sounds. Sound is created any time something vibrates. It could be a LOUD sound or a soft sound. It could have high or low pitch. Depending on what is vibrating, sounds will all be different. The third graders are trying to see which bottle would make the high and the low pitch sounds when filled with different levels of water. What do you think? Ask a third grader. Students were also given a chance to explore sounds with tuning forks. It made for a very loud morning in science as each student created ringing sound waves in the class. Check them out in this short video. Enjoy!
Finally a sunny day for the third graders to conduct their last light energy experiment. Using the sun’s light and a prism, students had to figure out how to position the prism in order to split the sun’s light into many colors, which would be a rainbow. Check out how the students figured out how to do it.
Let there be LIGHT! The third graders have finally jumped into action with experiments for the third trimester. Students are learning how light moves and what happens to light when it hits different medians, like glass, water, or mirrors. They explored how light can split when entering water and how it makes objects disappears or look distorted. In other experiments they tested with objects were transparent, opaque, and translucent. While in others they demonstrated how light travels in a straight line. Take a look at some of their exploration in science class.
The 3rd trimester started a few weeks ago and students are in full swing into their new units. Below are brief descriptions of what each grade will be exploring during the 3rd trimester.
Changes in Animals – How do animals grow and change? What is a life cycle? What is the life cycle of plants and animals? How do baby animals look similar or different from their parents?
Energy – How does the sun warm things?
Motion – Why do things move and fall? What are forces? What is gravity? What makes objects stop?
Magnets and Force – What can magnets do to other objects? What makes magnets attract or repel objects? How do people use magnets in their everyday lives? What is a force? What are magnets?
Forms of Energy – What are three main forms of energy? How does light move and what happens with it hits something? How does sound travel and move? How can heat make things change and move?
Work by Simple Machines – What are simple machines? How do simple machines make work easier? What are the 6 main simple machines and how do they work?
Energy and Transfer – What are ways that people use energy? Where does our energy come sources come from on the Island of Hawai`i? How does energy change from one form to another? How to use solar power to run a boat?

As the second trimester comes to an end (last day of 2nd trimester is on Thursday, February 16), final assessments will be coming up in the next week. We’ve already started having review games to help prepare for the final assessments. Remember these games are to review material covered during the trimester and give you an idea of what you need to study. Notebooks, papers and study guides are being passed back, which should be used to help you study.
If you still do not understand some of the concepts or have questions about your final assessments in science, please feel free to ask me. Do not wait to the day of your final assessment to ask the questions. Asking in advance will allow you time to reflect, explore more and soak in the information.
Though the trimester ends on February 16, some finals are scheduled after the date because I felt that some classes needed more time or science classes were missed due to huakai.

Here is the schedule for final assessments in science for grades 3 to 5.
