The students will continue explorations of the Investigation 1: Solids.
They finished comparing solids that roll with solids that stack which represented sorting solids on the basis of their shapes.
They will examine (during the next lesson) the factors that affect how far a solid rolls that was placed on a ramp. They will test, collect data and write conclusion of four rolling balls (rubber ball, ping-pong ball, metal ball, and large marble).
The next physical property that will be observed by the students is finding out which solids float and which solids sink. The recording of the data will be done on the Venn diagram. Also a probe related to the sinking and floating will be used that shows thinking of the students (argumentation in science). Basically, the probe is designed to find out if students recognize that an object or material that sinks can be made to float by changing its shape (for example: using modeling clay).
The students will finish Investigation 4: Soil Observations.
They need to observe and describe the structures and the functions of the red wigglers (composting).
They will start Unit 2: Forces and Motion. During the Investigation 1: Balance they will explore the concepts of balance, counterbalance, counterweight, and stability by balancing tag-board (two-dimensional) shapes. They will discover through experimentation that objects can be balanced in many ways and that counterweights can help balance an object.
The students finished Investigation 3: Take Me to Your Liter.
They are starting Investigation 4: The Third Degree with an observation of a discrepant event in order to communicate the need for a standard unit for measuring temperature. They will measure the temperature of room- temperature water in degrees Celsius. They will collect data on how fast water cools off with ice and graph their results (line graph).
During the investigation, they will also calculate temperature change from a positive degree to a negative degree and explain how they did it (Response Sheet). One math extension related to the temperature will be included into the Investigation 4.
Reminder for the Parents of Grade 3
Please join us at the meeting scheduled for Wednesday February 14th in Auditorium, at 8:30 AM as we discuss the individual science fair projects.
Note: The letters describing the meeting went home on Thursday, February 1st.
The students are continuing the Investigation 1: Electricity.
They will build and compare simple circuits with a focus on how connections are done. They will identify the essential components of an electric circuit, understand their functions and also test whether objects are conductors or insulators. They will learn the conventions for drawing schematic diagrams of circuits. They will analyze another students drawing of a battery and bulb circuit to explain why it will or will not light.
Note for parents of Students Grade 3 & 4:
It is again the time of year when the students of upper grades are starting to work on their individual science fair projects. The packets that contain information regarding to the individual science fair projects will be sent home on Thursday, February 8th. The packet will be available also our school’s website.
Information for All Grades:
The book “Next Time You See a Sunset” written by Emily Morgan that was sent to the Space Station in August 2017 was already ready by the astronaut Mark Vande Hei. In order to hear the recorded reading of the story, visit storytimefromspace.com.
