Science Grade 1

 Sunshine and Shadows

 

Description: Students will use science inquiry skills to explore sunlight and shadows. They will learn what they need to make shadows, how to change and move shadows, and how shadows move outside as a result of the changing relative position in the sky.

Content Standard:

Expected Performances:

 

Grade Level Expectations (1st Grade): 

·       1.4 Observations can be expressed in words, pictures or numbers.  Measurements add accuracy to observations.

·       1.4 Metric rulers are used to measure length, height or distance in centimeters and meters; customary rulers measure length, height or distance in inches, feet or yards.

Science Integration:

Science Inquiry: Students in this unit use base knowledge to make inferences about manipulating shadows. They will also make predictions and record data.  They will use their observations to decide whether or not their guesses were correct, and measure their results.

Science Literacy: In this unit students will read fiction and non-fiction texts related to the unit. They should be encouraged to identify the main idea (A1 Literacy Standard) of the text, and to make connections (C1 Literacy Standard) with what they have learned about in class and other texts. The teacher can also question the students about why the author included specific sections in the book (B2 Literacy Standard).

Science Numeracy: The students will be using math skills such as identify quantities as equivalent or nonequivalent (CT Math Standard 1.3), describing, naming and interpreting direction and position of objects (CT Math Standard 3.2), using standard units of measure to communicate measurement in a universal manner (CT Math Standard 3.3), organizing data in tables and graphs and make comparisons of the data (CT Math Standard 4.2), and determining the likelihood of certain events through simple experiments and observations of games (CT Math Standard 4.3).

Instructional Strategies That Work:

Letting students lead the discussion with the teacher acting as a guide, allowing students to experiment and then demonstrate their findings, bringing students outside and allowing them to experience the effects of sunlight and shadows, allowing students to work together cooperatively, encouraging students to record data and use math skills to quantify data.

 

Vocabulary Words:

Light, shadow, surface, object, opaque, transparent, measure, length, centimeter, inch, sundial, “relative position”

 

Connections to Literature:

Nothing Sticks Like a Shadow, Ann Tompert

Me and My Shadows, Elizabeth Adams

 

 

Overview of Lessons:

 

Lesson One: Students will determine what is needed to make a shadow.

Lesson Two: Students will determine the necessary order for the surface, shadow, and object to create a shadow.

Lesson Three: Students determine that not all objects cast shadows.

Lesson Four: Students learn to manipulate the position of shadows.

Lesson Five: Students learn to why shadows move outside.

Lesson Six: Students use their knowledge of how shadows move outside to make sundials.

Lesson Seven: Students learn to manipulate the size of shadows.

Lesson Eight: Students will learn to manipulate the length of shadows.

Lesson Nine: Students will learn to manipulate the light source so that the shadow disappears.

Lesson Ten: Students will experiment with making shadows with two light sources.

 

Culminating Activity:  Students will play “Shadow Simon Says”, a game which will allow the teacher to assess their understanding of all the concepts they have learned in this unit.
