2. Essential Question: Can light pass through all objects? 1-PS4-3 Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light. 1-PS4-3 Waves and Their Applications in Technologies for Information Transfer

3. 1-PS4-3 Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light. Alignment ReadingMath CCSS.ELA-Literacy.W.1.2 Students can use what they learned in the investigation to explain transparent, translucent and opaque. CCSS.ELA-Literacy.W.1.7 Students can write a “how to” book to determine if an object is transparent, translucent or opaque. CCSS.ELA-Literacy.W.1.8 Students can use their background knowledge and experiences to gather information about the pictured scenarios. CCSS.ELA-Literacy.SL.1.1 Students can discuss the pictured scenarios. CCSS.ELA-Literacy.L.1.5.b Students can categorize and classify objects based upon whether they are transparent, translucent or opaque. CCSS.Math.Content.1.NBT.A.1 Students can read, write and represent numerals that are covered on a 120 Chart using opaque objects such as aluminum foil squares. CCSS.Math.Content.1.MD.A.2 Students can use a flashlight to shine a beam on a piece of paper in order to measure the distance that their beam will travel before it no longer shines on paper. CCSS.Math.Content.1.MD.C.4 Students can graph to answer the essential question “Do you think light can pass through all objects?” (yes or no). Students can graph data before completing the investigation by answering the following question: “Which object will light shine through the best?” CCSS.Math.Content.1.G.A.2 Students will create a composite shape out of their pattern blocks (ensuring that their shape can stand). Students will shine a flashlight to create the new shapes shadow. Students will draw or trace this shadow or use technology to take a picture of the shadow. Students can write about their composite shape and it’s shadow by incorporating math vocabulary. 1-PS4-3 Waves and Their Applications in Technologies for Information Transfer

11. Identifying Evidence to Address the Purpose of the Investigation Lesson 2: Students will investigate with a flashlight and various other objects to make observations about the materials (include a piece of saran wrap, wax paper and aluminum foil in these) and sort the objects. Examples of groups that they make may be see-thru and cannot see-thru. (Vocabulary is not introduced at this point.) Create a tri-foldable by having students create the following using scissors, saran wrap, wax paper and aluminum foil still without introducing the vocabulary transparent, translucent, opaque. Have students investigate what happens when they shine a flashlight through the three “windows” on the foldable. 1-PS4-3 Waves and Their Applications in Technologies for Information Transfer

12. Planning the Investigation Lesson 3: Introduce the vocabulary transparent, translucent, opaque (see vocabulary slides) after students have investigated. Have students complete their foldable by labeling each “window” and writing about their findings. Students will re-categorize the objects to determine if the objects are transparent, translucent or opaque by completing the chart. (See Slide 13) Objects may include various items found within the classroom such as materials made out of: cardboard, wood, clouded plastic, wax paper, plastic, clear glass, mirror, water, different colored paper and/or saran wrap 1-PS4-3 Waves and Their Applications in Technologies for Information Transfer

20. 1. Go into a dark room (turning lights off is fine). 2. Fill the bowl about 3/4 of the way full of water. 3. Stick the mirror into the water so that it is standing up at about a 45 degree angle. 4. Shine the flashlight through the water aiming for the mirror. 5. Now look on the walls, floor, and ceiling for rainbows. How many did it make? How many of the seven rainbow colors do you see? Hint: If you don't see a rainbow, tilt the mirror more. You may need to aim the flashlight differently as well. Keep adjusting till you create a rainbow. How to: PS4-3 Optional Activities
