This resource would be used as a lesson. It shows how putting objects in a way of light can make the light bend or go in different angles. I would use the activities in the resource to start off the lesson and ask the students to make conclusions of what they might think could happen.

In this activity you need a flashlight, A transparent container with flat parallel sides, and 250 milliliters (1 cup) of milk. There will be water in the container. Gradually as you experiment you will add more milk to the water. The water acts as the day time sky, the milk acts as the clouds, and the flashlight is the sun. As you add more milk it gives of the appearance of a more cloudy sky. The cloudier you make it the more orange the light will get. Basically the sun sets as you fill the container with more and more milk. I think this is an awesome idea. I have never seen this done before but I would have been amassed as a student to see this. it fits great with a weather lesson, a light lesson, or a lesson about clouds and cloud types. Depending on have advanced your students are you could probably ask them to give you examples of the cloud cover that might be present as you continue to pour in the milk. This is another good observation and journal point in class. Maybe you don't tell them right away what it is supposed to look like and you have them tell you instead. You could discuss how as clouds get thicker less light passes through and introduce terms such as transparent and translucent. Whether you tell them what it is or not it is a great connection to make with students. This is something that literally happens every day in their own lives. maybe you could have them go home with journals and compare the real sunset to the one you made in class today.

"Shadow puppets offer a great way of investigate light and shadows. It also links to literacy, storytelling and design technology. Try out this cross-curricular activity." This activity is a great way to demonstrate to students how light travels as a wave, showing them that when you put a shadow puppet in between the lamp and the wall, the puppet blocks some of the light waves. For this activity, I would have sample shadow puppets made along with a script to go with the characters. I would allow volunteers to work the shadow puppets as I read the script aloud. To boost the creativity of this activity, I would allow students to create shadow puppets of their choice. I think this would serve as a great extension activity to a lesson about light and shadows especially because it gets students engaged as it requires their involvement. To make sure students fully understand and grasp the relationship between the light and the shadow puppets, I would make sure that each student has a chance to use their shadow puppet on the "stage."

This is a lesson plan that will provide students with an understanding of how light interacts with different objects. While experimenting with different objects, students will be able to see the relationships between light and the shadow that the objects casts. In addition to learning about shadows, students will be able to tell if objects are reflective, transparent, or opaque. I like this lesson plan because it breaks down the lesson into multiple days and offers ways for the students to further their connections by experimenting at home. I would use this lesson in the classroom while teaching about sources of light.

This resource is my technology source. In this resource you are able to chose air, water, or glass. Then you press the light button which allows you to send a light ray or wave through one of those. You then can see how it reflects, bends, or bounces through each one of these. I would use this resource as part of a way to summarize a lesson. This will allow students to play around with it on the computer.

Our eyes are using light to see various objects all the time, but when this light travels through different mediums (such as water & air) it changes direction slightly. Light refracts (or bends) when it passes from water to air. I selected this resource because I could not quite find a good field trip. I feel like this is an easy way to show the young children how objects bend when looking through other material. This is a very easy lab and experiment for young grades. I would use this lab when showing my class how objects may appear and look different when seen through different objects.

This is a test which covers the basics of light bending and refraction. I selected this resource because I believe it would be a good way for students to test their knowledge about this topic. In my classroom I would use this as a way to introduce the topic.

This resource is an exercise in perception with a small nod to biology. Essentially, the activity requires a student to stand astride a 2x3-feet mirror and then, with the leg that is against the reflective side of the mirror, bend at the knee and move it back and forth. This will create the illusion of flight. The idea behind this is not only the reflection of light using a mirror, but it also ties in to basic biology and anatomy by proving that the human body is symmetrical. I chose this out of a desire to find fun light and reflection-based activities that are relatable to younger (K-3) students. I would use this in the classroom as part of a lesson about light and reflection, making sure to give the hat tip to the biology element as well.

As plants grow, they move up toward the light. But what is a plant's favorite color? Do plants move toward some colors more than others? Problem: Do plants bend toward certain colors of light? This experiment would be great for a 4th or 5th grade classroom for the students to see different plant behavior. I would definitely use this resource within my classroom as a project for the class to do throughout a period of time. I personally like this experiment because it will get the kids excited and interested because they have no idea what to expect or to even think a plant will grow more towards a certain color than another.

This is a video I found on YouTube featuring an experiment that shows how light can be "bent" using water and reflection. I selected it because it goes well with the Next Generation Science Standard that I was given (1-PS4-3). I feel that it lends itself well to explaining to students the reflective properties of light, and I would use the video along with my own version of the activity to explain this. I tagged both K-3 as well as 4-8, though I feel that the activity could be used at any grade level. The video itself uses more advanced language and vocabulary, but I feel that by using grade-appropriate terminology, it could be useful for younger students as well.

Ask students to look at a glass of water with a pencil in it and have them draw their observations. Tell them to look at the glass from all angles. Ask them to explain their observations and hypothesize the cause of this discrepant observation. This would be a good follow up lesson after the bending light lab/experiment. I would use this to introduce the lab and experiment. Then finish and summarize the lesson by adding the questions.

This video is about how light bends or bounces due to objects being placed in front of it. I selected this video because Bill Nye uses a fun interesting way of teaching science with certain topics. I would use this as the lesson, and then would follow it up with a worksheet for the class

This is a lesson on the properties of the electromagnetic spectrum. It is structured much like a lesson plan that we learned about in EDU 309, and as such, is easily broken down into individual parts. The lesson itself provides introduction to the electromagnetic spectrum, UV beads, prisms, and diffraction gratings, and also explains the origins of rainbows. I selected this resource because it provides a clear example of the use of the Next Generation Science Standards (despite its origins in California) as well as a valuable way for elementary students to look at the world around them in a different way. It also provides reading and mathematics connections. I would use this resource as a guidepost to structure my own lesson about light waves and the electromagnetic spectrum.

Excellent first post! you've got the hang of Diigo!

This website has 5 different experiments that students can do with plants. The experiments test the effects of light, water, food, talking to the plants, and soil content on the growth of plants. I selected this source because I think the experiments are good and will help students understand the best conditions of plants. It will help them understand that there are other components besides light and water that go into the growth of a plant. I would use this resource during a plant unit, likely in 3rd or 4th grade. This would be an ongoing project that could integrate measurement in math, graphing (with and without use of technology), and art (by drawing observations).  

I love this one! I really like plant experiments becuase these days, kids don't really get to appreicate and witness actual plant growth. I would any of these as ideas to use in my classroom.

Students use potatoes to light an LED clock (or light bulb) as they learn how a battery works in a simple circuit and how chemical energy changes to electrical energy. As they learn more about electrical energy, they better understand the concepts of voltage, current and resistance. I chose this because I never did this in school! This really seems like an exciting and engaging lesson/activity. This lesson could be done in separate parts, with the first part being lecture based (learning about electricity) and the second part being the activity with the potato. I like how this resource has follow-up questions at the end of the lesson.

This little demonstration is so simple and cheap! All you need is a clear glass, water, and a pencil or straw. Place the pencil in the water. Does it look like it may be broken? I would do this at the beginning of a lesson that is covering light. With having a discussion about the topic and the students having a visual in their head, it should help them remember the topics discussed.

This is a PDF of a science lesson that includes lessons on sound , light., and energy. It includes objectives and instructions for the students. I think this is a great example of a lesson that will be great for students in class to learn about energy and how it is produced. I would use this site as a resource for teaching mu students about energy.

This site provides videos about energy, light, sound, and heat. Students can click on a link and watch a cartoon video that explains what each one of the above subjects are and how they work. After the video is complete, students can take a quick test to test their knowledge of the subject. I would use this source in class as a pretesting measure or as an exit ticket to see if students truly understand the subjects or if they need further explanations.

From our small world we have gazed upon the cosmic ocean for thousands of years. Ancient astronomers observed points of light that appeared to move among the stars. They called these objects "planets," meaning wanderers, and named them after Roman deities-Jupiter, king of the gods; Mars, the god of war; Mercury, messenger of the gods; Venus, the goddes of love and beauty, and Saturn, father of Jupiter and god of agriculture. This activity assists students with facts and knowledge on how the solar system works. By providing a diagram that assists the student in the order and distance of each planet, this activity provides the student with a realistic vision of what outer space looks like. I believe that this resource can be used to help students memorize as well as find interested in how the solar system works and how each planet is arranged, what their made of, their distance from the sun, ect.

Edit your tag to be "solar system" so it is in one place. Remove "science" tag, as these are all science. Use teh grade level tags k-2, 3-5, 6-8, and/or 6-8 rather than broader ones like k-5.

© 2012 Clipart.com To understand how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another. This lesson is intended to give students a general idea of how heat is produced from human-based activities and mechanical and electrical machines. This is great! This is a wonderful lesson designed to help students understand how heat energy occurs. It allows several hands-on opportunities for students to explore to begin have an understanding about how heat is generated. I chose this particular resource because I never personally liked learning straight from the book, and however most topics need written clarification, I love how the students can explore and witness these on their own. I could easily see myself using this lesson within the classroom. I could assign the students to conduct exploration and then have them find new items that fell into the categories of: human activity,mechanical and electrical machines.
