The concept of the video is to show that when molecules are heated up they slow down and move farther apart, while the opposite happens when the molecules are cooled. The video shows and explains that by heating up the air inside an old, thick milk bottle and placing a hardboiled egg on top, the egg will be "pulled" unbroken into the bottle through the small opening at the top. The student explains that when the air inside is heated up the molecules spread far apart while the molecules in the cooler air outside of the bottle are compressed and practically push the egg through the opening. The student also does another demonstration that can be done safely at home, or in the classroom, by heating up the air in a glass juice bottle and placing a water balloon on top with the same results. She also shows that by cooling the air inside the bottle by blowing in it, the egg pops back out. I liked this video because the student is demonstrating and explaining to the grown ups the scientific principles involved. I also liked it because it provides a safe way to conduct the same experiment at home or at school. I think this is a great visual demonstration to add to chapters related to properties of matter. I would show the students the video and ask them how they think that worked. I'm fairly certain that a few would say it was a trick of some kind, so I would ask them if they thought we would get the same results or if something different might happen. I would then conduct the same experiment in the classroom.

This is a short audio-only clip that helps teach younger students about chemistry they can find in their own houses - specifically, the kitchen. The clip explains the various properties of water - solid, liquid, and water - and explains that all three, despite their three different forms, are all the same chemical. I chose this out of a desire to find grade-appropriate chemistry experiments for primary students, and I would use it in conjunction with video and a hands-on activity as part of a lesson on the three states of matter.

This is an interactive game the students can play either as a center in the classroom or even at home. It shows the students how important it is for plants to grow with a certain amount of sunlight and a certain amount of water. I would use this is a K-3 setting just because it is a very simple game, but also keeps them on their toes as to when the plant needs water and sunlight as well as how long it takes for plants to grow on a weekly scale. I would use this is my classroom as a center game or a resource for them to play at home to keep their minds going in science.

This website includes 9 lesson plans on how to conserve water. It includes objectives, resources, and the bulk of the lesson. This could be used when discussing reducing with students. I can see myself using this website in the future to help teach the concept to my students.

This is a quick and easy science experiment on what happens when it rains. This would be a good experiment to do after a lesson or two on rain or clouds. It shows how the "clouds" (shaving cream) get heavy with water and causes "rain" (blue food coloring) to fall. I would use this in my classroom because it's cheap, quick, and easy. Shaving cream is always a big hit in the elementary classroom!!

Pinterest is a wonderful blog site for almost anything, including future teachers. This is a weather experiment that has students understand how rain comes through a cloud. Fill the cup with water. Put shaving cream on top for a cloud. Explain that when clouds get really heavy with water, it rains! Then put blue food coloring on top of the cloud, and watch it rain. Students would enjoy this hands-on experiment and help them to raise questions about weather.

This is an experiment for students to make their own snowflake. I would use this in my classroom as an extension of a weather and seasons lessons. I would try to do an experiment involving an element from every season.

This is a great experiment for students to see the process of crystallization. It's a great way to bring in the idea of crystals being formed by an arrangement of molecules in a pattern. Using household items like borax, food coloring, water, and a few other materials makes it very teacher friendly. I would use this experiment in class to expand on the movement of cold vs. hot water. I could also tie this experiment in while discussing liquids/solids, precipitation, or chemical reactions.

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.

No matter how old you get everyone is always excited when you get to watch a Bill Nye video in class. This video concentrates on condensation. It provides an engaging introduction to the topic and also shows students that you can do the seemingly impossible (making a cloud in a jar) with science!

This resource explains how to make a tornado in a plastic bottle using only water and dish soap. I selected this resource because I thought it would be a good way to introduce weather patterns that can produce natural disasters. It's fun and interactive and is sure to grab my student's attention. After creating the tornado, I would use it to talk about wind and other weather patterns that can create tornadoes.

This is a great activity to make the concept of the water cycle hands-on. Students can watch the process right before their eyes over the matter of an afternoon.

Three Lessons About Energy I designed these three little lessons a long time ago to support a third-grade science curriculum (the particular textbook is now lost to us--or in other words I can't remember the name of it), but they could be used with any elementary students who are studying energy in science class. I like this lesson because it allows the kids to get up, move around, and become a part of the lesson. I would have the students start by slowly walking around the room, making sure to be careful not to run into anyone or anything. If I told them I was adding energy, they would speed up a little bit, and if I told them I was removing energy, they would slow down a bit. If I told them I was removing a lot of energy I would tell them that they need to stop and hold hands with anyone near them. At first the students wouldn't know exactly what they were supposed to be demonstrating. I would later reveal to them that they were water molecules and the energy I was adding and removing was heat. When they were moving slowly they were a liquid, fast they were a gas, and stopping they were a solid. This is a great example of learning by doing.

This is a game for kids to play about plants. In the game, the kids have to balance water and sun just right for the plant to grow or else it dies. This game is extremely beneficial for students to learn that plants need an equal balance of sun/water to stay allive. I would use this during the first part of my lesson.

By creating a beach in a pan, students are able to make observations about how erosion occurs in nature. Place rock and damp sand at one end of the pan. Place a brick under the pan on the end with the sand so that the pan is tilting. Pour water into the opposite end of the pan. With a sponge in the water, press down on the sponge to create waves that hit the beach. The students will then be able to observe what happens to the sand and gravel after the waves continue to crash into the sand. I chose this resource because it allows the students to have a hands on activity and watch erosion take place systematically.

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.

I liked this experiment because it involved an upcoming holiday, which students also seem to really enjoy (you could also do this experiment without involving Valentines Day.) This experiment is similar to the classic baking soda and vinegar. When you put a balloon on top of a water bottle that contains aka seltzer and water, the reaction bubbles form, they have nowhere to go and it fills up the balloon with carbon dioxide gas, inflating the balloon and showing the heart message. To use this in a classroom, I would have my students write down what they think is going to happen to the balloon and to the reaction. We could also try this experiment with a different type of liquid like sprite and see what happens.

This lesson actually contains quite a few good activities and gives a good chance to give lesson segments a try. It gives students a great chance to realize how powerful the sun actually is and how using solar panels can fix situations like flooding and the way that water is flowing. There is also fun options that involve melting crayons and sunscreen to show the impact that the sun has on our earth.

"Chemistry isn't just incredible ... sometimes it's edible, too! These crystal lollipops are a delicious introduction to some very lick-able chemistry concepts. Teach your child about saturation, evaporation, and crystallization with a simple kitchen concoction that will leave her hungry for more chemistry." Who doesn't love food? I know kids do! This website outlines the materials and process necessary to make crystallized lollipops. This allows for the students to understand concepts of boiling water, dissolving, super saturation, evaporation, etc. Science concepts can even be explained using something as fun as food-and the lesson can end with a yummy treat!

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.

"Is your fourth grader a hands-on learner? If so, just reading about the layers of the Earth may not be enough to inspire or even interest him. Turn the abstract lesson into a practical craft with the fun and colorful creation of dough earth layers!" This lesson plan lays out the layers of the Earth through the fun artsy craft of play dough creations. Basically the child will create their own personal batch of dough-incorporating color dye and close guidance. The student will then use their play dough to collaborate on the outer crust of the earth, the water, the land the inner core and the crust. Students are capable of physically making the play dough thin or thick in accordance to the knowledge of their information. They are applying their understanding of the earth and what it's made of basically at their own fingertips.
