Here is an in-depth introduction to the Solar System and the planets that are in it. From the sun to why poor Pluto is no longer considered a planet, come along for a ride across the Solar System. FreeSchool is great for kids! I like this video for a number of reasons. One thing I really like about this video is how it gives the students an accurate perspective of the size of the different bodies in our solar system. It's also jam packed with a lot of great information about the solar system and builds on possible vocabulary words such as matter and mass. The narrator also has a soothing voice, which is a plus. I would use this video after spending a little time defining the necessary vocabulary of our solar system. We could follow up the video by making our own solar system that we could hang in the hallway.

Holding your nose while tasting the potato and apple makes it hard to tell the difference between the two. Your nose and mouth are connected through the same airway which means that you taste and smell foods at the same time. Smell is often considered the least important of our five senses, and I'm sure many students would agree. I would start by taking a poll which hopefully results in a consensus that smell is the least important sense. The following activity involves giving students small pieces of apple and potato and having a partner mix up the pieces while the other student's eyes are closed. The students will then eat the pieces with their eyes closed and try to see if they can guess which food it was. The students should begin to see for themselves how important smell is for tasting foods. This activity involves very few supplies and has an easy clean up. Afterwards, I would have a class discussion about their findings.

Salt water is denser than ordinary tap water, the denser the liquid the easier it is for an object to float in it. When you lower the egg into the liquid it drops through the normal tap water until it reaches the salty water, at this point the water is dense enough for the egg to float. I think this is a neat activity that kids would enjoy, and yet it requires very few supplies and clean up. I would first group students, giving each group a glass of freshwater and an egg. They would first put the egg in the freshwater only to see it sink to the bottom. They would record what they observed and possible reasons for why it sank. I would then give them another glass that is about half full along with a salt shaker. The students would be told to mix a lot of salt into the half cup and then slowly pour some of the freshwater into it. The egg is expected to float in this solution. The students would record their observations and possible explanations. This is a good way to start a lesson about density.

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.

While some of us stand out in a crowd others tend to blend in and it's the same in the animal kingdom. This animal camouflage lesson plan explains some of the concepts and offers a fun activity to help kids understand how camouflage works. This lesson involves learning about adaptations of animals in their environment. Specifically, we would be discussing camouflage. In the activity that goes with the lesson, students would make cardboard cut-outs of animals, color them, and try to hide them around the room in areas where their camouflage would benefit them most. Students would also learn how some animals prefer to stand out in their environment as a warning to others. For extensions of this lesson, we could discuss how hunters and soldiers use man-made camouflage. I could also take the kids outside and have them find somewhere that they would blend in the best based on their clothing.

Look at plants & what is needed for photosynthesis. What is the chemical reaction & what does it look like? Where does it all occur within the leaf? I could see myself using this interactive learning video for a lesson in photosynthesis. The video reads out loud to students, giving them important information about photosynthesis and then stops periodically to let them drag items, match terms, etc. I would let students explore using this tool, and then bring everyone together for a whole class discussion on what they learned. This could accompany a larger unit on plants, in which we could grow plants from seeds in a windowsill.

Why are bowling lanes oiled with more oil placed at the start of the lane and less at the end? What is the advantage of throwing a "hook" ball? Students participate in activities to learn about the members of their team and how to work together in order to be successful. There are several reasons I like this idea for a field trip. For one, it's an unconventional type of science field trip. Most students wouldn't think there is a lot to consider when bowling; they just toss the ball down the lane. Before the field trip, I would spend a day or two allowing the students to formulate and hypothesize ideas for how to best knock down the pins with a bowling ball. They would have to consider things like speed, angle, bowling ball weight, where the ball should hit the pins, and whether the ball should be hooked or thrown straight. This field trip allows the students to not only question and hypothesize, but to actually test their predictions. After the field trip we could delve deeper into some of the physics concepts at play (which the webpage has links for) as well as watch a professional bowler bowl.

Karen Pavlik discusses an inquiry-based lesson for an elementary weather unit. The students will predict which thermometer will have a higher temperature, one in a white sleeve or one in a black sleeve, and record their findings. I like this experiment because something is being tested, yet it has such a simple design. If I were to give this lesson, I would do a single experiment as a class, with one thermometer in a white sleeve and one in a black sleeve. I would allow students to write down their individual predictions beforehand regarding which, if either, would show a higher temperature after being left in the sun. I still remember a similar scenario from my early childhood years. One of my "alternate conceptions" was that darker would be cooler because shade is cooler. This lesson opens the door for further student inquiry and extensions to the lesson, such as testing different colors beyond just black and white.
