This tool is a great supplement to a lesson. It gives a visual as to how an enzyme reacts in the cell as well as allows students to modify parameters to understand the effects of the change in environment. This can be used as review and accessed at home as well.

When you breathe in, your diaphragm - the muscle at the base of your lungs, contracts. This expands your chest cavity, lowering the air pressure of the cavity below the air pressure outside, and inflating the lungs. You can see this same principle at work in this 'homemade lung'. This activity will definitely keep students interested. It's all hands-on and will allow them to be able to visualize an action, breathing, that is constantly occurring within their own bodies. I chose this activity because I think so many don't actually understand what is happening within their own bodies, and by being able to visualize this action I think makes it easier to understand. This activity has the students making a "homemade lung" out of simple supplies and then observing how our chest cavities contract and our lungs inflate. I could see myself using this activity when discussing the human body, in particular lungs. It is so important that the students understand how the body functions and I think that this activity does a great job in illustrating that.

What a fun lesson on paleontology. In this lesson, the teacher will see that it can be cut into three class sessions. You have to make sure to have a good discussion about modelling prior to this lesson. On this page you will find the complete lesson on how to go about introducing fossils to your students. Their are awesome guiding questions and good ideas for how to display this lesson in and to the class. The activity sounds pretty cool as well. Students get to bring in everyday items or things they have at home and use them to mold into a fossil. This will start conversation between them on how each others look and how different items make different fossils.

This resource includes the information for attending a Planetarium show at the Saint Louis Science Center. This planetarium has a show currently being shown called "The Little Star that Could." The trailer for this video can be found at the site listed. I have attended many educational shows at several different locations, but none seem to ever compare to the ones shown at the Saint Louis Science Center Planetarium. The format of the presentation really resonates with the observers and leaves a lasting impression. I would invite my class to go on a field trip to this planetarium after a lesson on the solar system.

The Live Sky Tonight show at the Saint Louis Science Center could be an incredibly fun experience for students who are studying the night sky at home! In cooperation with creating some sort of sky map at home or at school using the internet as well as visual observations, both or either, the students could compare their own work with that displayed at the planetarium! This resource would serve as particularly helpful for visual learners who may benefit from this immersive model, and it might also encourage those who had not been as engaged in star mapping before to become more involved after the experience!

The Molecular Workbench provides an exciting opportunity for teachers and students. Students can choose which science they are interested in and then complete modules, which illustrate concepts through demos and asking questions to check for comprehension. Some of the questions are multiple choice and some are open ended, which will allow for curriculum differentiation. Teachers will be able to see not only if the students remember specific facts but also how deep their understanding goes. Plus, the demos and animations are interesting for the students!

LAB - Pig Dissection: This is an illustrated power point presentation that guides students through the dissection of a fetal pig. It includes identification of all external and internal features and structures. A great hands on activity for biology students learning about the body systems, I selected it for its practical applications and because the pig model closely simulates the human systems. Well labeled and extremely detailed.

InnerBody.com is a free virtual human anatomy website with detailed models of all human body systems. The Internet's best anatomy learning resource! This resource lets student interact with the human body in the different sunbject matter such as, muscular system, skeletal system, circulatory system and many more areas within the human body. This activity allows students to click on certain areas with the human body and the website increases that part of the human body in order to let the students explore and learn. I believe that this activity can help students study for their assessment as well as assist them within their memorization skills.

This activity is a little lengthy, but I would definitely use it with older elementary students. Students will build their own models of either a plant or animal cell by using Jell-O and fruit (or candy). If I were to use this in class I would modify the activity in a few ways. Making it a two day activity would allow for the students to pour their own molds, which would be kept in the refrigerator over night. Then students can label and stick the fruit into the finished mold on the next day. Either way, this activity is a great way to help students retain the different parts of a cell.

This lesson demonstrates a model of a species life cycle and how traits and the environment effects a species. Rather than looking at a worksheet that explains how traits are inherited or adapted due to the environment, this lesson allows students to see three generations of a species that they observe. Three different colored plastic Easter eggs and googly eyes are used for the outside appearance of the species. Two different colors of pipe cleaners are placed inside the eggs. The students make observations of color of the pipe cleaners and outer appearance. After their observation, they would write down their observation. They would take all the pipe cleaners out and throw them into a container. The next day they would come back to find what the next generation looks like.

This activity has each student growing their own plant. I was looking at the standards and I thought that this activity would work for 3-LS1-1, which says that students should develop models to describe that organisms have unique live cycles but have a common birth, reproduction, and death. I think that it would be interesting for the students to see how different plants grow from a seed and then develop unique characteristics. This activity would also teach the students responsibility, because they would be in charge of taking care of the plant. I would envision using this activity by splitting the students into groups and giving each of them a plant to care for, the students would also be in charge of keeping a weekly journal.

Mr Bones is - an interactive presentation geared toward an elementary school audience. A discussion of the human skeletal system presented by a physician, medical or graduate student using human skeleton model to demonstrate skeletal system anatomy and physiology. Common injuries and disorders of the skeletal system will be discussed as well as ways to keep the skeletal system healthy. This field trip would be a great opportunity for the students to learn about their body from the professionals. It would get the students out of the classroom and into a different learning environment for the day! I would try to plan this field trip to be before starting an anatomy or body system unit in middle school science.

I think this would be a great extension activity following a lesson over the phases of the moon as students will be showing their understanding of these phases using Oreo cookies. Each student is given 8 split Oreo cookies and one plate with the phases of the moon on the bottom of the plate. Students will use their spoon to move the cream off the cookie to model the correct phase of the moon. After completing eight correct moon phases with their cookies, the student will label each phase of the moon with the correct name strip which is provided. Once the student has correctly labeled the 'moons', they may eat the cookies and take the plate home. This is a great way to check and make sure students have an understanding of this material. It also makes it fun for the students as they are able to finish the assignment by eating their cookies!

This is an interactive exploratory app for kids to learn about the human body. Instead of offering lectures, this app allows kids to go into different parts of the human body, explore, play and observe. It offers many different activities that teach children how each of the different parts in the body work and it explains some of the functions and processes that take place within the human body. One of the activities included is the exploration of a working model of the body, as every part is interactive: the heart beats, guts gurgle, lungs breathe, the skin feels, and eyes see. I think this would be a fun interactive online activity to do in the classroom with the students. It would be interesting to have a class discussion over how the students believe each body part functions and what they think it is used for. Then we could explore the human body through this app and find out more about it. I think creating a KWL chart would work perfectly when using this app in the classroom. Although this would be a great app to use in the classroom, it would also serve as a great resource to use at home as it is designed for kids to discover what we're made of and how we work!

This activity combines science with visual arts as the students learn about animal habitats and then construct their own model of an animal habitat. The students will be assigned and given an animal (a small beanie baby), a shoebox to use as the habitat, and other materials to use to build the habitat. I believe that this would serve as a great extension activity to the zoo field trip I previously mentioned. This activity requires the students to use both their background knowledge and what they have learned or observed about these animals and their habitats. I feel that students would enjoy this assignment as it allows them to use their creativity.
