I Wonder How Manduca Breathe

Take a deep breath and have your class construct working models of a lung! Using 500ml plastic bottles as the chest cavity, and balloons for the lung and the diaphragm, learners work in groups to make a model. The models help them to...

Young scientists transform themselves into rivers, oceans, clouds, and drops of water in order to explore the water cycle. After assigning and explaining to learners their different roles in the activity, the teacher reads aloud a...

Young investigators conduct an experiment using the scientific method. They see how many drops of water fit on a coin; have them conduct several different trials. This involves making a hypothesis, looking at controls, and introducing...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

Here is a fabulous set of teacher's notes that will make your next hands-on gravity and force lab fun and interesting. These notes provide you with three activities that allow children to make and test hypothesis regarding force,...

Over the course of 10 days, young scientists observe their cups of seed and soil—one that gets sun and water and one that gets no sun and only water. Then they reflect on the results of the experiment to determine if their hypothesis was...

Young scholars investigate gravity, force and motion. In this motion of objects lesson plan, students drop various objects from a jungle gym and collect, measure and observe their data. Young scholars describe the forces that affect the...

An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

Pupils pose their hypothesis, they ready their instruments, then record their observations. This is the science of sound activity. They move through 5 stations, each focused on a different element of aspect of sound. Check this activity...
