I've had loads of people asking why I only target C grades in some of my videos, asking if they're relevant to them, and requesting more higher tier content.
This video explains how it all works and why I've organised things in the way I have. Try the Snapquiz: Get the app at:
Plants. If you're not a microbe and you're not an animal, you are probably a plant.
There are about 300 thousand known species of plants. Because plants adapt so well to almost any climate, scientists needed a way to organize the hundreds of thousands of species. In the same way there is a system of classification for animals, there is also a system of classification for plants. What do plants have in common? Photosynthesis is the biochemical process that connects plants. There are two big biochemical processes on Earth: Photosynthesis and Respiration. Plants also have cell walls that are made of cellulose. Not only do you see plants everywhere in the real world, but they are also all over the scientific world. On a non-scientific level, farmers have been observing plants for thousands of years. National Botanic Garden (US Capitol Video)
Matter: Evaporation. Sometimes a liquid can be sitting in one place (maybe a puddle) and its molecules will become a gas.
That's the process called evaporation. It can happen when liquids are cold or when they are warm. It happens more often with warmer liquids. You probably remember that when matter has a higher temperature, the molecules have a higher energy. When the energy in specific molecules reaches a certain level, they can have a phase change. You might be wondering how that can happen when the temperature is low. The energy you can measure with a thermometer is really the average energy of all the molecules in the system. > Chemistry Activities and Games Free Downloads. Cool Sound Vibrations - Water Waves on a Speaker. Page 6. 81.04.10: Perception and Sense Organs A Writing Unit for Biology. Students in my biology classes are always interested in sense organs and perception.
The facts that butterflies taste with their feet and most mammals see only black and white fascinate them. What would it be like if we humans were like bats and used echolocation to find our food? Chemistry Tutorial :Writing Laboratory Reports. Key Concepts The term "Laboratory report" is usually abbreviated to "lab report".
Problem Solving - Word Problems. Khanacademy. Scaffolds for writing and talking are supports for communicating in science-specific ways that may seem unnatural for students.
We mean for example that writing causal explanations, talking in small groups about how evidence can be used to back up a claim, or critiquing the ideas of one’s peers in a whole class setting, are not the kinds of communication that students engage in outside of school. Tools can help—these take the form of sentence frames, guides for how to help ELL students practice final explanations, norms for whole class discussion that are developed by students, roles that students can take up in small group activity, and others.

With episodes no longer than 5 minutes, these videos take the traditional concepts taught in middle and high school science, engineering, and math (STEM) classes and puts them in a context completely outside the classroom. You won’t find a single equation in these videos - instead, they feature the gamut of hosts and personalities who will take you into labs, rivers, and the sky!
