A circuit is a complete path that electricity flows through. There is a source of electricity (battery). Conductors are the materials that allow electric current to pass through them easily. Conductors like the positive and negative ends of a battery. In a closed circuit, the electricity flows without any interruptions. Ohm’s Law: Voltage (V); Current[…]

– Cell wall: surrounds/protects cell (only in plant cells) – Cell membrane: controls movement of materials into and out of the cell (active/passive transport) – Cytoplasm: watery area of movement – Mitochondria: produces/supplies energy – Chloroplasts: contain chlorophyll (capture sunlight) [only in plants] – Vacuoles: store food/water/chemicals – Nucleus: regulars.controls cell activities – Nuclear membrane:[…]

Did you know that the ACT has a science section that tests your ability to interpret scientific data and make observations about the natural world? Photosynthesis: – Light + water + carbon dioxide –> oxygen and glucose – Occurs in chloroplasts – green pigment is called chlorophyll (only in plants!) – Uses solar energy and[…]
