Respond to the questions and prompts in the orange boxes. Vocabulary: Coulomb’s law, electrostatic force, vector Prior Knowledge Questions (Do these BEFORE using the Gizmo.). Have you ever taken clothes out of the dryer and found a sock stuck to your underwear? Static cling is an example of electrost...

1. General The mark scheme for each question shows: • the marks available for each part of the question • the total marks available for the question • the typical answer or answers which are expected • extra information to help the examiner make his or her judgement and help to delineate what is acceptable or not worthy of credit or, in discursive answers, to give an overview of the area in which a mark or marks may be awarded.

Figure 1 shows the apparatus used for measuring the rate of oxygen consumption in aerobic respiration by seeds. For the first 10 minutes, the tap attached to tube A was left open and the syringe from tube B was removed. Suggest three reasons why the apparatus was left for 10 minutes.

Define genotype. tion Define genotype. The genetic constitution of an organism. tion Define phenotype. tion Define phenotype. The expression of an organism’s genetic constitution, combined with its interaction with the environment. tion What is an allele? tion What is an allele? Different forms of a particular gene, found at the same locus (position) on a chromosome. A single gene could have many alleles. tion How many alleles per gene do diploid organisms carry? tion Ho...

Student Exploration: Waves Vocabulary: amplitude, compression, crest, frequency, longitudinal wave, medium, period, power, rarefaction, transverse wave, trough, wave, wavelength, wave speed Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A buoy is anchored to the ocean floor. A large wave approaches the buoy. How will the buoy move as the wave goes by? A buoy will move down and up as the wave goes by. 2. The two images show side views of ocean waves. How are the two sets of ...

Student Exploration: Carbon Cycle Vocabulary : atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geosphere, greenhouse gas, hydrosphere, lithosphere, photosynthesis Prior Knowledge Questions (Do these BEFORE using the Gizmo.) In the process of photosynthesis , plants take in carbon dioxide (CO 2 ) from the atmosphere and water (H 2 O) from the soil. Using the energy of sunlight, plants build molecules of glucose (C 6 H 12 O 6 ) and oxygen (O 2 ). Make sure all of ...
