Mixed 10th grade review
Ten questions from across the year, a quick way to see what is secure and what needs another look.
Working scientifically
Interpreting data from tables and graphs
CCSS NGSS.SEP 4CCSS NGSS.SEP 5England: KS4 Working scientifically
Example
Study: Cooling coffee. Time (min) → Temperature (°C) 0 → 83 5 → 73 10 → 63 15 → 53 20 → 43 Estimate the value at 17.5, assuming the pattern between neighbouring points is a straight line.
- (53 + 43) ÷ 2 = 48
- So the answer is: 48
Answer: 48
Evaluating experiments (research summaries)
CCSS NGSS.SEP 3CCSS NGSS.SEP 6England: KS4 Working scientifically
Example
Experiment 1: A pendulum with a 0.5 kg bob was timed for 10 swings with string lengths of 0.25 m, 0.50 m and 1.00 m. Experiment 2: A 1.00 m pendulum was timed with bobs of 0.1 kg, 0.5 kg and 1.0 kg. In Experiment 2, which variable was changed on purpose?
- In Experiment 2 the different values are given for the mass of the bob.
- So the answer is: the mass of the bob
Answer: the mass of the bob
Plants
Xylem, phloem and transpiration
CCSS NGSS.HS-LS1-2England: KS4 Combined Science: Transport systems
Example
Xylem or phloem? It transports mineral ions.
- Xylem carries water and mineral ions up from the roots; it is made of dead cells strengthened with lignin.
- So the answer is: xylem
Answer: xylem
Builds on: Photosynthesis
Rate of photosynthesis and limiting factors
CCSS NGSS.HS-LS1-5England: KS4 Combined Science: Photosynthesis
Example
Which of these is NOT a limiting factor for photosynthesis?
- The main limiting factors are light intensity, carbon dioxide concentration and temperature.
- So the answer is: oxygen concentration
Answer: oxygen concentration
Builds on: Photosynthesis
States of matter
Specific heat capacity and latent heat
CCSS NGSS.HS-PS3-1CCSS NGSS.HS-PS3-4England: KS4 Combined Science: EnergyEngland: KS4 Combined Science: Particle model of matter
Example
How much energy is needed to heat 2 kg of water by 40 °C? The specific heat capacity of water is 4200 J/kg °C. Give your answer in J.
- ΔE = 2 × 4200 × 40
- = 336000
- So the answer is: 336000 J
Answer: 336000 J
Builds on: Melting and boiling points
Leads to: Specific latent heat (E = m L)
Forces and motion
Momentum (p = m v)
CCSS NGSS.HS-PS2-2England: GCSE Combined Science: Forces (momentum, Higher)
Example
What is the momentum of a 5 kg object moving at 2 m/s, in kg m/s?
- 5 × 2 = 10
- So the answer is: 10 kgm/s
Answer: 10 kgm/s
Distance from the area under a velocity–time graph
CCSS NGSS.HS-PS2-1CCSS NGSS.SEP 5England: GCSE Combined Science: Forces (Higher: area under velocity–time graph)
Example
A velocity–time graph rises in a straight line from (0 s, 0 m/s) to (4 s, 4 m/s). How far does the object travel in this time, in m?
- ½ × 4 × 4 = 8
- So the answer is: 8 m
Answer: 8 m
Builds on: Read velocity–time graphs: gradient and motion
Leads to: Uniform acceleration: v² − u² = 2 a s
Energy
Energy stored in a stretched spring (E = ½ k e²)
CCSS NGSS.HS-PS3-1England: GCSE Combined Science: Energy (elastic potential energy)
Example
A spring with spring constant 100 N/m is stretched by 0.05 m. How much energy is stored in it, in J?
- 0.5 × 100 × 0.05² = 0.125
- So the answer is: 0.125 J
Answer: 0.125 J
Use energy conservation to find speeds and heights
CCSS NGSS.HS-PS3-1CCSS NGSS.HS-PS3-2England: GCSE Combined Science: Energy
Example
A ball is dropped from a height of 5 m. Ignoring air resistance, how fast is it moving just before it hits the ground, in m/s? (g = 9.8 N/kg; give 1 decimal place)
- v = √(2 × 9.8 × 5) = √98 = 9.9
- So the answer is: 9.9 m/s
Answer: 9.9 m/s
Electricity and magnetism
Power and energy in circuits (P = I²R, E = QV)
CCSS NGSS.HS-PS3-1England: GCSE Combined Science: Electricity (energy transfers)
Example
A current of 0.5 A flows through a 10 Ω resistor. What power is transferred, in W?
- 0.5² × 10 = 0.25 × 10 = 2.5
- So the answer is: 2.5 W
Answer: 2.5 W
Earth and rocks
Seismic waves as evidence for Earth's layers
CCSS NGSS.HS-ESS2-3CCSS NGSS.SEP 7England: GCSE Physics: Waves (seismic waves, Physics only)
Example
At a seismometer, the S waves arrive 15 s after the P waves. Assume P waves travel at 8 km/s and S waves at 4 km/s. How far away was the earthquake, in km?
- 1/4 − 1/8 = 1/8 s per km
- 15 ÷ (1/8) = 120
- So the answer is: 120 km
Answer: 120 km
Weather and climate
Carbon footprints and ways to cut emissions
CCSS NGSS.HS-ESS3-4CCSS NGSS.HS-ETS1-3CCSS NGSS.SEP 5England: GCSE Combined Science: Chemistry of the atmosphere (carbon footprint)
Example
A car emits 120 g of CO₂ per km and is driven 15000 km in a year. How much CO₂ does it emit in the year, in kg?
- 120 × 15000 = 1800000 g
- 1800000 ÷ 1000 = 1800
- So the answer is: 1800 kg
Answer: 1800 kg
Builds on: The greenhouse effect and climate change
Space
The life cycle of stars
CCSS NGSS.HS-ESS1-1CCSS NGSS.HS-ESS1-3England: KS3 Physics: Space physicsEngland: KS4 Physics: Space physics (separate science)
Example
In the life cycle of a star much more massive than the Sun, what comes straight after "nebula"?
- nebula → protostar → main sequence star → red supergiant → supernova → neutron star or black hole
- So the answer is: protostar
Answer: protostar
Builds on: The scale of the universe
Leads to: The expanding universe and the Big Bang
