Ms. Wagner loves to eat tomatoes. She wants to plant a garden and is trying to figure out how to grow plants with more tomatoes. She plants three different pots of tomato plants and gives them different amounts of fertilizer. She keeps everything else the same (the amount of water, the amount of soil, amount of sun the plants get). For one month, she records how many tomatoes each plant produces. what is the Independent Variable:
what is the Dependent Variable:
what is the Constants:
what is the Hypothesis (If...then and because)

Independent variable: amounts of fertilizer.

Controlled/ Constant Variable: The amount of water, the amount of soil and the amount of sunlight.

Dependent Variable: how many tomatoes are produced on each plant

hypothesis: If you add too much fertilizer into a plant then the plant will overgrow too quickly leaving the plant with a poor structure for nutrients and water

explanation:

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
