Warm Ups
A student wanted to see what would happen if they placed gummy bears in water, soda, and coffee. The student weighed 4 of the same color gummy bears first. Then they measured 150 ml of each liquid and placed the gummy bears in 3 of the same type of container. The student then weighed each gummy bear after 10 minute intervals 6 times.
1. Identify the independent, dependent, and control variables. 2. Write a hypothesis for the student's experiment using an If.....then.... statement. A student is conducting an experiment. In container 1 they put 25 g of fertilizer, a pea plant, and 200 ml of water. Container 1 is then placed outside in the sun. In container 2 they put 50 g of fertilizer, a pea plant, and 200 ml of water. Container 2 is then placed inside under a light for 24 hours a day. In container 3 they put 75 g of fertilizer, a pea plant, and 2oo ml of water. Container 3 is then placed in a closet.
1. Identify the independent, dependent, and control variables in the experiment. 2. Do you think this is a good experimental design? Why or why not? What could you do differently? 1. Identify the independent and dependent variables from the following hypothesis: If more laundry soap is added to the washing machine, then the clothes will be cleaner than if less soap is added.
2. A student is testing the reaction of vinegar and baking soda. In container 1 the student adds 1 gram of baking soda to 100 ml of vinegar. In container 2 the student adds 1.5 grams of baking soda to 100 ml of vinegar. In container 3 the student adds 2 grams of baking soda to 100 ml of vinegar. The student records how long a reaction time there is and records it in their notebook. Identify the independent variable, dependent variable and the control. Analyze the experiment taking place in the above picture, then answer the following questions. 1. What are the controls? 2. What is the independent variable? The experiment: There are two plants of the same type and age. One is placed for 20 days on a window sill. The other is placed in a closet for 20 days. You will measure the length of the plants once a week and describe whether it looks healthy (green and sturdy), each plant will get the same amount of water throughout the experiment.
1. What is the independent variable? 2. What is the dependent variable? 1. What is the difference between a hypothesis and a theory?
2. How was your first week of school? What did you like/not like? 1. Give an example of qualitative data.
2. Give an example of quantitative data. 1. Tell me one fact about the scientific method?
2. What type of experiments have you performed? 1. Are you familiar with google classroom? If so, how or when did you use it?
2. Tell me one fact you know about science or biology. |
