Goal Sheet Please place

in front of your binder!

Keep your goals in mind throughout the quarter.

“Our lives are not determined by what happens to us but by how we react to what happens, not by what life brings to us, but by the attitude we

bring to life. A positive attitude causes a chain reaction of positive thoughts,

events, and outcomes. It is a catalyst, a spark

that creates extraordinary results.”

Try questions 1-13

You have 10 minutes

Independent Variables

• What is tested by the scientist

• What is changed by the scientist

• Also known as manipulated variables.

Dependent Variable

• What is observed• What is measured• The effect caused by the

independent variable.• The data• Also called responding variables

Controlled Variables

• Things that could change but don’t

• Kept constant (the same) by scientists

• These allow for a fair test.

Science Experiments #2


Read the information below and then answer the questions.

SpongeBob loves to grow flowers for his pal Sandy, who loves big, colorful flowers. He found a new brand of seeds coated with a special “booster” fertilizer that said it would produce huge flowers. He planted 5 of the new seeds in one container and 5 of the old brand of seeds in another container. He placed both containers on a sunny windowsill and watered them every day. He measured the diameter of each flower, which is shown in the chart.

1. Which group was the control?

2. What is the independent variable?

3. What is the dependent variable?

4. What is the average diameter for each group?

Old Seeds 10 cm 12 cm 14 cm 6 cm 8 cm

New Seeds 8 cm 14 cm 10 cm 12 cm 16 cm

5. Which seeds are the best for big flowers?
