At the beach the tomatoes en the carrots don’t grow. The tomato’s grow with fresh water. We think plants with to much salt are goining to died. |
Research Question |
We want to now if tomato’s grow better with fresh or with salt water. Or how much salt water the plants can have before they died. |
Predictions |
We think the tomato’s grow not so fast if she has got salt water. We think the plants are died if they have 60% salt. Our teammates think the plants are died with 10% salt. |
Experimental Design |
We have six tubes with different presses of salt. We put every tube in a tray with plants. Some on have for example 60% salt and 40% fresh water. Another have for example 20% salt and 80% fresh water. We look now which plant grow faster and grow better |
