that the scientist doesn’t change or add the variable to

Ex. The plant with the white light

Conclusion

The results of the experiment; is your hypothesis “right or wrong”?

Activity!We have done many labs in this

class…

We have also talked about a lot of different experiments – with your partner, identify each part of each experiment – the first group to finish correctly WINS!
