“Students were engaged the whole time, and using movement with work words to build vocabulary development was awesome! The real world application of digging a pool (something all kids are interested in) was a great idea. Plus the questions were appropriate for 5 and 6 year olds. They were so engaged on talking with a partner, very inquiry based. The machine pictures were so interesting, especially the world's largest excavator. They were completely enthralled! Putting a man in front was great to show the how large it actually is. ”

“Great 1st or 2nd lesson day activity. Got kids thinking about forces and motion but also OUT OF THEIR SEATS! YAY! Bonus is that their are no materials or set-up in this lesson, just "plug and play." Thanks!”

“Pretending to dig like the machine and pausing to discuss their estimation of how much dirt they had dug as a shovel vs. the excavator before revealing the picture of the hole. My students were so engaged!”

“watching the videos you showed & the online video links & my kids loved learning, dancing, drawing. it was a great morning learning activity to all learn together for all ages including for mom & dad! Thank you! I'm very excited about this website & what you are offering!”

“The kids loved the extra videos you included, especially the Excavator Song. They also had a lot of fun doing the movements of the shovel and excavator, great choice in getting kindergartners up and moving. They were very engaged!”

“The best part was the activity of kids going through the motions of digging machines...helped some realize the motions (pushing,pulling, moving, dumping) that machines do for us. Looking forward to the Force Olympics......”

“Doing the activity was the most fun and relevant for my K-1 ELL students. To make it more real, I had them pick up paper plates and move them as if they were an excavator and then I had them build one with connecting blocks that required pushing and pulling. The first graders also wrote as many work words they could remember. ”

“We loved the music video in the extras :-) Bringing the concept down to the kids by using a putting a pool in and how long it would take using a shovel vs. an excavator was excellent. I also appreciated the questions written in a way that is familiar with K - 1 kiddos - the highlighted words were a good tool to have the kiddos read aloud and concentrate on one word at a time.”

“My students were engaged the whole time. We did the writing extension and the online read aloud. They loved the dance along excavator song as a closing. Perfect well rounded lesson for kindergarten!”

“My kids loved this science lesson. They especially loved the acting part (pretending that they were digging with a shovel and then with an excavator.) They also really loved the Excavator Song. We must have listed to the song 20 times. ”

“This lesson was very clever and kept the attention of my kinder students. It was an excellent mix of passive and active learning activities. They especially enjoyed pretending to dig the swimming pool. Keep the K-1 lessons coming! ”
